Apollo Gateway

This package provides utilities for combining multiple GraphQL microservices into a single GraphQL endpoint.

Each microservice should implement the federation schema specification. This can be done either through Apollo Federation or a variety of other open source products.

For complete documentation, see the Apollo Gateway API reference.

Usage

``js
import { ApolloServer } from "@apollo/server";
import { startStandaloneServer } from '@apollo/server/standalone';
import { ApolloGateway, IntrospectAndCompose } from "@apollo/gateway";

const gateway = new ApolloGateway({
supergraphSdl: new IntrospectAndCompose({
subgraphs: [
{ name: "accounts", url: "http://localhost:4001/graphql" }
// List of federation-capable GraphQL endpoints...
],
}),
});

const server = new ApolloServer({ gateway });

// Note the top-level await!
const { url } = await startStandaloneServer(server);
console.log(🚀 Server ready at ${url});
