PyAPI Server is a Python library for serving REST APIs based on OpenAPI specifications. It is based on Starlette and is functionally very similar to connexion, except that it aims to be fully ASGI-compliant.
WARNING: This is still a work in progress and not quite ready for production usage. Until version 1.0 is released, any new release can be expected to break backward compatibility.

from some.path import endpoints
app = Application.from_file("path/to/openapi.yaml", module=endpoints)
