graphql-crystal

Instantiate GraphQL schemas directly from SDL strings, providing a clear and visual way to define the API structure as shown in the example schema definition in the README.

Make existing Crystal classes GraphQL-ready by including GraphQL::ObjectType and using the field macro, minimizing code changes for domain models like User and Post in the example.

Register custom structs to automatically parse JSON query variables into typed Crystal objects, reducing boilerplate and enhancing type safety, as demonstrated with PostInput structs.

Support for custom context objects allows passing authentication, logging, or other request-specific data to resolvers, enabling advanced use cases without cluttering resolver logic.
