Research direction

Start by reviewing the issue’s proposed comparisons with oapi-codegen and fastapi-code-generator, then identify which supported web frameworks and OpenAPI data need interfaces. The work is done when the project has an agreed design and generated type hints and request-handler interfaces that cover validated request bodies, URL parameters, and headers.

Written by the indexing model from the issue text.

Description

Something still missing in all OpenAPI-first implementations I've seen for Python including openapi-core is type-safety w.r.t. the validated request body, URL parameters, and headers. openapi-core validates this data, but there currently is no way to statically type it except for manually implementing the type hints and manually typing the request handlers. This is brittle and doesn't scale well.

I suggest to generate code containing type hints and request handler interfaces for the supported web frameworks similar to oapi-codegen (Golang) or fastapi-code-generator (Python).

The details need to be discussed and figured out, of course, but I'd appreciate some feedback first. What do you think?
