Enhance customer experiences with Apollo GraphOS


<p>Today we&#8217;re introducing <a href="https://github.com/apollographql/apollo-mcp-server">Apollo MCP Server,</a> enabling AI systems like Claude and GPT to interact with your organization&#8217;s APIs through GraphQL. While you can learn more about how to get started here, I wanted to share why we think GraphQL enabled by Model Context Protocol (MCP) will be an essential part of a modern AI stack.</p>

<p>MCP – a new protocol that standardizes how LLMs interface with external systems – opens the door wide open to agentic applications. APIs are the entry point to capabilities: adding items to carts, checking order status, scheduling appointments, updating inventory. When AI can reliably interact with these systems, we unlock an entirely more capable kind of software where natural language becomes the interface to complex business operations. MCP makes this possible by providing the connective tissue between AI&#8217;s language understanding and your API infrastructure.</p>



<p>One approach to MCP is to build an MCP server for each API you want AI to access. Your payment API gets its own MCP server, your inventory system gets another, customer data gets a third. It&#8217;s a straightforward way to get started. Most teams can build an initial MCP for a service reasonably quickly and LLMs support multiple MCP tools. It makes for a compelling experience.</p>



<p>As we’ve worked with teams pushing from prototype to product, we&#8217;re discovering that complex AI systems need more than what is possible by directly connecting individual APIs through MCP. We&#8217;ve found four particular requirements that show up consistently:</p>



<p><strong>Deterministic execution</strong>: An AI will often have to call multiple APIs in sequence and filter the results to just the appropriate fields for the user. This execution pattern needs to work exactly the same way every time for consistent, correct user experiences. Consider an AI returning purchase history – you can&#8217;t have one customer seeing five past orders while another sees three, or some results including shipping details while others don&#8217;t. We&#8217;ve also found that the more focused you keep the AI&#8217;s context, the better results you get. When APIs return large objects with hundreds of fields, the extra data can lead AI down unintended paths. Limiting data to exactly what&#8217;s needed keeps the AI on track and improves overall response quality.</p>



<p><strong>Policy enforcement</strong>: Giving AI direct access to individual APIs makes it difficult to enforce appropriate limits and access controls. A rule like “only loyalty members have access to the detailed shipping tracking information for their outstanding orders” can’t easily be written in the API layer, as it relates to a specific combination of data spread across multiple systems.</p>



<p><strong>Efficiency</strong>: Even simple customer queries can generate thousands of tokens when APIs return complete objects. Processing all of this and directly orchestrating multiple tool invocations from the AI becomes costly, both in terms of tokens and milliseconds.&nbsp;</p>



<p><strong>Agility</strong>: The pace of AI is unprecedented. The technology and techniques are progressing furiously. Just as interesting to me is that the freeform nature of AI makes it possible to deliver new functionality faster than ever before: most users wouldn’t tolerate a mobile app that changed every day, but continuous improvement of an AI agent is nothing but good news. So an AI stack needs to accommodate and facilitate a tempo we’ve never seen before in software development. This requirement rules out strategies that aren’t aligned to the modern platform engineering discipline of self-service tools and workflows.</p>

<p>What these requirements point to is the need for an abstraction layer between the AI and APIs. This <a href="https://www.apollographql.com/guides/api-orchestration">orchestration layer</a> exposes a set of MCP tools, where each tool provides a specific capability backed by some number of orchestrated API calls. The AI&#8217;s job is to reason about which MCP tools to invoke; the orchestration layer’s job is deterministic, efficient execution and policy enforcement.</p>



<p>GraphQL is an ideal foundation of this orchestration layer.</p>



<ul class="wp-block-list">
<li>It’s declarative: MCP tools are defined in terms of schema and queries, rather than code.</li>



<li>It’s performant: one GraphQL query can traverse your entire graph, gathering exactly what&#8217;s needed (and nothing that’s not) in an optimized way.</li>



<li>It’s self-documenting: LLMs can reason about the meaning of the graph and its objects.</li>



<li>It&#8217;s standards-based: a mature ecosystem with proven scalability.</li>



<li>It’s self-service: on a GraphQL-based platform like Apollo, everyone with access to the graph can wire up MCP tools with the appropriate level of governance.</li>
</ul>



<p>The characteristics of GraphQL align perfectly with what AI needs to access APIs: a clean, understandable interface to AI while handling the messy reality of existing systems and services. </p>



<p>Consider the earlier example of retrieving purchase history with shipping updates. A GraphQL query defines an MCP tool that the AI system can use. Under the hood, that query orchestrates multiple API calls into the order, shipping and loyalty systems and enforces the necessary policy check. That query can be authored and deployed by anyone on the platform, with the support of design and governance tools provided by the graph platform.</p>



<p>The challenges an abstraction layer solves may seem like tomorrow’s problems when just getting started with MCP. It’s always worth planning for success, but a good declarative architecture also saves time and effort in the earliest stages of development. A GraphQL-based approach avoids having to build, debug and deploy custom MCP servers. Apollo Connectors let you bring REST APIs to GraphQL (and now MCP) without any modification. And the benefits of having a semantic API layer are truly remarkable – watching an LLM traverse a large GraphQL schema as it builds a new query is an exciting, eye-opening moment.</p>

<p>The Apollo MCP Server represents our continued investment in making GraphQL the best way to build modern API infrastructure. We&#8217;ve spent years developing tools that help teams build, manage, and scale GraphQL – from <a href="https://www.apollographql.com/docs/react">Apollo Client</a> to <a href="https://www.apollographql.com/federation">Apollo Federation</a> to our most recent innovation, <a href="https://www.apollographql.com/graphos/apollo-connectors">Apollo Connectors</a>. Now we&#8217;re extending that toolkit to address AI integration.</p>



<p>By implementing MCP for GraphQL, we&#8217;re making it simple to connect AI to your existing graph. If you&#8217;re already using Apollo, this fits naturally into your stack. If you&#8217;re new to GraphQL, the MCP server provides a compelling entry point that solves immediate AI challenges while setting you up for future growth, all on top of the APIs you already have.</p>



<p>We believe the architectural patterns emerging around AI – the need for precision, policy, efficiency, and agility – align perfectly with what GraphQL was designed to do. This MCP server is our way of helping teams realize those benefits.</p>



<p>As you explore connecting AI to your services, consider not just immediate integration but your longer-term strategy. The architectural decisions you make today will determine how quickly and safely you can evolve AI capabilities tomorrow.</p>

<p>The runtime plane contains the GraphOS Router (Router) and Apollo Server.&nbsp; These components fulfill GraphQL query requests for both single-server graphs and federated supergraph deployments.&nbsp; For example, in a federated use case, clients send queries to the Router, which intelligently determines which back-end subgraphs contain the necessary data, orchestrates the data exchange, and returns precisely what the client requested.</p>



<p>GraphOS is a complete API orchestration solution that enables you to:&nbsp;</p>



<ul class="wp-block-list">
<li>Filter and transform data&nbsp;<br></li>



<li>Execute operations synchronously and in parallel<br></li>



<li>Manage authentication and authorization<br></li>

<p>The free plan replaced the enterprise trial plan that was limited to 90 days. This free plan has no time restrictions, making it easy to get started with GraphQL and prototype your next project.&nbsp;</p>



<p>It also offers access to Apollo Connectors, which integrates REST API data into a graph without writing complex procedural code. The free plan includes the same functionalities as the enterprise plan, with the following limitations:</p>



<ul class="wp-block-list">
<li>Self-hosted routers are rate-limited to 60 requests per minute<br></li>



<li>Organizations are limited to 3 team members<br></li>



<li>Insights, checks, and traces for graphs of all types (not just those using GraphOS Router), with data retention limited to one day</li>
</ul>



<p>Support is available through the <a href="https://community.apollographql.com/">Apollo Community</a>.</p>



<p>The free plan is ideal for personal projects and exploring GraphOS, providing all the essentials to learn, experiment, and create at no cost. When your API orchestration needs expand, Apollo’s paid plans immediately remove the free plan&#8217;s rate limits, allowing you to scale your workload to any level of request volume.&nbsp; Depending on your paid plan, you may also use features such as:</p>



<ul class="wp-block-list">
<li><strong>Single Sign-On (SSO)</strong> support<br></li>



<li><strong>GraphOS Router extensibility</strong>, such as external coprocessors<br></li>



<li><strong>Advanced collaboration tools</strong>, such as schema proposals or configurable linting<br></li>



<li>Comprehensive <strong>Audit History</strong></li>
</ul>

What’s New in GraphOS: Apollo Winter ’25 Release – Apollo Connectors, Native Query Planner, Improved Tools, and More!


<p>Today we are releasing <a href="https://www.apollographql.com/graphos/apollo-connectors">Apollo Connectors</a>, a major update that brings our declarative, graph-based orchestration technology to teams using REST APIs.</p>



<p>Modern applications integrate dozens or even hundreds of different APIs. The task is significant. These APIs must be called in a precise manner and sequence. API calls need to be chained together, feeding the output of one into the next. In some cases, it’s desirable to parallelize them for better performance. Synchronous services can be made async, and vice versa. Almost universally, it is necessary to filter, transform, and reformat the responses, as they are rarely an exact match for the needs of an application. Teams must properly handle errors and timeouts, not to mention authentication and authorization.</p>



<p>We can give a name to these tasks: API orchestration.</p>



<p>API orchestration accounts for a significant fraction of the total cost of implementing software. It shows up everywhere: application teams shipping roadmap items, companies migrating off of legacy software systems or onto modern microservice architectures, anyone acquiring products and integrating them together, and in every agentic AI project – the last of these especially top of mind now for many. And because orchestration requirements tend to be unique to each individual application or use case, teams end up accumulating a mountain of code dedicated to orchestration.</p>



<p>In the vast majority of cases, API orchestration is implemented procedurally, as code. This is the world of backends-for-frontends, integration APIs, and SDKs autogenerated from service catalogs. Sometimes the code is implemented as a separate tier, as in the BFF pattern. Other times, it lurks inside applications or services. No matter where it lives, this code is expensive to write and annoying to maintain. It holds API-rich companies back from shipping great products and getting the most value from their API investments.</p>



<h3 class="wp-block-heading"><a href="#graphql-is-graph-based-api-orchestration" aria-hidden="true" class="aal_anchor" id="graphql-is-graph-based-api-orchestration"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>GraphQL is graph-based API orchestration</h3>



<p>What we’ve known all along is that GraphQL is really a technology for API orchestration. GraphQL federation, which we developed in collaboration with many of the teams using GraphQL at large scales, allows developers to write GraphQL queries that get executed as an automatically planned sequence of individual API calls. The heart of what makes this possible is an advanced runtime, the <a href="https://www.apollographql.com/graphos-router">Apollo Router</a>, that provides connection management, rate limits, error handling, API call chaining and more, all made available through GraphQL schemas and operations.</p>



<p>Most of the API orchestration tasks I listed above? They’re built right into the Apollo Router with our implementation of <a href="https://www.apollographql.com/federation">GraphQL federation</a>. Apollo developers don’t write procedural code to cache API responses, enforce authentication policies, filter results, or join across APIs. To give one example of how much power comes with this, you can mark part of a query as “deferrable” which instructs the query planner to break the query into a synchronous portion and an async portion to be delivered later – typically data coming from slow APIs that you can’t allow to delay app interactivity or a screen render. Six characters and a couple of braces replace what would have been a significant amount of procedural code to write, test, and maintain.</p>



<p>GraphQL federation has been a huge success. It now powers many of the largest online retailers, media properties, traditional banks, and fintech startups. It’s probably inside your television and will almost certainly be in your next car. Companies that adopt this architecture are able to ship new products in a fraction of the time it used to take and with far less development risk.</p>



<h3 class="wp-block-heading"><a href="#bringing-graphql-to-everyone" aria-hidden="true" class="aal_anchor" id="bringing-graphql-to-everyone"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Bringing GraphQL to everyone</h3>



<p>There’s one hitch, though. To use graph-based API orchestration, you needed GraphQL APIs – either by adding GraphQL to existing services or by creating new GraphQL-specific services (what GraphQL federation developers call “subgraph servers”). This requirement was a significant up-front price of admission to the benefits of graph-based orchestration. And hearing customer after customer tell us about the REST APIs they wanted to bring to the graph led us to a key insight, which is that the responses from these APIs are awfully close to the entity objects that make up a federated GraphQL schema. All that’s really necessary is a language for describing the relationship between them.</p>



<p>And that leads us to today’s news: we’re making <a href="https://www.apollographql.com/graphos/apollo-connectors">Apollo Connectors</a> for REST APIs generally available, which lets you define a GraphQL schema in terms of the REST APIs you have and orchestrate calls to those APIs with just a few lines of configuration. </p>



<p>Connectors are meant to work with real-world APIs: they include functions you can use to restructure and transform API responses as needed and support the usual patterns for headers, auth credentials, and so on. And it’s just federated GraphQL under the hood, so you can use all the usual federation features and mix and match any combination of REST and GraphQL together. You can read much more technical detail about how Apollo Connectors work in our <a href="https://www.apollographql.com/blog/our-journey-to-apollo-connectors">engineering blog</a>, the <a href="https://www.apollographql.com/docs/graphos/schema-design/connectors">documentation</a>, or just give it a try with your own APIs. Everything you need is included in our free tier of GraphOS and you can be orchestrating APIs in well under an hour.<br>Since we <a href="https://www.apollographql.com/events/exploring-apollo-s-new-products-a-deep-dive">previewed Apollo Connectors</a> at GraphQL Summit in October we’ve worked with many of you to improve every aspect of their tooling and functionality. Early results are promising: you can read about how the team at <a href="https://www.apollographql.com/customers/cox-automotive">Cox Automotive </a>used Apollo Connectors to add a particularly important API to their graph in just days, saving nearly a year of otherwise planned development work. We’re looking forward to hearing about your experience.</p>

<p>Declarative architectures define the modern, cloud-native stack. Containerization for packaging software. React for packaging UI components. It should be no different for APIs.  Apollo Connectors allows developers to describe the data model they want, and let Apollo&#8217;s graph-based API orchestration infrastructure figure out how to do it.</p>



<p>We believe declarative, graph-based orchestration is going to replace procedural orchestration code. We’re excited to see GraphQL become the standard that all developers can reach for and we’re committed to working with everyone interested to make that happen. And we can’t wait to see what you build with it.</p>

REST API Orchestration With GraphQL

Our Journey to Apollo Connectors


<p>We&#8217;re announcing an important update: starting with the 1.60 release of <a href="https://www.apollographql.com/graphos-router">Apollo GraphOS Router</a> and Apollo Router Core coming in the next few weeks, <a href="https://www.apollographql.com/federation">Apollo Federation</a> 1.0 supergraphs will no longer be supported. This update accompanies the introduction of a <a href="https://www.apollographql.com/docs/graphos/routing/query-planning/native-query-planner">new native query planner</a> in these Apollo Router versions, marking a significant advancement in our technology. <a href="https://www.apollographql.com/docs/graphos/reference/migration/to-federation-version-2">Upgrading to Apollo Federation 2.0</a> is essential to leverage these improvements fully, and as Federation and Apollo Router are mission-critical infrastructure for your API workloads, we are here to guide you through every step of this transition to confidently operating your GraphQL platform.</p>



<p><strong>Understanding the importance of upgrading</strong></p>



<p>The next Apollo Router versions, 1.60 and beyond, include a new native query planner with significant performance enhancements. Our extensive testing of over 620 million operations showed a median 10x improvement in query planning time, a 2.9x reduction in CPU utilization, and a 2.2x reduction in memory consumption. Designed specifically for Federation 2.0 supergraphs, this new query planner simplifies maintenance and enhances security by eliminating dependencies, including the need for a JavaScript execution engine within the Apollo Router process.</p>



<p><strong>Timeline and planning</strong></p>



<p>Federation 1.0 supergraphs have been marked as deprecated in our <a href="https://www.apollographql.com/graphos/studio">GraphOS Studio</a> UI and users have not been able to create them since Q3 2023. With the upcoming new Apollo Router versions, support for Federation 1.0 supergraphs will end across all Apollo products, including Apollo Gateway. We strongly recommend you upgrade to Apollo Router and Federation 2.0 to ensure continued compatibility with our latest innovations.</p>



<p>If you are still operating your GraphQL deployment without having yet migrated to Federation 2.0, upgrading to the new query planner in Apollo Router 1.60 and beyond will introduce a breaking change.&nbsp;</p>



<p>Migration to Federation 2.0 is simple and focuses on the composition layer, without requiring changes to existing subgraphs in most cases. You only need to compose a supergraph with Federation 2.0 and typically your subgraphs can continue using Federation 1.0 until they need 2.0 features. Our<a href="https://www.apollographql.com/docs/graphos/reference/migration/to-federation-version-2"> migration guide</a> details how you can update just your Federation composition step to compile a compatible supergraph.</p>



<p><strong>Available resources and ongoing support</strong></p>



<p>We recognize that transitioning from Federation 1.0 to Federation 2.0 is a significant step for some of our users. This decision reflects our commitment to eliminating the complexities of outdated technology and ensuring our offerings meet the evolving needs of modern API infrastructures. We are dedicated to transparent communication and improving our deprecation processes to help maintain the robustness, efficiency, and security of your systems.&nbsp;</p>



<p>Apollo values your partnership and trust as we continue to innovate. We are here to support you through this transition to keep your API infrastructure powerful and future-proof. For additional support, please visit our <a href="https://community.apollographql.com/t/migrate-apollo-federation-1-0-supergraphs-to-apollo-federation-2-0/8125">Apollo Community</a> or, for GraphOS users, contact our Technical Support team at <a href="mailto:support@apollographql.com">support@apollographql.com</a>. </p>

Migrate Apollo Federation 1.0 Supergraphs to Apollo Federation 2.0


<p>Writing resolvers for REST APIs has been a rite of passage for developers working with GraphQL, but what if there were an easier way? Meet Apollo Connectors.&nbsp;&nbsp;</p>



<p>As shown in Figure 1, Apollo Connectors mitigate the need to write code that connects to and returns data from REST APIs, reducing code surface area and time so you can focus on the business problem you&#8217;re trying to solve.</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXdJZU6oZN7MiGs9r1tQQXZkwJJpcuPFikCrKor3lk6x3MroNldHwChst6pbHyV0h2d8fx0bdhmW7xxntWRZCNWhxOe3ZrMe-lt0P1_MZQ16jxNuOmPkQdayuZT_XW9cF_69YpmiEA?key=Tfq51hg4_0CBkUiIKxkXplEo" alt=""/></figure>



<p><em>Figure 1: Data flow showing Apollo Connector for REST APIs</em></p>



<p>In this article, we will walk through a React client web application that leverages the Apollo GraphQL client to call a public <a href="https://currencyapi.com/">CurrencyAPI</a> web service using the REST API Apollo Connector for REST APIs.&nbsp; A screenshot of the UI is seen in the following figure:&nbsp;&nbsp;</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXdmYwlhbO07vkGGfTIugVC2usLpczle-KJMiJoGsGgE53FYx4zzzo3TFsFiMJ5InCSTzJ7HA7cSxtF9HRXJLQ7j6zhZ1jatfDn1WGDFQ2sY-ixRi7Fmpz-HNH2TQPQiOOmat7an?key=Tfq51hg4_0CBkUiIKxkXplEo" alt=""/></figure>



<p><em>Figure 2: Screenshot of the Currency Converter</em></p>



<p>Under the covers, the React app uses the GraphQL Client as usual and issues the query statement.&nbsp; There are no changes there.&nbsp; On the backend, you simply define the GraphQL schema file and that’s it. There is no need to create resolvers to fetch the data from the REST API.&nbsp; In the following sections, you will learn how to set up and configure the Apollo Connector for REST APIs.</p>

<p>A note about <code>router-config.yaml</code>:&nbsp; In this example, we are launching a react client on the same machine as Rover.&nbsp; Since these are operating on different ports, the client on localhost:4000 and Rover on localhost:3000, the server needs to address CORS (Cross origin resource sharing).&nbsp; To do this, we added the following configuration to the <code>router-config.yaml </code>file:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-yaml">cors:

<p>Navigate to the <strong>client</strong> folder and issue:</p>



<p><code>npm install</code></p>



<p>Then</p>



<p><code>npm start</code></p>



<p>Once launched, a web browser will open to localhost:3000 and display the UI shown in Figure 2.</p>



<p>Enter any value into the amount and select your favorite base and desired currency.&nbsp; Press Convert to see the most current amount in your desired currency.</p>



<p>Let’s take a look at what is happening under the covers.&nbsp; First let’s look at the client code, specifically the <code>convert.js</code> file within the <strong>src/components </strong>folder.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-typescript">// GraphQL query to fetch currencyList and listExchangeRate

<p>Our simple example has two queries <code>currencyList</code><strong>,</strong> which returns the complete list of symbols and names for the currency, and <code>listExchangeRate</code><strong>,</strong> which returns the current rate for each symbol.&nbsp; These data are used to populate the drop-downs in the UI.&nbsp; When using Apollo Connectors, the client does not need to make any changes.&nbsp; It is business as usual for your front-end folks.&nbsp; The real magic is in the back end.</p>

<p>Open the <code>currency.graphql</code> file.&nbsp; This file contains the configuration for the REST Apollo Connector.&nbsp;&nbsp;</p>

    )
}

type Currency {
   symbol: String
   name: String
}

type ExchangeRate {
   symbol: String
   rate: Float
}</code></pre>



<p>This is all that is needed for your Apollo Server to connect to a REST API, no extra resolver code!&nbsp; Looking at the GraphQL query, you’ll see an <code>@link</code> statement referencing Apollo Connector.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">@link(
  url: &quot;https://specs.apollo.dev/connect/v0.1&quot;
  import: [&quot;@source&quot;, &quot;@connect&quot;]
)</code></pre>



<p>Here, we are importing the <code>@source</code> and <code>@connect</code> directives.&nbsp; The <code>@connect</code> requires additional configuration parameters such as the details about the HTTP request, any headers, and a parameter called “selection” which filters the data from the REST API results.&nbsp; Here is the <code>currencyList</code> field in our example:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">  &quot;A list of currencies&quot;
  currencyList: [Currency]
    @connect(
      source: &quot;v1&quot;
      http: { GET: &quot;/currencies&quot; }
      selection: &quot;&quot;&quot;
        data-&gt;entries {
          symbol: key
          name: value.name
        }
      &quot;&quot;&quot;
    )</code></pre>



<p>In this query, the Apollo Connector will use the base url defined in the <code>@link</code> and append the string defined as part of the HTTP request type in this case is GET.&nbsp; Since our currencyAPI endpoint requires an authentication header, we add the <strong>headers</strong> field and add a key-value pair referencing the API Key and value we defined earlier in the <code>router-config.yaml </code>file.&nbsp; Next, we need to tell the connector what data to extract from the API results.&nbsp; We define this in the <strong>selection</strong> parameter.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-perl">data-&gt;entries {
  symbol: key
  name: value.name
}</code></pre>



<p>For reference, the data that returns from the CurrencyAPI is similar to the following:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-json">{
  &quot;data&quot;: {
    &quot;AED&quot;: {
      &quot;symbol&quot;: &quot;AED&quot;,
      &quot;name&quot;: &quot;United Arab Emirates Dirham&quot;,
      &quot;symbol_native&quot;: &quot;د.إ&quot;,
      &quot;decimal_digits&quot;: 2,
      &quot;rounding&quot;: 0,
      &quot;code&quot;: &quot;AED&quot;,
      &quot;name_plural&quot;: &quot;UAE dirhams&quot;,
      &quot;type&quot;: &quot;fiat&quot;,
      &quot;countries&quot;: [
        &quot;AE&quot;
      ]
    },
    ...
  }
}</code></pre>



<p>For our client we want to return just the symbol and name of each of the currencies.&nbsp; Since our return result has all our data under the “data” field, we start with data and iterate through each subdocument using the <strong>entities</strong> keyword.&nbsp; For each of these <strong>entities,</strong> we return the key, which in this example result is “AED” and add that value to a “symbol” field.&nbsp; We give the field “name” the value of the name field in the result. For a complete discussion and more examples of selection parameters, see the <a href="https://www.apollographql.com/docs/graphos/schema-design/connectors/selection">online documentation</a>.</p>

<p>Building resolvers for REST APIs can be a complex yet essential task for developers working with GraphQL. However, Apollo Connectors now provide a simpler, more efficient way to integrate REST APIs into your GraphQL schema, eliminating the need for custom resolver code. In this article, you learned how to setup and configure an Apollo Connector for REST APIs that query data from the CurencyAPI public API endpoint.&nbsp; Apollo Connectors is currently in preview, for more information, check out the <a href="https://www.apollographql.com/graphos/apollo-connectors">Apollo Connectors</a> website.</p>

Effortless Data Fetching: Introducing Apollo Connectors for REST APIs


<p>Apollo Connectors make it easier than ever to create a GraphQL API leveraging non-GraphQL services. Developers can use a declarative syntax, right in their schema files, to connect GraphQL fields to HTTP APIs. GraphOS Router uses that information to talk <em>directly</em> to the API, no subgraph needed.</p>

<p>Before today, when developers wanted to add a REST service to their federated GraphQL API, they had to take several steps:</p>



<ol class="wp-block-list">
<li>Identify a programming language and a Federation-compatible GraphQL framework</li>



<li>Deploy a new subgraph service, including monitoring, auto-scaling, and load-balancing, which will sit in between the router and the REST API</li>



<li>For each change to the REST API:
<ol class="wp-block-list">
<li>Design the subgraph schema for the underlying REST data</li>



<li>Write bindings to the REST API in the chosen programming language</li>



<li>Write resolvers that leverage those bindings</li>



<li>Deploy the subgraph service</li>



<li>Compose and publish the schema to update the router</li>
</ol>
</li>
</ol>



<p>Apollo Connectors eliminate the need for the intermediate service, saving developer time and infrastructure cost. With connectors, each iteration is reduced to:</p>



<ol class="wp-block-list">
<li>Design the subgraph schema for the underlying REST data</li>



<li>Compose and publish the schema to update the router</li>
</ol>



<p>The router then speaks directly to the REST APIs:</p>

<p>Apollo Connectors are designed with a singular goal in mind: make it as easy as possible for developers to build high-quality GraphQL APIs. Every aspect was built from the ground up to achieve this goal, starting with the declarative syntax:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">type Query {
 post(id: ID!): Post
   @connect(
     source: &quot;rest_api_v1&quot;
     http: { GET: &quot;/posts/{$args.id}&quot; }
     selection: &quot;&quot;&quot;
       id
title
body
author: { id: userId }
     &quot;&quot;&quot;
   )
}</code></pre>



<p>Data sources are connected right in your schema, so there&#8217;s no need to hop back and forth between multiple files. The selection format, for transforming the data, is designed to feel like the GraphQL query language to reduce context switching. It&#8217;s also designed to provide as much feedback as possible early in the development lifecycle, especially when combined with our <a href="http://go.apollo.dev/connectors/guides#visual-studio-code">Visual Studio Code extension</a>. No more catching typos after deploy:</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXfTnKYrGuW1QQgne9IzJQFlLYxcC_tYJD8KOGK4MV2o1jlSiV-tmWWYyR-Mr42H0bQoz0TyKM1nTW8Rd3xymb7s2JRS3JB881hhNPmuSLhho9IfACWABG7xI917Pk6cskl45msWuHK9AdjwR8_lanBEat0?key=X-2ujg-cWaXZiwKXT52_aQ" alt=""/><figcaption class="wp-element-caption">Apollo&#8217;s Visual Studio Code extension underlines errors in your Connectors definition</figcaption></figure>



<p>Our focus on developers extends through the testing phase, with powerful new debugging tools built into <a href="https://www.apollographql.com/docs/graphos/explorer/sandbox/">Apollo Sandbox</a>:</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXcuYoRXVO2LnwxaISPX-Cn_aGE_-Hz5J9W_rmxODLNyECou0Q3MLijxEYKRiMxnvCiQnqLSRqTvTaMPByLdVx-A2xLCoZpHlW8YirW0gZA8m0fRnUmmziCfeJoSbwLuCOjfM93XRz6yhXKpl4U69ydOs1O1?key=X-2ujg-cWaXZiwKXT52_aQ" alt=""/></figure>

<p>With the release of Apollo Kotlin 4, we&#8217;ve achieved a significant milestone where our core APIs—including code generation, parsers, and interceptors—are now stable. This stability means we don’t anticipate any major overhauls like the transition from version 2 to 3, though the landscape of Kotlin and GraphQL continues to evolve rapidly. Developments such as <a href="https://youtrack.jetbrains.com/issue/KT-68296">union types for errors</a> or <a href="https://github.com/graphql/nullability-wg/discussions/58">semantic nullability schemas</a> may necessitate breaking changes in the future.</p>



<p>Looking ahead, our goal is to roll out smaller, more frequent updates, including major versions. This approach will keep the core APIs consistent, enabling us to introduce new features and adapt more swiftly to changes in the environment. To facilitate this, we’ve updated the package name from <code>com.apollographql.apollo3</code> to <code>com.apollographql.apollo</code>.<br><br>With Apollo Kotlin 4, we are also introducing an evolution policy. This policy will steer the development of future versions and ensure that we provide clear deprecation notices, helping you to transition smoothly and confidently.</p>



<h2 class="wp-block-heading"><a href="#multiplatform-graphql-parser" aria-hidden="true" class="aal_anchor" id="multiplatform-graphql-parser"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Multiplatform GraphQL parser</h2>



<p>Previously, Apollo Kotlin relied on<a href="https://github.com/graphql/graphql-js" data-type="link" data-id="https://github.com/graphql/graphql-js"> <code>graphql-js</code></a> for parsing GraphQL documents. In version 2, we transitioned to using <a href="https://www.antlr.org/">Antlr</a> to generate parsers from <code>.g4</code> grammars.</p>



<p>With Apollo Kotlin 4, we’ve taken a significant leap forward by developing our <a href="https://github.com/apollographql/apollo-kotlin/pull/5047">own recursive descent</a> parser.</p>



<p>The new parser not only performs up to <a href="https://github.com/apollographql/apollo-kotlin/pull/5047#issue-1780385717">twice </a>as fast as the previous Antlr-based parser in certain scenarios, but it’s also entirely written in Kotlin, ensuring full multiplatform support. This means you can seamlessly integrate it into your Kotlin multiplatform projects just like any other KMP dependency.</p>



<p>Here’s how you can add the new parser to your project:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-kotlin">kotlin {
  sourceSets {
    getByName(&quot;commonMain&quot;) {
      dependencies {
        implementation(&quot;com.apollographql.apollo:apollo-ast&quot;)
      }
    }
  }
}</code></pre>



<p>And here’s how to utilize it at runtime:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-kotlin">  // Parse a document
  val document = &quot;query { hello }&quot;.toGQLDocument()

  // transform/inspect it
  // And serialize it again
  println(document.toUtf8())</code></pre>



<h2 class="wp-block-heading"><a href="#introducing-wasmjs-support" aria-hidden="true" class="aal_anchor" id="introducing-wasmjs-support"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Introducing WasmJs support</h2>



<p>Apollo Kotlin 4 now includes support for the WasmJs target, expanding your capabilities to use the generated models and <code>apollo-runtime</code> in a Wasm application. Experience this new feature firsthand by trying out the Confetti wasm demo at <a href="https://wasm.confetti-app.dev/">https://wasm.confetti-app.dev/</a> (<a href="https://github.com/joreilly/Confetti">GitHub</a>).</p>

<p>In GraphQL, <a href="https://graphql.org/learn/best-practices/#nullability">fields are traditionally nullable by default</a>. However, the standards set in 2015 don’t always align with the needs of 2024, especially as <a href="https://github.com/graphql/nullability-wg/">the GraphQL community seeks to enhance </a>type safety for languages like TypeScript, Swift, and Kotlin.</p>



<p>Apollo Kotlin 4 introduces two experimental directives, <code>@semanticNonNull</code> and <code>@catch</code>, designed to simplify interactions with nullable fields.</p>



<p>The <code>@semanticNonNull</code> directive is a server-side directive, indicating that a field is guaranteed to be non-null unless an error happens. This directive can be incorporated into your <code>.graphqls</code> schema extensions, enhancing the clarity and reliability of your data models:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-kotlin"># name is never null unless an error happens
extend type User @semanticNonNullField(name: &quot;name&quot;)</code></pre>



<p>On the code generation front, Apollo Kotlin recognizes <code>@semanticNonNullField</code> and accordingly generates non-null Kotlin properties, ensuring that your application code remains type-safe and concise.</p>



<p>Additionally, the <code>@catch</code> directive is a client-side directive for opting into specific error handling strategies during operations. By using <code>@catch</code> in your <code>.graphql</code> operations, you can manage how errors are handled directly within the data context—whether by mapping errors to <code>null</code>, re-throwing them, or using another method:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-kotlin">query GetUser {
  user {
    # map name to FieldResult&lt;String?&gt; instead of stopping parsing
    name @catch(to: RESULT)
  }
}</code></pre>



<p>For a deeper understanding of these enhancements and their implications on your projects, please refer to our detailed <a href="https://www.apollographql.com/docs/kotlin/v4/advanced/nullability#handle-errors-and-receive-partial-data-with-catch">nullability documentation page</a>.</p>

<p>Beyond the updates already discussed, Apollo Kotlin 4 introduces several exciting features including support for<a href="https://github.com/graphql/graphql-spec/pull/825"> <code>@oneOf</code></a>, new WebSockets APIs, new low-level Apollo compiler plugin APIs, and new Gradle APIs. For a detailed list of all the enhancements, make sure to read the full changelog.</p>



<p>One significant area poised for further development is the normalized cache, which continues to present challenges. While Apollo Kotlin 3 introduced <a href="https://www.apollographql.com/docs/kotlin/caching/declarative-ids/">&nbsp;<code>@typePolicy</code> and <code>@fieldPolicy</code> for declarative ids</a>, certain scenarios still demand the use of complex programmatic APIs.</p>



<p>Additionally, issues such as garbage collection and invalidation remain unresolved. We aim to address these in version 5.</p>



<p>With the modularization of Apollo Kotlin development has shifted to <a href="https://github.com/apollographql/apollo-kotlin-normalized-cache-incubating/">a separate repository</a>, enabling more agile iteration and improvement.<br>For the latest updates and future plans, please refer to <a href="https://github.com/apollographql/apollo-kotlin/blob/main/ROADMAP.md">the ROADMAP</a> document on what is being worked on.</p>

Apollo Kotlin 4 is now available


<p>On, June 12, 2024, we hosted our <a href="https://www.apollographql.com/events/apollo-graphos-summer-update-operational-excellence-for-graphql-federation">GraphOS summer launch event</a>, where we announced new features designed to improve the performance and operational excellence of GraphQL platforms. These new capabilities improve how API platform teams implement and optimize GraphQL federation, providing faster baseline performance and greater control over API request execution in a supergraph.</p>



<h2 class="wp-block-heading"><a href="#graphql-federation-usage-on-the-rise" aria-hidden="true" class="aal_anchor" id="graphql-federation-usage-on-the-rise"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>GraphQL Federation: Usage on the rise</h2>



<p>GraphQL adoption in the enterprise is at an inflection point, driven by the proliferation of federated GraphQL architectures – a pattern originally introduced by Apollo GraphQL in 2019 with the launch of Apollo Federation and <a href="https://www.apollographql.com/graphos">GraphOS</a>. In a <a href="https://www.apollographql.com/resources/gartner-when-to-use-graphql-to-accelerate-api-delivery">recent report</a>, Gartner® predicts that 30% of enterprises using GraphQL will utilize GraphQL federation by 2027, up from less than 5% in 2024. Apollo believes this trend suggests the number of enterprises using GraphQL federation as their API access layer will increase by 12x.</p>



<p>Apollo Federation is a specification for modularly and declaratively mapping existing application services into a unified GraphQL API access layer, known as a supergraph. This architecture empowers platform engineering teams to provide client applications with self-serve access to services through a single GraphQL endpoint, facilitating the rapid evolution of complex end-user experiences. By decoupling backend development from frontend complexity, teams can independently manage and contribute services to the supergraph via subgraphs, representing core business entities such as Product, User, or Cart.</p>



<p>In our summer launch, we focused on the Operational Excellence pillar of the <a href="https://saf.apollographql.com/">Supergraph Architecture Framework</a>. The <a href="https://www.apollographql.com/docs/graphos/enterprise/supergraph-architecture-framework/operational-excellence">Operational Excellence pillar</a> focuses on empowering subgraph and stewardship teams. A well-architected graph isn&#8217;t only technically excellent—it&#8217;s also operationally excellent. Processes and tools should be in place to ensure that the supergraph is easy to use, understand, and maintain.

