BáiZé

Powerful and exquisite WSGI/ASGI framework/toolkit. Only relies on the standard library.

The minimize implementation of methods required in the Web framework. No redundant implementation means that you can freely customize functions without considering the conflict with baize's own implementation.

Under the ASGI/WSGI protocol, the interface of the request object and the response object is almost the same, only need to add or delete await in the appropriate place. In addition, it should be noted that ASGI supports WebSocket but WSGI does not.

Type annotations as strict as possible (almost no Any)
Support range file response, server-sent event response
Support WebSocket (only ASGI)
WSGI, ASGI routing to combine any application like Django(wsgi)/Kuí(wsgi)/Pyramid/Bottle/Flask or Django(asgi)/Kuí(asgi)/Starlette/FastAPI/Sanic/Quart

Install

pip install -U baize
