ASGI stand for Asynchronous Server Gateway Interface (ASGI), a "spiritual successor to WSGI, intended to provide a standard interface between async-capable Python web servers, frameworks, and applications."

An ASGI app is a a double, asynchronous callable (scope and coroutine). The callable has send and receive awaitables, thus the ability to wait for incoming events and send outgoing events. Events essentially are dictionaries with a predefined format that form the basis of the standard.