Embracing The Future And Welcoming Our New CMO


<p><em>Caching, Native Cost Calculation and Limiting, and Telemetry Capabilities Revolutionize API Management and Streamline Building Cross-Platform Digital Application Experiences</em></p>



<p>Today at PlatformCon, <a href="https://apollographql.com">Apollo GraphQL</a>, the creator of GraphQL federation, announced new features in <a href="https://www.apollographql.com/graphos/">Apollo GraphOS</a> are now generally available to better leverage GraphQL’s developer productivity and performance benefits at any scale. This release provides API platform teams with visibility, usability, and performance benefits for GraphQL federation, enabling the engineering teams they serve to maximize the value of their APIs across their business.</p>



<p>As the leading GraphQL federation platform, GraphOS provides an abstraction layer for API complexity, enabling product engineering teams to rapidly build and iterate features based on customer demand. <a href="https://www.apollographql.com/resources/gartner-when-to-use-graphql-to-accelerate-api-delivery">Gartner® predicts that </a>30% of enterprises using GraphQL will utilize GraphQL federation by 2027, up from less than 5% in 2024.<sup>1 </sup>Apollo believes this trend suggests the number of enterprises using GraphQL federation as their API access layer will increase by 12x. GraphOS provides everything enterprise teams need to deliver GraphQL federation at any scale.&nbsp;</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p>“GraphQL federation removes the friction between the frontend and backend that we see in distributed architectures,” said Matt DeBergalis, Chief Technology Officer and co-founder at Apollo GraphQL. “This latest GraphOS release enables API platform teams to operationalize GraphQL federation’s benefits faster, so they can focus less on building custom tooling and more on their customers’ needs.”</p>
</blockquote>



<p>This latest GraphOS release includes significant improvements around observability, usability, and performance, enabling API platform teams to operate GraphQL federation more easily than ever before.&nbsp; “At enterprise-scale, every millisecond of latency in your consumer’s digital experiences impacts the bottom line,” said Rob Brazier, VP of Product at Apollo GraphQL. “With this release of Apollo GraphOS, we’ve made it even easier for API platform teams to observe and optimize the performance of federated graphs.”&nbsp;</p>



<p><strong>Apollo’s latest release provides operational excellence for GraphQL federation</strong></p>



<p>GraphQL federation is becoming a de facto architecture for platform engineering teams to simplify API governance across distributed architectures. Client teams can fetch all the data they need from a single endpoint, and this paradigm enables API platform teams to enforce better governance, provide better visibility into service usage, as well as use standardized tools for performance. GraphOS provides a complete solution for delivering GraphQL federation at any scale:</p>



<div class="wp-block-group is-vertical is-layout-flex wp-container-core-group-is-layout-2 wp-block-group-is-layout-flex">
<ul class="wp-block-list">
<li><strong>Better application performance</strong> – Apollo introduces an improved and simplified form of API caching built for GraphQL federation. GraphOS’s caching layer spans any number of APIs and now, in public preview, supports entity caching. Entities are object types that are composed from multiple GraphQL APIs and are the business objects or “nouns of every business.” API platform teams can store entities such as their inventory, products, or user records in a Redis data store. API platform teams can set how long these entities are cached in the data store, enabling API platform teams to significantly improve performance across an entire fleet of applications. &#8220;We&#8217;ve rolled out entity caching in production and are observing a decrease in median response time,&#8221; said Nimit Barochia, Senior Principal Software Engineer at Dow Jones. &#8220;The major improvement is how much less traffic we send to our subgraphs. Like a 8-10x decrease in some cases.&#8221;</li>
</ul>



<ul class="wp-block-list">
<li><strong>Cost control </strong>– API platform teams need a means to ensure that costly GraphQL operations don’t slow performance or create a denial of service. Platform teams need a means to limit cost of GraphQL operations processed by the GraphOS Router. Apollo is adding in public preview native cost calculation and limiting to GraphOS to make it easy for platform teams to centrally implement this, rather than relying on underlying services.</li>



<li><strong>Stronger support and improved performance</strong> – Micro-frontends provide a frontend architecture that refines performance and composability across mobile and web applications. To improve performance, micro-frontend UIs typically batch multiple client operations, issued close together, into a single API request. GraphOS is adding better support for these use cases, enabling GraphOS to handle batched requests from clients to a supergraph. It also further augments performance by ensuring that batches are kept intact when processed and passed on to the required subgraphs.</li>



<li><strong>Enhanced telemetry</strong> – API platform teams need both standardized and custom metrics to better optimize federated graphs for performance and business objectives. GraphOS now provides unparalleled visibility to debug and optimize federated graphs, enabling these teams to import these metrics into their Application Performance Monitoring tool of choice for better decision-making.&nbsp;</li>



<li><strong>Significant improvements to the GraphOS management plane</strong> – In Apollo Studio, schema checks and insights enable API teams to build, test, and ship changes to their federated graph with confidence. This release features significant UX improvements and better insights, enabling API teams to ship changes faster without introducing breaking changes to downstream clients.</li>
</ul>
</div>



<p><strong>Apollo customers to focus on innovation instead of API aggregation or orchestration</strong></p>



<p>AI is driving rapid innovation across industries, making the API layer critical for delivering competitive, personalized applications. Apollo aims to help API platform teams leverage GraphQL federation’s benefits across engineering organizations, empowering their teams to lead their organizations into the AI era.&nbsp;</p>

Apollo GraphQL Announces Major GraphOS Update, Enhancing Observability and Performance for Enterprise-Scale GraphQL Federation


<p>Apollo Client 3.10 has just been released, and we want to provide you with an overview of what&#8217;s new:</p>



<ul class="wp-block-list">
<li>Introducing new experimental schema-based testing utilities</li>



<li>New API: <code>client.watchFragment</code></li>



<li><code>createQueryPreloader</code> reaches &#8220;stable&#8221; status</li>
</ul>



<p>Let&#8217;s take a look:</p>



<h2 class="wp-block-heading"><a href="#introducing-new-experimental-schema-based-testing-utilities" aria-hidden="true" class="aal_anchor" id="introducing-new-experimental-schema-based-testing-utilities"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Introducing new experimental schema-based testing utilities</h2>



<p>In Apollo Client 3.10, we are introducing new schema-based testing utilities under the <code>@apollo/client/testing/experimental</code> import.</p>



<p>This adds two new tools:</p>



<p><strong><code>createTestSchema</code></strong> allows you to enhance a <code>GraphQLSchema</code> class with mock scalars and mock resolvers. </p>



<p>You can modify the resolvers inside your tests to simulate changing results.</p>



<p>This approach is an alternative to the current testing approach with <code>MockProvider</code>, allowing you to write tests similar to how you would implement your backend &#8211; applying skills you already have and can use in other situations.</p>



<p>You can then use this schema with <a href="https://mswjs.io/" data-type="link" data-id="https://mswjs.io/">Mock Service Worker</a> to simulate a GraphQL server, or you can use our new <strong><code>createSchemaFetch</code></strong> function to create a <code>fetch</code> function to be used inside of your tests.</p>



<p>Both of these approaches allow you to use your real link chain instead of a mocked one.</p>



<p>You can read more on this testing approach in <a href="https://github.com/apollographql/apollo-client/issues/11705" data-type="link" data-id="https://github.com/apollographql/apollo-client/issues/11705">the schema-driven testing RFC</a> and <a href="https://www.apollographql.com/docs/react/development-testing/schema-driven-testing" data-type="link" data-id="https://www.apollographql.com/docs/react/development-testing/schema-driven-testing">the documentation</a>.</p>



<h2 class="wp-block-heading"><a href="#new-api-client-watchfragment" aria-hidden="true" class="aal_anchor" id="new-api-client-watchfragment"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>New API: <code>client.watchFragment</code></h2>



<p>We also add a new function to the <code>ApolloClient</code> class: <code>watchFragment</code>.</p>



<p>This function enables the functionality of the <code>useFragment</code> hook to be used in Vanilla JavaScript or other frameworks. </p>



<p>A PR to add a <code>watchFragment</code> functionality to <code>apollo-angular</code> has already been opened, and more will follow soon!</p>



<h2 class="wp-block-heading"><a href="#createquerypreloader-reaches-stable-status" aria-hidden="true" class="aal_anchor" id="createquerypreloader-reaches-stable-status"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><code>createQueryPreloader</code> reaches &#8220;stable&#8221; status</h2>



<p>In Apollo Client 3.9, we introduced the <code>createQueryPreloader</code> API as &#8220;alpha&#8221;, and since we&#8217;ve heard your positive feedback, with 3.10, we&#8217;re releasing it as &#8220;stable.&#8221;</p>



<p><code>createQueryPreloader</code> is used to start a query outside of React (e.g. in a Router action) and then later attach to the generated <code>queryRef</code> with the <code>useReadQuery</code> hook.</p>



<p>You can read more about it in the <a href="https://www.apollographql.com/docs/react/data/suspense/#initiating-queries-outside-react" data-type="link" data-id="https://www.apollographql.com/docs/react/data/suspense/#initiating-queries-outside-react">documentation</a>.</p>


What’s new in Apollo Client 3.10


<p>In the realm of software development, evolution is not just desirable; it&#8217;s inevitable. Technologies advance, methodologies shift, and systems need to adapt to meet changing demands. In this ever-evolving landscape, Apollo Federation 2.7 introduces a groundbreaking feature: progressive <code>@override</code> ✨</p>



<p>Rolling out any change to a production subgraph, including field migration, risks degrading the performance of your graph. Progressive <code>@override</code> enables you to migrate any part of your graph to a new service and customize how traffic is gradually rolled over to the new service.</p>



<h2 class="wp-block-heading" id="Understanding-@override:-A-Primer"><a href="#understanding-override-a-primer" aria-hidden="true" class="aal_anchor" id="understanding-override-a-primer"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Understanding <code>@override</code>: A Primer</h2>



<p>Before delving into the nuances of progressive <code>@override</code>, let&#8217;s take a moment to revisit the concept of <code>@override</code>. <code>@override</code> provide a mechanism for migrating fields from one subgraph to another. By applying an <code>@override</code> directive to a specific field, traffic for that field is rerouted to the designated service, facilitating the breakdown of monolithic architectures or the migration of fields between subgraphs.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql"># Inventory subgraph
type Product @key(fields: &quot;id&quot;) {
  id: ID!
  inStock: Boolean! @override(from: &quot;Products&quot;)
}</code></pre>



<p>In the example above, we’re migrating the <code>Product.inStock</code> field from the <code>Products</code> subgraph to the <code>Inventory</code> subgraph. Rerouting all traffic from one subgraph to another all at once could overload the overriding subgraph.</p>



<h2 class="wp-block-heading" id="Override-only-a-portion-of-traffic"><a href="#override-only-a-portion-of-traffic" aria-hidden="true" class="aal_anchor" id="override-only-a-portion-of-traffic"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Override only a portion of traffic</h2>



<p>Anything that ships to production, ideally, has a gradual rollout with a certain percentage of traffic. This gives us the ability to roll back any bad deployments with a smaller impact in case everything is just broken (we’ve all been there 😅).</p>



<p>Progressive <code>@override</code> makes this simple for our Apollo Router to handle. Simply label your <code>@override</code> directive with the supported <code>percent(x)</code> syntax.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql"># Inventory subgraph
type Product @key(fields: &quot;id&quot;) {
  id: ID!
  inStock: Boolean! @override(from: &quot;Products&quot;, label: &quot;percent(1)&quot;)
}</code></pre>



<p>Now our router will begin routing approximately 1% of all traffic to our new Inventory subgraph for the <code>Product.inStock</code> field. When we want to ramp that up, we can simply update our schema and once we reach 100%, we can remove the <code>inStock</code> field from the original <code>Product</code> subgraph 🎉</p>

<p>It’s great that we can define a given percentage of traffic, but maybe we want to enable some items to bypass this percentage. You may want your beta application to always route to the new faster service 🏃</p>



<p>The router provides an interface for coprocessors and rhai scripts to resolve arbitrary labels. This means you can provide anything as the label and have the router interact with your external coprocessor to resolve the label. For an example implementation of a coprocessor that resolves labels using LaunchDarkly, see <a href="https://github.com/apollographql/router/tree/main/examples/coprocessor-override-launchdarkly/README.md">the example</a> in the router repo.</p>

<p>A common use case we see with progressive <code>@override</code> is breaking down a GraphQL monolith. Everyone starts their GraphQL adoption journey with a monolith and although that can take you far, there are challenges as the usage of the graph increases. Eventually there is a desire to break a service off of the monolith, whether it’s to address a performance issue or maybe to utilize a new 3rd party service.</p>



<p>The easiest way to evaluate breaking up the monolith is to start with a known view that has some meaningful value in the overall application. You’ll want to keep the shape of the operation the same for the client so that you can just use a new URL for that single view&#8217;s GraphQL query. Let’s take this screen as an example:</p>


<div class="wp-block-image">
<figure class="aligncenter size-full"><img loading="lazy" decoding="async" width="444" height="673" src="https://wp.apollographql.com/wp-content/uploads/2024/04/Screenshot-2024-04-08-at-10.08.19-AM-1.png" alt="" class="wp-image-23637" srcset="https://wp.apollographql.com/wp-content/uploads/2024/04/Screenshot-2024-04-08-at-10.08.19-AM-1.png 444w, https://wp.apollographql.com/wp-content/uploads/2024/04/Screenshot-2024-04-08-at-10.08.19-AM-1-198x300.png 198w" sizes="auto, (max-width: 444px) 100vw, 444px" /></figure></div>


<pre class="wp-block-prismatic-blocks"><code class="language-graphql">query ProductDetails {
  product(id: &quot;space-boots&quot;) {
      sku
      name
      details
      rating
      price # The field we want to migrate
    }
}</code></pre>



<p>We want to migrate the <code>Product.price</code> field from our existing monolith to a new microservice. Ideally, this would require no changes to our client or monolith codebase. This is possible with progressive override and the architecture federation provides. Most commonly, teams will begin sending the traffic of the single client view to the hosted Apollo Router instance.</p>



<p>The Apollo Router can handle bridging traffic between your monolith and the new GraphQL service. Some teams will even opt to switch all of a single clients traffic to the router as a step of their progressive rollout (ie. switching the URL in <code>@apollo/client</code> to use the newly hosted router). Even though the router acts as a proxy for the rest of the clients traffic, it paves a golden path for adding new services that further break down the monolith.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="652" height="760" src="https://wp.apollographql.com/wp-content/uploads/2024/04/Group-1-1-1.png" alt="" class="wp-image-23626" srcset="https://wp.apollographql.com/wp-content/uploads/2024/04/Group-1-1-1.png 652w, https://wp.apollographql.com/wp-content/uploads/2024/04/Group-1-1-1-257x300.png 257w" sizes="auto, (max-width: 652px) 100vw, 652px" /></figure>



<p>For our example, we need to create a new subgraph that resolves the <code>Product.price</code> field. This will require us defining <code>Product</code> as an <a href="https://www.apollographql.com/docs/federation/entities">entity</a> using the <code>@key</code> directive and adding the <code>@override</code> directive to <code>Product.price</code>. This requires no changes to our existing monolith or it’s schema:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-"># Existing Monolith
type Product { 
	sku: ID!
	name: String
	details: String
	rating: Float
	price: Float
}
type Query {
	products: [Product]
	product(id: ID!): Product
}</code></pre>



<p><em>There are a lot of </em><a href="https://www.apollographql.com/docs/federation/building-supergraphs/supported-subgraphs"><em>supported servers</em></a><em> you can use to build your GraphQL subgraph in your language of choice like Java, C#, Python and more.</em></p>



<p>Once our router re-configures with the composed schema, it will have the metadata of the <code>label</code> we added (<code>percent(25)</code>). The Apollo Router will then use this information to change the generated query plan based on the percentage label 🎉</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="980" height="650" src="https://wp.apollographql.com/wp-content/uploads/2024/04/Apr-08-2024-14-36-00-1.gif" alt="" class="wp-image-23628"/></figure>



<p>Now the <code>Product.price</code> field of our graph can resolve from a new microservice in our infrastructure and we can progressively rollout this change with simple updates to the schema. Once we’ve moved to 100%, we can eventually <em><strong>delete</strong></em> that code from our monolith 🔥</p>

<p>Progressive override brings a powerful new tool for better flexibility and control in service migration. Embracing incremental adoption in our migrations helps developers navigate the complexities of the organization&#8217;s constantly evolving stack. This also enables platform engineering efforts to tackle self-service migrations for APIs to production 🤯. What would you migrate if you could?</p>



<p>Progressive <code>@override</code> is an <a href="https://www.apollographql.com/docs/router/enterprise-features">Enterprise feature</a> of the Apollo Router and requires an organization with a <a href="https://www.apollographql.com/pricing/?referrer=docs-content">GraphOS Enterprise plan</a>. If your organization doesn&#8217;t have an Enterprise plan, you can test it out by signing up for a free <a href="https://www.apollographql.com/docs/graphos/org/plans/#enterprise-trials">Enterprise trial</a>.</p>

<p><em>Matt DeBergalis, Founder and CTO, Apollo GraphQL</em></p>



<p>Forget what you’ve heard about GraphQL – it’s not a REST alternative, graph database, or just for front-end developers. GraphQL is about combining the APIs you already have.</p>



<p>In this talk, you’ll learn how a federated GraphQL architecture brings a platform approach to API composition, where it fits into the API stack, and what is coming next to help teams build tomorrow’s AI products and experiences on today’s APIs.</p>

<p>In the wake of a recent report by Gartner<sup>®</sup>, <a href="https://apollographql.com">Apollo GraphQL</a>, the creator of GraphQL federation, is announcing the 7th annual GraphQL Summit, scheduled for October 8–10, 2024, in New York City. This premier three-day event gathers the largest assembly of GraphQL enthusiasts and API platform teams. Engineering teams can learn from industry leaders spearheading successful GraphQL deployments at scale and hear from Apollo GraphQL on its product roadmap and vision for the future of GraphQL and GraphQL federation.</p>



<p>According to the Gartner report, GraphQL&#8217;s adoption is on the rise, since “By 2027, more than 60% of enterprises will use GraphQL in production, up from less than 30% in 2024.” The report also predicts that “By 2027, 30% of enterprises using GraphQL will utilize GraphQL federation, up from less than 5% in 2024.”1<sup data-fn="5626a7a6-afc4-465e-84b4-2219decdae0e" class="fn"><a href="#5626a7a6-afc4-465e-84b4-2219decdae0e" id="5626a7a6-afc4-465e-84b4-2219decdae0e-link">1</a></sup> As GraphQL federation marks its<a href="https://www.apollographql.com/blog/celebrating-five-years-of-apollo-federation"> 5th anniversary,</a> Apollo GraphQL remains at the forefront of this transformative technology.</p>



<p>Previous GraphQL Summits have featured internet giants like Netflix, Intuit, and Wayfair, sharing invaluable insights into deploying GraphQL at scale to support distributed architectures. Rather than a sprawl of backends-for-frontends or experience APIs, these teams implemented GraphQL federation, an architecture that combines APIs and enables any number of client teams to query them from a single endpoint. Engineering leaders and API platform teams can learn how to use this architecture to drive developer velocity, enhance the customer experience across any number of applications, or handle the technical side of mergers and acquisitions, where IT is saddled with many disparate siloed systems that were never designed to talk to each other.</p>



<p>This year’s GraphQL Summit aims to support this burgeoning adoption with sessions led by industry luminaries across various sectors, including retail, automotive, and banking.&nbsp; Featured speakers include Stephanie Saunders, Engineering Manager at Coinbase; Mike Cohen, Technical Fellow at Indeed; and Marc-Andre Giroux, Senior Software Developer at Netflix, as well as the co-founders of Apollo GraphQL, Geoff Schmidt and Matt DeBergalis, who will share their insights and expertise on the future of GraphQL and GraphQL federation. Attendees can expect tracks and workshops covering best practices on security, governance, and API platform engineering; real-world use cases and the latest advancements in GraphQL technology; along with a new focus on leveraging GraphQL federation to support artificial intelligence.&nbsp;</p>



<figure class="wp-block-pullquote"><blockquote><p>Geoff Schmidt, CEO and co-founder of Apollo GraphQL, remarks: “As enterprise technology evolves, the rise of GraphQL represents a pivotal shift towards more efficient, scalable, and interconnected systems. The latest insights from Gartner reaffirm what we at Apollo GraphQL have long believed: GraphQL federation is not just a trend, but a fundamental technology shaping the future of digital experiences. Apollo GraphQL is committed to fostering an environment where developers and enterprises can learn, grow, and succeed with GraphQL. The upcoming GraphQL Summit is a reflection of this commitment, featuring talks from industry leaders like Coinbase and Netflix, and promises to be an invaluable opportunity for API platform engineers and leaders to discover how GraphQL federation revolutionizes API architectures for seamless, innovative systems that are driving the future of digital experiences.”</p></blockquote></figure>



<p>All GraphQL enthusiasts are invited to join the conversation by submitting to speak at the Summit. Whether an industry veteran or a newcomer, this is a chance to share insights, experiences, and innovations with the GraphQL community.</p>

Apollo GraphQL Announces the Next GraphQL Summit Amid Rapid GraphQL Enterprise Adoption 


<p>GraphQL federation has emerged as the industry consensus for composing APIs at scale. Organizations such as Netflix, Expedia, and Wayfair quickly adopted this architecture to abstract API complexity and further adoption is on the rise.<a href="https://www.apollographql.com/resources/gartner-when-to-use-graphql-to-accelerate-api-delivery"> Gartner predicts</a> that “By 2027, 30% of enterprises using GraphQL will use GraphQL federation, up from less than 5% in 2024.”<sup data-fn="29ebcf61-2dba-471e-a128-d8d3f07a6d34" class="fn"><a href="#29ebcf61-2dba-471e-a128-d8d3f07a6d34" id="29ebcf61-2dba-471e-a128-d8d3f07a6d34-link">1</a></sup> This pattern didn’t emerge by accident; it was created and refined here at Apollo GraphQL. The first lines of <a href="https://www.apollographql.com/docs/federation/">Federation</a> code were published five years ago, so it’s the right moment to take a step back and examine the past, present, and future of this transformative technology.</p>

<p>Data storage and retrieval needs exploded decades ago, so SQL emerged. Container usage exploded years ago, so Kubernetes emerged. API development is exploding, so GraphQL federation has arrived. It’s declarative, composable, and self-service. Federation isn’t just an idea anymore: it’s a solution that has been proven, at scale, time and again. And according to Gartner, “Federation enables centralized governance, team autonomy (teams can own their own subgraphs), composability, and adaptability to evolving requirements at different speeds.”<sup>1</sup>&nbsp;&nbsp;</p>



<p>We at Apollo GraphQL believe GraphQL federation is now synonymous with GraphQL at enterprise scale. Companies such as Zillow, Square, Priceline.com, and Booking.com rely on Apollo Federation to power their API platforms. Read more about <a href="https://www.apollographql.com/blog/mlbs-api-strategy-hitting-a-home-run-transformation-with-graphql-midfield">how Federation powers Major League Baseball’s API strategy</a> and <a href="https://www.apollographql.com/blog/how-intuit-handled-their-busiest-time-of-year-with-apollo-router">how Intuit handled their busiest time of year with Apollo Router</a>.</p>



<p>These brands chose GraphQL to serve their product and platform goals, allowing them to ship better user experiences faster and without the overhead that legacy API architectures incentivize. Federation is:</p>



<ul class="wp-block-list">
<li><strong>Unified.</strong> Federation preserves the GraphQL experience client teams love by making this data accessible via a single endpoint.</li>



<li><strong>Modular.</strong> Federation makes it easier to break up a monolithic architecture. This enables teams to contribute to the graph independently at scale.</li>



<li><strong>Iterative.</strong> Teams can evolve their graph with confidence, surfacing backwards compatibility concerns early in the process thanks to robust composition rules.</li>
</ul>



<p>Whether you have one service or one thousand, they can all be composed into a single entry point without compromising their existing service boundaries. GraphQL is declarative, flexible, and supported by an open specification. Even if you have a small number of services (as few as one!), Federation can enrich your systems with new features out of the box. This piece isn’t a primer on how to use Apollo Federation, though &#8211; we highly recommend our <a href="https://www.apollographql.com/tutorials/">course catalog in Odyssey</a> for that.</p>

<p><strong>Initial Apollo Federation commits published</strong>. After years of design and months of implementation and building on the vision Martijn Walraven <a href="https://www.youtube.com/watch?v=OFT9bSv3aYAa">spoke about</a> at GraphQL Summit 2018, our first lines of Federation <a href="https://github.com/apollographql/apollo-server/pull/2742">code</a> became complete enough to publish. Shortly afterwards we <a href="https://www.apollographql.com/blog/apollo-federation-f260cf525d21">released</a> Apollo Federation and Apollo Gateway, creating the GraphQL federation category. At GraphQL Summit 2019, <a href="https://www.youtube.com/watch?v=LKQKn1oFXJU">Jeff Hampton</a> and <a href="https://www.youtube.com/watch?v=EDqw-sGVq3k&amp;t=1047s">Matt DeBergalis</a> dove deep into the use case for GraphQL federation, how it works, and what solutions it offers</p>

<p><strong>More expressive graphs</strong>. As developers embraced Federation and our tooling matured, we converged on a more elegant and complete set of <a href="https://www.apollographql.com/docs/federation/federated-types/federated-directives">directives</a> for creating federated graphs. Concepts like entities, owners, and required input data were fully fleshed out with feedback from our enterprise design partners and refined over time.</p>

<p>Apollo is proud to be a founding member of the <a href="https://graphql.org/foundation/">GraphQL Foundation</a> and to be represented on the GraphQL Specification’s Technical Steering Committee and GraphQL Working Group. Since the composition and execution behaviors in Apollo Federation are becoming increasingly adopted by a wide array of users and toolmakers, there is a clear benefit for developing a common standard focused specifically on this domain.</p>



<p>Contributors from Apollo are working with others in the community to <a href="https://github.com/graphql/composite-schemas-spec">collaborate on a proposal</a> for a common specification within the GraphQL Working Group. We are beyond excited at the innovation that this effort will unlock, and thrilled that the community is moving towards a common understanding of the importance of this technology category.</p>

Five Years of Apollo Federation: the Standard for Enterprise API Platforms


<p>At last year’s GraphQL Summit, we learned why <a href="https://www.apollographql.com/blog/redefining-api-strategy-why-netflix-platform-engineering-chose-federated-graphql">Netflix placed a “big bet” on GraphQL federation</a>. We heard about <a href="https://www.apollographql.com/blog/how-intuit-handled-their-busiest-time-of-year-with-apollo-router">Intuit’s measured rollout of Apollo Router</a>. And we learned how <a href="https://www.youtube.com/watch?v=-4R6rLMZ9mc">federated subscriptions</a> enable client teams to deliver real-time updates to their apps – no matter where that data is stored. This year’s <a href="http://www.graphqlsummit.com">GraphQL Summit</a> is in New York City, and we expect an even better event this year.</p>



<p>After just five years, GraphQL federation is becoming a de facto skill to manage API complexity in distributed architectures. In fact, Gartner predicts that <a href="https://www.apollographql.com/resources/gartner-when-to-use-graphql-to-accelerate-api-delivery">30% of enterprises will incorporate GraphQL federation</a> into their stacks within three years. This architecture didn’t just take off at digital-native companies like Netflix, PayPal, and Expedia. It’s now a critical part of the API programs across industries like retail, healthcare, CPG, automotive, and many others. Organizations like Major League Baseball and Volvo Cars chose GraphQL federation to help them deliver immersive, omni-channel, and feature-rich digital experiences at any scale.</p>



<p>So what do the next five years look like for federated graphs? How can larger organizations leverage this architecture to roll out the next generation of personalized, AI-driven applications? That’s the theme of this year’s GraphQL Summit on October 8-10.</p>

Announcing GraphQL Summit 2024 in New York City


<p>GraphQL’s secret sauce is its ability to act as an abstraction layer for service-oriented backends, translating a sea of microservices into a more human-friendly representation of an organization’s data and capabilities. However, as a graph inevitably expands across more and more of the backend, it becomes increasingly difficult for the platform and backend teams that own it to fully understand its structure.&nbsp;</p>



<p>This pain is particularly acute at organizations deploying a federated GraphQL API (also known as a supergraph) at a massive scale with <a href="https://apollographql.com/docs/federation">GraphQL Federation</a>. The distributed nature of developing supergraphs makes it possible to scale them across many independent backend teams and domains, but it also significantly increases the complexity of the relationships in the schema and makes it difficult to find value in existing schema visualization tools which are designed for traditional monolithic graphs.&nbsp;</p>



<p>As the creators of Federation, we want to give API developers a better way to visually explore their supergraph. Today, we’re excited to release native schema visualization in Apollo GraphOS Studio, <strong>free</strong> ( 🎉) for all users. API architects and developers can now use <a href="https://www.apollographql.com/graphos">Apollo GraphOS</a> to visually explore the types, fields, and connections in their graph without running their graph locally, enabling introspection, or spinning up a separate visualization tool.</p>

<p>Historically, generating a schema visualization for a federated graph required jumping through some hoops. You either had to run the graph with introspection enabled (<a href="https://www.apollographql.com/blog/why-you-should-disable-graphql-introspection-in-production">generally not recommended</a> for production graphs) or copy-paste the supergraph SDL into a hosted visualization tool. For extra points, you could spin up your own visualization service and integrate it with your graph’s deployment pipeline, but even then you would probably experience limited returns as most out-of-the-box graph visualization libraries aren’t equipped to handle the scale and complexity of a supergraph.</p>



<p>With GraphOS Studio, you and your team can explore an always-up-to-date visualization of your graph with integrated capabilities like subgraph filtering and entity highlighting that simplify navigation for supergraphs. You can also copy and share a direct link to any view within the visualization to help other developers, product managers, and non-technical contributors understand the structure of the graph.</p>

Visualizing federated GraphQL APIs with GraphOS Studio


<p><a href="https://apollographql.com">Apollo GraphQL</a>, the creator of GraphQL Federation, today announced its membership with the Cloud Native Computing Foundation (CNCF) as a Silver member. This strategic alliance reinforces Apollo GraphQL’s commitment to fostering innovation, enhancing API efficiency, and promoting the importance of GraphQL in platform engineering.&nbsp;</p>



<p>Platform engineering has emerged as one of the top strategic trends for 2024, for which the CNCF recently issued a<a href="https://tag-app-delivery.cncf.io/whitepapers/platforms/"> set of recommendations</a> and a <a href="https://tag-app-delivery.cncf.io/whitepapers/platform-eng-maturity-model/">maturity model </a>defining it. Apollo GraphQL helps API platform teams apply these recommendations to the API layer with Apollo GraphOS, its flagship product. Rather than delivering APIs as a barrage of new endpoints to manage, the Apollo GraphOS platform empowers teams to use GraphQL to build an API composition layer called a &#8216;supergraph&#8217;. This supergraph enables backend teams to connect APIs, and then makes them available to client teams via a single endpoint. Apollo GraphQL now offers a vision to significantly increase developer velocity using a supergraph in its new white paper, <a href="https://www.apollographql.com/resources/platform-engineering-for-apis">“Platform Engineering for APIs: Using GraphQL to Drive Developer Efficiency.”</a>&nbsp;</p>



<p>This approach introduces a self-service, self-documenting system, departing from traditional methods of building experience APIs or backends-for-frontends. It enables client teams to use a declarative query language to fetch the required data for their apps, reducing the cognitive load on product engineering teams. A supergraph also provides a scalable composition layer for backend teams, providing an architecture that can support any number of client applications. Using Apollo GraphOS, platform teams gain the tools to secure, scale, and operationalize a supergraph across any number of teams and applications.</p>



<p>Apollo GraphQL also recently launched a better workflow for backend teams to contribute to the graph with <a href="https://www.apollographql.com/blog/graphos-schema-proposals-a-principled-development-workflow-for-graphql-api-platforms?utm_campaign=2024-02-12_blog_graphos-schema-proposals&amp;utm_medium=social&amp;utm_source=linkedin">schema proposals</a> &#8211; a new centralized change management workflow that streamlines the process of proposing, reviewing, and approving schema changes to a supergraph.</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p>“Platforms are transforming every layer of the stack and the supergraph provides the next chapter of the story — it&#8217;s the architecture of choice for combining services and APIs into coherent, integrated application experiences using GraphQL,” said Matt DeBergalis, CTO and co-founder at Apollo GraphQL. “Joining the Cloud Native Computing Foundation (CNCF) is an important milestone forward for Apollo GraphQL to bring GraphQL into an ecosystem focused on building and shaping the future of cloud-native composable platforms.”</p>

