What is a .graphql file?
application/graphql
GraphQL files contain schema definitions or operations written in the GraphQL Schema Definition Language, describing types, fields, queries, and mutations. The schema defines a strongly typed API contract that clients query for exactly the data they need. It is a common alternative to REST for API design.
How to use a .graphql file
Use an example GraphQL file to test schema parsers, SDL validation, code generators, and tooling that builds clients or documentation from a type definition.
