Pyotr [0] is a small library I've been developing for a while, based on Starlette. In a nutshell, it takes an OpenAPI specification and turns it into an API application, taking care of all the routing and validation according to the spec. It is conceptually similar to connexion [1], but it supports async and is Python 3 only. There is also a client component, in the spirit of bravado [2].

This is awesome! I'm one of the community maintainers of connexion (I added openapi 3 support), but I don't have write access to the repo, and it's been really tough to get any changes landed lately. nice work!

Thank you! ^_^

What's the difference from fastAPI? https://fastapi.tiangolo.com/

[hultner]

FastAPI generates specs from code, this generates code from specs

[BerislavLopac]

Just a bit of clarification: Pyotr does not generate any code, it uses the spec as configuration to construct the necessary routes at the app initialization, as well as to validate requests and responses.

Yeah didn't mean literary code generation, Python's dynamic nature makes such steps unnecessary.

In a way it feels kinda lispy (in a good way) to me, data is code, small DSL for working more efficiently with specific domain.