Apollo GraphQL to join Cloud Native Computing Foundation Membership as Silver Sponsor


<p>As an engineering organization grows, the quality of its internal developer platforms directly influences its ability to execute. It’s why <a href="https://www.gartner.com/en/articles/what-is-platform-engineering">80% of large software organizations are expected to establish platform engineering teams by 2026</a> and why many existing platform teams are turning to federated GraphQL APIs, known as <a href="https://www.apollographql.com/docs/resources/glossary/#supergraph">supergraphs</a>, to build self-service API platforms. Client teams leverage these platforms to quickly build features without orchestrating APIs, and backend teams autonomously contribute services from their respective domains via modules called subgraphs.</p>



<p>However, contributions that affect the <em>shape</em> of your supergraph (i.e. the schema) still require cross-team coordination to ensure (1) we are designing the schema in a way that continues to benefit developer velocity, (2) that we don’t break client apps, and (3) that our changes don’t conflict with other backend teams’ subgraph schemas. The modularity of the supergraph can make this coordination tricky since each subgraph schema may live in a different codebase, and not every required contributor or approver may have access to each of those codebases.</p>



<p>Apollo aims to make it easy for any number of teams to better collaborate and contribute to a supergraph. Today, we are excited to announce general availability of <a href="https://www.apollographql.com/docs/graphos/delivery/schema-proposals">GraphOS Schema Proposals</a> – a new centralized change management workflow in GraphOS Studio that streamlines the process of proposing, reviewing, and approving schema changes to a supergraph.</p>

<p>Developers contributing to a supergraph are typically distributed across multiple teams, making it difficult to take advantage of traditional change management workflows that application teams use across a particular codebase. Although these workflows provide the right tooling, they are implemented at too granular of a level, failing to provide the visibility into the overall impact to the supergraph that platform teams require.&nbsp;</p>



<p>GraphOS Schema Proposals provide a purpose-built change management workflow for the API platform layer, allowing developers and platform engineers across multiple teams to propose, review, and approve schema changes.</p>

<p>Proposing a schema change in GraphOS is the first step to making a change to a supergraph. GraphOS Studio now has an integrated schema editor that subgraph developers can use to make changes to existing subgraph schemas or even create new subgraph schemas from scratch.&nbsp;</p>



<p>The schema editor is integrated with all of the other great features of GraphOS Studio, allowing authors to see GraphQL-aware diffing in real time and run linter checks as they work.</p>

<p>Whenever someone saves a revision on a proposal, GraphOS Studio will automatically run <a href="https://www.apollographql.com/docs/graphos/delivery/schema-checks/">schema checks</a> to validate that the proposed schema changes will compose with other existing subgraphs and won’t break client operations.</p>

<p>Once someone on your team has drafted a schema proposal, the author can mark it as <code>OPEN FOR FEEDBACK</code><em> </em>to make it visible to other subgraph, platform, and client developers with the proper permissions. If the proposal needs approval from specific reviewers like a team lead or a potentially affected client developer, the author can request a review from those users.&nbsp;</p>



<p>If your organization has a governance policy that requires certain users to approve every schema change for a graph – a platform team lead, for example – graph admins can add those users as <em>default</em> reviewers from the graph settings page. Admins can also set a minimum number of reviewers required for a proposal to be <code>APPROVED</code>.</p>

<p>Once the minimum number of approvals has been reached and any mandatory default reviewers have approved the proposal, the proposal is marked as <code>APPROVED</code> and is ready for publishing.</p>

<p>In addition to editing and reviews, GraphOS Schema Proposals also provides developers with a streamlined workflow for implementing approved changes locally and safeguards to prevent unapproved changes from being published.</p>



<p>Once a developer has created a proposal, subgraph developers can use Apollo’s Rover CLI to quickly <a href="https://www.apollographql.com/docs/graphos/delivery/schema-proposals/implementation#pull-proposed-schemas-with-rover">pull associated subgraph schemas</a> with rover subgraph fetch. From this point, subgraph developers can then follow the standard steps for developing and delivering changes to their subgraph:</p>



<ol class="wp-block-list">
<li>Make local changes to subgraph server code, including updating or writing new resolvers</li>



<li>Run GraphOS schema checks locally using the Rover CLI (including a new Proposals task to verify that schema changes have a matching approved proposal in GraphOS)</li>



<li>Publish the subgraph schema to GraphOS</li>



<li>Deploy changes to your subgraph server</li>
</ol>



<p><em>(Note: the Schema Proposals workflow </em><strong><em>does not</em></strong><em> automate the above steps, but </em><a href="https://www.apollographql.com/docs/rover/ci-cd/"><em>they can be automated in your CI/CD pipelines using the Rover CLI</em></a><em>)</em></p>

<p>Although the proposals workflow does not automate the deployment process for schema changes, the new Proposal task in the schema checks workflow does provide a safeguard against publishing unapproved changes. Graph Admins can enable or disable the Proposal task in graph settings, and they can also configure the severity of the check to <code>Error</code> or <code>Warn</code>.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1600" height="797" src="https://wp.apollographql.com/wp-content/uploads/2024/02/proposals-diff.png" alt="" class="wp-image-23346" srcset="https://wp.apollographql.com/wp-content/uploads/2024/02/proposals-diff.png 1600w, https://wp.apollographql.com/wp-content/uploads/2024/02/proposals-diff-300x149.png 300w, https://wp.apollographql.com/wp-content/uploads/2024/02/proposals-diff-1024x510.png 1024w, https://wp.apollographql.com/wp-content/uploads/2024/02/proposals-diff-768x383.png 768w, https://wp.apollographql.com/wp-content/uploads/2024/02/proposals-diff-1536x765.png 1536w, https://wp.apollographql.com/wp-content/uploads/2024/02/proposals-diff-1200x598.png 1200w" sizes="auto, (max-width: 1600px) 100vw, 1600px" /></figure>



<p>Setting the Proposal task severity to <code>Error</code> will cause schema checks to fail if any schema changes do not have a matching approved proposal. This includes schema checks that are run locally as well as when a schema is published to GraphOS, ensuring that unapproved changes are never published to the supergraph.</p>

GraphOS Schema Proposals: a principled development workflow for GraphQL API platforms


<p>Over the past two years, the emergence of AI-driven tools has significantly transformed the tech landscape. Among these innovations, tools designed specifically for code generation—such as Copilot, CodeLlama, and others—have garnered particular attention from developers.&nbsp;</p>



<p>According to a survey conducted by GitHub, 92% of U.S.-based developers are already using AI coding tools both in and outside of work <a href="https://github.blog/2023-06-13-survey-reveals-ais-impact-on-the-developer-experience/">(source)</a>.</p>



<p>These tools offer immense value for tasks like rapid prototyping and brainstorming, serving as powerful allies in the development process. However, despite their advanced capabilities, a notable gap exists in their ability to generate high-quality GraphQL schemas.</p>



<p>I&#8217;m sure most, if not all of us, wish to craft the finest GraphQL schema possible—even if it&#8217;s just for a prototype. If you’ve watched my <a href="https://www.youtube.com/watch?v=p4jP2xnImAM">“Let&#8217;s Build a Supergraph Using ChatGPT” talk at GraphQL Summit</a>, you might know some of the ways you can steer tools like ChatGPT to improve the output of the generated code.</p>



<p>But let&#8217;s be real. The results aren&#8217;t always perfect, and it almost feels like ChatGPT clings onto some less-than-desirable practices! Consider this scenario: when I request ChatGPT to construct a schema for a note-taking application, this is the outcome:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">type Query {
  getNotes: [Note]
  getNoteById(id: ID!): Note
  getTags: [Tag]
}

type Mutation {
  createNote(title: String!, body: String!): Note
  createTag(name: String!): Tag
  addTagToNote(noteId: ID!, tagId: ID!): Note
}

type Note {
  id: ID!
  title: String!
  body: String!
  tags: [Tag]
}

type Tag {
  id: ID!
  name: String!
  notes: [Note]
}
</code></pre>



<p>Clearly, this schema has room for improvement. It includes generally discouraged practices like utilizing &#8216;get&#8217; in query fields and lacking important elements like pagination. It also overlooks important components such as mutation payloads and input types, essential for successful schema evolution.</p>



<p>During my presentation, I shared our experience with fine-tuning GPT-3.5 for optimized GraphQL schema generation. We did notice improvements on schema generation from the standard models, but it wasn&#8217;t flawless. On numerous occasions, the model failed to meet our set guidelines for schema generation or it was generating schemas that were less than ideal.</p>



<p>So we’ve been working more to make the output much better and make sure it would follow the best practices as often as possible, and we are finally ready to share it with you all!</p>



<p>To try it is pretty simple! <a href="https://discord.gg/SzeywawCa6">Join our Discord server</a>, go to the <strong>#ai-schema-design</strong> forum and post a message describing the schema you’d like to create, for example:</p>



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p><strong>Title:</strong> Note taking application&nbsp;</p>



<p>I&#8217;m building a note taking application. Users can create notes, and each note has a title and a body. Users can also create tags, and each tag has a name. Users can add tags to notes, and notes can have multiple tags.</p>
</blockquote>



<p>Then after submitting the bot will create a schema based on your inputs! The more specific you are the better the schema will be 😊And you’ll be able to keep iterating with the bot to improve the schema or even to see some operation that you could run with your schema</p>



<p>Here’s an example of the schema generator in action:</p>



<figure class="wp-block-video"><video autoplay controls loop muted src="https://wp.apollographql.com/wp-content/uploads/2024/02/CleanShot-2024-02-05-at-18.48.38.mov" playsinline></video></figure>

Fun with AI – Generating GraphQL Schemas in Discord


<p>Modern apps must support real-time use cases like flight changes, team collaboration, or live score updates for the big game. GraphQL subscriptions push events in a more efficient and performant way compared to traditional client-side polling of RESTful services that try to pull new events every few seconds. Instead of polling, clients can subscribe to the specific data they require, and the graph immediately delivers those events as they occur, reducing backend load and providing faster real-time updates.</p>



<p>Traditionally, GraphQL subscriptions have been implemented with WebSockets, an approach with many issues, including compression, debugging, scalability, and compatibility with firewalls, load-balancers, and other networking infrastructure.</p>



<p>We addressed the frontend portion of the WebSocket problem in June 2023, when we announced <a href="https://www.apollographql.com/blog/federated-subscriptions-in-graphos-real-time-data-at-scale" target="_blank" rel="noreferrer noopener">Federated subscriptions in GraphOS</a> with support for a new <a href="https://www.apollographql.com/docs/react/data/subscriptions/#subscriptions-via-multipart-http" target="_blank" rel="noreferrer noopener">HTTP multipart protocol</a> based on the underlying protocol for GraphQL @defer support in <a href="https://www.apollographql.com/docs/router/executing-operations/defer-support/" target="_blank" rel="noreferrer noopener">Apollo Router</a>. This makes hosting a real-time API in any cloud environment easier, with all the benefits of a standard HTTP connection.</p>



<p>However, on the backend, Apollo Router supports legacy WebSocket protocols for compatibility with existing subgraph APIs, which is inefficient at scale. For example, if a subscription can’t be <a href="https://www.apollographql.com/docs/router/executing-operations/subscription-support/#subscription-deduplication" target="_blank" rel="noreferrer noopener">deduplicated</a>, 1 million client subscriptions would require 1 million backend WebSockets connections.&nbsp;</p>



<p>Today, we are excited to announce the GA release of Apollo Router 1.37 with <a href="https://www.apollographql.com/docs/router/executing-operations/subscription-callback-protocol/" target="_blank" rel="noreferrer noopener">HTTP callback support</a>, designed in partnership with the GraphQL community. HTTP callback support solves the backend WebSocket problem and dramatically reduces the number of open subgraph connections. This results in the same great performance but with more efficiency at scale and reduces real-time cloud spend for router and subgraph deployments.</p>

<p>Subscription callbacks offer new levels of flexibility and interoperability between the router and underlying services. By default, federated subscriptions use WebSockets, which requires two long-lived connections for every client: one between the client and the router and one between the router and the subgraph. Additionally, these long-lived connections aren’t well suited for serverless infrastructures.&nbsp;</p>



<p>With HTTP callbacks, on the other hand, the router no longer manages a WebSocket connection with subgraphs, and it’s flexible enough to be used with other Pub/Sub architectures that can support HTTP requests.</p>

<p>If your application already uses the preview of subscription callbacks, there are a few things to change in your Router configuration to migrate to the GA:</p>



<ol class="wp-block-list">
<li>Change the name of the option from <code>subscription.mode.preview_callback</code> to <code>subscription.mode.callback</code>. Failure to use the updated option name when running the router will result in an error, and the router won&#8217;t start.</li>



<li>Update the <code>public_url</code> field to include the full URL of your callback endpoint. Previously, in the preview, the public URL used by the router was the automatic concatenation of the <code>public_url</code> and <code>path</code> fields. In GA, the behavior has changed, and the router uses the value set in <code>public_url</code>. This enables you to configure your public URL, for example, if you have a proxy in front of the router and want to configure redirection with the public URL.</li>



<li>Configure the new <code>heartbeat_interval</code> field to set the period that a heartbeat must be sent to the callback endpoint for the subscription operation. The default heartbeat interval is 5 seconds.

</ul>



<p>Let&#8217;s dive in!</p>



<h2 class="wp-block-heading"><a href="#suspense-enabled-data-fetching-in-response-to-user-interaction-with-useloadablequery" aria-hidden="true" class="aal_anchor" id="suspense-enabled-data-fetching-in-response-to-user-interaction-with-useloadablequery"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Suspense-enabled data fetching in response to user interaction with <code>useLoadableQuery</code></h2>



<p>When it comes to Suspense-enabled data fetching in Apollo Client, <code>useSuspenseQuery</code> and <code>useBackgroundQuery</code> are useful for loading data as soon as the component calling the hook mounts. But what about loading a query in response to user interaction? For example, you may want to start loading some data when a user hovers on a link.</p>



<p>Introducing the <code>useLoadableQuery</code> hook 🎉 For more information, see <a href="https://www.apollographql.com/docs/react/data/suspense#fetching-in-response-to-user-interaction">its documentation</a>.</p>



<h2 class="wp-block-heading"><a href="#preloading-data-outside-of-react-with-createquerypreloader-and-preloadquery" aria-hidden="true" class="aal_anchor" id="preloading-data-outside-of-react-with-createquerypreloader-and-preloadquery"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Preloading data outside of React with <code>createQueryPreloader</code> and <code>preloadQuery</code></h2>



<p>Starting with Apollo Client 3.9, queries can be initiated outside of React. This allows your app to begin fetching data <em>before</em> React renders your components, and can provide performance benefits.</p>



<p>To preload queries, you first need to create a preload function with <code>createQueryPreloader</code>. <code>createQueryPreloader</code> takes an <code>ApolloClient</code> instance as an argument and returns a function that, when called, initiates a network request.</p>



<p>The preload function returns a <code>queryRef</code> that is passed to <a href="https://www.apollographql.com/docs/react/api/react/hooks/#usereadquery"><code>useReadQuery</code></a> to read the query data and suspend the component while loading. <code>useReadQuery</code> will ensure that your component is kept up-to-date with cache updates for the preloaded query.</p>



<p>This feature pairs nicely with popular routers such as React Router and TanStack Router, both of which provide APIs for loading data before route components render (such as the <a href="https://reactrouter.com/en/main/route/route#loader"><code>loader</code> function</a> from React Router). It provides the benefits of earlier fetching without sacrificing the ability to automatically re-render when future cache updates occur.</p>



<p>This feature is in alpha in 3.9 and may be subject to change before 3.10. If you&#8217;d like to provide feedback before it&#8217;s stabilized, please visit <a href="https://github.com/apollographql/apollo-client/issues/11519">#11519</a> and add a comment.</p>

<p><code>useQueryRefHandlers</code> is a hook that returns <code>refetch</code> and <code>fetchMore</code> functions for a given <code>queryRef</code>. It&#8217;s useful for gaining access to these handlers for a <code>queryRef</code> that was created by <code>createQueryPreloader</code>, or to avoid passing these handlers down through your component tree.</p>

<p>Spanning over twenty memory-related pull requests, 3.9 includes a host of improvements and optimizations related to memory usage.</p>



<p>You can find a comprehensive list in <a href="https://www.apollographql.com/blog/author/lenz">Lenz</a>&#8216;s December <a href="https://www.apollographql.com/blog/apollo-3-9-beta-feature-spotlight-the-memory-story">blog post</a>, but at a high level this work includes many fixes and improvements and introduces <strong>the ability to granularly configure Apollo Client’s internal memoization</strong>.</p>



<p>Memoization is always a trade-off between processing time and memory, and some of our old cache limits erred on the side of consuming more memory. While the new defaults should be sufficient for most applications, we know that some will need to make different trade-offs so we made each cache size individually configurable, both before and after the Apollo Client has been initialized. </p>

<p>With the launch of <a href="https://www.youtube.com/watch?v=-4R6rLMZ9mc&amp;list=PLpi1lPB6opQzUOqG3QroLLN06FF-Q_uhX&amp;index=5">federated subscriptions</a> in the Apollo Router last year, Apollo Client added support for GraphQL <a href="https://www.apollographql.com/docs/react/data/subscriptions/#subscriptions-via-multipart-http">subscriptions over HTTP</a>.</p>



<p>In 3.9, we&#8217;re shipping network adapters for Relay and urql to make consuming subscriptions via multipart HTTP a breeze no matter which client library you&#8217;re using.

<p>This release also introduces two frequently requested improvements to the testing utility, <code>MockedProvider</code>:</p>



<ul class="wp-block-list">
<li><strong>Reusing mocks:</strong> By default, a mock is only used once. If you want to reuse a mock for multiple operations, you can now set the <code>maxUsageCount</code> field to a number indicating how many times the mock should be used.</li>



<li><strong>Dynamic variables:</strong> The <code>MockedResponse</code> object now takes a <code>variableMatcher</code> property that is a function that takes the variables and returns a boolean indication if this mock should match the invocation for the provided query. This can be useful when the exact value of the variables being passed are not known, or for asserting specific variables individually.</li>
</ul>

What’s new in Apollo Client 3.9


<p>As platforms, teams, and products evolve, we sometimes need new or different ways to deploy our APIs. Strong Continuous Integration / Continuous Deployment (CI/CD) practices and recovery strategies are necessary components of any <a href="https://aws.amazon.com/blogs/mt/establishing-rpo-and-rto-targets-for-cloud-applications/" target="_blank" rel="noreferrer noopener">Recovery Time Objective (RTO) and Recovery Point Objective (RPO)</a>. </p>



<p>The recommended GraphOS <a href="https://www.apollographql.com/tutorials/workshop-summit-graphos-basics/08-changes-process" target="_blank" rel="noreferrer noopener">continuous deployment</a> process uses <a href="https://www.apollographql.com/docs/federation/managed-federation/uplink/" target="_blank" rel="noreferrer noopener">Apollo Uplink</a> to update the Router fleet in place with new supergraph schemas that pass checks in the GraphOS build pipeline along with automated testing in lower environments such as dev or test. However, some organizations have specific deployment needs that rely on an immutable schema for blue-green deploys or canary releases.</p>



<p>Today, Apollo is excited to release enhanced GraphOS Platform APIs that streamline integration with immutable blue-green and canary deployments workflows beyond the in-place continuous GraphOS updates that most customers use today:</p>



<ol class="wp-block-list">
<li><a href="https://studio.apollographql.com/graph/apollo-platform/variant/main/schema/reference/objects/GraphMutation?_gl=1*1yu3yv*_ga*NDMzNzY1NzQ4LjE3MDI5MTM0MDk.*_ga_0BGG5V2W2K*MTcwNTEwMzIwNC4zMi4xLjE3MDUxMDM1NzEuMC4wLjA.#publishSubgraphs" target="_blank" rel="noreferrer noopener">PublishSubgraphsMutation</a> will publish all of the releases’ subgraphs as a single unit and return the associated launch and downstream Contract launches.</li>



<li><a href="https://studio.apollographql.com/graph/apollo-platform/variant/main/schema/reference/objects/Launch#status" target="_blank" rel="noreferrer noopener">PollLaunchStatusQuery</a> will poll for the status of any individual launch by ID.</li>



<li><a href="https://studio.apollographql.com/graph/apollo-platform/variant/main/schema/reference/scalars/GraphQLDocument" target="_blank" rel="noreferrer noopener">FetchSupergraphSDLQuery</a> will fetch the supergraph schema of the launch.</li>
</ol>



<p>These GraphOS Platform API updates are versatile enough to support many deployment strategies.</p>



<p><a href="https://www.apollographql.com/docs/federation/managed-federation/deployment/#example-blue-green-deployment" target="_blank" rel="noreferrer noopener">Blue-green deployment</a> involves maintaining two identical production environments: the &#8220;Blue&#8221; and the &#8220;Green.&#8221; Only one of these environments is live at any given time. When it&#8217;s time to deploy an update to a supergraph, the team releases it to the inactive environment. For instance, the new version is deployed to “Green” if “Blue” is live. Once the new “Green” version is thoroughly tested and deemed stable, the team switches traffic from “Blue” to “Green.” With these updates to the GraphOS Platform API, <a href="https://www.apollographql.com/docs/graphos/metrics/" target="_blank" rel="noreferrer noopener">metrics and insights</a> for both stages, the “Blue” and the “Green,” are available in a consolidated place under a single Production variant, which has a single launch history to track schema changes over time.</p>



<p><a href="https://www.apollographql.com/docs/federation/managed-federation/deployment/#example-canary-deployment" target="_blank" rel="noreferrer noopener">Canary deployment</a>, on the other hand, is a more gradual process. It involves first rolling out the new supergraph updates to a small subset of users rather than switching simultaneously. This subset, or &#8220;canary group,&#8221; receives the update and is closely monitored by the platform team for any issues. If the deployment is successful, the team rolls out the update to a more significant portion of the user base and eventually to all users.</p>



<p>While we recommend rolling forward to recover in most cases, <a href="https://www.apollographql.com/docs/federation/managed-federation/deployment/#rolling-back-a-deployment" target="_blank" rel="noreferrer noopener">rollbacks</a> can be helpful in some scenarios. For example, consider a blue-green deployment where a team deploys the Router and all subgraphs as a single versioned release and houses <strong>immutable schemas</strong> within each Docker image. Then, if the need arises for a rollback, they can simply re-deploy the old Docker images, and the correct supergraph schema will be used. This helps ensure compatibility with existing blue-green workflows that assume an immutable infra mindset.</p>



<p>For platform teams looking to enhance their GraphQL platform stance, stay tuned for additional GraphOS Platform API updates and learn more about <a href="https://www.apollographql.com/docs/federation/managed-federation/deployment/" target="_blank" rel="noreferrer noopener">deployment and rollback examples in the GraphOS documentation</a>.</p>


New GraphOS Platform APIs Enable Blue-Green and Canary Deployments


<p>Building a scalable and effective enterprise <a href="https://www.apollographql.com/blog/introducing-apollo-graphos">supergraph</a> is challenging, and often feels like there are countless numbers of ways to approach the challenges that arise without evidence of efficacy. Companies searching the GraphQL community for recommendations leads to&nbsp; a lack of consistency across the industry and doing things that may prove to be ineffective, thus requiring changes later down the line. These challenges can often be exacerbated by the lack of consensus both internally and externally, making it difficult to know what works best.</p>



<p>Apollo aims to simplify this process for both existing and new GraphQL practitioners and today we’re excited to share the <a href="https://saf.apollographql.com">Supergraph Architecture Framework (SAF)</a>, which is the culmination of years of learning by Apollo’s Solutions Architecture team after working with some of the largest enterprise organizations in the world as a way to answer questions about how to best enable your organization to scale GraphQL effectively.</p>

<p>The SAF explains key concepts, design principles, and architectural best practices for running a supergraph in production. The five SAF pillars provide an ideal foundation for a supergraph, ensuring your team can get up and running successfully in less time.&nbsp;</p>



<p>The SAF is a short assessment to help you and your organization better understand how to improve your supergraph, grouped into five pillars. These questions are based on best practices we’ve seen at other companies who have deployed a supergraph at enterprise scale.</p>



<p>The pillars are:&nbsp;</p>



<ul class="wp-block-list">
<li><strong>Operational Excellence</strong>: How you efficiently operate, maintain, and manage your supergraph. This pillar primarily focuses on the interpersonal skills and processes that are paramount to running a successful supergraph.</li>



<li><strong>Security</strong>: How you secure your organization’s supergraph to prevent misuse.&nbsp;</li>



<li><strong>Reliability</strong>: How you build and maintain a scalable supergraph with high availability in mind.</li>



<li><strong>Performance</strong>: How you can create a performant supergraph and ensure performance is monitored at your organization.</li>



<li><strong>Developer Efficiency</strong>: This discusses ways to increase your developer velocity through process improvements.&nbsp;</li>
</ul>



<p>Once completed, you’ll be able to get a report of how your organization is performing, alongside a list of action items and their associated impact and level of effort.</p>



<p>The SAF is intended to be run multiple times as your journey progresses, and can be helpful at any stage of the process; whether that be the beginning or midway through implementation, or reviewing an existing implementation to make changes.</p>

The Apollo Supergraph Architecture Framework


<ul class="wp-block-list">
<li><em>GraphQL Leader Adds Executives from Atlassian and Twilio; Aditya Phadke Appointed Chief Customer Officer and Rob Brazier Named VP of Product</em></li>



<li><em>Unwavering GraphQL Adoption and Customer Focus Continue to Drive Major Product Enhancements at Apollo GraphQL&nbsp;</em></li>
</ul>



<p>Apollo GraphQL, the supergraph company, today announced it has made two significant additions to its leadership team, welcoming Aditya Phadke as Chief Customer Officer and Rob Brazier as VP of Product. These new appointments build on the successes felt in 2023, as GraphQL saw a rise in usage and success within API platform teams for globally recognized brands like <a href="https://www.youtube.com/watch?v=b78Q7qY4IpI&amp;list=PLpi1lPB6opQzUOqG3QroLLN06FF-Q_uhX&amp;index=7">Netflix</a>, <a href="https://www.youtube.com/watch?v=sNqcow1psEA&amp;list=PLpi1lPB6opQzUOqG3QroLLN06FF-Q_uhX&amp;index=24">Wayfair</a>, and <a href="https://www.youtube.com/watch?v=GB-THCI0Mw0&amp;list=PLpi1lPB6opQzUOqG3QroLLN06FF-Q_uhX&amp;index=36">Intuit</a>.</p>



<p>Phadke joins Apollo GraphQL from Atlassian, where he played a crucial role in unlocking customer success and building its pre-sales &amp; post-sales customer motions as it scaled from a startup to a public market leader worth $62B; he will be responsible for building the post-sales group fostering long-term customer relationships and evolving the customer adoption journey. Brazier most recently joins from Grammarly, where he led their developer platform efforts and, prior to that, was the VP of Product at Twilio, where he focused on Twilio Flex, Voice and Video, and other product lines for the company. He brings his background in platforms, developer-facing products and cloud, alongside experience with top-down and bottom-up sales motions, to further advance all aspects of the Apollo GraphQL product portfolio that is seeing significant adoption as the leader of GraphQL products in the market. Additionally, Robbie Petrie joined as Chief Financial Officer earlier in 2023 from Twilio to round out the leadership team.</p>



<figure class="wp-block-pullquote"><blockquote><p>“In 2024, brands are delivering personalized, AI-driven applications across multiple channels to keep up in today&#8217;s market. They’re finding that it’s hard to do this at the pace today’s world requires without a new approach to APIs. Rather than building handwritten experience APIs for each customer interface, enterprises are taking a platform approach with GraphQL so they can gain composability, developer velocity, and efficient integration of diverse cloud resources. And that’s why they’re turning to Apollo GraphQL as the creators of the industry standard GraphQL platform for the future,” said Geoff Schmidt, CEO and co-founder at Apollo GraphQL. “We are expanding our executive team to better service our customers and meet demands for their long-term growth and success. Aditya brings a track record of nurturing customer relationships and Rob brings years of developer platform success and expertise. Both make ideal additions to the Apollo GraphQL leadership team to help developers build the next generation of applications and deliver profound, efficient, and meaningful user experiences.”</p></blockquote></figure>

Apollo GraphQL Expands Leadership Team To Meet Demand for GraphQL in the Enterprise


<p>Although many in the industry consider GraphQL a replacement for existing API technologies, it is at its most powerful when used as a central orchestration layer between apps and existing services. This layer, implemented as a federated graph (or <a href="https://www.apollographql.com/blog/announcement/backend/the-supergraph-a-new-way-to-think-about-graphql/">supergraph</a>, for short), acts as a self-service API platform that accelerates development velocity for both frontend and backend teams. However, speed of delivery can’t come at the expense of a strong authorization model that protects personal identifiable information, financial data, and other sensitive information.</p>



<p><a href="https://www.apollographql.com/graphos">Apollo GraphOS</a> provides GraphQL-native workflows to implement access control declaratively across an entire supergraph. Rather than relying only on distributed enforcement or fragile custom gateway logic to secure the graph, teams using GraphOS can enforce policies at the type or field level in their router by decorating schemas with the <code>@requiresScopes</code>, <code>@authenticated</code>, and new <code>@policy</code> directives. These directives provide the freedom to integrate with any authorization system, including policy engines like <a href="https://casbin.org/">Casbin</a> or <a href="https://www.openpolicyagent.org/">Open Policy Agent</a> (OPA). By proactively enforcing policies as code, API platform teams can ensure compliance at all times without sacrificing developer velocity.</p>



<p>These directives are generally available for all GraphOS Enterprise customers starting today.</p>

<p>Supergraphs expose a unified, versionless GraphQL endpoint for all connected services. While this offers a host of benefits for frontend development, it makes it tricky to centralize authorization with traditional API gateways designed to enforce policies at the endpoint level. These gateways are unaware of the shape of the supergraph, so policies need to be mapped to individual types and fields with custom logic that must be kept in lockstep coordination with any schema changes.</p>



<p>An authorization model that is instead integrated directly into a supergraph’s schema is far more durable and can still be centrally audited and enforced in the router. <code>@authenticated</code> and <code>@requiresScopes</code>, <a href="https://www.apollographql.com/blog/announcement/backend/build-centralized-graphql-authorization-with-apollo-graphos/">which we launched in preview</a> earlier this year, allow you to define access control policies for types and fields directly in the schema, restricting access to only authenticated requests or requests with certain scopes, respectively. Subgraph developers simply add the directives to the parts of the schema they want to enforce.</p>



<p>For example, let’s say you’re building a simple social media app. The app should allow unauthenticated users to view a post&#8217;s title, author, and content, but only authenticated users to see the number of views a post has received, and only certain users with required permissions to view email addresses. The relevant part of your schema may look something like this:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">type Query {
  me: User @authenticated 
  post(id: ID!): Post
}

type User {
  id: ID!
  username: String
  email: String @requiresScopes(scopes: [[&quot;read:email&quot;]])
  posts: [Post!]!
}

type Post {
  id: ID!
  author: User!
  title: String!
  content: String!
  views: Int @authenticated 
}</code></pre>



<p>However, many organizations may require more complex policy evaluation and often leverage external tools like OPA or Casbin. For these more complex scenarios, GraphOS now supports a third authorization directive: <code>@policy</code>.</p>



<h2 class="wp-block-heading"><a href="#offload-policy-definition-and-resolution-with-policy" aria-hidden="true" class="aal_anchor" id="offload-policy-definition-and-resolution-with-policy"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Offload policy definition and resolution with @policy</h2>



<p>The new <code>@policy</code> directive allows you to integrate your predefined policies from policy engines like OPA and Casbin into your supergraph schema and enforce them in your router. For example, let’s say in your example social media app, you only want users to have access to their own personal information and credit card information. Validating this requires more than the scopes of an access token, so you can use <code>@policy</code> to offload policy resolution for the relevant parts of your schema:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">type Query {
  me: User @authenticated @policy(policies: [[&quot;read_profile&quot;]])
  post(id: ID!): Post
}

type User {
  id: ID!
  username: String
  email: String @requiresScopes(scopes: [[&quot;read:email&quot;]])
  posts: [Post!]!
  credit_card: String @policy(policies: [[&quot;read_credit_card&quot;]])
}

type Post {
  id: ID!
  author: User!
  title: String!
  content: String!
  views: Int @authenticated
}</code></pre>



<p>The <code>@policy</code> directive allows you to use your supergraph as a central enforcement point for any services you’ve connected to your graph without refactoring the authorization model that you’ve already defined.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1600" height="800" src="https://wp.apollographql.com/wp-content/uploads/2023/12/external-policy-diagram.png" alt="" class="wp-image-23033" srcset="https://wp.apollographql.com/wp-content/uploads/2023/12/external-policy-diagram.png 1600w, https://wp.apollographql.com/wp-content/uploads/2023/12/external-policy-diagram-300x150.png 300w, https://wp.apollographql.com/wp-content/uploads/2023/12/external-policy-diagram-1024x512.png 1024w, https://wp.apollographql.com/wp-content/uploads/2023/12/external-policy-diagram-768x384.png 768w, https://wp.apollographql.com/wp-content/uploads/2023/12/external-policy-diagram-1536x768.png 1536w, https://wp.apollographql.com/wp-content/uploads/2023/12/external-policy-diagram-1200x600.png 1200w" sizes="auto, (max-width: 1600px) 100vw, 1600px" /></figure>



<p><code>@policy</code> loosely couples policy enforcement in your GraphOS router and the policy definition in your existing policy engine, giving you the flexibility to evolve how your application resolves policies without altering your GraphQL schema or infrastructure. For example, if your application needs to perform complex authorization validation, such as inspecting specific values in headers, <code>@policy</code> can be used to validate in a coprocessor or Rhai script.&nbsp;</p>

New GraphQL observability and insights in GraphOS Studio


<p>Apollo Federation is an open specification for exposing API services as a single GraphQL access layer, known as a supergraph. In a supergraph, you connect and curate your services through smaller, modular graphs called subgraphs. There’s a vibrant ecosystem of community-led frameworks that let you write subgraphs in <a href="https://www.apollographql.com/docs/federation/building-supergraphs/supported-subgraphs">every common language</a>, bolstered by official Apollo Federation support libraries for JavaScript and Java. </p>



<p>Today, we’re excited to announce a new <a href="https://www.nuget.org/packages/ApolloGraphQL.HotChocolate.Federation">official Apollo Federation support library for Hot Chocolate</a> — a popular .NET GraphQL framework — including full <a href="https://www.apollographql.com/blog/announcement/backend/announcing-federation-2/">Federation 2</a> support for field migrations, entity interfaces, and more flexible type ownership!</p>

<p>With momentum building in the .NET community, more and more subgraphs are being created using community support for Federation in popular GraphQL packages like GraphQL .NET and Hot Chocolate. To better support the growing number of .NET subgraphs, we&#8217;re excited to announce official Apollo support for .NET with a new v1.0 <a href="https://www.nuget.org/packages/ApolloGraphQL.HotChocolate.Federation">Apollo Federation support library for Hot Chocolate</a>. It’s an open source library that adds Federation support to the main Hot Chocolate GraphQL server and is based on the previous community-led implementation for backwards compatibility. We’ve fixed a few things, overhauled the docs, and added support for Federation 2!</p>



<p>Official <a href="https://www.apollographql.com/docs/federation/building-supergraphs/supported-subgraphs/#c--net">compatibility testing for C# / .NET</a> shows comprehensive Federation 2 support for Hot Chocolate:</p>

Announcing official Apollo Federation support for .NET with Hot Chocolate and Federation 2!


