This is the Micro integration for the Apollo community GraphQL Server. Read the docs. Read the CHANGELOG.

Basic GraphQL Microservice

This example demonstrates how to setup a simple microservice, using Micro, that handles incoming GraphQL requests via the default /graphql endpoint.

  1. Package installation.
npm install micro apollo-server-micro graphql
  1. index.js
const { ApolloServer, gql } = require('apollo-server-micro');
 
const typeDefs = gql`
  type Query {
    sayHello: String
  }
`;
 
const resolvers = {
  Query: {
    sayHello(parent, args, context) {
      return 'Hello World!';
    },
  },
};
 
const apolloServer = new ApolloServer({ typeDefs, resolvers });
module.exports = apolloServer.createHandler();
  1. package.json
{
  "main": "index.js",
  "scripts": {
    "start": "micro"
  }
}
  1. After an npm start, access http://localhost:3000/graphql in your browser to run queries using graphql-playground, or send GraphQL requests directly to the same URL.

CORS Example

This example demonstrates how to setup a simple Micro + CORS + GraphQL microservice, using micro-cors:

  1. Package installation.
npm install micro micro-cors apollo-server-micro graphql
  1. index.js
const cors = require('micro-cors')(); // highlight-line
const { ApolloServer, gql } = require('apollo-server-micro');
 
const typeDefs = gql`
  type Query {
    sayHello: String
  }
`;
 
const resolvers = {
  Query: {
    sayHello(parent, args, context) {
      return 'Hello World!';
    },
  },
};
 
const apolloServer = new ApolloServer({ typeDefs, resolvers });
module.exports = cors(apolloServer.createHandler()); // highlight-line
  1. package.json
{
  "main": "index.js",
  "scripts": {
    "start": "micro"
  }
}
  1. After an npm start, access http://localhost:3000/graphql in your browser to run queries using graphql-playground, or send GraphQL requests directly to the same URL.

Custom GraphQL Path Example

This example shows how to setup a simple Micro + GraphQL microservice, that uses a custom GraphQL endpoint path:

  1. Package installation.
npm install micro apollo-server-micro graphql
  1. index.js
const { ApolloServer, gql } = require('apollo-server-micro');
 
const typeDefs = gql`
  type Query {
    sayHello: String
  }
`;
 
const resolvers = {
  Query: {
    sayHello(parent, args, context) {
      return 'Hello World!';
    },
  },
};
 
const apolloServer = new ApolloServer({ typeDefs, resolvers });
module.exports = apolloServer.createHandler({ path: '/data' }); // highlight-line
  1. package.json
{
  "main": "index.js",
  "scripts": {
    "start": "micro"
  }
}
  1. After an npm start, access http://localhost:3000/data in your browser to run queries using graphql-playground, or send GraphQL requests directly to the same URL.

Fully Custom Routing Example

This example demonstrates how to setup a simple Micro + GraphQL microservice, that uses micro-router for fully custom routing:

  1. Package installation.
npm install micro microrouter apollo-server-micro graphql
  1. index.js
const { router, get, post, options } = require('microrouter');
const { ApolloServer, gql } = require('apollo-server-micro');
 
const typeDefs = gql`
  type Query {
    sayHello: String
  }
`;
 
const resolvers = {
  Query: {
    sayHello(parent, args, context) {
      return 'Hello World!';
    },
  },
};
 
const apolloServer = new ApolloServer({ typeDefs, resolvers });
const graphqlPath = '/data';
const graphqlHandler = apolloServer.createHandler({ path: graphqlPath });
module.exports = router(
  get('/', (req, res) => 'Welcome!'),
  post(graphqlPath, graphqlHandler),
  get(graphqlPath, graphqlHandler),
);
  1. package.json
{
  "main": "index.js",
  "scripts": {
    "start": "micro"
  }
}
  1. After an npm start, access http://localhost:3000/data in your browser to run queries using graphql-playground, or send GraphQL requests directly to the same URL.
