Express / Connect	Setting up Apollo Server with Express.js or Connect

This is the Express and Connect integration of GraphQL 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

Express

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

// 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 });

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

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

Connect

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

// 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 });

const app = connect();
const path = '/graphql';

app.use(query());
server.applyMiddleware({ app, path });

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

Note; qs-middleware is only required if running outside of Meteor

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!
