Launch Apollo Studio

Deploying with Azure Functions

Deploying your GraphQL server to Azure Functions

This is the Azure Functions integration for the Apollo community GraphQL Server. Read Docs

All examples below was created using Linux environments, if you are working with Windows-based platforms some commands couldn’t work fine.

Note that apollo-server-azure-functions does not provide a mechanism for adding arbitrary middleware to your web server (other that by manually wrapping the handler returned by createHandler in your own handler).


The following must be done before following this guide:

Setting up the project

We will need to create our local project, installing the node.js dependencies and testing locally to make sure that all process will happen fine.

func init apollo-example --worker-runtime node
cd apollo-example
func new --template "Http Trigger" --name graphql

Now, our project is prepared to start! Run func host start command to see the output below.

Core Tools Version:       3.0.3477 Commit hash: 5fbb9a76fc00e4168f2cc90d6ff0afe5373afc6d  (64-bit)
Function Runtime Version: 3.0.15584.0

[2021-06-30T19:22:21.077Z] Worker process started and initialized.


	graphql: [GET,POST] http://localhost:7071/api/graphql

For detailed output, run func with --verbose flag.

Go to http://localhost:7071/api/graphql?name=Apollo and verify if the text with the content: Hello Apollo is appearing at your browser.

(If you see an error about "Incompatible Node.js version", you may need to ensure that the version of node on your PATH is a version supported by Azure Functions by using a tool like nvm. For example, as of June 2021, Azure Functions does not yet support Node 16.)

If you would like to remove the api from the url structure, set the prefix in your host.json file like below:

  "version": "2.0",
  "extensions": {
    "http": {
        "routePrefix": ""

This will make your url look like http://{my-url}/graphql like we would expect for most GraphQL projects.

Sample Code

We will now install the dependencies and test our azure function app using apollo server and graphql. Run the following commands to perform the node.js initialization project and to install the node.js dependencies.

cd apollo-example
npm install apollo-server-azure-functions graphql

Replace the context of the file graphql/index.js with the following:

const { ApolloServer, gql } = require('apollo-server-azure-functions');

// Construct a schema, using GraphQL schema language
const typeDefs = gql`
  type Query {
    hello: String

// Provide resolver functions for your schema fields
const resolvers = {
  Query: {
    hello: () => 'Hello world!',

const server = new ApolloServer({ typeDefs, resolvers });
exports.graphqlHandler = server.createHandler();

Make two changes to graphql/function.json: make the output name $return, and add options to the list of supported methods so that CORS works. Your file should look like:

  "bindings": [
      "authLevel": "function",
      "type": "httpTrigger",
      "direction": "in",
      "name": "req",
      "route": "{*segments}",
      "methods": [
      "type": "http",
      "direction": "out",
      "name": "$return"

The route line is required for the health checks feature and is not otherwise required.

Finally, we need to return to the base folder and run the func host start command again after that, go back to your browser and refresh your page to see the Apollo Server running. You can then run operations against your graph with Apollo Sandbox.

func host start

Deploying the project to Azure using the Azure CLI

Setting up resources in Azure for deployment

Before deploying, a new application must be set up. To do this, we need to create some azure requirements. First, you will need a resource group. To create one run the code below on your terminal, where the --name is the name for the group and --location the region.

az group create --name apollo-examples --location eastus

After creating a resource group, we need to create a storage account to store our code on Azure. You will need to choose a unique name.

az storage account create \
    --name apolloexampleYOURNAME \
    --location eastus \
    --resource-group apollo-examples \
    --sku Standard_LRS

We will publish our application to Azure now using the CLI as well. We need to create a functionapp running the following command.

Note: The function name must be unique.

az functionapp create \
    --resource-group apollo-examples \
    --name apollo-example-YOURNAME \
    --consumption-plan-location eastus \
    --runtime node \
    --functions-version 3 \
    --storage-account apolloexampleYOURNAME

Publishing our project to the function app

After creating a functionapp, it is just to publish our function to azure. The command below could be used to perform releases to all of your functions.

func azure functionapp publish apollo-example-YOURNAME
Getting site publishing info...

Functions in apollo-example:
    graphql - [httpTrigger]
        Invoke url:

Finally, going to the Invoke URL shown at the output above, we will see our result.

Cleaning Up

After completing this tutorial, you can delete all the resources you created during this example from your Azure account by removing the Azure Resource Group called apollo-examples with the az group command:

az group delete --name apollo-examples --yes

Deploying to Azure from VS Code

It is also possible to publish your project from VS Code using the Azure Functions Extension, we recommend referring to Microsoft's documentation on publishing to Azure from VS Code.
