Sample server from apollo-server documentation
const { ApolloServer, gql } = require('apollo-server');
// This is a (sample) collection of books we'll be able to query
// the GraphQL server for. A more complete example might fetch
// from an existing data source like a REST API or database.
const books = [
title: 'Harry Potter and the Chamber of Secrets',
author: 'J.K. Rowling',
title: 'Jurassic Park',
author: 'Michael Crichton',
// Type definitions define the "shape" of your data and specify
// which ways the data can be fetched from the GraphQL server.
const typeDefs = gql`
# Comments in GraphQL are defined with the hash (#) symbol.
# This "Book" type can be used in other type declarations.
type Book {
title: String
author: String
# The "Query" type is the root of all GraphQL queries.
# (A "Mutation" type will be covered later on.)
type Query {
books: [Book]
// Resolvers define the technique for fetching the types in the
// schema. We'll retrieve books from the "books" array above.
const resolvers = {
Query: {
books: () => books,
// In the most basic sense, the ApolloServer can be started
// by passing type definitions (typeDefs) and the resolvers
// responsible for fetching the data for those types.
const server = new ApolloServer({ typeDefs, resolvers });
// This `listen` method launches a web-server. Existing apps
// can utilize middleware options, which we'll discuss later.
server.listen().then(({ url }) => {
console.log(`🚀 Server ready at ${url}`);
