Show HN: OpenAPI-TypeScript-server – Codegen TypeScript servers from OpenAPI

I really want the ergonomics of schema-first development from gRPC, combined with the ubiquity of OpenAPI. I couldn't quite find anything I really liked off-the-shelf for node + TypeScript, so I wrote one. It's largely modeled off of https://github.com/oapi-codegen/oapi-codegen for Go.

I've always been excited about OpenAPI and schema-first development, but I'm betting that these artifacts will be extra important in the era of coding agents. Giving the LLM one place to see your entire domain feels like a good way to accelerate the value of these tools. And good for humans, too!

I'm looking for early feedback, suggestions for other projects to look at, moral support, "this is a bad idea" kind of discouragement if necessary, etc.
