Introduction

Apollo Server is an open-source, spec-compliant GraphQL server that's compatible with any GraphQL client, including Apollo Client. It's the best way to build a production-ready, self-documenting GraphQL API that can use data from any source.

You can use Apollo Server as:

• a stand-alone GraphQL server, including in a serverless environment
• an add-on to your application's existing Node.js middleware (such as Express or Fastify)
• a gateway for a federated data graph

Installation

npm install apollo-server-express

First steps

import express from 'express';
import { ApolloServer, gql } from 'apollo-server-express';
 
const app = express();
 
const schema = gql`
  type Query {
    me: User
  }
 
  type User {
    username: String!
  }
`;
 
const resolvers = {
  Query: {
    me: () => {
      return {
        username: 'Robin Wieruch',
      };
    },
  },
};
