Propel & GraphQXL: the missing language extension

The GraphQL SDL specification lacks tools for reusing code, leading to problems such as copying-pasting common fields across resources, handling CRUD inputs, cursor pagination, and documentation maintenance. GraphQXL is a language built on top of the GraphQL SDL syntax that solves these reusability problems by introducing features like field inheritance, generics, and import statements, allowing developers to write more maintainable and scalable GraphQL schemas.
