    GraphQL Scalars

    GraphQL Scalars

    A library of custom GraphQL Scalars for creating precise schemas

    ...However, for all of GraphQL's greatness, it is missing a couple of things that we have (and you might) find very useful in defining your schemas. Namely GraphQL has a limited set of scalar types, and we have found there are some additional scalar types that are useful in being more precise in our schemas. Thankfully, those sharp GraphQL folks provided a simple way to add new custom scalar types if needed. That's what this package does. GraphQL Scalars is a library of custom GraphQL scalar types for creating precise type-safe GraphQL schemas. ...

    GraphQL Mesh

    GraphQL Mesh — Query anything, run anywhere

    ...The goal of GraphQL Mesh is to let developers easily access services that are written in other APIs specs (such as gRPC, OpenAPI/Swagger, OData, SOAP/WSDL, Apache Thrift, Mongoose, PostgreSQL, Neo4j, and also GraphQL) with GraphQL queries and mutations.GraphQL Mesh gives the developer the ability to modify the output schemas, link types across schemas and merge schema types. You can even add custom GraphQL types and resolvers that fit your needs. It allows developers to control the way they fetch data, and overcome issues related to backend implementation, legacy API services, chosen schema specification and non-typed APIs.

    Collection of TypeScript type challenges with online judge

    type-challenges is a massive set of TypeScript type-level puzzles that turn the compiler into a playground for metaprogramming. Each challenge is a miniature kata where you implement types that transform other types—parsing strings, inferring tuples, mapping unions—without writing any runtime code. Problems are arranged from warm-ups to brain-twisters, letting developers build intuition about distributive conditional types, inference in extends, variance, and other corner cases of the type system. The repository includes tests for each puzzle so you get immediate, compiler-driven feedback when your solution is correct. ...
