graphql-s2s

GraphQL S2S (Schema-to-Schema) is a transpiler that extends standard GraphQL SDL with type inheritance, generic types, metadata decoration, and query deconstruction/transformation/rebuilding. Version 0.22.0 is the latest stable release. It allows developers to define reusable schema patterns before transpiling to standard GraphQL syntax for graphql-js and Apollo Server. Key differentiators: supports multiple inheritance, generic type parameters (like Paged<T>), schema-level metadata annotations, and programmatic query manipulation. Unlike graphql-modules or type-graphql, graphql-s2s works purely at the SDL string level without requiring class definitions or decorators.
