Package - apollo-server-express

This is the Express integration of Apollo Server. Apollo Server is a community-maintained open-source GraphQL server that works with many Node.js HTTP server frameworks. Read the docs. Read the CHANGELOG.

npm install apollo-server-express@3.x graphql

Express

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

async function startApolloServer() {
  // 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 });
  await server.start();

  const app = express();
  server.applyMiddleware({ app });

  await new Promise(resolve => app.listen({ port: 4000 }, resolve));
  console.log(`🚀 Server ready at http://localhost:4000${server.graphqlPath}`);
  return { server, app };
}

Connect

Before Apollo Server 3, we officially supported using this package with connect as well. connect is an older framework that express evolved from. For now, we believe that this package is still compatible with connect and we even run tests against connect, but we may choose to break this compatibility at some point without a major version bump. If you rely on the ability to use Apollo Server with connect, you may wish to make your own integration.

Principles

GraphQL Server is built with the following principles in mind:

By the community, for the community: GraphQL Server's development is driven by the needs of developers
Simplicity: by keeping things simple, GraphQL Server is easier to use, easier to contribute to, and more secure
Performance: GraphQL Server is well-tested and production-ready - no modifications needed

Anyone is welcome to contribute to GraphQL Server, just read CONTRIBUTING.md, take a look at the roadmap and make your first PR!