<p>Unbounded operations are generally considered a benefit of GraphQL, giving client developers unprecedented flexibility when experimenting and developing apps. However, while this flexibility is greatly appreciated in development environments, allowing it in production adds unnecessary surface area to GraphQL endpoints which generally serve only first-party clients.</p>



<p>Instead, your production graph should adhere to the principle of least privilege. If your first-party apps only require <code>QueryA</code>, <code>QueryB</code>, and <code>QueryC</code> to operate properly, your graph should only allow <code>QueryA</code>, <code>QueryB</code>, and <code>QueryC</code>. Any tolerance for ad hoc operations creates unnecessary exposure.</p>



<p>If you have a GraphQL monolith serving just a few clients, building a custom safelisting system to enforce this behavior is relatively straightforward. However, as the graph scales to serve dozens of clients and takes on a supergraph architecture, the complexity of maintaining such a system becomes prohibitive.</p>



<p>Apollo now offers a scalable solution for mitigating the risks of unbounded operations in supergraphs: <strong>GraphOS Persisted Queries</strong>. Persisted queries enable your platform team to limit the attack surface area of your supergraph by centrally registering trusted GraphQL operations and safelisting them in any instance of the Apollo Router.</p>

<p>A supergraph is a self-service API platform designed to empower frontend and backend teams to consume and build services independently, but equally important is its ability to systematically centralize access control policy enforcement. By choosing to leverage the supergraph for policy enforcement, API platform teams can protect any number of backend services with layers of access control without heavy-handed manual review.</p>



<p>GraphOS Persisted Queries is one such layer that centralizes policies defining which <em>operations</em> should be allowed access to the supergraph. Rather than relying on platform teams to create and maintain this policy manually, GraphOS provides a workflow for <a href="https://www.apollographql.com/docs/graphos/operations/persisted-queries#implementation-steps">discovering and registering known operations</a> that can be integrated directly into client CI/CD pipelines.</p>

<p>In most cases, your production API only needs to execute a finite number of GraphQL operations from a set pool of stable, first-party applications. In this environment, safelisting limits the exposure of your graph by blocking any unknown operations.&nbsp;</p>



<p>However, in development environments, it’s important to allow developers the flexibility to experiment with unbounded operations. To do so, you can configure your router to simply <a href="https://www.apollographql.com/docs/graphos/operations/persisted-queries#security-levels">log any unregistered operations</a> rather than block them. This is also useful when you’re getting started with Persisted Queries, and you haven’t yet registered all known operations from existing clients. However, it can be useful to pair this mode with some <a href="https://www.apollographql.com/docs/router/configuration/operation-limits/">operation limits</a> that prevent any intentional or unintentional misuse of the graph.</p>

<p><em>An Integrated Blueprint from Kong and Apollo</em> </p>



<p>Not a day goes by where the tech press fails to mention industry advancements in AI, connected devices, or personalization. Consumers can now use AI to create anything from digital illustrations to vacation ideas. At the core of these initiatives is one tried-and-true constant – APIs. If an organization cannot safely and securely deliver service updates across any number of interfaces, these modernization initiatives will fail to gain traction.</p>



<p>APIs are more heterogeneous than ever though. An enterprise considering incorporating gRPC APIs may still have legacy SOAP APIs in the mix. A new feature could require data from 20 different services – all of which are managed by different teams at different cadences using varying protocols. If a Product Manager wants to incorporate data from legacy APIs as well as new options like ChatGPT, how can API platform teams provide a standardized means to iterate, secure access, and scale all of them? And then how do they ensure that client teams can get the data they need in a self-service fashion?</p>



<p>Kong and Apollo are industry leaders in the API space. Our customers come to us with these very real problems everyday. The API ecosystem often positions REST and GraphQL as competing technologies, but they are highly complementary and are instrumental in developing a modern API platform that accomplishes the goals above. Through a balanced exploration of Kong&#8217;s perspective on flexible, heterogeneous API ecosystems and Apollo&#8217;s expertise in GraphQL, we’ve captured the vendor-neutral best practices that combine API management and GraphQL into a unified reference architecture for building and operating a modern API platform.</p>



<p>Learn more with our joint <a href="https://new.apollographql.com/leveraging-graphql-for-next-generation-api-platforms.pdf">paper and reference architecture</a> that shows how to:</p>

Leveraging GraphQL for Next-Generation API Platforms


<p><em>December 2023 update: GraphOS authorization enforcement is <strong>now generally available</strong>, including the <code>@requiresScopes</code>, <code>@authenticated</code>, and <strong>new</strong> <code>@policy</code> directives. <a href="https://www.apollographql.com/blog/announcement/backend/centrally-enforce-policy-as-code-for-graphql-apis/">Read the GA announcement</a>.</em></p>



<hr class="wp-block-separator has-alpha-channel-opacity"/>



<p>Implementing a durable access control system for APIs is critical to prevent data breaches, monetary losses, and potential denial of services. GraphQL presents API owners with a unique challenge in this regard because it is designed for maximum flexibility.</p>



<p>In general, there are two choices for enforcing access control for GraphQL APIs, neither of which scale particularly well. You can write custom logic to centralize enforcement — which must be kept in lock-step coordination with changes to the graph — or you can distribute enforcement across multiple GraphQL endpoints — eliminating much of the flexibility GraphQL provides to app developers.</p>



<p>Apollo GraphOS and <a href="https://www.apollographql.com/blog/announcement/backend/the-supergraph-a-new-way-to-think-about-graphql/">supergraph architecture</a> are eliminating this trade-off. Starting today, graph owners can enforce centralized authorization across any number of connected services in the graph.</p>



<p><a href="https://www.apollographql.com/docs/router/configuration/authorization/">Authz enforcement</a> is available<strong> in preview today</strong> for all customers on the GraphOS Enterprise plan running self-hosted instances of Apollo Router.</p>

<p>When you operate a supergraph with GraphOS, you can now use the <code>@requiresScopes</code> and <code>@authenticated</code> <a href="https://www.apollographql.com/docs/router/configuration/authorization/#authorization-directives">directives</a> to define the authorization model for individual types and fields in each of your services declaratively. Rather than relying on custom logic or per-service access control, GraphOS uses these directives to compose a single federated authorization model. It then enforces that model in your <a href="https://www.apollographql.com/docs/router/">graph router</a> at the edge of the API stack to optimize query execution and improve defense-in-depth.</p>



<h3 class="wp-block-heading"><a href="#limit-access-to-certain-scopes" aria-hidden="true" class="aal_anchor" id="limit-access-to-certain-scopes"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Limit access to certain scopes</h3>



<p>The <strong><code>@requiresScopes</code> </strong>directive is useful in cases where certain data or experiences should be available to a subset of users, but not all. It allows you to define granular access control by specifying an array of scopes that are required to access the type or field. If GraphOS receives a request that is missing the required scopes for certain fields, it will automatically filter out those fields before executing the operation. [<a href="https://www.apollographql.com/docs/router/configuration/authorization/#example-requiresscopes-use-case">Example use case</a>]&nbsp;</p>



<h3 class="wp-block-heading"><a href="#require-authentication" aria-hidden="true" class="aal_anchor" id="require-authentication"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Require authentication</h3>



<p>The <strong><code>@authenticated</code></strong> directive is useful when you need to limit access to unauthenticated users (or when you want to cut off unauthenticated access entirely). It provides binary access control, limiting marked types and fields to authenticated requests. When GraphOS receives an unauthenticated request, it filters out all fields marked with <code>@authenticated</code> before execution.

<p>The best way to combat DoS attacks is to enforce access control well before traffic ever reaches your mission-critical services. With an access control model defined in your schema, the GraphOS runtime plane acts as a central control point that does just that. In the simplest case, GraphOS will immediately terminate requests lacking the proper authorization to access any fields, preventing them from ever reaching your services. However, GraphOS can also optimize the execution of partially authenticated requests and deduplicate requests to your services.</p>

<p>Let’s say we’re building the profile page for a social media app that shows profile information like a name and profile image to all users, but only shows the posts associated with the profile to authenticated users. We have one service in our federated graph that handles user information — the Users API — and another that handles post information — the Posts API. We can restrict access to data resolved by the Posts API to authenticated users with <code>@authenticated</code>.</p>



<p>Now, when GraphOS receives the query used to populate the profile page, it will first check if the user has the proper claims to access fields resolved by the Posts API. Here’s the fun part – if the request doesn’t have the proper claims, GraphOS will eliminate the entire subquery to the Posts API, preventing that service from ever seeing the traffic.</p>

<p>Implementing centralized GraphQL authorization with GraphOS eliminates the need for maintaining custom gateway code or bespoke authorization models for every one of your services. On top of that, it optimizes the performance of your services by eliminating unnecessary load from unauthorized requests.</p>



<p>Starting today, all customers on the GraphOS Enterprise plan can start using <code>@requiresScopes</code> and <code>@authenticated</code> to enforce declarative, graph-native authorization in the GraphOS runtime plane. To get started, head over to the <a href="https://www.apollographql.com/docs/router/configuration/authorization/">GraphOS documentation</a>.</p>

Build centralized GraphQL authorization with Apollo GraphOS


<p>When you’re building a federated GraphQL API that spans multiple backend teams and services, it can be difficult to ensure that the schema for your graph stays consistent from subgraph to subgraph. For example, how do you ensure that a type defined as an entity in one subgraph is also defined as an entity in all other subgraphs?</p>



<p>Today, we’re making it easier for API platform teams to enforce schema consistency across multiple subgraphs by adding composition rules to the <a href="https://www.apollographql.com/blog/announcement/platform/standardize-graphql-schema-linting-policies-with-graphos/">Apollo GraphOS linter</a>. Now, you can configure the GraphOS checks workflow to flag inconsistent elements across subgraphs, overridden or unused elements, and issues with Federation directives.</p>

<p>Like other linter rules in GraphOS, you can enable or disable each composition rule independently and set its severity to <code>Warn</code> or <code>Error</code>. Violations of rules set to <code>Error</code> will cause the checks workflow to fail outright (useful for changes pushed to production graphs) while <code>Warn</code> violations will allow the checks workflow to pass but output a warning.</p>

<p>Last year, we announced the End-of-Life for Apollo Server 3, originally scheduled for October 22, 2023. Apollo Server has widespread adoption, and we&#8217;ve heard feedback that some in the community would appreciate more time for the migration process. In light of this, <strong>we&#8217;re extending the End-of-Life date for Apollo Server 3 to October 22, 2024</strong>. Apollo will continue to provide security patches and fixes for major regressions until October 2024, after which Apollo Server 3 will no longer be maintained by Apollo. </p>



<p>To learn how to migrate to Apollo Server 4, see the <a href="https://www.apollographql.com/docs/apollo-server/migration/">migration guide</a>. Additionally, you can find more information about End-of-Life stages in the <a href="https://www.apollographql.com/docs/resources/product-launch-stages/#end-of-life">Apollo Launch Stages definitions</a>.</p>

Apollo Server 3 end-of-life extension


<p>GraphQL is designed to offer a more flexible, self-serve developer experience, but its open-ended approach often raises questions about its security model. The most common objection is that GraphQL APIs allow unbounded operations — a trait that can degrade performance or result in denial-of-service if too many complex queries are sent to the endpoint. A <a href="https://www.apollographql.com/blog/the-supergraph-a-new-way-to-think-about-graphql/">supergraph architecture</a> can compound this risk since it generally composes many services across an organization, significantly increasing the potential complexity of executing queries.</p>



<p>In order to deliver performance and security at all times, API platform teams should have the means to eliminate exposure to the potential performance impacts of excessively complex queries. In the spirit of a true platform, teams should be able to <strong>proactively define safelisted queries upfront in a way that encourages iteration in development but provides mission-critical security in production</strong><em>.&nbsp;</em></p>

<p>Today, Apollo is introducing a new approach for preventing unbounded access to GraphQL APIs: <a href="https://www.apollographql.com/docs/graphos/operations/persisted-queries"><strong>GraphOS persisted query safelisting</strong></a>. With persisted query safelisting, API teams can prevent service degradation from complex queries by centrally safelisting known operations in <a href="https://www.apollographql.com/docs/router/">Apollo Router</a> — Apollo’s blazing-fast GraphQL gateway and query planner.&nbsp;</p>



<p>GraphOS offers varying levels of safelist restrictions that enable incremental adoption and flexibility in development environments without sacrificing security in production. The <em>audit-only</em> configuration gives teams a frictionless way to get started with safelisting by logging unknown operation shapes without terminating the request. Meanwhile, production environments demanding maximum security and performance can use an <em>ID-only</em> configuration to accept only requests with a known hash, terminating all others.</p>



<p>Persisted query safelisting is available in preview today for Apollo customers on the GraphOS Enterprise plan – read the docs and try it out! We would love to hear your thoughts and learn how we can make safelisting work better for your use case. Over the coming weeks, we’ll be using your feedback to polish up the user experience ahead of the GA release.&nbsp; <a href="https://www.apollographql.com/docs/graphos/operations/persisted-queries">Head to the docs</a> to get started or read on to learn more about how you can configure safelisting for your development lifecycle.</p>

<p>Nearly all APIs are designed to serve a finite set of first-party client apps, and, by their very nature, GraphQL services are aware of the shape of data requested by those applications. In this closed development ecosystem, we have the tools to implement a GraphQL gateway that significantly limits surface area by <em>only</em> allowing known operations from our first-party apps.&nbsp;</p>



<h3 class="wp-block-heading"><a href="#register-operations-from-first-party-apps" aria-hidden="true" class="aal_anchor" id="register-operations-from-first-party-apps"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Register operations from first-party apps</h3>



<p>GraphOS gives client teams a self-serve experience for registering queries from their first-party apps to a central graph registry. Simply generate a persisted query manifest file for any app using Apollo Client (web, iOS, or Kotlin) and register it to a graph in GraphOS using the Rover CLI. The persisted query manifest includes a unique <em>persisted query ID</em> hash for each operation which can be used in place of the query string to improve app performance once persisted queries are configured in the router.</p>

<p>After client teams register known queries to a graph in GraphOS, API platform owners can enable persisted queries for connected instances of Apollo Router. Once enabled, the router pulls the list of persisted query strings and IDs from the graph registry and stores them in memory to be used for safelisting and ID-only operations.&nbsp;</p>



<p>Enforcing severe safelisting rules in the router is as simple as updating a few lines of router config, but to prevent any breaking changes in your apps, it is best to start with a flexible configuration and incrementally move to a more restrictive approach in production. In the remainder of this post, we’ll walk through the various ways you can adapt safelisting to your use case.</p>

<p>Generally, you should configure your router to be more restrictive in production environments and less restrictive in development environments, but your particular use case and GraphQL client may limit how restrictive your router can be. GraphOS offers the ability to enforce more severe or less severe safelisting restrictions depending on your use case.&nbsp;</p>

<p>In development environments or when you’re just getting started with safelisting, it is generally best to simply log any unregistered operations without terminating them. The audit-only configuration provides this flexibility, helping you determine if any operations are missing from the registry in GraphOS. Here’s how you can configure your router for audit-only:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-yaml"># router.yaml

<p>ID-only operations are the most restrictive, but they also are the most efficient since the router can avoid processing any complex, freeform query strings (similar to <a href="https://www.apollographql.com/docs/router/configuration/distributed-caching/"><em>automatic</em> persisted query caching</a>). In this mode, <strong>clients are required to send requests to the router with <em>only</em> a unique persisted query ID</strong> which the router can use to identify the requested operation. The router will reject any requests with an invalid ID or a freeform query string.&nbsp;</p>

<p>ID-only operations are supported by all Apollo Clients — web, iOS, and Kotlin — but support in other libraries may vary.&nbsp;</p>

<p>In the case that your GraphQL client does not support ID-only operations, you can use less stringent shape-based safelisting. Shape-based safelisting is also useful in cases where ID-only operations are excessively restrictive. For example, it may be useful for pre-production apps to query a staging graph using the full query string for easier debugging. In these cases, you can use the default option for safelisting which will accept operations without a persisted query ID as long as they match the shape of a registered operation:</p>

<p>Safelisting known operations in your router contributes yet another layer to your defense-in-depth strategy for your API platform. However, like any security measure, is most effective when layered with additional checks.</p>

<p>One of the best checks to combine with safelisting is a general <a href="https://www.apollographql.com/docs/router/configuration/operation-limits/">limit on operation complexity</a>. Setting a maximum height, depth, number of aliases, and number of root fields for any given operation creates a safety net to prevent accidentally or intentionally malformed queries from impacting the performance of your API.&nbsp;</p>



<p>These limits are table-stakes for public endpoints where safelisting isn’t an option but are also helpful in-house to prevent excessively complex operations from accidentally being safelisted.</p>



<h3 class="wp-block-heading"><a href="#limit-scope-of-access" aria-hidden="true" class="aal_anchor" id="limit-scope-of-access"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Limit scope of access</h3>



<p>Safelisting restricts incoming requests to preregistered operations, but for compliance purposes, you may also need to limit the scope of data available in a particular endpoint. For example, if you have a supergraph that contains PCI, you may need a separate endpoint for client apps that removes that information.</p>



<p>With GraphOS you can use <a href="https://www.apollographql.com/docs/graphos/delivery/contracts/">contracts</a> to systematically create filtered endpoints that remove any sensitive or unnecessary information. For each of your filtered endpoints, you can create a tailored query safelist specific to its clients.</p>

<p>Apollo Kotlin is a strongly-typed client library that generates models from your GraphQL queries. This works thanks to a Gradle plugin that triggers the code generation at build time. Normally, after touching a graphql file, to be able to use the up-to-date generated models in your Kotlin code, you would need to manually run the codegen Gradle task.</p>



<p>With the IDE plugin, this is done automatically: the codegen is run in the background whenever you touch your GraphQL queries, so you can use the models immediately.</p>

<p>Apollo Kotlin 3 was a major version that introduced quite a few changes compared to version 2. While some of <a href="https://www.apollographql.com/docs/kotlin/migration/3.0/">these changes</a> require manual tweaks to the code, a lot of these can be automated. Which is what the “Migrate to Apollo Kotlin 3” action does. If you are still on version 2, now is a good time to migrate!</p>

<p>When editing Kotlin code that references GraphQL queries, it is often useful to go to their definition &#8211; for instance, if you need to add a field to the selection. The natural way to do that in Android Studio is to <code>Cmd/Ctrl + click</code> (or <code>Cmd/Ctrl + b</code> on the keyboard) on the symbol. However without any special knowledge of Apollo Kotlin or GraphQL, this would go to the generated code, which is not as useful. Not anymore! The plugin adds target to go to the GraphQL definition:</p>



<figure class="wp-block-video"><video controls src="https://wp.apollographql.com/wp-content/uploads/2023/06/03-go-to-declaration.mov"></video><figcaption class="wp-element-caption">Go to GraphQL definition</figcaption></figure>



<p>Note that the generated code destination is still there, as it is sometimes handy to have a look at it.</p>



<p>We’ve also added these nifty GraphQL icons in the gutter next to operation and fragment references. Click on them to go to the definition.</p>



<p>To go to the Schema instead, use “Go To Type Declaration” (<code>Cmd/Ctrl + Shift + click</code>, or <code>Cmd/Ctrl + Shift + b</code>):</p>



<figure class="wp-block-video"><video controls src="https://wp.apollographql.com/wp-content/uploads/2023/06/04-go-to-type-declaration.mov"></video><figcaption class="wp-element-caption">Go to the schema</figcaption></figure>



<p>The reverse works too if you need it: “Find Usages” on your GraphQL operation will list Kotlin files referencing them:</p>

Announcing the Apollo Kotlin plugin for Android Studio and IntelliJ IDEA


<p>When it comes to writing code collaboratively, consistency is everything. APIs are no exception. In fact, APIs are perhaps the most important place to ensure consistency, since they act as a vein for collaboration across nearly every developer in an organization&#8217;s ecosystem.</p>



<p>For GraphQL APIs, the schema is at the heart of all collaboration and consumption, but ensuring consistency in a graph that spans many teams, tools, and workflows is no easy task. Today, we’re excited to make things a bit easier by adding <a href="https://www.apollographql.com/docs/graphos/delivery/schema-linter">schema linting</a> to Apollo GraphOS!&nbsp;</p>



<p>As an API platform owner, linter checks in GraphOS will help you keep your schema syntax clean and consistent by validating that schema changes pass pre-defined formatting and naming rules like:</p>



<ul class="wp-block-list">
<li>Field names should be <code>camelCase</code></li>



<li>Input type names should be suffixed with <code>Input</code></li>



<li>The <code>@tag</code> directive should use a pre-approved value for its <code>name</code> argument</li>
</ul>

<p><strong>Starting today, schema linting is available for all orgs on the GraphOS Enterprise and Serverless plans.</strong> Linter checks will automatically run whenever new schema changes are published to GraphOS, but you can also run checks manually on a local schema or in a separate CI/CD pipeline using the Rover CLI.</p>

<p>GraphOS schema linting is designed to integrate seamlessly into your existing processes to ensure that your schema’s syntax stays consistent at every stage of graph development.</p>

<p>No one wants to reread all of the code they just wrote to figure out where they miscapitalized one field. Using <a href="https://www.apollographql.com/docs/rover">the Rover CLI</a>, devs can run schema linting on their local schema as they work to ensure that their changes pass when published.</p>



<p>To run schema linting locally, just <a href="https://www.apollographql.com/docs/rover/getting-started">install Rover</a>, authenticate, and run <a href="https://www.apollographql.com/docs/rover/commands/graphs#graph-lint"><code>rover graph lint</code></a> or <a href="https://www.apollographql.com/docs/rover/commands/subgraphs#subgraph-lint"><code>rover subgraph lint</code></a>.</p>

<p>Linting locally helps individual developers work quickly, but keeping a cross-team code base consistent requires enforcing linter rules centrally. Similar to other linting tools you may use, GraphOS schema linting can be integrated directly into your existing CI/CD pipelines to ensure that every schema change is checked before being published, no matter who it comes from.</p>



<p>To run schema linting in a third-party CI/CD tool, just <a href="https://www.apollographql.com/docs/rover/ci-cd/">install the Rover CLI as part of your pipeline</a>.</p>

<p>GraphOS gives you a central source of truth for all of your schemas and, if you have a <a href="https://apollographql.com/docs/federation">federated graph</a>, acts as the final checkpoint for your schema before your graph router uses it in production.&nbsp;</p>



<p>Running linter checks for new changes published to your schema in GraphOS ensures consistency in all of your running graphs.</p>



<p>If you already have schema checks set up in GraphOS, linter checks will automatically be added to your checks workflow! You can review the status of linter checks on the checks page in GraphOS Studio.</p>

<p>The linter in GraphOS comes with a pre-defined list of rules that cover common best practices for writing GraphQL schemas. You can customize the severity of each rule independently to <code>Off</code>, <code>Warn</code>, or <code>Error</code> in GraphOS Studio under Checks &gt; Configuration &gt; Linter.</p>



<p>When set to <code>Warn</code>, a rule violation will allow the checks workflow to pass but output a warning, whereas a violation of a rule set to <code>Error</code> will cause the checks workflow to <em>fail</em> outright.</p>

<p>You can also choose to have the linter ignore definitions marked with <code>@deprecated</code> or <code>@inaccessible</code> to prevent errors caused by outdated or private definitions.</p>



<h2 class="wp-block-heading"><a href="#start-linting" aria-hidden="true" class="aal_anchor" id="start-linting"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Start linting!</h2>



<p>Starting today, linting is enabled for every organization on GraphOS Enterprise and Serverless plans. All you need to do to get started is publish a change to your graph! If you have schema checks enabled, you’ll automatically see linter checks as a new step.&nbsp;</p>



<p>If you want to change the linter configuration for your graph, head to the “Checks” tab in GraphOS Studio → Configuration → Linter. Or if you haven’t set up schema checks yet for your graph, check out <a href="https://www.apollographql.com/docs/graphos/delivery/schema-checks">the documentation</a> to get started.</p>


Standardize GraphQL schema linting policies with GraphOS


<p>A GraphQL API with the power to give app developers everything they need in a single query is excellent for delivery velocity, but it also could have the potential to enable improper access to data if not secured correctly.&nbsp;</p>



<p>With supergraph architecture, you can mitigate this risk by implementing the proper security controls in each subgraph, but Apollo GraphOS is helping platform teams add an additional layer of security in front of subgraphs by building controls into the graph router itself.</p>



<p>Router security is one of the key themes in our 2023 GraphOS roadmap, and today we’re excited to ship a preview of our newest router security feature for GraphOS Enterprise: operation size and complexity limiting.</p>



<h2 class="wp-block-heading"><a href="#centralized-protection-from-misuse" aria-hidden="true" class="aal_anchor" id="centralized-protection-from-misuse"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Centralized protection from misuse</h2>



<p>For production graphs, preventing accidental or intentional misuse is a key requirement. If not protected properly, client apps can issue expensive queries that cause excessive load on the server potentially resulting in denial of service. Even in less extreme cases, poorly formed queries can still impact the performance of client apps and lead to a slower user experience.</p>



<p>There are a variety of packages designed to limit operation complexity and cost at the server level; however, as a federated graph grows, it can become increasingly difficult to set, standardize, and maintain these limits across many subgraphs owned by different teams. Luckily, supergraph architecture presents us with the unique opportunity to centralize control in a single point: the router.</p>



<p>Enforcing operation size and complexity limits in the graph router makes it far easier to standardize policies for a large graph and alleviates the burden of coordinating limits across every subgraph.</p>



<h2 class="wp-block-heading"><a href="#limit-depth-height-root-fields-and-aliases" aria-hidden="true" class="aal_anchor" id="limit-depth-height-root-fields-and-aliases"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Limit depth, height, root fields, and aliases</h2>



<p>Just like it sounds! With GraphOS Enterprise, you can now configure your router to limit the depth, height, number of root fields, and number of aliased fields of any incoming GraphQL operation. If an operation exceeds any of the set limits, the router will reject it before attempting to resolve the request with a <code>400 BAD_REQUEST</code> status code.</p>



<p>All of these limits can be configured in the <code>router.yaml</code> file for any router authenticated with your GraphOS Enterprise credentials:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-yaml">preview_operation_limits:
  max_depth: 100
  max_height: 200
  max_root_fields: 40
  max_aliases: 30</code></pre>



<p>Optionally, you can also configure the router to only log a warning message for operations that exceed the set limits rather than rejecting the operation outright:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-yaml">preview_operation_limits:
  # some limits
  warn_only: TRUE</code></pre>



<p><code>warn_only</code> defaults to <code>FALSE</code>, but it can be useful to set it to <code>TRUE</code> in development environments for testing purposes.</p>

Prevent graph misuse with operation size and complexity limits


<p>Just over a year ago, we introduced Apollo Router, the graph router that is now at the heart of Apollo GraphOS. Unlike its predecessor <a href="https://www.apollographql.com/docs/apollo-server/using-federation/api/apollo-gateway/">Apollo Gateway</a>, Apollo Router was designed to&nbsp;maximize the performance benefits of GraphQL and <a href="https://www.apollographql.com/blog/announcement/backend/the-supergraph-a-new-way-to-think-about-graphql/">supergraph architecture</a>, while being secure by default. After switching to the router, one customer reported a <strong>93% reduction in gateway cloud spend</strong>, a <strong>30x reduction in Kubernetes Pod counts</strong>, and 70% less code to maintain – while delivering even faster response times, with <strong>a 70% reduction in request latencies</strong>!&nbsp;</p>



<p>Today, some of the world’s largest companies rely on GraphOS for their mission-critical graph API infrastructure. Routers have processed 100% of Black Friday traffic for top-100 retail companies, and major fintech organizations are trusting their routers to handle tax season.</p>



<p><em>So what’s next?</em></p>



<p>Many of Apollo Router’s initial users are running billions of operations each month with GraphOS. The features in this release focus on the challenges of operating a graph router at massive scale: <strong>defense in depth, maximizing performance, and extensibility</strong>. Today, we are excited to make three new features generally available to GraphOS Enterprise customers running a self-hosted router: JWT auth, distributed APQ caching, and support for external coprocessors.</p>

<p><strong>Block malicious traffic at the edge of your graph with new JWT auth support in the router.</strong></p>



<p>Previously, the router could only forward user access tokens (JWT) generated by identity providers like Auth0 or Okta onto subgraphs and underlying REST APIs. Keeping your supergraph secure meant doing JWT checks in every subgraph or REST API which allows attackers deeper into your graph – and missing a single check often results in security holes.</p>



<p>Now, with the router as a <a href="https://doyensec.com/resources/Doyensec_Apollo_Report_Q22022_v4_AfterRetest.pdf">security-hardened</a> entry point to your graph, you can reject malicious traffic early and shield your subgraphs and REST APIs from unwanted traffic. Router v1.12 adds support for <a href="https://www.apollographql.com/docs/router/configuration/authn-jwt">JWT validation, claim extraction, and custom security policies in Rhai scripting</a> to reject bad traffic at the edge of the graph – for enhanced zero-trust and defense-in-depth. Extracting claims once in the router and securely forwarding them to subgraphs has several key benefits, including: </p>



<ul class="wp-block-list">
<li><strong>Reducing operational burden on backend API teams</strong> &#8211; no JWT keys to manage</li>



<li><strong>Reducing latency due to JWT processing</strong> &#8211; since the JWT is processed only once in the router</li>



<li><strong>Speeding up response times</strong> &#8211; by selectively forwarding JWT claims for increased <a href="https://www.apollographql.com/docs/router/configuration/traffic-shaping/#query-deduplication">query deduplication</a></li>
</ul>



<p>These performance benefits compound at scale, particularly if the router is simultaneously processing similar queries.</p>



<h2 class="wp-block-heading"><a href="#maximize-performance-at-scale" aria-hidden="true" class="aal_anchor" id="maximize-performance-at-scale"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Maximize performance at scale</h2>



<p><strong>Reduce p99 latency during peak traffic with Distributed APQ (automatic persisted query) caching with Redis.</strong></p>



<p><a href="https://www.apollographql.com/docs/apollo-server/performance/apq/">APQ</a> can drastically reduce response latency by allowing clients to send only a unique hash over the wire instead of a large query document, providing a fast path to query execution. You may already have in-memory APQ configured for your router, however when load balancing requests over a large fleet of router instances, the in-memory cache won’t be consistently hot. Unlucky users, especially during scaling events, will hit cold caches and experience slower response times as the APQ cache must be built individually in each router instance.</p>



<p>With Router v1.12 , you can now use <a href="https://www.apollographql.com/docs/router/configuration/distributed-caching">distributed APQ caching</a> to improve p99 latencies during peak times. A shared Redis instance can now be used by the entire router fleet to build the APQ cache faster and share existing APQ cache with new router instances that are spun up during scaling events – when they need it most. This ensures the fast path to query execution is consistently available to all users even during peak load.</p>

<p><strong>Extend the router in your language of choice using new external coprocessor support.</strong></p>



<p>To create common customizations for Apollo Gateway like header propagation and error handling, you have to code plugins and middleware directly into a custom gateway package. These monolithic gateway packages must be built and deployed as a single unit, often requiring coordination across teams. Since everything is run in a single process, errors in the custom code can crash the whole Gateway, and it’s not clear which team should be paged at 3 am to resolve the issue.</p>



<p>With Apollo Router, most common customizations are built directly into the stock binary and <a href="https://www.apollographql.com/docs/router/configuration/overview">can be configured with YAML</a>. YAML config alone allowed one of our largest Enterprise customers to eliminate 70% of their custom Gateway code.</p>



<p>In cases where the YAML config isn’t enough, Router also supports Rhai scripting (similar to Lua in NGINX and Envoy) which can be used for in-memory manipulation of headers, cookies, and more with a well-defined <a href="https://www.apollographql.com/docs/router/customizations/rhai-api">Rhai API reference</a>. Rhai scripts are great for lightweight customizations and provide a safe, sandboxed way to customize the Router’s request flow.</p>



<p>For more powerful customizations, the Router now supports <a href="https://www.apollographql.com/docs/router/configuration/external">external coprocessors</a> written in the programming language of your choice. Coprocessors run with full isolation and a clean separation of concerns, that decouples delivery and provides fault isolation. Low overhead can be achieved by running coprocessors alongside the router on the same host or in the same Kubernetes Pod as a sidecar. Coprocessors can be used to speed Gateway migrations, support bespoke use cases, or integrate the router with existing network services for custom auth (JWT mapping, claim enrichment), service discovery integration, and more!</p>



<p>However, our goal is to eliminate as much custom code as possible, so if you have a common use case that you think should be supported in the stock Apollo Router binary, be sure to <a href="https://github.com/apollographql/router/issues">open an issue</a>.</p>

<p><strong>Upgrade to Router v1.12 and ensure they are connected to GraphOS with an Enterprise plan.</strong></p>



<p>All Apollo GraphOS Enterprise customers can access these features today for self-hosted instances of Apollo Router. If your router is already connected to GraphOS Studio using your <code>APOLLO_KEY</code> and <code>APOLLO_GRAPH_REF</code>, and you’re running the latest version of Apollo Router, no further action is required! You can set up all of these features in your existing router config. See <a href="https://www.apollographql.com/docs/router/enterprise-features">the documentation</a> for additional details.</p>



<p>These are just the first of many router features on the roadmap for GraphOS. We have exciting security and performance features coming up soon for GraphOS Enterprise as well as GraphOS Cloud, so stay tuned!</p>

Virtual Events – Deep Dive into Schema Design Best Practices


<p>The Apollo CLI <code>service</code> commands are now officially deprecated and will reach their <strong>final end of life on April 28th, 2023.</strong></p>



<p><strong>Note: </strong>Apollo will continue to provide support for the Apollo CLI <code>client</code> commands.</p>



<p>Rover is the command line interface for managing and maintaining graphs through GraphOS with over 10 million all-time downloads and over 4 million command invocations per day. If you are still using Apollo CLI’s <code>service</code> commands and would like to migrate to the Rover CLI, please refer to this migration <a href="https://www.apollographql.com/docs/rover/migration/">guide</a>.</p>



<p>For more information regarding Apollo’s software lifecycle policies and an up-to-date list of actively maintained software versions, please visit the Apollo launch stages <a href="https://www.apollographql.com/docs/resources/product-launch-stages/">documentation</a>.</p>


Announcing the end-of-life schedule for Apollo CLI service commands


<p>Almost a year ago we introduced <a href="https://www.apollographql.com/blog/announcement/platform/save-and-share-your-graphql-operations-in-apollo-explorer/">operation collections</a> in GraphOS as a way to save your frequently used operations in Explorer and share them with your team. Today, we are making saved operations even more useful with operation scripts! Now, you can write scripts for your saved operations to build automated testing workflows that call other saved operations.</p>



<h2 class="wp-block-heading"><a href="#what-are-operation-scripts" aria-hidden="true" class="aal_anchor" id="what-are-operation-scripts"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>What are operation scripts?</strong></h2>



<p>Operation scripts are a brand new, <strong>free 🎊</strong> feature in GraphOS Studio that let you write scripts that run before your operation to execute JavaScript code, make HTTP requests, and run other saved operations before your current operation. You may think this sounds a lot like what you can do with <a href="https://www.apollographql.com/blog/announcement/tooling/automatically-authenticate-with-preflight-scripts-in-apollo-studio-explorer/">preflight scripts</a>, and you would be correct! An operation script, at a high level, is a preflight script that is defined <em>per operation</em> instead of <em>per variant</em>.</p>



<p>With operation scripts you and your team can:</p>



<ul class="wp-block-list">
<li>Easily debug the behavior of individual operations when they’re provided various values</li>



<li>Design and write scripted workflows with your saved operations for testing</li>
</ul>

<p>Adding operation scripts to your saved operations is easy. To get started, head to Explorer in GraphOS Studio, open up the Operation Collections tab on the left panel, and open the operation you would like to write a script for. In the bottom pane, you’ll see a new tab named Script.</p>

<p>In your script, you can also run <em>other</em> saved operations from any variant of your graph against your current endpoint using the <code>runOperation</code> command. This allows you to use values from the output of those operations as GraphQL variables for your current operation.&nbsp;</p>



<p>Below is an example of using <code>runOperation</code> to get a list of ships from the SpaceX GraphQL API and then passing the ID of the <code>firstShip</code> to an environment variable.</p>



<pre class="wp-block-prismatic-blocks"><code class="language-javascript">const response = await explorer.runOperation({
 scope: &#039;shared&#039;,
 graphRef: &#039;SpaceX-pxxbxen@current&#039;,
 collectionName: &#039;Mission Control&#039;,
 operationName: &#039;Ships&#039;,
})

const firstShipID = response.result.data.ships[0].id

explorer.environment.set(&#039;shipID&#039;, firstShipID)</code></pre>



<p>From here you can use any environment variables set in your script by passing them into the GraphQL variables panel. For instance, if I had this script set on a mutation that takes in a <code>shipID</code> and then sets the <code>status</code> of the ship to <code>Launched</code>, I would use the following GraphQL variables in my variables panel:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">{
  &quot;shipID&quot;: &quot;{{ shipID }}&quot;,
  &quot;status&quot;: &quot;Launched&quot;,
}</code></pre>



<p>When you run your operation, it will run your script, populate your variables, and then run the current operation. Amazing! Now you can build operation workflows without you having to go back and forth between tabs copying and pasting values! And, if you forget the names of your saved operations or collections, the script editor provides automatic IntelliSense to suggest names of collections and operation names. To trigger it you can start typing <code>&#039;&#039;</code> and it will provide a dropdown for you to choose from.</p>

Automate GraphQL query testing in GraphOS Explorer!


