Data schema

  • 1
  • 2
  • 3
  • 4
  • 5

Most GraphQL applications can automatically retrieve the schema via Introspection and offer the following features:

  • Autocomplete for fields and arguments
  • Inline documentation of all available queries and fields
  • Query validation before sending requests

Tools such as Postman, Bruno, Insomnia and many GraphQL IDEs support this by default and display the schema documentation directly within their tools.
