Create GraphQL Schema

// The GraphQL schema in string form
const typeDefs = `
  type Query { books: [Book] }
  type Book { title: String, author: String }
`;
export default typeDefs;

Create GraphQL Resolvers

// Some fake data
const books = [
  {
    title: "Harry Potter and the Sorcerer's stone",
    author: 'J.K. Rowling',
  },
  {
    title: 'Jurassic Park',
    author: 'Michael Crichton',
  },
];

// The resolvers
const resolvers = {
  Query: { 
    books: (parent, args, context, info) => books
  },
};
export default resolvers;

Create Server

$ nano index.js
import express from 'express';
import bodyParser from 'body-parser';
import { graphqlExpress, graphiqlExpress } from 'apollo-server-express';
import { makeExecutableSchema } from 'graphql-tools';

import typeDefs from './schema';
import resolvers from './resolvers';

// Put together a schema
const schema = makeExecutableSchema({
  typeDefs,
  resolvers,
});
// Initialize the app
const app = express();

// The GraphQL endpoint
app.use('/graphql', bodyParser.json(), graphqlExpress({ schema }));

// GraphiQL, a visual editor for queries
app.use('/graphiql', graphiqlExpress({ endpointURL: '/graphql' }));

// Start the server
app.listen(3000, () => {
    console.log('Go to http://localhost:3000/graphiql to run queries!');
});

Run server