<p>You’ve heard it a million times: <em>everything you need, and nothing more, all in a single query</em>. It’s the core promise of GraphQL, but it presents a challenge. To truly get everything in a single query, you need to put everything you have<em> </em>into a single graph.</p>



<p>At Apollo, we’ve spent the better part of three years designing a GraphQL architecture to address that challenge — we call it <a href="https://www.apollographql.com/blog/announcement/backend/the-supergraph-a-new-way-to-think-about-graphql/">supergraph architecture</a>. Its main component is a graph router, which sits in front of your GraphQL servers and has a query planner to execute queries across multiple connected graphs. Just over a year ago, we released Apollo Router, our graph router binary, which is now used by Fortune 500 companies to run billions of operations each month for mission-critical applications.</p>



<p>But Apollo Router enables much more than just scale. It enables faster, more reliable, and more intelligent query execution for any GraphQL API by layering in support for directives like <code>@defer</code> and entity types. We want to bring these benefits and more to every developer in the world that uses GraphQL, not just those in a massive company.</p>



<p>That’s why today, we’re excited to announce general availability of <strong>Apollo GraphOS Cloud</strong> — a cloud-hosted platform with instant-on access to blazing-fast graph routing for any GraphQL API and integrated tools for rapid query development, collaboration, and schema design. Anyone with a GraphQL API can <a href="https://studio.apollographql.com/signup">start using GraphOS Cloud</a> today with 10 million free queries per month our Serverless plan. Serverless is a great way for developers and teams to evaluate GraphOS or even GraphQL. From startups to proofs-of-concept for your enterprise, Serverless is an easy way to try all that Apollo GraphOS has to offer.</p>

<p>At the heart of GraphOS Cloud is an edge graph router (built on Apollo Router) that enhances your existing GraphQL API with the latest runtime features of GraphOS. The router in GraphOS Cloud is so much more than just a GraphQL API gateway. It’s a runtime that is fully aware of the structure of data available to your connected GraphQL server, and it can manipulate how queries are executed to improve performance.</p>

<p>Most graphs start out small, but they can be a headache to scale across teams when the time comes. GraphOS Cloud has built-in support for Apollo Federation, so you can easily add to your graph modularly with subgraphs whenever you need to. It also automatically keeps your hosted router up-to-date with the latest version of Apollo Router, so you never need to worry about new version rollout.</p>



<p>GraphOS Cloud also integrates your router with a delivery pipeline to prevent breaking changes when collaborating on a graph with multiple subgraphs and client apps. Whenever GraphOS detects a change to one of your schemas, it will automatically recompose a supergraph schema for your router, check it against historic operations from registered client apps, and update your router with the new supergraph schema.</p>

From the Trust Center, you can learn about Apollo’s approach to earning customer trust, and, most importantly, you can request and download a wide variety of Apollo’s security, compliance, and legal documentation including:</p>



<ul class="wp-block-list">
<li>Apollo’s SOC 2 report</li>



<li>Summaries of third-party penetration tests for Apollo GraphOS and Apollo Router</li>



<li>Prefilled industry-standard security questionnaires</li>



<li>All of our published reliability metrics</li>



<li>Apollo’s legal documentation required for privacy alignment</li>
</ul>



<p>It’s everything that we expect from vendors, in a single portal, tied with a bow 🎀</p>

<p>GraphOS is a critical part of our customers’ stack, so reliability is a critical concern for us at Apollo. Our customers need confidence that features like Uplink, the schema registry, and Contracts will be available. For cloud customers who trust Apollo to manage routing infrastructure in the critical path, this is even more important. On the <a href="https://www.apollographql.com/trust/reliability">Reliability page</a>, you can read more about how we approach matters like failovers, backups, and redundancy.</p>

<p>Lastly, we’ve put all paperwork associated with legal and privacy compliance on the <a href="https://www.apollographql.com/trust/legal-and-privacy">Legal page</a>. There, you’ll find information about how Apollo’s legal team helps customers comply with the European Union’s GDPR, California’s Consumer Privacy Act, and more. Working with Apollo means one less scavenger hunt for privacy policies and data processing addendums.</p>

<p>One of the most exciting offshoots of the Trust Center that we’re most excited about is creating new GraphOS security content. Security is one of the most requested topics customers ask us about and we can’t wait to talk about it. So go check out the <a href="https://www.apollographql.com/trust/">Trust Center</a>. Click around, download a security report, and explore. If you’ve got feedback, questions, or suggestions, we’d love to hear from you on the Apollo Community forum.</p>


Introducing the Apollo Trust Center


<p>We’re building so much great stuff at Apollo that it can be tricky to keep track of it all! To help with that, we’re kicking off our Changelog series to cover exciting releases for GraphOS and our open-source projects. We’ll also let you know about upcoming live events and new educational content to help you expand and sharpen your graph expertise. So without further ado, let’s see what’s new!</p>



<h2 class="wp-block-heading"><a href="#boost-app-responsiveness-with-defer-in-graphos" aria-hidden="true" class="aal_anchor" id="boost-app-responsiveness-with-defer-in-graphos"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Boost app responsiveness with @defer in GraphOS</h2>



<p>If a query includes a field that takes a long time to resolve, it can delay your graph’s entire response, making your apps feel less responsive. With GraphOS support for the @defer directive (now generally available!), your graph can respond to the client with most of the response data almost immediately, then follow up with slower fields when they’re ready.</p>



<p>To learn more, check out <a rel="noreferrer noopener" href="https://www.apollographql.com/blog/announcement/platform/rethinking-react-components-with-defer/" target="_blank">the announcement blog post</a> and <a rel="noreferrer noopener" href="https://www.apollographql.com/docs/graphos/routing/defer" target="_blank">the docs</a>. Make sure to set your graph’s federation version to 2.1 or higher in Apollo Studio!</p>

Apollo Changelog: Jan 23, 2023


<p>Since the rise of the frontend framework and the framework wars of the 2010s, we’ve all gotten pretty used to the idea of building single-page apps that load a JavaScript bundle and then send queries to a server dynamically as a user clicks around. The move to single-page apps was driven by the need to create faster, more interactive user experiences.</p>



<p>As with every great innovation, solving one problem just opens your eyes to the next one. As we all settled into the new normal of building apps with UI frameworks, the next major challenge presented itself: data fetching. Over the last 6 years, GraphQL has once again innovated on the frontend developers&#8217; experience, bringing UI-driven API design, automatic state management, strong types, and much more to the world of building interfaces.</p>



<p>And as someone who’s been building apps with GraphQL for a while, there’s one major ergonomic thing that has bothered me all that time: the relationship between queries and component structure. It’s common to create symmetry between the shape of a GraphQL query and the data that’s rendered in a UI component, but up until now, there has been no way to decouple the query itself from the importance of each field it holds. If you want some fields to load faster than others, or you know there’s a slow field and you don’t want your whole query’s response to be held up, you have to split those into multiple queries. This creates a lot of spaghetti code in components; something simple from a UI and schema design perspective just got complicated due to server implementation.</p>



<p>This isn’t a GraphQL problem–we had it with REST too–but GraphQL is uniquely positioned to solve it because we can annotate each field with metadata!</p>



<p><strong>Introducing, <code>@defer</code></strong></p>



<p>&nbsp;<code>@defer</code> is a directive you can add to queries that will tell your server it can respond to this query in multiple parts. Do you know a particular field is slow? Defer it! This means your server can respond with an initial response to your end-user much faster and fill in the rest when it gets there.</p>



<p>For the last several months, we’ve been working to support <code>@defer</code> across the Apollo stack, and today we’re excited to announce full supergraph support for&nbsp;<code>@defer</code> in GraphOS.<em> </em>You don&#8217;t even need to make any changes to your existing GraphQL API to use it, <em>it just works</em>.</p>



<h2 class="wp-block-heading"><a href="#using-defer-with-your-existing-graphql-api" aria-hidden="true" class="aal_anchor" id="using-defer-with-your-existing-graphql-api"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>Using <code>@defer</code> with your existing GraphQL API</strong></h2>



<p>To use <code>@defer</code>, you just need to have a supergraph router between your GraphQL server and your client (even if you only have one GraphQL server that isn’t using Apollo Federation). The easiest way to create a router is to set up a free serverless instance of Apollo Router with <a href="https://apollographql.com/graphos/">Apollo GraphOS</a>. You can also use <a href="https://www.apollographql.com/docs/rover">Rover</a>, the GraphOS CLI, to start up a local instance of the router. <code>@defer</code> can be used on the root <code>Query</code> field and the router will break the query into multiple GraphQL requests. We can test this out using <strong>any</strong> GraphQL endpoint and <code>rover dev</code>.</p>



<p>In this post, we will use the SpaceX API to see how this works. Remember, the SpaceX example <em>does not</em> use Apollo Federation. First, we use the <code>rover dev</code> command to start up a local instance of the router pointing at <a href="https://spacex-production.up.railway.app/">https://spacex-production.up.railway.app/</a>:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-bash">rover dev --name=spacex --url=https://spacex-production.up.railway.app/</code></pre>



<p>Now you can open up <a href="http://localhost:3000">http://localhost:3000</a> and try executing a query using <code>@defer</code> on the root <code>Query</code>:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">query Launches {
  launches {
    id
    details
    rocket {
      rocket_name
    }
  }
  ... @defer {
    deferredLaunchDetails: launches {
      id
      upcoming
    }
  }
}</code></pre>



<p>Notice we&#8217;re aliasing the root query field to isolate a single field. An upgraded query planner instructs the router to fetch the deferred portions of a query:</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="726" height="512" src="https://wp.apollographql.com/wp-content/uploads/2023/01/spacex-defer-queryplan.png" alt="A Query Plan showing two fetch requests to the SpaceX API where one fetch is being deferred" class="wp-image-19235" srcset="https://wp.apollographql.com/wp-content/uploads/2023/01/spacex-defer-queryplan.png 726w, https://wp.apollographql.com/wp-content/uploads/2023/01/spacex-defer-queryplan-300x212.png 300w" sizes="auto, (max-width: 726px) 100vw, 726px" /></figure>



<p>We can see that the generated query plan shows the router breaking our query into two requests to the SpaceX GraphQL API. Now you can <code>@defer</code> any field in your current API without making any changes 🚀</p>



<h2 class="wp-block-heading"><a href="#using-defer-on-any-entity-in-the-supergraph" aria-hidden="true" class="aal_anchor" id="using-defer-on-any-entity-in-the-supergraph"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>Using <code>@defer</code> on any Entity in the supergraph</strong></h2>



<p>When <a href="https://www.apollographql.com/docs/federation/entities/">entities</a> are used in the supergraph, they define an additional execution boundary for the deferred portions of a query with additional benefits like being able to <code>@defer</code> on nested fragments within a single root query.</p>



<p>Entities in the supergraph are traditionally used to split the implementation of an entity into multiple subgraph modules for a better <a href="https://www.apollographql.com/docs/federation/#separation-of-concerns">separation of concerns</a>. The supergraph router can then perform API-side joins by fetching the entity data from individual subgraphs and flattening the results into the requested query shape.</p>



<p>Since the Router uses the existing <a href="https://www.apollographql.com/docs/federation/subgraph-spec/">subgraph specification</a> supported in <a href="https://www.apollographql.com/docs/federation/supported-subgraphs/">over 24 languages and frameworks</a>, app developers can start using <code>@defer</code> in their client queries without any backend changes to existing subgraphs.</p>



<p>In this post, we&#8217;re going to use the <a href="https://github.com/apollographql/hack-the-supergraph">Apollo Hack the Supergraph demo</a> for the hosted subgraphs. We&#8217;ll still use <code>rover dev</code> to try this out. In separate terminal windows, start a rover dev session for these subgraphs:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-bash">rover dev --name=products --url=https://hts-products-production.up.railway.app/

# In a new terminal window
rover dev --name=reviews --url=https://hts-reviews-production.up.railway.app/</code></pre>



<p>Now you can open up <a href="http://localhost:3000">http://localhost:3000</a> and try executing a query using <code>@defer</code> on the product reviews:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-">fragment ProductReviewsFragment on Product {
  reviews {
    content
  }
}

query ExampleQuery {
  products {
    id
    title
    description
    price {
      amount
    }
    ...ProductReviewsFragment @defer
  }
}</code></pre>



<p>You should see the <code>data.products.reviews</code> be deferred in the response and query plan:</p>

<p>The easiest way to get started with the Apollo Router is to <a href="https://www.apollographql.com/docs/graphos/quickstart/cloud">create a serverless instance</a> with <a href="https://studio.apollographql.com/signup?referrer=blog">GraphOS</a>. Once you&#8217;ve added your existing GraphQL API in GraphOS, you&#8217;ll need to be on the latest version of Apollo Client (<a href="https://www.apollographql.com/docs/react/data/defer/">React</a>, <a href="https://www.apollographql.com/docs/kotlin/fetching/defer/">Kotlin</a>, <a href="https://github.com/apollographql/apollo-ios/issues/2395">iOS support coming soon</a>). That&#8217;s it, you can start using <code>@defer</code> in your apps 🎉.</p>

<p>Last week we officially launched Apollo Server 4! AS4 is lightweight and easier to use than any previous iteration of Apollo Server. We are sure that you’ll love it, and we are excited to help you <a href="https://www.apollographql.com/docs/apollo-server/v4/getting-started">get started with it from scratch</a> or <a href="https://www.apollographql.com/docs/apollo-server/migration/">migrate</a> from a previous version.</p>



<p>With Apollo Server 4 now generally available, <strong>Apollo Server versions 2 and 3 are now officially deprecated</strong> and will reach their <strong>final end of life on October 22, 2023</strong>. </p>



<p>Additionally, <strong>the subscriptions, uploads, and Playground features of Apollo Server 2 will have an earlier end-of-life on December 31, 2022</strong>.&nbsp;</p>



<p>Apollo will continue to provide security patches and fixes for major regressions until October 2023, after which Apollo Server 2 and 3 will no longer be maintained by Apollo. <strong>Note:</strong> After December 31, 2022, Apollo will only continue to evaluate security issues and major regressions in Apollo Server 2 that persist with `{ subscriptions: false, playground: false, uploads: false }`.</p>



<p>If you are currently using Apollo Server 2 or 3, you can find details about migrating to Apollo Server 4 in <a href="https://www.apollographql.com/docs/apollo-server/migration">this guide</a>.</p>

Announcing the end-of-life schedule for Apollo Server 2 & 3


<p>With <a href="https://www.apollographql.com/docs/router/">Apollo Router v1.x</a> being rapidly adopted as our next-generation <a href="https://www.apollographql.com/blog/announcement/backend/the-supergraph-a-new-way-to-think-about-graphql/">supergraph</a> runtime and Apollo Gateway v2.x and Federation 2 <a href="https://www.apollographql.com/blog/announcement/backend/apollo-federation-2-is-now-generally-available/">being GA for over 7 months</a>, Apollo Gateway v0.x is now officially <a href="https://www.apollographql.com/docs/resources/product-launch-stages/#deprecated">deprecated</a> and will reach its <a href="https://www.apollographql.com/docs/resources/product-launch-stages/#end-of-life">end-of-life</a> on <strong>September 22, 2023</strong>.<br><br>As of today, <strong>Apollo Gateway v0.x</strong> is no longer under active development. We will, however, continue to release security patches and fixes for major regressions until September 2023, after which Apollo Gateway v0.x will <strong>no longer be supported or maintained by Apollo</strong>.&nbsp;</p>



<p>We recommend <a href="https://www.apollographql.com/docs/router/migrating-from-gateway/">migrating to Apollo Router</a> today for its significant performance gains and capabilities. <a href="https://www.apollographql.com/blog/announcement/backend/announcing-apollo-router-v1-0/"><strong>Apollo Router 1.x</strong></a> is the re-platforming of the Gateway offering <a href="https://www.apollographql.com/blog/announcement/backend/apollo-router-our-graphql-federation-runtime-in-rust/">10x better performance</a>, enhanced security, and many built-in capabilities like cors, logging, telemetry, and traffic shaping that can be <a href="https://www.apollographql.com/docs/router/configuration/overview#yaml-config-file">configured declaratively with YAML</a> rather than with Javascript code. Optionally, the Router can be customized with Rhai scripts and native Rust plugins for advanced use cases. Our roadmap for the router includes new features like entity-based <code>@defer</code> support (now in preview), <a href="https://www.apollographql.com/events/virtual-event/graphql-summit-october-2022/the-future-of-real-time-data-in-graphql/">live queries</a>, authorization, caching, demand control, and much more.</p>



<p>If you are unable to migrate to the Router, <strong>Apollo Gateway 2.x </strong>is a drop-in upgrade from Gateway 0.x. Plugins and middleware written for 0.x will work unmodified in Gateway 2.x. Most future feature development will be focused on Apollo Router, so we would love to understand any obstacles you encounter migrating to it.

Announcing the end-of-life schedule for Apollo Gateway v0.x


<p>Apollo Server 4 is a lightweight, open-source, spec-compliant GraphQL server that’s compatible with any GraphQL client. It’s a great choice for building a production-ready, self-documenting GraphQL API that can use data from any source. You can use Apollo Server 4 as a subgraph in a federated Supergraph or as a stand-alone GraphQL server.</p>



<p>Apollo Server 4 introduces the <code>@apollo/server</code> package which decouples plugins and frameworks from the core of Apollo Server. It offers a stable API for HTTP and serverless frameworks, enabling users to build Apollo Server integrations for their framework of choice. Apollo Server 4 also introduces a TypeScript-first development and documentation experience to help you build typesafe servers using a schema-first development process.</p>



<p>Apollo Server 4 is generally available! You can <a href="https://www.apollographql.com/docs/apollo-server/v4/getting-started">get started from scratch</a> or <a href="https://www.apollographql.com/docs/apollo-server/v4/migration">migrate from an older version</a> today!</p>

<p>A strength and a challenge of the JavaScript/TypeScript ecosystem is how many different options there are available to solve any problem. For example, there are dozens of popular web frameworks to choose between when setting up an HTTP server. There are also many serverless environments like AWS Lambda and Google Cloud Functions that each have their own APIs for handling HTTP requests. We want Apollo Server to work with as many of them as possible.</p>



<p>In previous versions of Apollo Server, there wasn’t a well-defined API layer between the “core” of Apollo Server and the individual framework integrations. Many features of Apollo Server were implemented as logic which had to be repeated in each integration, but often in slightly different, framework-specific ways. Improving any of these features often meant changing framework-specific code in 9 different packages.</p>



<p>For Apollo Server 4, we defined simple portable data structures for HTTP requests and responses, and we rewrote Apollo Server to act on these representations. Apollo Server now has a stable API for building framework integrations, which now usually consist of a dozen or so lines of code that convert between the request and response objects of the framework and Apollo Server. AS4 also has native support for serverless framework lifecycles, and serverless integrations now use a dedicated API during the server startup sequence to execute operations.</p>

<p>The Apollo Server 4 core project ships with a core-maintained integration for the most popular Node web framework (Express) as well as a simple standalone web server for when you don’t need to configure much.&nbsp;</p>



<p>We’ve <a href="https://github.com/apollo-server-integrations">set up infrastructure</a> to help our community build and maintain integrations, such as with <a href="https://github.com/apollo-server-integrations/apollo-server-integration-aws-lambda">AWS Lambda</a>, <a href="https://github.com/apollo-server-integrations/apollo-server-integration-fastify">Fastify</a>, and <a href="https://github.com/apollo-server-integrations/apollo-server-integration-koa">Koa</a>. Community members have also already built integrations with new environments such as <a href="https://github.com/apollo-server-integrations/apollo-server-integration-h3">H3</a> and <a href="https://github.com/apuyou/apollo-server-nextjs">Next.JS</a> that were never before supported by Apollo Server. Because building integrations require less domain-specific implementation, framework experts and integration authors can build integrations for their framework of choice and add those integrations to our <a href="https://github.com/apollo-server-integrations">Apollo Server integrations GitHub organization</a>.</p>



<p>Additionally, because integrations are now maintained independently from Apollo Server, it will be much easier to update your framework to take advantage of new features in your web framework of choice. We are always looking to add new framework integrations, so if you don’t see <a href="https://github.com/apollo-server-integrations">an integration</a> you’d like to use, create an issue on <a href="https://github.com/apollographql/apollo-server/issues">GitHub</a>. If you specialize in any of <a href="https://github.com/apollographql/apollo-server/labels/integration-collaborators">these frameworks</a> and are interested in building or maintaining an AS4 integration, please reach out!</p>

<p>Apollo Server 3 was structured as a large number of distinct packages for each framework integration. For example, Express users used the <code>apollo-server-express</code> package while Fastify users used the <code>apollo-server-fastify</code> package. Other functionality involved depending on one of a wide array of smaller packages, and it was challenging to ensure you used a consistent version across these packages. Apollo Server 4 simplifies this situation by combining all of the core code into a single new <code>@apollo/server</code> package.</p>



<p>Unlike Apollo Server 3, the Apollo Server 4 package is also published in both CJS and ESM formats! The ECMAScript Module format improves upon the CommonJS (CJS) format pioneered by Node. Modern build tools can better optimize packages built as ESM, resulting in reduced bundle size. Smaller, optimized bundles allow serverless runtimes like AWS Lambda to start up faster.&nbsp;</p>



<p>Because AS4 is published in both formats, you get the improved efficiency of ESM if you use a newer build tool without losing compatibility with older build environments that only support CJS.To learn more about the difference between ESM and CJS and their interoperability, check out the <a href="https://nodejs.org/api/esm.html#differences-between-es-modules-and-commonjs">Node.js documentation</a>.</p>

<p>With the release of Apollo Server 4, we’ve updated all of <a href="https://www.apollographql.com/docs/apollo-server/">our documentation</a> to show a TypeScript-first approach and recommend Typescript as the default way to build with Apollo Server.</p>



<p>When using Apollo Server 3, there was no way to specify the type of your context value when setting up your server. This led to typing inconsistencies because there was no compile-time check ensuring the type returned by your context function matched the value in your plugins and resolvers.</p>



<p>Apollo Server 4 enables you to write code that can statically check that your resolver types match their schema types, using a schema-first approach. To do this, Apollo Server documents the use of the <code>graphql-code-generator</code> package with typescript-resolvers to ensure server implementations are type-safe. To get started or learn more about generating types from your schema, check out <a href="https://www.apollographql.com/docs/apollo-server/workflow/generate-types">our documentation</a>.</p>

<p>On Tuesday, Matt DeBergalis, CTO at Apollo GraphQL, kicked us off with a keynote announcing Apollo GraphOS and the new features we are launching. (Read on to learn what we launched at GraphQL Summit.) Attendees then split up across the GraphQL Summit pavilion to join compelling sessions from companies like Netflix, Fidelity, Wayfair, and Pinterest.  Marc-André Giroux from Netflix’s talk on Building Great GraphQL Developer Experiences @ Scale was packed with insight on how Netflix helps build solutions to empower 100s of developers to collaborate on their supergraph.  Attendees also raved about the practical advice for protecting your GraphQL API in Nick Aleks and Dolev Farhi’s talk on Offensive GraphQL Security Testing. Sam Scott from Oso’s talk Authorization Patterns in GraphQL and Ash Narcisse from Apollo’s Root of Auth things talks came in with high remarks from attendees. Tuesday&#8217;s closing keynote, How a Supergraph Powers The Front Page of the Internet, was by Reddit’s Savannah Forood and Jameson Williams. </p>

<p>Tuesday morning, we introduced Apollo GraphOS, a complete cloud platform that lets anyone build, connect, and scale any supergraph. There are three key components of GraphOS:&nbsp;</p>



<ol class="wp-block-list"><li><strong>A global supergraph run-time</strong> that is either hosted by Apollo or Enterprise users can self-host using Apollo Router</li><li><strong>A schema delivery pipeline</strong> that includes a schema registry, observability, and schema validation to prevent downtime</li><li><strong>A supergraph development kit </strong>a set of tools that give you a complete supergraph development environment on your laptop</li></ol>



<p>GraphOS delivers advanced capabilities like @defer out of the box. @defer lets you mark slow parts of your query and tell the graph it can deliver those parts asynchronously, allowing teams to build more responsive, faster experiences.</p>



<p>Summit attendees could test out GraphOS at the supergraph stations across the venue.</p>



<p>Learn more about GraphOS <a href="https://www.apollographql.com/graphos/">here</a>.</p>



<p><strong>Our supergraph development kit&nbsp;</strong></p>



<p>The supergraph development kit is a set of tools that lets you spin up a complete supergraph development environment on your laptop powered by Apollo Router. New Rover templates in popular programming languages allow new teams to onboard to the graph faster, by providing the skeleton for building out subgraphs.</p>

<p><strong>A peek into supergraph linking</strong></p>



<p>In Tuesday&#8217;s keynote, Matt previewed supergraph linking. The supergraph is a powerful way to allow independent teams within an organization to collaborate on a shared API. However, when organizations need to build experiences that require capabilities from other companies, this often results in writing tedious wrapping code around 3rd party APIs. The current approach creates a risk of experiences breaking if any underlying APIs change.&nbsp;</p>



<p>Matt showcased our conceptual approach to linking multiple supergraphs that would allow organizations to share capabilities more efficiently. Martijn Walraven went into more depth during his session, The Future of the Supergraph. He discussed how namespacing, dynamic schema composition, and multi-level routing could be used to build supergraph linking.</p>



<p><strong>Real-time data proposal</strong></p>



<p>For monolithic graphs, subscriptions are the most common approach for providing real-time data to GraphQL clients. However, implementing real-time solutions in federated graphs is challenging. As part of Wednesday&#8217;s opening keynote, Ben Newman, Apollo Open-Source Architect, proposed a real-time data protocol for federated graphs using @live directive and cursor-based query revalidation and diffing.</p>

GraphQL Summit 2022 Recap: Highlights, Product Announcements, and Puppies


<p>As of today, you can now use our new public API to integrate with the Apollo GraphOS platform.</p>



<p>We built this API to enable those using GraphOS to easily automate operations in their own systems and CI workflows. In fact, this is the same API that the <a href="https://www.apollographql.com/docs/rover/">Rover CLI</a> uses to run schema checks and publish schemas to Apollo Studio.</p>



<p>Under the hood, the GraphOS platform API uses schema <a href="https://www.apollographql.com/blog/announcement/platform/contracts-are-now-generally-available/">contracts</a> to make our private platform API publicly available. By creating a contract, we can filter out the necessary subset of our private platform API schema, all the while keeping the public schema in sync with the source.</p>



<p>See the <a href="https://studio.apollographql.com/public/apollo-platform/home?variant=main">API’s readme</a> to get started, and check out the operation collections in Explorer to see example GraphQL queries and mutations you can use for your own graphs.&nbsp;</p>



<h2 class="wp-block-heading"><a href="#take-the-api-for-a-spin" aria-hidden="true" class="aal_anchor" id="take-the-api-for-a-spin"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Take the API for a spin</h2>



<p>So, let’s try it out! We’ve embedded the API’s Explorer from Studio below. (Yes, you can <a href="https://www.apollographql.com/docs/studio/explorer/embed-explorer/">embed the Explorer</a> for any of your graphs managed in Studio!)&nbsp;</p>



<p>Here are some examples of what you can do with the GraphOS platform API:</p>



<ul class="wp-block-list"><li>Retrieve a list of your GraphQL supergraphs</li><li>Fetch a graph for a specific environment (such as staging)</li><li>Publish your supergraph’s schema</li><li>Check your supergraph’s schema for errors</li></ul>



<p>Note: Some of these operations, like publishing a new graph, require that you set your own Studio API key. See the <a href="https://studio.apollographql.com/public/apollo-platform/home?variant=main">readme</a> for instructions.&nbsp;<br>Check out our operations collections and try running some queries, read the API’s inline documentation, or see the <a href="https://studio.apollographql.com/public/apollo-platform/schema/reference?variant=main">schema reference</a> to view all the API’s types and fields:</p>

<p>In most cases, you’ll want to use the Apollo Rover CLI to manage and publish your GraphQL supergraph schema. As developers iterate on their subgraphs, we recommend regularly running schema checks to ensure that their updated graphs properly compose into a supergraph. If you use continuous integration (CI), we recommend integrating Rover into your pipeline. <a href="https://www.apollographql.com/docs/rover/ci-cd">Here’s how to get started</a>.</p>



<p>If you need to do more complex operations, then you might want to use the GraphOS platform API. For instance, you might want your CI pipeline to create a new Studio variant for each test run, then delete that variant when the run finishes. To accomplish this, you can do the following using the Platform API:</p>



<ul class="wp-block-list"><li>Create a test variant by <a href="https://studio.apollographql.com/public/apollo-platform/home?variant=main#publishing-schemas">Publishing your schema(s) to it</a>.</li><li>Perform any desired tests (such as <a href="https://studio.apollographql.com/public/apollo-platform/home?variant=main#running-schema-checks">schema checks</a>) on the test variant.</li><li>Delete the variant with the corresponding <a href="https://studio.apollographql.com/public/apollo-platform/home?variant=main#destructive-actions">destructive action</a>.</li></ul>



<p>In the near future, we will post about other ways to integrate with the GraphOS platform, such as using the platform API with your governance workflows for your supergraphs. We also look forward to learning how you will use the API!</p>

<p>This is just the start for the GraphOS platform API! We are continuing to add new features to both GraphOS and the platform API to make it easier for you to get your schema changes safely to production, to keep your teams up-to-date, and to ensure that clients consuming your graph never experience breaking changes.</p>



<p>To stay up-to-date on what’s coming next with the GraphOS platform API, <a href="https://github.com/apollographql/apollo-studio-community">star and watch the Apollo Studio Community GitHub project</a>. We will be sharing more about the GraphOS platform API roadmap there and here in the Apollo blog.</p>

Integrate with GraphOS using the new Platform API


<p>When we built Apollo in 2016, we had a vision. We set out to build one distributed and scalable data layer that could connect to anything we need, no matter the client, the architecture, the source, the language. It was a lofty goal, but work worth doing, because solving this gets to the heart of how to make app development more approachable and productive.</p>



<p>We realized this vision with <a href="https://www.apollographql.com/blog/announcement/backend/the-supergraph-a-new-way-to-think-about-graphql/">the supergraph</a>, a new layer of the stack that unifies an organization’s data, services, and capabilities, built around three underlying principles: 1) One unified composition layer; 2) Built in modules; 3) That evolves over time.</p>



