Show HN: Fastify-zod, type-once, run everywhere (TypeScript/OpenAPI)

Oh to be clear: I don’t mean that the end user will be expected to write JSON Schema. In all likelihood most users never will. Instead they’d use an interface quite like zod or io-ts, it’s the core library and base types that are defined with JSON Schema. And of course that will be available to end users if the core library does not cover their particular use case.
