A GraphQL-Based Schema Architecture for Microservices

Nav has just open-sourced a new low-code project that is using GraphQL as-a-syntax to define message and event payload formats. The extensible framework currently generates json-schemas, protobufs and client libraries in golang, python and ruby for payload validation.

That problem has not really been solved yet with OpenAPI and other approaches. What is novel here is the elegance and simplicity of the GraphQL syntax used in the context of schema definitions.