<p>Today, we’re announcing Apollo GraphOS, a complete cloud platform that lets anyone build, connect, and scale any supergraph. GraphOS is the execution fabric for the supergraph – a powerful runtime that connects backend and frontend systems in a modular way. It also has an integrated control plane to help developers manage, evolve, and collaborate on the supergraph.&nbsp;</p>



<p>GraphOS lets you connect all your data and services seamlessly with federation. It gives you advanced capabilities like <code>@defer</code> without having to write any code or sign up for any ops burden. And it’s secure – we’ve achieved SOC 2 Type 2 compliance, and passed a full audit by Doyensec with flying colors.</p>



<h2 class="wp-block-heading"><a href="#why-graphos" aria-hidden="true" class="aal_anchor" id="why-graphos"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>Why GraphOS?</strong></h2>



<p>We hear a lot from developers that they want to do more with the graph. They want to scale, but they really don’t want to have to think about it. They just want to build products.</p>



<p>We wanted to solve this. Not everyone has a big ops team or the GraphQL expertise or the desire to run infrastructure for the supergraph themselves. They need something that’s easy to start with and that can grow along with them – a supergraph operating system that can scale to any number of subgraphs, across every continent, at lightning speed.</p>



<p>So we built one.</p>



<h2 class="wp-block-heading"><a href="#whats-in-it" aria-hidden="true" class="aal_anchor" id="whats-in-it"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>What’s in it?</strong></h2>



<p>Apollo Router is the heart of GraphOS – built in Rust, designed for performance. We partnered with Fly.io to build our own cloud-based supergraph runtime on top of Apollo Router, designed for exactly what the supergraph needs. It gives us the global reach of an edge network with the core computing capability and performance to support new and upcoming features like query planning, @defer, live queries, and so much more to come.</p>



<p>We paired this global supergraph runtime with our complete set of schema delivery, collaboration, and observability tools so developers can publish changes to the supergraph and seamlessly deliver them across all their apps. And, last but not least, we included a supergraph development kit that can connect any existing graph to the supergraph.&nbsp;</p>



<h2 class="wp-block-heading"><a href="#our-supergraph-development-kit" aria-hidden="true" class="aal_anchor" id="our-supergraph-development-kit"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>Our supergraph development kit&nbsp;</strong></h2>



<p>We hear from thousands of GraphQL developers that there is a disconnect between how they start building graphs, and how they scale them. That disconnect leads to breaking changes, bloated schemas, and uncertainty about the path forward.</p>



<p>If we have learned one thing about graphs, it is that they MUST mature, change, and adapt. The supergraph doesn’t work if it requires a rewrite of the entire existing system. It’s not the v2 of a schema. It’s about modularizing what already exists –&nbsp; transforming an existing graph into a module and elevating it into a full-fledged supergraph.</p>



<p>What if you could take what you’ve already built, and say: ok this isn’t the end. This is just my first module. Where can I go from here? What else can I build from here?&nbsp;</p>



<p>Let’s add a new service; a new function.&nbsp;</p>



<p>And another.&nbsp;</p>



<p>And another.&nbsp;</p>



<p>All individual and unique, each written in whatever language I choose, each independent and flexible. But all connected.&nbsp;</p>



<p>The supergraph development kit is here to make this all possible with three components that create a seamless developer experience:</p>



<ul class="wp-block-list">
<li><strong><code>rover dev</code>:</strong> Spins up a supergraph and runtime locally, making the graph you have your first module.</li>



<li><strong><code>rover template use</code>:</strong> Gives anyone access to a cookbook of templates for adding new modules in all the most popular languages and frameworks.&nbsp;</li>



<li><strong>Sandbox:</strong> A GraphQL IDE designed for local supergraph development and testing.</li>

<ul class="wp-block-list"><li>As teams think about creating or migrating their APIs to Apollo Federation, it can be perplexing, if not paralyzing, to decide where functionality should go in a distributed system. In this session, Fidelity Investments share the techniques that have helped us identify and separate functionality, using time-tested engineering techniques, including domain-driven design, that teams can embrace to become productive faster.</li></ul>



<p><span style="text-decoration: underline;">State of the Federation Subgraph Ecosystem</span> with Derek Kuc, Principle Engineer, Apollo GraphQL </p>



<ul class="wp-block-list"><li>Apollo Federation is a powerful, open architecture that helps you create a unified supergraph that combines multiple GraphQL APIs. From dynamically typed languages like JavaScript to statically typed Java. From functional programming style of Elixir to Object Oriented one in C#. SDL first or code first. Developers have a number of options to choose from when developing their GraphQL subgraphs. In this talk we’ll explore the ever growing federation subgraph ecosystem and highlight some of the available libraries.</li></ul>

<ul class="wp-block-list"><li>Remove the stress and guess work from designing your company&#8217;s large GraphQL schema. Having an intensive schema design process ensures your graph remains consistent and coherent but often blocks product teams from meeting deadlines due to complex ownership issues and required time for a quality design review. Instead, learn how to unblock your product teams and let them express what they want from the graph by allowing them to create whatever schema they want exactly how they want it in their own protected bubble on the supergraph. Learn from the schemas your client applications are creating and design a quality shared schema at the pace required to do the job properly.</li></ul>

The Graph Architect’s Guide to GraphQL Summit 2022


<p>For federated graph variants, Apollo offers schema checks to ensure that proposed changes to subgraphs won’t break supergraph composition (build checks) or your active clients (operation checks).&nbsp;</p>



<p>Today, we’re excited to extend this capability to <a href="https://www.apollographql.com/blog/announcement/platform/contracts-are-now-generally-available/">contracts</a>!</p>



<h2 class="wp-block-heading"><a href="#what-are-contract-checks" aria-hidden="true" class="aal_anchor" id="what-are-contract-checks"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>What are contract checks?</h2>



<p>Contract checks ensure that changes made to a source variant’s subgraphs or to the contract filtering configuration won’t cause breaking changes to any downstream contract variant’s schema or active clients. Each contract check runs two types of tasks to do this:</p>



<ol class="wp-block-list"><li><strong>Build tasks</strong>: Build tasks verify that downstream contract variants build successfully and that filtering rules continue to work as expected.</li><li><strong>Operation tasks:</strong> Operation tasks check proposed schema changes against historical operations to the contract variant (and any other selected variant) to verify whether the changes will break any of the contract variant’s active clients.</li></ol>



<h2 class="wp-block-heading"><a href="#how-are-contract-checks-triggered" aria-hidden="true" class="aal_anchor" id="how-are-contract-checks-triggered"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>How are contract checks triggered?</h2>



<p>Contract checks are triggered in two scenarios:&nbsp;</p>



<p><strong>1. Changes are made to the source variant’s subgraphs and source variants checks are run</strong></p>



<p>When a source variant has downstream contracts associated with it, Apollo will run an additional task in the checks workflow called a <strong>downstream task</strong>.&nbsp;</p>



<p>When a change is made to any of the source variant’s subgraphs, the checks workflow begins, and the downstream task runs contract checks for all of the downstream contract variants.</p>

<p><strong>2. Contract filter configuration is edited in Studio</strong></p>



<p>When you edit the filtering configuration for a contract in Studio, contract checks will run to make sure that the new filter rules can apply without build errors and without causing breaking changes that affect operations from the contract variant’s active clients.&nbsp;</p>



<p>If any checks fail, you’ll see a warning when reviewing the new contract schema, but you can still choose to update the contract even if there are warning or if checks haven’t finished running.</p>

<p>Contracts checks are available today on Apollo’s Enterprise plan! Head over to checks configuration in Studio to select which contract variants should be blocking your source variant checks to fail. If you aren’t on Apollo Enterprise and would like to try it out, <a href="https://www.apollographql.com/contact-sales/">talk to us</a> about an Enterprise trial.</p>



<p>ℹ️ If you are using the Rover CLI to run checks in your CI/CD pipelines, you must upgrade to at least Rover v0.8.2 to get the best and full functionality of contract checks. If you are using Rover v0.8.0 or v0.8.1, your source variants that have associated contract variants <em>will</em> start triggering contract checks as described above, however, if a contract check fails, it won’t cause <code>rover subgraph check</code> to fail, affecting the accuracy of your CI/CD pipeline.</p>



<p>⚠️ <strong>Note: </strong>Please make sure you are on the latest version of the Studio UI. Click on the bell icon at the top right corner of Studio and if you see <em>“Update available, click to relaunch”</em> at the bottom left of the modal then click that to get the latest version.</p>


Prevent breaking changes in downstream variants with contract checks


<p>A healthy graph is never still — new features appear, old ones are pruned, and regretful decisions are repaired (“at last, my schema is perfect” &#8211; said no one ever).</p>



<p>But planning for change requires graph maintainers to tread carefully &#8211; the more you know about how your schema is being used, the more confidently and quickly you can move. With the new Field Insights page in Apollo Studio, safe and rapid innovation of your graph just got a whole lot easier.</p>

<h3 class="wp-block-heading"><a href="#fields-as-features" aria-hidden="true" class="aal_anchor" id="fields-as-features"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Fields as <em>features</em></h3>



<p>Fields are the last stop for querying data from the graph. They represent the atoms of information that are exposed to the outside world. They are also functions &#8211; when used in a mutation, they are the entry points that trigger actions in the graph. Every field is literally a “feature” of the graph, and if we want to measure the usage or health of our graph’s features, the field is a great place to start. Maintaining a graph comes with a mindset of continuous curation, and knowing where to focus our improvements is key.</p>



<h3 class="wp-block-heading"><a href="#fields-as-relationships" aria-hidden="true" class="aal_anchor" id="fields-as-relationships"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Fields as <em>relationships</em></h3>



<p>Crucially, fields also model the relationships that bind objects together. This is what makes GraphQL uniquely powerful — queries can move freely about the graph, jumping from one entity to the next and fetching as much or as little data as they need along the way. But if one of these links breaks down, entire subtrees can go dark. This is of special concern in a federated context where fields provide the bridge between the business domains in your API.</p>

<p>Viewing usage data through the lens of your fields unlocks some essential graph health workflows. With field insights, we are bringing these capabilities into focus for your graph:</p>



<ol class="wp-block-list"><li><strong>Understand usage and adoption patterns.</strong> Client usage breakdowns make it easy to see how client applications and operations are using the field, and field usage over time tells you whether field usage is ramping up or down.</li><li><strong>Identify impact on user-facing apps.</strong> Understand earlier in the schema lifecycle the changes that are likely to impact end-users and other team members based on observed usage.</li><li><strong>Guide change workflows</strong>. Confidently deprecate and remove outdated or unused fields. See the first and last time a field was used, then verify changes with <a href="https://www.apollographql.com/docs/studio/schema-checks">schema checks</a> at release time.</li><li><strong>Assess field-level health.</strong> Per-field error rates and latency histograms help you pinpoint health issues in your graph to target optimization work and validate improvements.</li><li><strong>Understand federation dependencies.</strong> Discover which subgraphs participate in resolving a field as teams work together to build the graph. (Hint: use the <code>@contact</code> directive in your subgraphs to let teams know how to get in touch with one another!)</li></ol>

<p>The amazing flexibility of GraphQL has been game-changing for app developers, but it does present an observability challenge. With operations of all shapes and sizes, how can we best understand which parts of the graph are being used, how much, and by whom? What parts of the schema are unhealthy or causing performance bottlenecks for the graph? With the new Field Insights page, you’ll have a powerful new tool to answer these kinds of questions.</p>



<p>Field Insights are available to all organizations, with longer data retention offered on paid Apollo plans. As always, we’d <a href="https://docs.google.com/forms/d/1lC-7aWNe4pnxcAPTB-W4-N8jZoyD_xQXzVByD6HOZpc/edit">love your feedback</a> on how we could further improve your graph workflows.</p>

<p>Challenges of Modularizing a GraphQL iOS Application Calvin Cestari, iOS Engineer, Apollo GraphQL</p>



<ul class="wp-block-list"><li>There is no one-size-fits-all approach to building a modularized iOS app. How would you approach sharing generated GraphQL schema objects throughout your modularized app? Do you want to co-locate the generated model objects with the rest of your view code? How could you share GraphQL fragment generated code with multiple objects and/or operations? This talk explores a few of the challenges you might face, and some techniques for resolving them.</li></ul>



<p>Navigating the Normalized Cache Ali Asghari, Staff Engineer, Wayfair</p>



<ul class="wp-block-list"><li>Mobile app experiences focus as much on the space between screens as they do the screens themselves. Transitioning between screens however is data bounded, often requiring a latent network round trips to fully render. While pre-fetching is a solution, for apps with federated ownership, coordinating what data to pre-fetch becomes challenging. By examining what motivates our users’ navigational patterns, we can design schemas which allow for uncoordinated data sharing and smoother transitions by leveraging the normalized cache.</li></ul>



<p>Schema Updates on Mobile GraphQL Clients Anthony Miller, Lead Developer, Apollo iOS, Apollo GraphQL&nbsp;</p>



<ul class="wp-block-list"><li>Most GraphQL clients use schema knowledge to execute GraphQL operations, configure caching, generate model objects, and more. This talk explores the problems that schema updates pose to mobile applications using Apollo iOS and Apollo Kotlin; some methods for dealing with those problems; and how possible future additions to the GraphQL specification could help mitigate them.</li></ul>



<p>Isolated Client Development with Kaitlyn Taboada, Lead Software Engineer, Odeko</p>



<ul class="wp-block-list"><li>We will cover using the power of the schema to create meaningful/reliable stub data quickly. This allows frontend developer work without relying on backends to be complete or operational. This is vital for a microservice ecosystem to prevent users from needing to spin up microservices to develop locally.</li></ul>

Apollo introduces  supergraph professional services by Xolvio


<p>We’re excited to announce that Apollo is now SOC 2 Type II certified, an incredibly important milestone for us that demonstrates the investment we’ve put into building a safe and secure product and organization over the years.&nbsp;</p>



<p>SOC 2 Type II certification is a third-party audit that’s part of the American Institute of CPA’s (AICPA) <a href="https://us.aicpa.org/interestareas/frc/assuranceadvisoryservices/aicpasoc2report">Service Organization Control reporting platform</a>. It’s a necessity for any cloud SaaS business today. In order to achieve SOC 2 compliance, companies like Apollo must undergo a rigorous audit of the security policies and controls it has in place to protect its customers’ data. This certification means that Apollo has written – and operates our business – based on a set of comprehensive information security policies and procedures.</p>



<p>You can request a copy of our Type II audit through your customer success team.</p>

<p>One of our core company values is empowering others –&nbsp;setting people up, both inside and outside the company, to do their best work. This certification demonstrates that value by letting our customers know that every bit of information they put into their supergraph is being handled safely and securely. We will continue to focus on, and extend our commitment to security so that,&nbsp;as more and more companies use the supergraph to power the world&#8217;s most important apps, they will know Apollo takes their data security seriously.</p>


Apollo earns SOC 2 Type II compliance


<p>Two years ago we set out to build Apollo Explorer &#8211; the GraphQL IDE we felt was missing from the GraphQL community. And last summer, we made Explorer available for local development by releasing it in <a href="https://www.apollographql.com/blog/announcement/platform/apollo-sandbox-an-open-graphql-ide-for-local-development/">Apollo Sandbox</a>. But Sandbox still ran on the Apollo Studio domain, and our #1 challenge has been distributing Explorer in a way that gives you enough control over the network properties of your queries. Authentication, CORS, firewalls, you name it – a GraphQL IDE exists to let people write queries, and graph admins need to be able to control the network properties of those HTTP requests, full stop.</p>



<p>We added a lot of controls to Explorer to help. We made a way for graph admins to set default headers on their graphs. We built a mechanism for you to define preflight scripts which can do things like automatically refresh tokens in the headers on your graph. But in the end, we have found that there’s no setting we can add to Studio that can replace what <strong>you</strong> can do with full control over the network requests from our IDE.</p>



<p><strong>That’s why today we are giving Sandbox to <em>you</em>.&nbsp;</strong></p>



<p>We are over the moon to share with you that we have made Apollo Sandbox available for you to <strong>embed on any website</strong>, not just on Apollo Studio. ✨🌙 ✨</p>

&lt;script&gt;
 new window.EmbeddedSandbox({
   target: &quot;#sandbox&quot;,
   // Pass through your server href if you are embedding on an endpoint.
   // Otherwise, you can pass whatever endpoint you want Sandbox to start up with here.
   initialEndpoint: window.location.href,

<p>We know there are a number of GraphQL IDEs to pick from these days&#8230; and we know we’re biased, but we’re particularly excited to bring Sandbox to you because it’s so much more than just an IDE.</p>

<p>Over the years, we’ve met many developers who have told us they were scared to restart their computer or clear their browser cookies because they didn’t want to lose their queries in GraphiQL/Playground.</p>



<p>It’s 2022, and we figured that it’s about time for that to be a problem of the past. 🕰️</p>



<p>Connect your local Sandbox to your Studio account to <strong>save operations in the cloud</strong> and never worry about losing your work again.</p>

<p>Have you ever worked with a schema so large it was distributed across multiple files or maybe even multiple repos? What about a GraphQL server that generates its schema from code and doesn’t even have an SDL file?</p>



<p>When developing graphs, sometimes all you want is a simple schema diff. But due to the implementation details of our graphs, that’s not always easy to accomplish. So we built it right into Sandbox.</p>



<p>You can diff your local schema against any graph in Apollo Studio, and if the changes look good, you can even run <a href="https://www.apollographql.com/docs/studio/schema-checks">schema checks</a> from Sandbox to make sure they pass CI before checking them into code.</p>

<p>One of the best properties of GraphQL is that it’s self-documenting. We’ve always felt like squashing graph docs alongside a query IDE just didn’t do enough justice to the act of exploring the graph or referencing something in particular. That’s why we built a full-fledged automatic schema reference tool in Studio.</p>



<p>Sandbox also comes with Studio’s schema reference tool:</p>

<p>And of course, Sandbox has the Apollo Explorer and every feature we’ve built into it over the last several years.<a href="https://www.apollographql.com/docs/studio/explorer/explorer"> Explorer</a> is by far the most sophisticated GraphQL IDE in the ecosystem.</p>



<p>We love Explorer so much because it’s not just a playground for you to query graphs, it’s a playground for us as developers to build the things we always felt were missing from GraphQL tooling. As developers, there’s so much power we’ve gotten used to having in our IDEs and the GraphQL DX is still catching up in a lot of ways. We get new ideas every week about how to improve the Explorer just from using it ourselves.</p>



<p>Explorer has become a passion project of ours, and it is our expression of love for the GraphQL DX itself.</p>

<p><strong>That’s all for now folks!</strong></p>



<p>We’re very happy to be bringing this to you today. It’s the culmination of a couple of years of dreaming within the Apollo zoom tunnels, now turned into reality. We’d love to see what you do with Sandbox and where you take your graphs. ❤️</p>

How to use Apollo Sandbox on your localhost


<p><strong>Embed private graphs, use embeds to invite new users, and use improved Apollo Client Dev Tools.</strong></p>



<p>Explorer is an incredible GraphQL IDE that makes it quick and easy to browse schemas and run operations against them. It’s so awesome, that our community asked us to make it embeddable so that it could be used anywhere – and last year, <a href="https://www.apollographql.com/blog/announcement/platform/embed-apollo-explorer-anywhere/">we did just that</a>! But at the time, you could only embed public graph variants. Now, we are happy to announce that you can embed Explorer on <strong>any website</strong> with <strong>any graph variant</strong> – even private variants!&nbsp;</p>



<p>You can provide the experience of Explorer on any of your internal or external documentation, dev portals, and websites to onboard new consumers to your graphs.</p>

<p>💡Embedded Explorer uses the graph ref from Apollo Studio. Since your graph is registered in Studio, embedded Explorer is always kept up to date with the schema changes in Studio. You can take your schema anywhere by embedding Explorer while Studio’s registry acts as its single source of truth behind the scenes. How neat is that?!</p>

<p>If the graph variant you want to embed isn’t public (meaning it’s gated behind Studio authentication), then the embedded Explorer will request the visitor to authorize access before proceeding.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1425" height="861" src="https://wp.apollographql.com/wp-content/uploads/2022/06/image2.gif" alt="" class="wp-image-14021"/></figure>



<p>If the visitor has never interacted with Apollo Studio before &#8211; no problem! They can sign up and be invited from the embed itself.</p>



<p>If your Studio org is using SSO, users are invited with the role that is default selected for your org.&nbsp;</p>



<p>Otherwise, while copying the embed code from the modal in Apollo Studio, admins can configure whether they would like to invite visitors to the organization and select the role to invite with.</p>

Improved embedding for Apollo Explorer!


<p>We’ve had a busy month at Apollo. Over the last several weeks we’ve released some significant updates to the Apollo stack. Last month we shipped <a href="https://www.apollographql.com/blog/announcement/backend/apollo-federation-2-is-now-generally-available/">Federation 2</a>, a sophisticated and more flexible approach to GraphQL composition. And last week we made <a href="https://www.apollographql.com/blog/announcement/platform/contracts-are-now-generally-available/">Contracts</a> generally available, a way to tailor your graph to specific use cases like mobile development or creating public GraphQL APIs.</p>



<p>Today we’re launching updates to two more components of our stack: the <a href="https://apollographql.com/blog/apollo-router-is-now-generally-available">GA release of Apollo Router</a> – our new high-performance runtime for federated GraphQL APIs – and a <a href="https://apollographql.com/blog/schema-checks-and-launches-are-now-available-for-free-in-apollo-studio/">new cloud-hosted build pipeline</a> for delivering changes to a graph.</p>



<p>We’ve been building these tools together to help teams implement a more advanced GraphQL architecture – one that delivers essential capabilities for operating mission-critical graphs in organizations with many teams, programming languages, and technologies. That architecture is now at the heart of API strategy at companies like Netflix, Walmart, Expedia, Zillow, RetailMeNot, Paypal, Major League Baseball, and many more.&nbsp;</p>



<p>We think it’s time to give this architecture a name, and after talking about it with the developers that have pioneered this approach in their companies, we’re calling it <strong>the supergraph</strong>.</p>



<h2 class="wp-block-heading"><a href="#the-principles-of-supergraph-architecture" aria-hidden="true" class="aal_anchor" id="the-principles-of-supergraph-architecture"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>The principles of supergraph architecture</h2>



<p>The essential ideas of the supergraph are going to be <a href="https://principledgraphql.com/">pretty familiar to those who’ve been following Apollo for a while</a>. It comes down to three core principles.</p>



<h3 class="wp-block-heading"><a href="#1-a-unified-composition-layer" aria-hidden="true" class="aal_anchor" id="1-a-unified-composition-layer"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>1: a unified composition layer</h3>



<p>The supergraph is a new way to think about implementing GraphQL that goes far beyond the technical benefits of replacing data fetching and BFF code with schema and queries. It’s a unified network of a company’s data, microservices, and digital capabilities that serves as the “composition layer” for the whole organization.&nbsp;</p>



<p>The supergraph empowers everyone to create richer, more engaging experiences for their users and customers by bringing everything into a single point of collaboration.</p>



<h3 class="wp-block-heading"><a href="#2-a-modular-architecture" aria-hidden="true" class="aal_anchor" id="2-a-modular-architecture"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>2: a modular architecture</h3>



<p>Supergraph architecture is declarative and modular. Just as React and Kubernetes leverage modularity to scale UI development and service deployment, the supergraph leverages modularity to scale the API layer as it grows beyond a single team.&nbsp;</p>



<p>Apollo Federation has always been about bringing modularity to the API layer – letting you scale a graph without bottlenecking developers on a single monolith or creating a single point of failure.&nbsp;</p>



<p>Of course, Apollo Federation offers a lot of additional advantages along the way: programmable configuration, standardized tooling, analyzable query plans, strict validation at build-time instead of run-time, great support for heterogeneous environments, a structured on-ramp for new developers, and many more.</p>



<h3 class="wp-block-heading"><a href="#3-an-agile-approach" aria-hidden="true" class="aal_anchor" id="3-an-agile-approach"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>3: an agile approach</h3>



<p>The supergraph enables an agile bottom-up approach. Traditionally, APIs tend to be fairly static. Because it’s so hard to change an API, the tendency is to waterfall a design that anticipates future requirements. But products change constantly, driven by evolving user requirements and feedback.&nbsp;</p>



<p>The supergraph works harmoniously with rapidly changing products because it empowers developers to ship schema changes swiftly and safely to support their own initiatives, causing the schema to naturally evolve based on actual usage and the needs of the business.</p>



<h2 class="wp-block-heading"><a href="#on-to-the-supergraph" aria-hidden="true" class="aal_anchor" id="on-to-the-supergraph"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>On to the supergraph</h2>



<p>We’ve seen case after case of the supergraph architecture – a unified layer, made from modules, continuously evolving – emerging organically at companies we respect and admire. So we’re focused on this idea of the supergraph and our ambition is to help every team have one. Here’s how all that we’ve been building helps with that goal.</p>

<p>Apollo Federation is our open specification for composing subgraphs – modular GraphQL services – together into a single supergraph. Each subgraph is a self-contained component with its own schema and server, so it can be developed, tested, and deployed independently.&nbsp;</p>



<p>Rather than relying on custom code to combine subgraphs, subgraphs reference and extend each other through a principled set of primitives. Thanks to our incredible developer community, Federation supports subgraphs written in over <a href="https://www.apollographql.com/docs/federation/other-servers">20 programming languages</a> and a growing number of GraphQL-native services and products.</p>



<p><a href="https://www.apollographql.com/blog/announcement/backend/apollo-federation-2-is-now-generally-available/">Federation 2</a> builds on what we’ve learned from our community. It adds more complete support for the GraphQL spec including interfaces and new directives which can eliminate much of the boilerplate code that came with Federation 1.&nbsp;</p>



<p>Federation 2 also streamlines cross-team collaboration with a flexible shared ownership model that allows multiple subgraphs to implement overlapping, complementary parts of types and schemas. New governance directives like <code>@inaccessible</code>, <code>@shareable</code>, and <code>@override</code> give teams fine-grained control over the composition process and resulting supergraph schema.</p>



<p>TLDR; Apollo Federation is now more approachable and incrementally adoptable for anyone interested in building a supergraph, and it scales seamlessly all the way into enterprises with thousands of developers collaborating on the largest rapidly-evolving supergraphs. Check out <a href="https://www.apollographql.com/docs/federation/quickstart/setup/">the Federation quickstart</a> to learn more.</p>

At a minimum, the runtime for a supergraph has to receive client requests, build an execution plan, route requests to the proper subgraphs, assemble the results back together, and return it back to the client. We launched Apollo Gateway — an add-on to Apollo Server — alongside Apollo Federation to serve this purpose, but we quickly realized that we needed to build a more elegant solution that was purpose-built for the task. We decided to call it a <strong>graph router</strong>.</p>



<p>A graph router does far more than a traditional API gateway. Like a relational database, it requires a sophisticated implementation that shields users from unwanted details of execution while still providing a principled way to analyze and control the system when necessary. Critical infrastructure like this is better written in a lower-level systems language that offers a smaller operational footprint, so we opted for Rust instead of Node.js.</p>



<p>At the end of 2021, we released the world’s first and only graph router: Apollo Router. The performance advantages are significant: Apollo Router processes requests with <strong>10x lower latency</strong>, <strong>10x higher throughput</strong>, and <strong>12x lower variance</strong> compared to Apollo Gateway, its JavaScript predecessor. Take a look at the benchmark below to get a sense of how much better it is.</p>

<p>GraphOS Studio is the final piece of the puzzle for building and operating a supergraph. Its delivery pipeline provides the validation, automation, and observability you need to deliver changes rapidly and safely, making it possible to constantly evolve the supergraph schema, particularly when teams leverage and extend each other’s contributions.</p>



<p><a href="https://www.apollographql.com/docs/studio/schema-checks">Schema Checks</a> and <a href="https://www.apollographql.com/docs/studio/launches">Launches</a> prevent breaking changes before they happen by automatically validating your supergraph schema in development and giving visibility into past and in-progress changes to the supergraph.</p>



<p>Previously only available on our Enterprise plan, <a href="https://apollographql.com/blog/schema-checks-and-launches-are-now-available-for-free-in-apollo-studio/">today we are making Studio’s delivery pipeline available to everyone</a>.</p>

<p>We’re excited to get the core components of the supergraph architecture in your hands. We can’t wait to build with you and we are eager to work together on what’s next.</p>


The supergraph: a new way to think about GraphQL


<p>Apollo Router, the next-generation runtime for our <a href="https://apollographql.com/blog/the-supergraph-a-new-way-to-think-about-graphql">supergraph stack</a>, is here, and it’s fully production-ready.&nbsp;</p>



<p>It’s been about six months since we first unveiled Apollo Router at GraphQL Summit. Since then, we’ve been improving it and testing it to ensure that it’s even more efficient, secure, reliable, and customizable. And today, we’re excited to make Apollo Router generally available.</p>

<p>Apollo Router is a supergraph runtime written in Rust that supports <a href="https://apollographql.com/docs/federation/v2">Apollo Federation</a> (v1 or v2) &#8211; a declarative GraphQL architecture that lets you build and collaborate on a unified GraphQL API (a supergraph) in a modular and declarative way. The router is what processes all of the incoming API requests from clients and <em>routes</em> them to the subgraphs that make up the overall supergraph.</p>

<p>You may be thinking, “doesn’t Apollo Gateway already do that?” It does! Apollo Gateway is our Node.js supergraph runtime, and we will continue to support it well into 2023 and likely beyond. But when it comes to routing API requests, speed is the name of the game, and Apollo Router is FAST ⚡️.</p>



<p>In our benchmarks Apollo Router processed requests <strong>10x faster</strong> than Apollo Gateway with<strong> 10x higher throughput</strong> and <strong>90% less variance in latency</strong>. And that’s just the start. We have more improvements coming up on the roadmap that will make it even more efficient.</p>

<p>Apollo Router is easier to manage. Unlike Apollo Gateway, Apollo Router ships as a standalone binary. To use it, you simply download and run it with any valid supergraph schema. This makes containerization and scaling a breeze! We even supply <a href="https://www.apollographql.com/docs/router/containerization/overview">Docker images</a> for every release.</p>

Apollo Router is now generally available


<p>Today, we’re updating Apollo Studio to make its <a href="https://apollographql.com/blog/the-supergraph-a-new-way-to-think-about-graphql">supergraph</a> delivery pipeline, including <a href="https://www.apollographql.com/docs/studio/schema-checks">Schema Checks</a> and <a href="https://www.apollographql.com/docs/studio/launches">Launches</a>, available for anyone to use for free.</p>



<p>We’ve made a lot of exciting announcements about supergraphs recently. In April, we announced the <a href="https://apollographql.com/blog/apollo-federation-2-is-now-generally-available/">general availability of Federation 2</a>, an improved version of Federation that makes it easier for anyone to build a supergraph. And just today, we announced <a href="https://apollographql.com/blog/apollo-router-is-now-generally-available">general availability of Apollo Router</a>, our next generation supergraph runtime written in Rust. </p>



<p>With Federation and Router, anyone can build and run a supergraph. But the needs of your users evolve rapidly, and like any other layer of your stack, your supergraph needs to evolve with them. That’s where Apollo Studio comes in.</p>



<h2 class="wp-block-heading"><a href="#optimized-for-iteration-the-supergraph-delivery-pipeline" aria-hidden="true" class="aal_anchor" id="optimized-for-iteration-the-supergraph-delivery-pipeline"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Optimized for iteration: the supergraph delivery pipeline</h2>



<p>The days of lockstep deployments are over. Teams need the ability to deploy changes many times a day without worrying about breaking production.&nbsp;</p>



<p>We built Apollo Studio’s delivery pipeline to help you evolve and iterate on your supergraph schema with speed and confidence. It’s a single source of truth that provides the automation, validation, and observability you need to deliver changes rapidly and safely. After building a supergraph and adopting a Studio’s delivery pipeline, <a href="http://apollographql.com/customers/retailmenot">RetailMeNot</a> saw a 7X reduction in time spent deploying schema changes and eliminated production outages. Schema Checks and Launches are two core delivery features that make this possible.</p>



<h3 class="wp-block-heading"><a href="#schema-checks" aria-hidden="true" class="aal_anchor" id="schema-checks"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Schema checks</h3>



<p>Schema checks validate changes to your supergraph schema so that you can be confident that it&#8217;s ready for production. There are two types of schema checks that Apollo Studio runs for supergraphs: composition checks and operation checks.</p>



<p>Composition checks validate that subgraphs compose successfully into the overall Supergraph schema. If composition succeeds, operation checks then validate that your composed supergraph schema will serve all of your client applications by checking it against historical operations on your supergraph.</p>

<p>The best part: schema checks can be run within existing CI/CD tools using Apollo’s Rover CLI to create a seamless integration with your existing software delivery pipelines.</p>

<p>One of the fantastic benefits of GraphQL that a supergraph inherits is that it’s versionless. But even without a version, it’s still extremely important to understand how your supergraph has evolved over time and if new changes are live. Launches in Apollo Studio are how you do that.</p>



<p>Launches give you a way to reason about the lifecycle of your supergraph. In Apollo Studio, a launch represents the complete process of an update to your deployed supergraph running through Studio’s delivery pipeline. An update to your supergraph could include:</p>



<ul class="wp-block-list"><li>Adding, removing, or modifying types and fields in a subgraph schema</li><li>Adding or removing entire subgraphs</li><li>Migrating types or fields between subgraphs</li></ul>



<p>The Launches page in Apollo Studio gives you visibility into in-progress and past launches for your supergraph. It’s a dashboard that summarizes how launches over time have evolved your supergraph, helping you track when new changes are reflected in production and debug when something goes wrong.</p>

Schema Checks and Launches are now available for free in Apollo Studio


<p>At GraphQL Summit last year, we announced the <a href="https://www.apollographql.com/blog/announcement/platform/introducing-contracts-serve-many-audiences-with-a-unified-graph/">preview release of Contracts</a> on Apollo’s Enterprise plan. Contracts allow you to create tailored graphs for different audiences by applying filters to a single unified graph. Today, we are excited to announce that Contracts are generally available!</p>



<h2 class="wp-block-heading"><a href="#one-graph-many-representations" aria-hidden="true" class="aal_anchor" id="one-graph-many-representations"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>One graph &#8211; many representations</strong></h2>



<p>Building a unified graph is incredibly beneficial. It gives you a single source of truth for all your organization’s data, services, and business capabilities and allows developers to deliver better, faster apps with less overhead. However, unification can introduce new challenges at scale:</p>



