Customizing Apollo Server 2.0 GraphQL Playground path

index.js

const express = require('express');
const { ApolloServer, gql } = require('apollo-server-express');
const { typeDefs, resolvers } = require('./schema');

// https://www.apollographql.com/docs/apollo-server/features/graphql-playground.html#Enabling-GraphQL-Playground-in-production
const server = new ApolloServer({
  typeDefs,
  resolvers,
  introspection: true,
  playground: {
    settings: {
      'editor.theme': 'light'
    }
  }
});

// Additional middleware can be mounted at this point to run before Apollo
const app = express();
server.applyMiddleware({ app, path: '/somepath' });

// Start the server
const port = 8080;
app.listen({ port }, () => {
  console.log(`Liftoff of Apollo Server at http://localhost:${port}${server.graphqlPath}`)
});
