Easily translate your backends to a GraphQL schema.
const { makeExecutableSchema } = require('graphql-tools');
const typeDefs = `
type Query { books: [Book] }
type Book { title: String, author: String }
`;
const resolvers = {
Query: {
books: () => fetch('https://api.example.com/books')
},
};
const schema = makeExecutableSchema({ typeDefs, resolvers });Build and run a GraphQL schema with just a few lines of code.
A GraphQL server is a thin translation layer over your existing backends. It's easy to write one:
- Describe your data with a schema
- Write resolvers that fetch the fields in your schema from your existing backend
- Pass through authentication information from the request to the backends
You can use JavaScript, as in the example here, or any language you're already familiar with.
Productive GraphQL API development.
Schema-first approach
Develop your schema with concise, declarative syntax, and fill in the logic with resolver functions.
One-step mocking
Mock your GraphQL schema with one line of code, so you can develop your UI in parallel with the API.
Powerful schema directives
Factor chunks of schema functionality into directives you can easily reuse around your schema.
Schema stitching
Combine and remix multiple GraphQL schemas into one, as if you're using Lego blocks.
GraphQL subscriptions
Add event-based data streaming to your GraphQL API, enabling realtime features in your app.
Tracing and cache control
Apollo Server has everything you need to get performance insights and caching with Engine built in.