<ul class="wp-block-list"><li>How do you create varying levels of access for different personas or types of users like customers, employees, suppliers, or partners?</li><li>How do you provide partners and public API users with a schema scoped for their integration and app development needs?</li><li>How do you maintain client-specific BFFs and experience-driven schemas alongside a canonical domain-driven schema?</li><li>How do you restrict access to experimental or non-stable parts of the graph, but still allow access for testing and early adopters?</li></ul>



<p>In summary, <strong>“how do I serve multiple different audiences with a single graph?”</strong> The answer: <strong>Contracts</strong>!</p>



<p>Using Contracts, you can take your unified graph and create filtered variants of that graph that contain only a subset of its types and fields. Contracts can power separate graphs for partner developers, specific client applications, public APIs, experimental features, and more without losing any of the benefits of the unified graph.</p>

If you have migrated your graph variants to Federation 2, you can now create contracts from them.&nbsp;</p>



<p>Additionally, if your graph variants are on Federation 2, you can hide additional schema elements like input arguments, input types and fields and enums, which is currently not possible with Federation 1. </p>

<p>We have also added the ability to see a <em>before</em> and <em>after</em> view of your contract schema once you have applied your filter configurations. This will allow you to quickly verify the changes you are making against the source variant schema or latest successful contract schema.&nbsp;</p>



<p>When creating or updating a contract schema, you can click on Generate Preview to see the number of types and fields the proposed contract schema will have. You can also see any errors that occur when generating the contract schema with the selected filter configuration.</p>

<p>Contracts are generally available today on Apollo’s Enterprise plan! To learn how to create your first contract, check out our documentation.</p>



<p>To get the most out of Contracts, we recommend migrating your source variants (from which contracts schemas are created) to Federation 2. Federation 1 supports Contracts as well, but it does not support tagging of input and enum types and fields.</p>



<p>If you aren’t on Apollo Enterprise and would like to try it out, <a href="https://www.apollographql.com/contact-sales/">talk to us</a> about an Enterprise trial.</p>



<p><strong>⚠️ Note:</strong> Make sure you are on the latest version of the UI. Click on the bell icon at the top right corner of Studio and if you see “Update available, click to relaunch” at the bottom left of the modal then click that to get the latest version.</p>



<p><em>(Contracts are patent pending)</em></p>


Contracts are now generally available


<p>The momentum continues to build around Apollo Federation with over 1M weekly downloads and 18K+ projects now using Apollo Federation, up 50% in the last 5 months since <a href="https://www.apollographql.com/blog/announcement/backend/announcing-federation-2/">Federation 2 was first announced</a>.&nbsp;</p>



<p>We’d like to extend a big thank you to our community! Because of your contributions, Federation developers can compose subgraphs written in <a href="https://www.apollographql.com/docs/federation/v2/other-servers">over 18 languages and frameworks</a>!</p>



<p><strong>Today, we’re excited to announce the general availability of Apollo Federation 2, with improvements across the entire Apollo platform including Gateway 2.0, the Rover CLI, and Apollo Studio.</strong>&nbsp;</p>



<p>Keep reading to learn more about Federation and what you can expect from the new improvements in Federation 2 or head to our docs to <a href="https://www.apollographql.com/docs/federation/v2/">get started today</a>! 🚀</p>

<p>Apollo Federation is a <a href="https://www.apollographql.com/docs/federation/v2">modular GraphQL architecture</a> that powers the world’s most important graphs, including <a href="https://netflixtechblog.com/how-netflix-scales-its-api-with-graphql-federation-part-2-bbe71aaec44a">Netflix</a>, <a href="https://medium.com/walmartglobaltech/federated-graphql-walmart-bfc85c2553de">Walmart</a>, <a href="https://medium.com/adobetech/graphql-making-sense-of-enterprise-microservices-for-the-ui-46fc8f5a5301">Adobe</a>, and <a href="https://www.apollographql.com/docs/federation/enterprise-guide/federation-case-studies/">more</a>.&nbsp;</p>



<p>Designed in collaboration with the GraphQL community, Federation 2 is a clean-sheet implementation of the core composition and query-planning engine at the heart of Apollo Federation.&nbsp;</p>



<p>The new version builds on the success of the original with an improved shared ownership model, enhanced type merging, and cleaner syntax for a smoother developer experience. It’s backward compatible and designed for incremental adoption one subgraph at a time.</p>

<p>Apollo Federation’s shared ownership model lets you spread a federated type across subgraphs so that you can reuse common value types like interfaces and enums. Federation 2 improves upon the shared ownership model and makes shared types more flexible:</p>



<p><strong>Value type definitions are now merged into a single unified type</strong>. Value types don’t need to be identical across subgraphs, so smaller incremental changes, like adding a field, can often be rolled out one subgraph at a time by using the <code>@inaccessible</code> directive to hide it from the client-facing schema.</p>



<p><strong>All types are shared equally across subgraphs</strong>. This means you don’t have to use the <code>extend</code> keyword.</p>



<p><strong>All fields have a single source of truth by default. </strong>You can optionally mark a field or object with the <code>@shareable</code> directive&nbsp; so other subgraphs can resolve them, which may increase performance.</p>

<p>As the shape of your subgraphs change, sometimes fields need to be migrated from one subgraph to another. This previously required a coordinated release across subgraphs to avoid downtime. </p>



<p>With Federation 2, field migration is painless. Simply add the field to the destination subgraph, mark it with <code>@override</code> to accept production traffic without downtime, and remove the migrated field from the old subgraph.</p>

<p>Federation 2 has deeper static analysis, better error messages, and a new generalized composition model that helps you catch more errors at build-time instead of at runtime. The rewritten composition engine now validates all theoretically possible queries and provides more descriptive error messages when a query can’t be satisfied. New composition hints help you understand how schema definitions influence query planning and performance.</p>

<p>While Federation 2 is backwards compatible, its enhanced validation might <a href="https://www.apollographql.com/docs/federation/v2/federation-2/backward-compatibility#breaking-changes">catch a few things</a> that the original Federation didn’t. Things you’ll be happy to know about!</p>

<p>⚠️ <strong>Note: The Apollo Contracts preview does not yet support Federation 2. If you are using Contracts in production you should not upgrade to Federation 2 yet. The generally available release of Contracts will include support for Federation 2.</strong></p>



<p>Moving to Federation 2 is a simple and incremental process:</p>



<ol class="wp-block-list"><li><strong>Upgrade your Gateways to version 2.0.0 or later.</strong> Gateway 2 is backward compatible with Federation 1 and any existing customizations you have, so this won’t break anything.</li><li><strong>Turn on Federation 2 composition</strong> for the Rover CLI and Apollo Studio. Federation 2 composition will automatically convert Federation 1 subgraphs, so you can get some great benefits (like improved error messages) without upgrading any subgraphs! 🎉</li><li><strong>Upgrade individual subgraphs to Federation 2 syntax at your own pace</strong>. Because Federation 2 composition is backward compatible with Federation 1 subgraphs, you can add Federation 2 syntax to your subgraphs at your own pace.</li></ol>

Apollo Federation 2 is now generally available


<p>At last year’s GraphQL Summit we announced the alpha release of <a href="https://www.apollographql.com/blog/announcement/backend/apollo-router-our-graphql-federation-runtime-in-rust/">Apollo Router</a> for the first time &#8211; our new, high-performance Federation runtime written in Rust. Today, we’re excited to bring Apollo Router out of Alpha and into an open preview!</p>

<p>You may be wondering, “how do I get started with Apollo Router?” Good news! Unlike Apollo Gateway, Apollo Router is a standalone binary that’s purpose-built for running federated schemas, so it’s easy to deploy and scale. There are just three steps to get started:</p>



<ol class="wp-block-list"><li>Download Apollo Router</li><li>Make sure your project has a supergraph schema</li><li>Run Apollo Router 🚀</li></ol>



<p>It’s that easy! For the full quickstart guide including downloads and detailed instructions, check out <a href="https://www.apollographql.com/docs/router/">our docs</a>.</p>

<p>Using our example is a great way to get started, but if you’ve ever run a supergraph in production with Apollo Gateway, you may have encountered a&nbsp; common challenge: how do you extend your gateway to meet your specific needs. The Gateway has a well-documented extensibility model, but you need to know node.js to take full advantage of it.</p>



<p>With Apollo Router, we want to make extensibility more approachable, which is why plugins can be configured with just a `router.yaml` file. Apollo Router is written in Rust, but things like propagating headers to subgraphs and OpenTelemetry can be configured with the `router.yaml` file without writing any Rust code, with more plugins coming soon.</p>



<p>However, we know that not every use case can be covered with pre-built customizations, so Router also supports lightweight <a href="https://www.apollographql.com/docs/router/customizations/rhai">Rhai scripting</a>. When YAML configuration is insufficient, Rhai scripting allows you to make programmatic customizations without requiring you to recompile the router with a custom Rust plugin.</p>

<p>Operation Collections are a new, <strong>free</strong> feature in Apollo Studio that help you save and organize operations in folders that align to different use cases, client apps, personas and more.&nbsp;</p>



<p>Saving your operations into a collection in Explorer means that you and your team can:</p>



<ul class="wp-block-list"><li>Stop writing the same operation over and over</li><li>Organize common operations by how they&#8217;re used and who uses them</li><li>Design, execute, and share operations all in a single interface</li><li>More easily onboard new team members</li></ul>

<p>A collection created as Shared for a graph/variant is automatically visible to every member of the Studio organization who has access to that graph/variant. Shared collections are editable by any graph or org admin. Optionally, editing settings can also be given to other roles in the org.&nbsp;</p>



<p>⚠️ <strong>Note:</strong> If you are an enterprise user, you can configure granular <a href="https://www.apollographql.com/docs/studio/org/members/">role</a> level permissions, otherwise you can choose whether you want to grant edit permissions to all org users.</p>

<p>But that’s not it! Here are a few ways to make it even easier for your team to find shared operations:</p>



<h3 class="wp-block-heading"><a href="#1-share-a-link" aria-hidden="true" class="aal_anchor" id="1-share-a-link"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>1. Share a link</strong></h3>



<p>You can also give team members a link directly to a particular shared collection or operation. To do so, click the <code>•••</code> button next to any shared collection or operation in the list and select the Copy Link option.</p>

Embed in your graph’s README</strong></h3>



<p>Have you added a README for your graph yet? If not, no better time like the present! We added the <a href="https://www.apollographql.com/blog/announcement/platform/create-a-readme-to-onboard-developers-to-the-graph/">README page</a> last year to make it easy for graph producers to onboard new developers on their graphs.&nbsp;</p>



<p>Now you can embed saved operations and collections directly into your README:</p>



<ol class="wp-block-list"><li>Click on the edit icon on the README.&nbsp;</li><li>Using the graph shortcodes, select a saved operation or a collection to embed.&nbsp;</li><li>Check out the preview to make sure everything looks good, and then click Update.</li><li>Tada! 🎉 With a few clicks you’ve added an example set of operations to the README.&nbsp;</li></ol>



<p>Now any developer looking to explore the graph can get started right away!</p>

Create a collection for a public graph</strong></h3>



<p>If you have a <a href="https://www.apollographql.com/blog/announcement/tooling/make-your-graphql-schema-publicly-visible-without-introspection/">public graph</a>, you can publish a collection of example operations to help developers accessing the public graph onboard quickly. Any developer accessing the public graph can view and execute operations in a public collection, without having to login!&nbsp;</p>



<p>⚠️ <strong>Note:</strong> Unauthenticated users do not have edit access for collections</p>

<p>Now you might be thinking, “this is great! But I use Sandbox for my local development. Can I save my operations in collections in Sandbox too?” <strong>Yes you can!</strong></p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1999" height="1024" src="https://wp.apollographql.com/wp-content/uploads/2022/03/image7.png" alt="" class="wp-image-12704" srcset="https://wp.apollographql.com/wp-content/uploads/2022/03/image7.png 1999w, https://wp.apollographql.com/wp-content/uploads/2022/03/image7-300x154.png 300w, https://wp.apollographql.com/wp-content/uploads/2022/03/image7-1024x525.png 1024w, https://wp.apollographql.com/wp-content/uploads/2022/03/image7-768x393.png 768w, https://wp.apollographql.com/wp-content/uploads/2022/03/image7-1536x787.png 1536w, https://wp.apollographql.com/wp-content/uploads/2022/03/image7-1200x615.png 1200w, https://wp.apollographql.com/wp-content/uploads/2022/03/image7-1980x1014.png 1980w" sizes="auto, (max-width: 1999px) 100vw, 1999px" /></figure>



<p>In fact, not only can you save operations in collections across all of your Sandbox endpoints, you can also access collections for any registered graph that you have access to! That means that when you’re using Sandbox to build or make changes to a registered graph in Apollo Studio, you can test out operations in collections for the registered graph and edit them directly as you are making your schema changes!</p>

<hr class="wp-block-separator"/>



<p>Four months ago we announced Apollo Federation 2 &#8211; the next generation of Federation with <a href="https://www.apollographql.com/blog/announcement/backend/announcing-federation-2/">new features</a> designed to improve the graph developer experience and make it easy for anyone to build, manage, and scale a unified graph. </p>



<p>Since then, we’ve been collecting feedback from members of the community and our customers that have tried out the alpha release and have been iterating on the Federation 2 spec to make it viable for the larger GraphQL ecosystem.&nbsp;</p>



<p>With the improvements we’ve made in recent months, we’re excited to move <a href="https://www.apollographql.com/docs/federation/v2/">Federation 2</a> along with <a href="https://www.apollographql.com/docs/federation/v2/gateway/">Apollo Gateway 2.0</a> out of alpha into public preview!</p>

<p>With Federation 2 and Gateway 2.0 now in preview, here are some highlights and improvements to be aware of:</p>



<ul class="wp-block-list"><li>There are <strong>no breaking changes</strong> between Federation 2 alpha and preview.</li><li>Apollo Gateway 0.X does not support Federation 2. If you would like to use Apollo Gateway with Federation 2, you must use Gateway 2.0 or higher.</li><li>Graphs in Apollo Studio with Federation 2 composition enabled will automatically be updated from <code>alpha</code> to <code>preview</code>.</li><li>If you have Federation 2 composition enabled, Federation 1 subgraphs will automatically be converted to Federation 2 during composition. You can continue to use your Federation 1 subgraphs as long as you like.</li><li><code>@link</code> and <code>@shareable</code> are now supported in the Fed 2 subgraph syntax.</li><li><code>subgraph-js</code> subgraph library now supports Fed 2 subgraph syntax.</li></ul>

<h3 class="wp-block-heading"><a href="#1-upgrade-apollo-gateway" aria-hidden="true" class="aal_anchor" id="1-upgrade-apollo-gateway"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>1. Upgrade <code>@apollo/gateway</code></h3>



<p>To use Federation 2, you must be using Gateway 2.0 or higher (or <a href="https://www.apollographql.com/blog/announcement/backend/apollo-router-our-graphql-federation-runtime-in-rust/">Apollo Router</a>). Upgrading from Gateway 0.X to Gateway 2.0 is as easy as bumping the version in your <code>package.json</code>.</p>



<p>Gateway 2.0 is still compatible with Federation 1, so you can upgrade without breaking your existing graph.</p>



<h3 class="wp-block-heading"><a href="#2-turn-on-federation-2-composition" aria-hidden="true" class="aal_anchor" id="2-turn-on-federation-2-composition"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>2. Turn on Federation 2 composition</h3>



<p>Once your runtime is compatible with Federation 2, you’ll need to take a moment to turn on Fed 2 composition for Managed Federation or for the Rover CLI, depending on how you compose your federated graph.</p>



<p>Federation 2 composition is backward compatible with Federation 1 subgraphs (🎉), so turning it on won’t break your existing graph.</p>



<p><strong>Managed Federation</strong></p>



<p>If you use managed Federation, you can turn on Fed 2 composition for specific variants. Navigate to the “Manage Variants” section of your graph’s settings page and click the meatball menu next to a variant.</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh5.googleusercontent.com/qfapzHPkVsn7KDhBrs-x-CRWPT1yLOiu5BzS3krUHAXpC489sApWL5jqf4F64vbc79HMR1AQPnrpECb3-63vTRgt_baqGdHr-1yy6zRbl6majExI73FaiiBif4o63_wZWOwj4vsZ" alt=""/></figure>



<p>Click “Edit Build Configuration” and select Federation 2 under the “Federation Version” dropdown.</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh4.googleusercontent.com/cTbU2CnbeZa_gWjO7QkZ4Phh3o97axRZCBAcazYIaidBBkExnwACRqTGtSgXiWYwg829jE4UM-lQiVk0NOnnk_QYwswQJq_Wh5b5QUEXycbCE9ISYs8Scfp4pAdHd4cPbMe7NZ-Z" alt=""/></figure>



<p><strong>Rover CLI</strong></p>



<p>If you use the Rover CLI for Federation composition, you’ll need to install the latest version of Rover and install the Federation 2 plugin. You can find detailed instructions on how to do so <a href="https://www.apollographql.com/docs/federation/v2/federation-2/moving-to-federation-2/#using-the-rover-cli">here</a>.</p>

Modify your subgraphs at your own pace</h3>



<p>At this point, your graph is already running on Federation 2 &#8211; congrats! Now, to make the most out of Fed 2, you’ll want to modify your subgraphs to take advantage of its more flexible composition model.&nbsp;</p>



<p>Since Fed 2 composition is backwards compatible with Fed 1 subgraphs, service teams can modify their subgraphs at their own pace without breaking composition! You can learn about all of the improvements available in the Fed 2 subgraph syntax in the <a href="https://www.apollographql.com/docs/federation/v2/federation-2/new-in-federation-2/#more-flexible-composition">documentation</a>.</p>

Apollo Federation 2 and Gateway 2.0 are now available in preview


<p>Today we’re excited to show off some recent upgrades to Operation Insights in Apollo Studio. This update features three significant enhancements which make it easier to understand the usage and data flow of operations in your graph.</p>



<h2 class="wp-block-heading"><a href="#1-what-does-an-operation-look-like" aria-hidden="true" class="aal_anchor" id="1-what-does-an-operation-look-like"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>1. What does an operation look like?</h2>



<p>First, we brought the operation signature front and center so that you can quickly understand the shape of fields being requested by the operation.  The signature now appears as a side-panel that you can resize instead of hidden behind another tab.</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="621" src="https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-1-1024x621.png" alt="" class="wp-image-12391" srcset="https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-1-1024x621.png 1024w, https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-1-300x182.png 300w, https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-1-768x465.png 768w, https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-1-1536x931.png 1536w, https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-1-1200x727.png 1200w, https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-1.png 1650w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption>Easier to find operation signatures.</figcaption></figure>

Which subgraphs are used by an operation?</h2>



<p>In the same panel, we added the ability to view the federation query plan for an operation.  The query plan lets you see how Apollo Gateway or Router is working under the hood, describing how data from your subgraphs is woven together to build a full query response.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1024" height="768" src="https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-2.png" alt="" class="wp-image-12397" srcset="https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-2.png 1024w, https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-2-300x225.png 300w, https://wp.apollographql.com/wp-content/uploads/2022/03/operation-blog-2-768x576.png 768w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /><figcaption>See query plans and subgraph dependencies for federated operations.</figcaption></figure>



<p>Similar to features found in Apollo Explorer, you can view the query plan as either a text document or visualized as a tree of subgraphs. (<span class="has-inline-color has-accent-color">Only available to federated graphs.

Which clients are using this operation?</h2>



<p>Last but not least, we introduced a way to understand which clients are using an operation in a new Client Usage display. The most active clients are sorted to the top of the list based on the number of requests reported to Apollo Studio via <a href="https://www.apollographql.com/docs/studio/metrics/usage-reporting/">usage reporting</a>.</p>

New Operation Insights with Client Usage and Federation Query Plans


<p>When you’re a developer working on a federated graph, you likely work on a single subgraph locally before publishing it to Apollo Studio as part of the supergraph. We created <a href="https://www.apollographql.com/blog/announcement/platform/apollo-sandbox-an-open-graphql-ide-for-local-development/">Apollo Sandbox</a> to give developers a great tool for working on locally-running graphs, but wouldn’t it be great if could get the same functionality when working with subgraphs? And even better &#8211; what if you could use Sandbox to run checks to check that your local changes won’t break composition or operations against the federated graph? Well, now you can!</p>

<p>When working off a subgraph, head over to <a href="http://studio.apollographql.com/sandbox/">Apollo Sandbox</a> and connect to your subgraph localhost via the Sandbox endpoint field (or you can connect to a remote endpoint if you like). You will notice that a <code>SUBGRAPH</code> badge appears next to the endpoint. Your subgraph schema is loaded and ready to be queried!&nbsp;</p>



<p>Explore your subgraph schema on the Schema page and run operations in Explorer. As you make changes to your subgraph schema, changes are automatically updated in Sandbox without any manual refresh.</p>

<p>You can ensure that your changes won’t break the supergraph schema composition and or affect any operations to the federated graph by clicking on the “Run a check” button in the loaded diff view or by heading over to the checks tab. If all of your checks pass, you can publish your changes to the registered schema in Apollo Studio with complete confidence!</p>



<p>If you want to see even more details about checks, you can navigate to the main checks page on Studio. You can always move back and forth between Sandbox and full Studio experience using the box icon on the top right corner in the navigation bar.</p>



<p><strong>⚠️</strong> <strong>Note:</strong> For checks to work, you’ll need to have a Studio account with access to Checks, which is available on Team and Enterprise plans only.</p>

Introducing subgraph support in Apollo Sandbox


<p>Since releasing <a href="https://www.apollographql.com/blog/announcement/platform/introducing-contracts-serve-many-audiences-with-a-unified-graph/">contracts</a> as a way to serve many audiences with a unified graph, we’ve received great feedback from developers adopting contracts and championing the graph. However, one question we frequently hear is: “how can I reason about contracts with respect to my publishing pipeline?”</p>



<p>As of today, we are thrilled to introduce Contract Launches in Apollo Studio to answer this very question. With Contract Launches, you can use the Launches page in Studio that provides better visibility into the lifecycle of your contract schemas and helps you understand which contracts launched from a given source variant.</p>

<p>Every contract is built from an existing source variant. Publishing updates to your source variant triggers downstream launches for any contract built from that source.</p>



<p>Let&#8217;s look in more detail what this looks like:</p>



<ol class="wp-block-list"><li>You publish an update to your source variant</li><li>A launch initiates for the source variant</li><li>If the launch was successful a core schema is the output artifact</li><li>The core schema is then approved and made available to gateways</li><li>A launch for each contract is initiated<ol><li>The core schema is used as the build input to contract launches</li></ol></li><li>The schema is then filtered into a contract schema</li><li>If the launch was successful a contract schema is the output artifact</li><li>The contract schema is then approved and made available to gateways</li></ol>

<p>For any launch that triggers a contract launch, you can see a summary of how many downstream launches succeeded or failed:</p>

<p>You can also take a look at the Launch Sequence to see the status of each contract launch individually. To debug a failed launch, you can navigate to the Launches page for a contract by clicking the desired contract launch item.</p>



<p>A contract launch that completes successfully is made available to running gateways via Uplink.</p>



<p>⚠️ <strong>Note:</strong> Checks for contracts are not currently supported but are in active research and development.</p>

<p>Apollo Contracts is currently in public preview on Apollo’s Enterprise plan. Feedback from our community and customers is crucial to the success of Apollo, and the feedback we’ve received from pilot users so far has been instrumental in ensuring that contracts can serve many use cases while still giving teams full visibility and control over changes.</p>

Introducing Contract Launches: see the lifecycle of contract schemas in Apollo Studio


<p>We recently introduced Preflight Scripts to Explorer! With preflight scripts you can automatically run any custom authentication before your GraphQL operation is executed. Preflight scripts are especially useful for managing authentication flows like OAuth by refreshing an access token, for example. Let’s take a look.</p>

<p>As you develop your script in the script editor panel, you can click “Test script” to test its execution. Console messages are printed in the Console output panel. Setting any <a href="https://www.apollographql.com/docs/studio/explorer/connecting-authenticating/#environment-variables">environment variables</a> in the above dialog will also be reflected in Explorer. Once you are ready, click Save and the script will be available to all team members executing operations against this graph variant in Explorer.</p>



<p>Below is an example of a preflight script that refreshes access tokens after a specific period of time. </p>



<p>⚠️ <strong>Note:</strong> This script exactly as is will not work since it is using a dummy OAuth server.</p>



<pre class="wp-block-code"><code>if (new Date().getTime() &gt; explorer.environment.get(&quot;token_expires_at&quot;)) {
  const { access_token, expires_at, refresh_token } = await explorer.fetch(
      &quot;https://example.com/token&quot;,
      {
        method: &quot;POST&quot;,
        header: {
            &quot;Content-Type&quot;: &quot;application/json&quot;,
            //...
        },
        body: JSON.stringify({
            refreshToken: explorer.environment.get(&quot;refresh_token&quot;),
        }),
      },
    )
    .then((response) =&gt; response.json());

  explorer.environment.set(&quot;token&quot;, access_token);
  explorer.environment.set(&quot;refresh_token&quot;, refresh_token);
  explorer.environment.set(&quot;token_expires_at&quot;, expires_at);
}</code></pre>



<p>Additionally, we will need to perform the following steps:</p>



<ol class="wp-block-list"><li>Authenticate server outside of Apollo Studio to retrieve token, refresh_token and token_expires_at.</li><li>Add these values as environment variables in Explorer.</li><li>Now, with the preflight script running, when the token expires the script will automatically refresh the token and there is no need to manually authenticate again.</li></ol>

Automatically Authenticate with Preflight Scripts in Apollo Studio Explorer

Introducing Apollo Kotlin


<p>When you’re making changes to your GraphQL schema, you probably make those changes locally before you publish them to a graph registry like Apollo Studio. </p>



<p>We created <a href="https://www.apollographql.com/blog/announcement/platform/apollo-sandbox-an-open-graphql-ide-for-local-development/">Apollo Sandbox</a> so that you can use the best GraphQL IDE when working locally, but wouldn’t it be great if you could easily see the diff between your local schema and the existing schema in Studio? </p>



<p>And even better &#8211; what if you could run checks to see if your local changes could break operations against the production graph? Well, now you can do both right from Apollo Sandbox! Let’s take a look at how:</p>



<h2 class="wp-block-heading"><a href="#validate-your-schema-changes-before-publishing-them-to-studio" aria-hidden="true" class="aal_anchor" id="validate-your-schema-changes-before-publishing-them-to-studio"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Validate your schema changes before publishing them to Studio!</h2>



<p>Want to feel confident about your schema changes before publishing them to Studio? Simply head over to <a href="http://studio.apollographql.com/sandbox/">Apollo Sandbox</a> and connect to your localhost via the Sandbox endpoint field (or you can connect to a remote endpoint if you like).</p>

<p>Go to the Diffs tab and sign into Studio to select a registered graph to diff your local schema against and explore your diff! See a summary of how many types and fields have been added or removed and select to view it as a line wrap if needed.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="1434" height="829" src="https://wp.apollographql.com/wp-content/uploads/2021/12/image4.gif" alt="" class="wp-image-11510"/></figure>

<p>Try running an operation check on your local schema by either:</p>



<ol class="wp-block-list"><li>Using the Run check button from the loaded diff view or</li><li>Going to the Checks tab and selecting a registered graph to check against</li></ol>



<p>Once you see a summary of results, you can also view more details by navigating to the main checks page on Studio.</p>



<p>Remember, you can always move back and forth between Sandbox and the full Studio experience by clicking the box icon in the top righthand corner in the navigation bar.</p>



<p>⚠️ <strong>Note:</strong> For checks to work, you’ll need to have a Studio account with a registered graph that is receiving traffic and access to Checks, which is available on Team and Enterprise plans only.</p>

How to run diffs and operation checks in Apollo Sandbox


<p>The Apollo Studio Explorer is an incredible GraphQL IDE that makes it quick and easy to browse schemas and run operations against them. But wouldn’t it be awesome if you could embed the Explorer into external pages so that you could use it inside your product documentation, internal wiki, or blog post? Now you can! Let’s take a look at how.&nbsp;</p>



<h2 class="wp-block-heading"><a href="#make-the-graph-you-want-to-embed-publicly-visible" aria-hidden="true" class="aal_anchor" id="make-the-graph-you-want-to-embed-publicly-visible"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Make the graph you want to embed publicly visible</h2>



<p>Making your graph publicly visible is as easy as flipping a switch. Simply navigate to the Settings page for your graph in Apollo Studio and under the Access tab, set a variant of your choosing as “public.” That particular variant of your graph is now publicly visible in Apollo Studio! When a variant of a graph is set to public, anyone can navigate to the public Studio URL for that variant and access the README, schema reference, changelog, and Explorer (this is equivalent to <a href="https://www.apollographql.com/blog/announcement/platform/sharing-your-graph-just-got-a-whole-lot-easier-announcing-unlimited-consumer-seats/">Consumer-level access</a>).&nbsp;</p>

<p>Now that your graph is public, head over to Explorer for that graph. If you would like to embed Explorer with a default operation, enter the operation in the editor pane in Explorer before copying the embed snippet (also, maybe test it out first to make sure it works 😄). Then click on the meatball menu right of your operation and click on “Embed this operation.” You can also find the action to embed under the Explorer Settings tab in Explorer.&nbsp;&nbsp;</p>

<p>In the embed modal, you can also toggle any configuration options that you would like such as embedded Explorer with dark theme and keeping the docs panel closed by default. Once you have configured it to your liking, copy the code snippet to embed!</p>

Embed Apollo Explorer Anywhere


<p>GraphQL Summit welcomed more than 10,000 developers and engineering leaders virtually on November 10 &amp; 11 for two days of sessions, panels, and workshops. New for the fall Summit, attendees could choose from two session tracks (Build and Scale) on Day 1. The Build Track offered best practices for building, testing, and maintaining GraphQL.

