What are graphql-playground-middleware-express's main functionalities?

Setting up GraphQL Playground

This feature allows you to set up GraphQL Playground at a specific endpoint in your Express application. In this example, the playground is accessible at '/playground' and it points to the GraphQL endpoint '/graphql'.

const express = require('express');
const { express: playground } = require('graphql-playground-middleware-express');

const app = express();

app.get('/playground', playground({ endpoint: '/graphql' }));

app.listen(3000, () => {
  console.log('Server is running on http://localhost:3000');
});

Customizing GraphQL Playground

This feature allows you to customize the settings of GraphQL Playground. In this example, the editor theme is set to 'dark' and the cursor shape is set to 'line'.

const express = require('express');
const { express: playground } = require('graphql-playground-middleware-express');

const app = express();

app.get('/playground', playground({
  endpoint: '/graphql',
  settings: {
    'editor.theme': 'dark',
    'editor.cursorShape': 'line'
  }
}));

app.listen(3000, () => {
  console.log('Server is running on http://localhost:3000');
});
