Mock any GraphQL schema. All you need is a schema.json or the URL of a GraphQL server that has introspection enabled.

Steps:

• Update the schema to the one you want by either:
  • Replacing schema.json, or
  • Replacing https://api.spacex.land/graphql in package.json and running npm run update-schema
• Running npm start
• Opening localhost:4000 and querying with Playground
