Hapi	Setting up Apollo Server with Hapi

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

npm install apollo-server-hapi@beta

Usage

After constructing Apollo server, a hapi server can be enabled with a call to registerServer. Ensure that autoListen is set to false in the Hapi.server constructor.

The code below requires Hapi 17 or higher.

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

const HOST = 'localhost';

const typeDefs = gql`
  type Query {
    hello: String
  }
`;

const resolvers = {
  Query: {
    hello: () => 'hello',
  },
}

async function StartServer() {
  const server = new ApolloServer({ typeDefs, resolvers });

  await registerServer({
    server,
    //Hapi Server constructor options
    options: {
      host: HOST,
    },
  });

  server.listen().then(({ url }) => {
    console.log(`🚀  Server ready at ${url}`);
  });
}

StartServer().catch(error => console.log(error));

For more advanced use cases or migrating from 1.x, a Hapi server can be constructed and passed into registerServer.

const { ApolloServer, gql, registerServer } = require('apollo-server-hapi');
const Hapi = require('hapi');

async function StartServer() {
  const server = new ApolloServer({ typeDefs, resolvers });

  const app = new Hapi.server({
    //autoListen must be set to false, since Apollo Server will setup the listener
    autoListen: false,
    host: HOST,
  });

  await registerServer({
    server,
    app,
  });

  server.listen().then(({ url }) => {
    console.log(`🚀  Server ready at ${url}`);
  });
}

StartServer().catch(error => console.log(error));

Context

The context is created for each request. The following code snippet shows the creation of a context. The arguments are the request, the request, and h, the response toolkit.

new ApolloServer({
  typeDefs,
  resolvers,
  context: async ({ request, h }) => {
    return { ... };
  },
})

Principles

Apollo Server is built with the following principles in mind:

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