@apollo/gateway

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

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}`);

graphql-tools

graphql-tools is a package that provides a set of utilities to build and manipulate GraphQL schemas in JavaScript. It allows you to create a unified schema from multiple GraphQL services, similar to Apollo Gateway. However, it does not provide the same level of built-in support for federated services and managed federation as Apollo Gateway.

graphql-mesh

graphql-mesh is a package that allows you to create a unified GraphQL schema from multiple sources, including REST APIs, gRPC services, and other GraphQL APIs. It provides a flexible and extensible way to integrate different data sources into a single GraphQL API. Compared to Apollo Gateway, graphql-mesh offers more versatility in terms of the types of data sources it can integrate, but it may require more configuration and setup.
