[Read the CHANGELOG.](https://github.com/apollographql/apollo-server/blob/master/CHANGELOG.md) ```sh npm install apollo-server@beta apollo-server-express@beta ``` ## Express ```js const express = require('express'); const { registerServer } = require('apollo-server-express'); const { ApolloServer, gql } = require('apollo-server'); // 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(); registerServer({ server, app }); server.listen().then(({ url }) => { console.log(`🚀 Server ready at ${url}`); }); ``` ## Connect ```js import connect from 'connect'; const { registerServer } = require('apollo-server-express'); const { ApolloServer, gql } = require('apollo-server'); // 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(); registerServer({ server, app }); server.listen().then(({ url }) => { console.log(`🚀 Server ready at ${url}`); }); ``` ## 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](https://github.com/apollographql/apollo-server/blob/master/CONTRIBUTING.md), take a look at the [roadmap](https://github.com/apollographql/apollo-server/blob/master/ROADMAP.md) and make your first PR!
