GraphQL Playground	Visually exploring an Apollo Server

GraphQL Playground is a graphical, interactive, in-browser GraphQL IDE, created by Prisma and based on GraphiQL.

In development, Apollo Server enables GraphQL Playground on the same URL as the GraphQL server itself (e.g. http://localhost:4000/graphql) and automatically serves the GUI to web browsers. When NODE_ENV is set to production, GraphQL Playground (as well as introspection) is disabled as a production best-practice.


Configuring Playground

The Apollo Server constructor contains the ability to configure GraphQL Playground with the playground configuration option. The options can be found on GraphQL Playground's documentation

new ApolloServer({
typeDefs,
resolvers,
playground: {
  settings: {
    'editor.theme': 'light',
  },
  tabs: [
    {
      endpoint,
      query: defaultQuery,
    },
  ],
},
});

Enabling GraphQL Playground in production

To enable GraphQL Playground in production, introspection and the playground can be enabled explicitly in the following manner.

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

const server = new ApolloServer({
  typeDefs,
  resolvers,
  introspection: true,
  playground: true,
});


server.listen().then(({ url }) => {
  console.log(`🚀 Server ready at ${url}`);
});
