apollo

fastify-apollo-step

As Apollo offical page said that Apollo Server can work with many Node.js HTTP frameworks, but no fastify in that list. So let's make one.

fastify-apollo-step is designed as a plugin of fastify, just call register to use it.

fastify-apollo-step also supports graphiql/playground module of Apollo Server.

Usage

npm install --save fastify-apollo-step apollo-server-core graphql fastify graphql-playground-html graphql-tools graphql-subscriptions

• by fastify, just need apollo-server-core, not apollo-server

Options

fastify-apollo-step can be configurated with the follow option object, inclues itself configurations and Apollo Server configurations.

const options = {
    path: '/ql',
    context: undefined,
    gqlSchema: undefined,
    typeDefs: typeDefs,
    resolvers: resolvers,
    subscriptions: {
      enabled: true,
      path: '/subscriptions',
      onConnect: (connectionParams, webSocket) => {
      },
      onDisconnect: (webSocket, connectionContext) => {
      }
    },
    graphiql: {
      enabled: true,
      path: '/iql'
    },
    routeBeforeHandler: function (request, reply, done) {
      done();
    }
};

• path: GraphQL module endpoint;
• gqlSchema: GraphQL schema, optional if typeDefs and resolvers exist;
• typeDefs: GraphQL type definitions, optional if schema exists;
• resolvers: GraphQL resolver definitions, optional if schema exists;
• subscriptions: Options of subscription;
• graphiql: Options of GraphiQL of Playground;
• routeBeforeHandler: beforeHandler function of Fastify while calls QL or iQL;

Example

const options = {
  path: '/ql',
  typeDefs: typeDefs,
  resolvers: resolvers,
  ...
};

fastify.register(ApolloFastify, options);

fastify.listen(3000, (err) => {
  if (err) {
      console.error('server starts failed - ', err);
      return;
  }    
  console.log('🚀 Server ready at http://localhost:3000');
});

TypeScript

Do NOT support TypeScript because NOT compatible with latest Fastify.

Ready. But I am not good at TypeScript yet.

To conflict with Fastify Plugin Option, I have to change 'schema' and 'beforeHandler' of FastifyApollo's, Please refer to ./test/ts/subscription.ts.

Test

    npm run query
    npm run mutation
    npm run subscription

Notes: Graphsql query must be with 'operationName' now.

query [querybook] {
  books {
    author
    title
  }
}
