ASGI Documentation
ASGI (Asynchronous Server Gateway Interface) is a spiritual successor to WSGI, intended to provide a standard interface between async-capable Python web servers, frameworks, and applications.
Where WSGI provided a standard for synchronous Python apps, ASGI provides one for both asynchronous and synchronous apps, with a WSGI backwards-compatibility implementation and multiple servers and application frameworks.
You can read more in the introduction to ASGI, look through the specifications, and see what implementations there already are or that are upcoming.
Contribution and discussion about ASGI is welcome, and mostly happens on the asgiref GitHub repository.
