Tomas Mikula: Just Import 'N' Go - Spec first APIs without codegen [Scala Days 2025]

Imagine having native support for OpenAPI and/or other API specification languages built into your programming language. By merely importing a specification document, we would obtain a typed interface to a remote service, ready to be used, without the accidental complexity of dealing with HTTP or (de)serialization. Sounds both exciting and scary, right? (Anyone remember xml literals?) I’d rather have a programming language powerful enough to support the above experience as a library. The good news is, Scala is already capable of that today, via its compile-time metaprogramming functionality. In this talk, I’m going to present JING, a new library for spec-first OpenAPI endpoints without codegen. In the first, beginner friendly part, I will show how JING dramatically lowers the barrier to spec-first development against Web APIs and how it facilitates explorative, type-driven programming without unnecessary complexity. Then, I will give a brief peek under the hood and talk about implementation techniques and design decisions. Finally, I’m going to ponder other areas where the JING approach can be applied to unlock a simpler, more productive future. https://github.com/TomasMikula/jing https://continuously.dev/presentation...