GraphQL Summit Recap: Everything We Launched

Apollo Router: our GraphQL Federation runtime in Rust


<p>At Apollo, we talk a lot about building a unified graph, and for good reason. A unified graph provides incredible benefits &#8211; a single source of truth for all services, faster apps, faster delivery, less maintenance overhead, and more.&nbsp;</p>



<p>But unification introduces new challenges, especially at scale;</p>



<p><em>“How do I support different experiences and levels of access for different personas or types of users like customers, employees, suppliers, and partners?”</em></p>



<p><em>“How do I provide my partners and public API users with a schema scoped for their integration and app development needs?”</em></p>



<p><em>“How do I provide client-specific BFFs and experience-driven schemas alongside a canonical domain-driven schema?”</em></p>



<p><em>“How do I restrict access to experimental or non-stable parts of the schema, but still allow access for testing and early adopters?”</em></p>



<p>These common challenges boil down to one question: <strong>“how do I serve multiple different audiences with a single unified graph?”</strong> Today, we’re excited to announce Contracts, a new feature in preview on Apollo’s Enterprise plan that allows you to create tailored graphs for different audiences by applying filters to a single unified graph.</p>



<h2 class="wp-block-heading"><a href="#modularity-when-consuming-the-graph" aria-hidden="true" class="aal_anchor" id="modularity-when-consuming-the-graph"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Modularity when consuming the graph</h2>



<p>We often discuss consolidating APIs, but there are benefits to separation as well. Separate APIs can be managed by independent backend teams with less coordination. They can also be tailored to whoever will be consuming them and individually governed for granular access control.&nbsp;</p>



<p>We want to unify our services into a single graph to reduce manual API maintenance and improve delivery velocity, but we don’t want to lose the benefits of separate APIs. Apollo Federation accomplishes this for the backend by modularizing the graph into subgraphs that can be modified asynchronously, allowing service teams to build a unified graph while still operating independently. Contracts deliver the same modularity for the frontend.</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh4.googleusercontent.com/C7ycR2cyk5VACxMpjCNerLEc4vf7VgJlPe8HArwSnkw8RTSMxaZkfjKdvoYHTpOCND1DUuDOnzsCArDtat1hoaD7TCOxmauJG5aTiAGLFH0LEWKG3w8lAl63TdeVwO8Fceh46D86" alt=""/></figure>



<p>With Contracts, graph platform teams can create tailored experiences for multiple audiences by creating contract graphs that contain a filtered subset of the unified graph. Each contract can align with a particular developer audience to streamline the graph experience, rather than providing the entire graph to every internal and external developer. </p>



<p>Using contracts you can create separate graphs for partner developers, specific client applications, public APIs, experimental features, and more without losing any of the benefits of the unified graph.</p>

<p>Contracts work with a simple but powerful new <code>@tag</code> directive which you can apply to fields, interfaces, objects, and unions in your subgraph schemas. You then create filter rules which include or exclude certain tags. Anything not included in the contract will be removed from the client-facing schema for that contract but will still be included in the internal supergraph schema to be used for Federation and routing.</p>

<p>There are two ways you can use a contract schema &#8211; as documentation or as a running endpoint.&nbsp;</p>



<h3 class="wp-block-heading"><a href="#documentation-contracts" aria-hidden="true" class="aal_anchor" id="documentation-contracts"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Documentation contracts</h3>



<p>You might use a contract schema just for documentation if you simply want to streamline the graph experience for internal developers by only showing them the fields they need from the graph. For example, you could create a mobile contract schema that only includes parts of the graph that are relevant to mobile developers and removes unnecessary parts that may only be useful for web or IoT applications.&nbsp;</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh3.googleusercontent.com/y_CGjvKlyyQzkjf26IxM_asEz_wQt-q0nmHnVYohm86YXqsK494uYMGicqDzQlCrpC86NSXs_JbTwtRQTdrUjYHAvsA9vcPzQIbG2uQunP8AkUl65-92ckPVJz1dFBriVy2Nga0I" alt=""/><figcaption><meta charset="utf-8"><em>Documentation contract</em></figcaption></figure>



<p>With Apollo Studio you can point consumers at the tailored contract schema so that they get the full Studio experience with a changelog, comprehensive schema reference, and interactive Explorer scoped to the relevant subset of the graph.</p>



<h3 class="wp-block-heading"><a href="#deployed-contracts" aria-hidden="true" class="aal_anchor" id="deployed-contracts"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>Deployed contracts</h3>



<p>There may be times, however, when we want to restrict not only what appears in the documentation, but also what can actually be queried by a particular audience. To accomplish this, we can deploy a dedicated Apollo Gateway or Router to run the contract schema as a separate endpoint.&nbsp;</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh5.googleusercontent.com/CFHUa0cKxHz4zBzLtWflZm6Fx8vkGAK5Ma4ueehqJX9dQUEzqC3T5POt84Y9zN_6xTDsHEYHDA61mBM1JbYqIxw8ZtxbjNKcP6nCVLZ1oW2qM4UtPsSgmRa229YQeFY4GNMUiQGl" alt=""/><figcaption><em>Deployed contract</em></figcaption></figure>



<p>Developers accessing the deployed contract endpoint will only be able to query parts of the graph that exist in the contract schema and will encounter an error if they try to query for fields that are not included in the contract. This can be particularly useful for building endpoints for external partners or for a public-facing API.</p>

<p>BFFs and other customized APIs for different audiences are fantastic for providing a streamlined developer experience, but they also create overhead for whoever maintains them. One of the best things about contracts is that they automatically remain up-to-date without any manual work when combined with Apollo Managed Federation.</p>



<figure class="wp-block-image"><img decoding="async" src="https://lh3.googleusercontent.com/Y8eIp6JgHd123W0MoVL_Odzun7AVC4iST_ajRRz1bVoIANjAfmvXCm_Tn71-WJscA-YXHvVbDr9UN50fWnDGTXWRn-CfsfJT9qNQdc9lxGoEDlRKPzpEKL1a_ugBIOs3VadAp2xB" alt=""/></figure>



<p>With Managed Federation in Apollo Studio, independent backend service teams publish subgraph schema updates into Apollo, including any tags to be used for contracts. The subgraph schemas are composed together into a supergraph schema which is then used to power a graph router like the Apollo Gateway or Apollo Router. Using the included tags, contract filters are run on the unified supergraph schema automatically deriving subset contract schemas.</p>

<p>It&#8217;s been amazing to see the momentum grow around Apollo Federation with over 1M weekly downloads and 12K+ projects using Apollo Federation. Thanks to community contributions, the thriving ecosystem around Apollo Federation means you can federate subgraphs written in <a href="https://www.apollographql.com/docs/federation/other-servers/">over 12 languages</a> and frameworks.</p>



<p>Originally <a href="https://www.apollographql.com/blog/announcement/apollo-federation-f260cf525d21/">released in 2019</a>, Federation powers some of the largest graphs in the world, including <a href="https://netflixtechblog.com/how-netflix-scales-its-api-with-graphql-federation-part-2-bbe71aaec44a">Netflix</a>, <a href="https://medium.com/walmartglobaltech/federated-graphql-walmart-bfc85c2553de">Walmart</a>, <a href="https://engineering.ziffmedia.com/retailmenot-graphql-federation-3bb36dac5aaa">RetailMeNot</a>, and <a href="https://medium.com/paypal-tech/graphql-at-paypal-an-adoption-story-b7e01175f2b7">PayPal</a>. Developers are choosing Apollo Federation because it’s a proven approach for rapidly scaling a graph across multiple teams.</p>



<p>Today, we’re excited to celebrate the next major milestone: Apollo Federation 2. The new version builds on the success of the original with an improved shared ownership model, enhanced type merging, and cleaner syntax for a smoother developer experience. It’s backwards compatible, requiring no major changes to your subgraphs. <a href="https://www.apollographql.com/docs/federation/v2/quickstart/">Try the alpha today!</a> 🚀</p>

<p>Apollo Federation is an architecture for declaratively composing subgraphs into a unified graph. Each team can own their slice of the graph independently, empowering them to deliver autonomously and incrementally.</p>



<p>Designed in collaboration with the GraphQL community, Federation 2 is a clean-sheet implementation of the core composition and query-planning engine at the heart of Apollo Federation. We’ve improved the developer experience by adding deeper static analysis, cleaner error messages, and new composition hints that help you catch errors sooner and understand how your schema impacts performance. With the new version, we’ve streamlined common tasks like extending a type and simplified advanced workflows like migrating a field across subgraphs with no downtime.</p>



<p>Following in the footsteps of modern infrastructure projects like Elasticsearch and MongoDB, <a href="https://www.apollographql.com/blog/announcement/moving-apollo-federation-2-to-the-elastic-license-v2">we’re moving Federation 2 to the Elastic License v2</a> &#8212; an open and&nbsp;permissive license with few restrictions. This change shouldn’t affect the vast majority of our community, and the new code is still free to use and modify. Subgraph packages will remain MIT, as well as the 0.x Federation packages, so there are no changes to what you’re doing today.</p>

<p>Federation 2 adds first-class support for shared interfaces, enums, and other value types. Common tasks like extending a federated type or denormalizing a field for better performance are now possible without special directives and keywords.</p>

<p>Apollo Federation already supports a shared ownership model that lets you spread a federated type across subgraphs to distribute its implementation. You can reuse common value types like interfaces and enums. However, there are restrictions on how shared types can be defined and evolved. As a result, teams may find themselves stuck when making changes to shared types until all subgraphs are able to deliver a coordinated change in lockstep.</p>



<p>Federation 2 removes these restrictions with an improved shared ownership model and enhanced type merging that enables teams to deliver smaller incremental changes with a cleaner separation of concerns.</p>



<p><strong>Flexible value type merging </strong>is now supported, so value types don’t need to be identical across subgraphs. Value type definitions are now merged into a single unified type, much like type merging support for federated types today. Smaller incremental changes, like adding a field, can often be rolled out one subgraph at a time.</p>



<p><strong>Federated types have improved shared ownership,</strong> which means fields can now exist in multiple subgraphs simultaneously. This paves the way for natively supported field migrations with an asynchronous transfer of ownership from one subgraph to another with no downtime or tight release coordination.</p>

<p>Federation 2 has deeper static analysis, better error messages and a new generalized composition model that helps you catch more errors at build-time instead of at runtime. The rewritten composition engine now validates all theoretically possible queries and provides more descriptive error messages when a query can’t be satisfied.</p>

Announcing Apollo Federation 2


<p>Today, we are introducing <a href="https://www.apollographql.com/blog/announcement/backend/announcing-federation-2">Apollo Federation 2</a>, a major update to our graph composition technology that lets developers build and evolve a unified graph in a modular, principled way. Federation 2 is a new implementation of our query planner and execution gateway that introduces a more flexible model for how types and fields compose across subgraphs. As part of this release, we’re changing the license for the new core federation libraries to the <a href="https://www.apollographql.com/docs/resources/elastic-license-v2-faq">Elastic License v2</a> (ELv2).</p>

<p>The Apollo developer community is at the heart of everything we do. As stewards of our community, we have a responsibility to prevent harm from anyone who intends to exploit our work without contributing back. We want to continue serving you by funding the development of important open-source graph technology, like our MIT-licensed projects Apollo Client, Apollo Server, and <code>apollo-rs</code>, for years to come. To honor that commitment, we’re moving Apollo Federation 2 to the Elastic License v2 (ELv2).</p>



<p><br>Open-source licensing is evolving with the cloud. Many successful companies built on open-source technology (such as <a href="https://www.elastic.co/blog/elastic-license-v2">Elastic</a>, <a href="https://www.mongodb.com/blog/post/mongodb-now-released-under-the-server-side-public-license">MongoDB</a>, and <a href="https://www.confluent.io/blog/license-changes-confluent-platform/">Confluent</a>) have followed the path we’re taking to protect their communities and combine open, collaborative development with the benefits of cloud services that are easy to adopt and manage. In that spirit, we worked with <a href="https://heathermeeker.com/about-me/">Heather Meeker</a>, a lawyer specializing in open-source software who has worked with Mozilla and Elastic, to steer us toward the best open license for Apollo Federation.</p>



<h2 class="wp-block-heading"><a href="#elastic-license-v2" aria-hidden="true" class="aal_anchor" id="elastic-license-v2"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a><strong>Elastic License v2</strong></h2>



<p>Instead of creating our own license, we chose ELv2 because of its simplicity and permissiveness. You shouldn’t have to involve your company’s legal department to adopt Apollo Federation, which is why we chose a license that’s already familiar if you’re using Elasticsearch. Although this change shouldn’t affect the vast majority of our community and customers, we want your migration to Apollo Federation 2 to be friction-free. Read <a href="https://www.apollographql.com/docs/resources/elastic-license-v2-faq">the FAQ</a> for more guidance.</p>



<p>The <a href="https://www.elastic.co/licensing/elastic-license">Elastic License v2 (ELv2)</a> is simple and permissive. You can use, copy, modify, and distribute the software as long as you stay within three limitations. You can’t:</p>



<ol class="wp-block-list"><li>Provide federation tooling as a managed service</li><li>Circumvent the license key functionality or remove/obscure features protected by license keys&nbsp;</li><li>Remove or obscure any licensing, copyright, or other notices</li></ol>



<p>There is no impact to most of our community and customers. Just as before, running a federated graph in production (both public and private) is permitted, as is modifying or extending any part of the federation code. To address your questions, we’ve included some examples in <a href="https://www.apollographql.com/docs/resources/elastic-license-v2-faq">our FAQ</a> that explain the limitation on “managed services.”</p>

<p>Excluding our Federation 2 libraries, nearly all of our 100+ public repositories on <a href="https://github.com/apollographql">GitHub</a> are MIT-licensed. The open-source libraries you know and love, such as Rover, Apollo Client, and Apollo Server, will stay MIT-licensed.</p>



<p>Apollo Federation 0.x libraries will remain MIT-licensed. We want you to migrate at your own pace, so we will actively maintain the Apollo Federation 0.x packages by merging compatibility updates, bug fixes, security patches, and select feature enhancements through the end of 2022.</p>



<p>We’re grateful for the subgraph maintainers who have built a healthy ecosystem around Apollo Federation. Over 12 GraphQL servers, <a href="https://www.apollographql.com/docs/federation/other-servers/">in languages ranging from Kotlin to Ruby</a>, all support Apollo Federation for composing subgraphs. All subgraph libraries under <code>@apollo/subgraph</code> will remain MIT-licensed.</p>



<p>We’re committed to developing and maintaining open-source software for the graph ecosystem. It’s why we’ve released software we use to build Apollo Federation, such as <a href="https://www.apollographql.com/blog/announcement/tooling/apollo-rs-graphql-tools-in-rust/">apollo-rs</a> (a GraphQL parser for Rust), under the MIT license.</p>

<p>When <a href="https://www.elastic.co/blog/elastic-license-v2">the Elastic License v2 was released</a>, Elastic CEO Shay Banon called upon open-source companies facing a similar decision to “coalesce around a smaller number of licenses.” We’re excited to be part of this coalition of modern infrastructure companies building businesses that empower developers. Adopting software shouldn’t require a legal degree to decipher complex licenses and restrictions, which is why we are championing a single, standard open license with the simplest language and least amount of limitations necessary.</p>



<p>Not only do you deserve a friction-free development experience, you also deserve choice. We’re seeing a rapid shift toward unbundling the cloud where you can compose the best tools and services for your needs by mixing and matching them seamlessly. You should pick the stack that’s best for you, instead of picking a service because it comes from the same vendor providing other parts of the stack.</p>



<p>Apollo has always been about helping developers build amazing applications. Moving the Apollo Federation libraries and gateway to ELv2 helps us focus on our mission: empowering all of you.</p>

apollo-rs: spec-compliant GraphQL tools in Rust

Launch with confidence: introducing the Apollo Studio Launches dashboard


<p>Ever faced the conundrum of how to share your GraphQL schema with users outside of your organization, perhaps with partner or vendor developers? If so, Apollo now has a simple solution for you! We recently launched the ability to make graphs in Apollo Studio publicly visible so that you share your graph with anyone, even those without a Studio login.</p>

<p>Making your graph publicly visible is as easy as flipping a switch. Simply navigate to the Settings page for your graph in Apollo Studio and under the Access tab, set <em>a variant of your choosing as “public.” </em>That particular variant of your graph is now publicly visible in Apollo Studio!</p>

<p>You can share the public link with any user, even outside of the Studio organization to explore and consume your graph!</p>



<p><strong>⚠️ Note:</strong> When a specific graph variant is marked as “public”, any unauthenticated user on the internet with the link to the public variant can access its schema. However, accessing endpoint to query data could require authentication depending on the GraphQL endpoint configuration.</p>

<p>You may be wondering, “GraphQL already has introspection, why shouldn’t I just use that?”&nbsp;Well, in addition to the many <a href="https://www.apollographql.com/blog/graphql/security/why-you-should-disable-graphql-introspection-in-production/">security considerations</a> that make disabling introspection in production a good idea, there are also many UX benefits that you miss out on with introspection alone.</p>

<p>By making your graph public in Apollo Studio, every developer automatically gets access to the README, schema docs, changelog, and Explorer, all in one central location. No more building custom documentation portals and changelogs that have to be manually updated.</p>

<p>A key problem with introspection is that it makes your entire graph visible, including things like experimental fields that you may not want external developers to use yet. With Apollo Studio, you can make an approved, production variant public and keep private, pre-production variants to create and test new fields. In the near future, we’ll be adding more features to make sharing even more customizable!</p>

We recently introduced three of the most requested features from our developer community &#8211; tabs in Explorer, offline support for local development in Sandbox, and an improved integration experience between VS Code and Apollo Studio. The request for tabs in Explorer, especially, has been overwhelming:</p>

Offline support for local development in Sandbox</strong></h2>



<p>We launched <a href="https://www.apollographql.com/blog/announcement/platform/apollo-sandbox-an-open-graphql-ide-for-local-development/">Apollo Sandbox</a> three months ago. And now, we are making it available offline for local development. Flaky internet? Worry no more! If you are developing <em>locally</em> using Sandbox, you can continue to work without any internet connection.&nbsp;</p>



<p>⚠️ <strong>Note:</strong> you’ll need to load at least one Sandbox tab while you’re connected to the internet to update to the latest bundle, but after that, you can continue to work without any internet connection.</p>

Run operations in Apollo Studio from VSCode</strong></h2>



<p>The final feature that we recently added is the “Run in Studio” button in our <a href="https://marketplace.visualstudio.com/items?itemName=apollographql.vscode-apollo">VS Code extension</a>. There is now a hover on the play button in VS Code, which opens the exact operation and fragments that you want to test in Apollo Studio Explorer, saving you dozens of clicks and the tedious task of setting up an operation to test!</p>

<p>So what are you waiting for? All these features are now available in Apollo Studio Explorer and Apollo Sandbox. <a href="https://studio.apollographql.com/sandbox/explorer?endpoint=https%3A%2F%2Fapi.spacex.land%2Fgraphql%2F&amp;explorerURLState=N4IgJg9gxgrgtgUwHYBcQC4QEcYIE4CeABADICGMSUAFggM5HAA6SRRANhVbQ862xy40A%2BgQRk8LAUTgBLOnVkQkwpGURSiAXxZaQAGhAA3CbLIAjdvQwgQWoA">Head over there</a> and try them out! And as always, we love hearing from you, so if you have any feedback, please drop a post on the <a href="https://github.com/apollographql/apollo-studio-community/issues">Apollo Studio GitHub Community</a>!</p>


We’re shipping 3 of our most requested features!


<p>When you’re maintaining a graph that’s used by multiple developers, it’s important to make sure everyone is on the same page by providing instructions on how to get started with consuming and contributing to the graph. Today, we’re introducing a way to do that natively in Apollo Studio with the new README page.</p>



<p>The README appears as a new 🏠 icon in the left nav in Apollo Studio and will now be the default page shown when navigating to any graph in Apollo.</p>



<h2 class="wp-block-heading"><a href="#what-is-the-readme" aria-hidden="true" class="aal_anchor" id="what-is-the-readme"><svg aria-hidden="true" class="aal_svg" height="16" version="1.1" viewBox="0 0 16 16" width="16"><path fill-rule="evenodd" d="M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z"></path></svg></a>What is the README?</h2>



<p>The new page includes helpful graph metadata like its name, when it was last updated, its endpoint, the most recent commit hash, links to Explorer and its changelog, and, most importantly, a README! As more developers and teams begin to use your graph, the README ensures that everyone has the information they need to onboard quickly and more independently.</p>

<p>The README for each variant contains default markdown content to help get you started, but it can easily be updated to include any pertinent information for your graph like:</p>



<ul class="wp-block-list"><li>A description of your graph</li><li>Instructions for access and authentication</li><li>Example operations to showcase how the graph can be used</li><li>And more!</li></ul>



<p>Unlike a plain markdown document, the README in Apollo Studio also offers graph shortcodes that allow you to reference graph variables with just a click.</p>

Create a README to onboard developers to the graph


<p>Today, we’re delighted to share that we’ve raised a $130M Series D led by Insight Ventures, with participation from existing investors Andreessen Horowitz and Matrix Partners. This new round is an exciting milestone for Apollo, now valued at over $1.5B.</p>



<p>We see this news as a win for developers everywhere because Apollo’s mission is to help app developers help the world. We will use the funding to create pioneering open-source graph technology that makes app development faster and more accessible for everyone.</p>



<p>The graph has exploded in popularity among developers. 86% of JavaScript developers rank GraphQL as the <a href="https://2020.stateofjs.com/en-US/awards/">top technology they want to learn</a>. Developers trust Apollo to implement their graph, with over 17M monthly open-source downloads and over 6B queries run on the Apollo graph each day.</p>



<p>Apollo has always been first and foremost a developer community, and I’m so proud of what we’ve all accomplished together. It’s an exciting time for all of us and I can’t wait for what’s next. 🚀</p>

<p>We created Apollo to solve the biggest drag on app developer productivity: the data layer that connects apps to backend services.</p>



<p>Today, instead of building features, developers spend the majority of their time writing data-plumbing code to connect an ever-increasing number of clients and microservices. Architectures such as backends-for-frontends and API gateways add to the complexity for client development teams, who have to duplicate data-fetching code for each client they support.</p>



<p>The <strong>graph</strong> is a new layer of the stack that solves this problem by connecting apps to the backend microservices they rely on in a unified way. Client developers write a single GraphQL query to fetch all the data they need, while frontend and backend teams can rely on the graph as a shared contract without tightly coupling their work.</p>



<figure class="wp-block-image alignwide size-large"><img loading="lazy" decoding="async" width="1024" height="319" src="https://wp.apollographql.com/wp-content/uploads/2021/08/apollo-graph-diagram-1-1024x319.png" alt="The graph connects client apps to backend microservices in a unified way." class="wp-image-8691" srcset="https://wp.apollographql.com/wp-content/uploads/2021/08/apollo-graph-diagram-1-1024x319.png 1024w, https://wp.apollographql.com/wp-content/uploads/2021/08/apollo-graph-diagram-1-300x93.png 300w, https://wp.apollographql.com/wp-content/uploads/2021/08/apollo-graph-diagram-1-768x239.png 768w, https://wp.apollographql.com/wp-content/uploads/2021/08/apollo-graph-diagram-1.png 1108w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p>Engineering leaders in every industry are choosing Apollo because the graph has transformed how companies develop apps. Companies in industries ranging from retail (Walmart, Wayfair), financial services (PayPal), and media (The New York Times) have accelerated product delivery with a graph. Expedia was able to rebuild their entire Trips experience in less than a year with an Apollo graph, estimated to take three years with their old architecture.</p>



<p>Developers are driving the momentum behind the graph and changing how companies build software. Their technology choices can have a profound impact on the global economy. That’s why Apollo is dedicated to our mission to help developers help the world.</p>

<p>While the graph’s flexibility and power is a great strength, it can also become a drawback when teams spin up multiple, unconnected graphs without a strategy. It’s important to be intentional when rolling out a graph and adopt a unified graph strategy once GraphQL usage spreads across multiple teams.</p>

<p>A <strong>unified graph</strong> provides a single view of your company’s data, services, and capabilities. The Apollo Graph Platform helps developers incrementally adopt a unified graph with end-to-end tooling built on Apollo’s open-source software.</p>



<p>When developers adopt a unified graph, they can build functionality faster than ever before while maintaining a consistent UX across platforms. That speeds their progress in creating apps that make the world better for all of us.</p>

<p>The exponential growth of the Apollo community over the last two years has been both exhilarating and humbling. We are grateful for your support and the opportunity to serve the community. Many thanks to our customers for choosing to partner with Apollo to power their graphs. And thank you to all the Apollonauts who got us to this point.</p>



<p>This is just the beginning. We have only scratched the surface of what is possible with graph technology, and there is much more in store. I believe that the graph is a foundational technology that will truly change the world, just as the cloud, mobile devices, and big data have impacted how we all use technology every day. As excited as I am about our progress, I’m even more energized by what’s to come.</p>


Apollo raises $130M to pioneer the Graph for app developers


<p>Today, we’re introducing audit logs in Apollo Studio Enterprise. With audit logs, you can export a data file with key actions taken within your organization.</p>



<p>As your graph scales to more teams in your organization, you need visibility into all of the potential change points on your graph that could affect its stability or performance. We built audit logs to give you more confidence in your graph governance and help you meet any compliance or security requirements.</p>



<p><strong>Use Cases for Audit Log</strong></p>



<ul class="wp-block-list">
<li>Investigate an incident and see what actions lead up to that incident by exporting a log for a time period and graph</li>



<li>See what actions an individual has taken within a time period</li>



<li>Investigate your automated systems that are changing the graph</li>
</ul>



<p><strong>Some actions tracked by audit log:</strong></p>



<ul class="wp-block-list">
<li>Creating a graph or variant</li>



<li>Publishing of schema/subschema</li>



<li>Provisioning or inviting users</li>



<li>Adjusting billing</li>



<li>Provisioning or deleting an API key</li>



<li>Adjustments to settings for schema checks</li>
</ul>



<p>This is a partial list of what audit logs track, you can see the more complete list of actions tracked in our <a href="https://www.apollographql.com/docs/studio/audit-log/" target="_blank" rel="noreferrer noopener">docs</a>. Audit logs include actions done by individuals as well as automated actions via the API or CLI. Data for the audit log is retained for up to 180 days<strong>.</strong></p>



<p><p><strong>How to download an audit log</strong></p><p>Audit logs are accessible by organization admins via a new Audit tab inside Apollo Studio UI. When requesting a log, you can filter your exports to a specific actor, action on a specific graph, and/or specific time window. Once an audit log export is requested you’ll receive an on-screen indication as well as an email notification when the log is ready for download.</p></p>

Audit Logs now available in Apollo Studio Enterprise


<p>How do you debug or optimize a request as it travels through all the layers of your stack: from the client, through the Apollo Gateway, through your subgraph services, all the way to your databases?</p>



<p>First, you need visibility into what your code is doing during that request, regardless of how that work is distributed across machines. Fortunately, this is easier than ever with a Cloud-Native Computing Foundation project called <a href="https://opentelemetry.io/">OpenTelemetry</a>!</p>



<p>As of version 0.31.1, <a href="https://www.apollographql.com/docs/federation/api/apollo-gateway">@apollo/gateway</a> natively supports OpenTelemetry as part of a complete picture of the performance and reliability of a federated GraphQL request. You can find <a href="https://www.apollographql.com/docs/federation/opentelemetry/">the documentation here</a>.</p>



<p>In this article, I’ll cover some OpenTelemetry basics, talk about the new support for OpenTelemetry in Apollo Gateway, and explain how Apollo Studio and OpenTelemetry work together to give you a complete picture of your graph.</p>

<p>OpenTelemetry (or OTel) is “an observability framework for cloud-native software”. It is a collection of libraries, systems, and applications for instrumenting, collecting, and exporting information about workloads that span multiple applications.</p>



<p>A unit of work in OTel is a “span”. You can wrap a function call in a span, recording its duration and other metadata. You can also install instrumentation that automatically hooks into modules and functions, like the <a href="https://www.npmjs.com/package/@opentelemetry/instrumentation-http">HTTP instrumentation</a> for Node.js.</p>



<p>A collection of related spans is called a “trace”. In a single system, a trace is very similar to a stack trace. But what makes OpenTelemetry (and its predecessors, OpenTracing and OpenCensus) powerful is the ability to correlate spans across systems. It does this by propagating trace identifiers in remote calls. When making HTTP requests, for example, OTel instrumentation adds trace IDs as HTTP headers.</p>



<p>Once you have a trace, you can aggregate them in a “collector” and efficiently send them to your observability tools with an “exporter”.</p>

<p>There’s obviously a lot more to OpenTelemetry (<a href="https://opentelemetry.io/docs/concepts/what-is-opentelemetry/">see the docs!</a>), but that covers it in the context of Apollo Federation.</p>

<p>Apollo Server has always supported OpenTelemetry via the <a href="https://www.npmjs.com/package/@opentelemetry/instrumentation-graphql">@opentelemetry/instrumentation-graphql</a> library, which instruments the underlying <a href="https://www.npmjs.com/package/graphql">graphql.js</a> library.</p>



<p>However, Apollo Gateway doesn’t use graphql.js to execute a GraphQL request; instead, it executes a “query plan”, coordinating smaller requests to your subgraph services and assembling them into a single response. The Gateway executor has a few phases:</p>



<ul class="wp-block-list"><li>Validation</li><li>Planning</li><li>Execution</li><li>Fetching</li><li>Postprocessing</li></ul>



<p>Apollo Gateway now instruments these phases as spans in an OTel trace. Combined with HTTP instrumentation, which propagates the trace ID as headers in requests to subgraphs, we can now connect the gateway query planning and execution to the actual GraphQL field resolution work in your subgraph services.</p>



<p>Check out our <a href="https://www.apollographql.com/docs/federation/opentelemetry/#1-install-required-libraries">documentation on setting up OpenTelemetry</a> in your Apollo Gateway and Apollo Server apps.</p>



<p>Even if you’re using GraphQL framework other than Apollo Server or a language other than JavaScript, you can still use OTel to instrument your application. There are OTel instrumentation libraries for many other languages and frameworks, and <a href="https://opentelemetry.io/registry/?s=graphql&amp;component=&amp;language=">GraphQL-specific OTel support</a> is small but growing.</p>

<p>Instrumenting a request is cool, but it’s not very useful on its own. You can export traces into many different systems to view, inspect, or search traces.</p>



<p>The open-source projects Zipkin and Prometheus both support OpenTelemetry. Here’s an example of a federated GraphQL request in Zipkin.</p>

<p>OpenTelemetry is great at recording what happened, but it doesn’t tell you much about what <em>could</em> happen. Apollo Studio uses the declarative nature of GraphQL to help you catch potential errors before they happen. Consider this GraphQL operation:</p>



<pre class="wp-block-prismatic-blocks"><code class="language-graphql">query ProductsPage($categoryId: ID!) {
  products(category: $categoryId) {
    nodes {
      sku
      price
      reviews { # could return null
        nodes {
          id
          body
          rating
          author {
            name
            photoUrl 
          }
        }
      }
    }
  }
}</code></pre>



<p>If the <code>Product.reviews</code> field returns null, then the GraphQL executor won’t run resolvers for any of the fields nested inside that selection like <code>Review.id</code>, <code>Review.body</code>, or <code>Author.name</code>. OTel instrumentation won’t record any spans, so you’ll have no data about those fields.</p>



<p>However, if you remove or change the <code>Author.name</code> field, you could break all the clients that include that field in their operations.</p>



<p>We designed <a href="https://www.apollographql.com/docs/federation/metrics/">Apollo Federated Tracing</a> to collect field usage regardless of what actually happens (or doesn’t happen!) in your services. Our tracing data powers the <a href="https://www.apollographql.com/docs/studio/schema-checks/">Schema Checks</a> feature, alerting you of potentially breaking changes and giving you confidence as you evolve your API.</p>

Introducing Open Telemetry for Apollo Federation


<h1 class="wp-block-heading"></h1>



<p>Two weeks ago, we hosted a<a href="https://www.apollographql.com/events/tech-talk/from-schema-stitching-to-federation-expedias-journey/"> webinar with Shane Myrick</a>, Senior Software Developer at Expedia Group entitled, “From Schema Stitching to Federation: Expedia’s Journey.” Shane’s talk covered Expedia’s motivation for adopting GraphQL and why they needed a distributed approach for managing their graph.&nbsp;</p>



<p>Prior to adopting GraphQL, the Expedia Group faced the challenge of delivering a wide array of travel experiences across a growing number of platforms and clients. Expedia adopted GraphQL as a way to simplify the connection layer between their backend capabilities and front-end clients. The graph provides a single point for clients to connect to and for service teams to expose to clients. Adopting the graph helped Expedia reduce the friction and the number of connections and coordination points across their boundary layers. They also saw benefits from adopting a strongly typed language and the performance benefits of adopting a declarative language that allows clients to request just the data they need. Lastly, they saw benefits in being able to extend and merge common types.</p>

<p><em>Building a graph across Expedia’s suite of travel products</em></p>



<p><strong>Scaling their graph with schema stitching</strong></p>



<p>As Expedia began to add more capabilities to their graph, they were concerned about it becoming a single point of failure and preventing conflicts as the number of contributors to their graph increased.</p>



<p>A core requirement was that they wanted to have one schema and one endpoint for their clients while allowing individual teams to own their services and update those services on their cadence. Expedia started using a gateway as a layer between their GraphQL services and their clients to achieve this. They started off using schema stitching as a way to merge types.</p>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="534" src="https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase6482536c5e195d99f-1024x534.png" alt="" class="wp-image-22929" srcset="https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase6482536c5e195d99f-1024x534.png 1024w, https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase6482536c5e195d99f-300x157.png 300w, https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase6482536c5e195d99f-768x401.png 768w, https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase6482536c5e195d99f-1200x626.png 1200w, https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase6482536c5e195d99f.png 1276w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p><em>Using a gateway to provide a single endpoint for developers across services</em></p>



<p>However, one downside of schema stitching is that Expedia needed to write a significant amount of gateway code to link types across different services. Shane walked through an example of how Expedia wrote code in their gateway to extend a type from their property service to include another type from their reviews service so that clients could query reviews by property. This code enabled the gateway to understand what types existed in different services and merged and extended the schema.</p>



<figure class="wp-block-image size-full"><img loading="lazy" decoding="async" width="894" height="728" src="https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase64d41caef3915787fa.png" alt="" class="wp-image-22931" srcset="https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase64d41caef3915787fa.png 894w, https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase64d41caef3915787fa-300x244.png 300w, https://wp.apollographql.com/wp-content/uploads/2023/11/pngbase64d41caef3915787fa-768x625.png 768w" sizes="auto, (max-width: 894px) 100vw, 894px" /></figure>



<p><em>Writing custom stitching code in the gateway.</em></p>



<p><strong>Challenges emerge with schema stitching</strong></p>



<p>As they introduced more stitching code in their gateway, challenges emerged. Their gateway code was becoming more complex, and there was no way to determine the “true schema” without running the gateway. Schema changes required a change to the underlying service and changes to the gateway code and a redeploy of all gateways. This complexity started to cause issues with managing their infrastructure. Additionally, Expedia began to be concerned about preventing conflicts when managing updates to their gateway code.</p>



<p><strong>Moving to Apollo Federation for their graph architecture</strong></p>



<p>When Apollo Federation was <a href="https://www.apollographql.com/blog/announcement/apollo-federation-f260cf525d21/">announced</a> in 2019, Expedia began investigating it as an alternative to schema stitching. They liked that<a href="https://www.apollographql.com/docs/federation/"> Federation</a> was published as an open-source <a href="https://www.apollographql.com/docs/federation/federation-spec/">specification</a> and its declarative, directive-based approach to merging types. Federation’s support for all GraphQL servers was compelling as Expedia had invested a lot in Kotlin and even open-sourced their own<a href="https://github.com/ExpediaGroup/graphql-kotlin"> GraphQL Kotlin</a> server.</p>



<p>With Federation, Expedia could use GraphQL directives to extend services without writing any custom gateway code. They did have to write resolver code in the underlying service to extend the type, but this was easier than the stitching approach as each team could own the evolution of its service.</p>



<p>Expedia saw the following benefits from adopting federation:</p>



<ol class="wp-block-list">
<li>Standardized the implementation as developers could follow the declarative approach to writing schemas.&nbsp;</li>



<li>Able to do offline composition and validation of the schema without spinning up a gateway.&nbsp;</li>



<li>Changed the coordination across teams to review gateway code to have a more strategic conversation about the schema architecture and design. The federated approach made reviewing changes to the schema easier as people reviewed the schema files vs. reviewing many lines of code.</li>
</ol>



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="559" src="https://wp.apollographql.com/wp-content/uploads/2021/07/image-11-1024x559.png" alt="image.png" class="wp-image-8113" srcset="https://wp.apollographql.com/wp-content/uploads/2021/07/image-11-1024x559.png 1024w, https://wp.apollographql.com/wp-content/uploads/2021/07/image-11-300x164.png 300w, https://wp.apollographql.com/wp-content/uploads/2021/07/image-11-768x420.png 768w, https://wp.apollographql.com/wp-content/uploads/2021/07/image-11-1200x655.png 1200w, https://wp.apollographql.com/wp-content/uploads/2021/07/image-11.png 1276w" sizes="auto, (max-width: 1024px) 100vw, 1024px" /></figure>



<p> <em>Example of service level resolver code to extend a type across services</em></p>



<p><strong>Making the switch</strong></p>



<p>To safely migrate from stitching to Federation, Expedia first worked with the individual service teams to add the necessary federated directives, schemas, and resolver code to their GraphQL servers. Then Expedia set up two separate Apollo servers: one using schema stitching and one set up for Apollo Federation. They set up two variants in Apollo Studio’s schema registry to reflect the two different setups. They used a traffic router in front of the gateways to route traffic between the two graphs, eventually ramping up to a 50/50 split between the stitching and federated gateways.</p>



<p><strong>Benefits from moving from schema stitching to federation</strong></p>



<p>By running schema stitching versus Apollo Federation as an A/B test, Expedia was able to quantify the impact of moving to Federation, and they were pleased to see some immediate benefits. First, the federated implementation improved gateway processing latency which improved application performance compared to schema stitching. As Shane explained, “With Federation, we saw a reduced latency compared to schema stitching. Because there was a reduced latency, we were able to reduce our compute quite significantly by about 50%” Lastly, Expedia was able to delete many lines of gateway code which simplified their gateway deployments. Now, they can use almost a stock version of the gateway, making it easy for them to scale the gateway across their many brands since they no longer have much custom code in the gateway.</p>



<p><strong>Key takeaways from moving to Federation</strong></p>



<p>After moving to Federation, Shane says Expedia solved key customer and client problems by providing a single endpoint while ensuring that the service teams could independently deploy their changes. They also were able to reduce the potential impact of the gateway going down. They could remove the friction of having to work with multiple code bases to modify the schema. Additionally, they found the declarative approach of the Federation was more straightforward, which made it easier for teams to understand what’s happening and see the overall architecture, which elevated the discussions around the graph and reduced the coordination and complexity of scaling the graph.</p>
