uvicorn

Uvicorn is an ASGI web server implementation for Python. Until recently Python has lacked a minimal low-level server/application interface for async frameworks. The ASGI specification fills this gap, and means we're now able to start building a common set of tooling usable across all async frameworks. Uvicorn currently supports HTTP/1.1 and WebSockets.

Features

The event loop uvloop will be installed and used if possible
The http protocol will be handled by httptools if possible
Most well established Python Web frameworks started out as WSGI-based frameworks
WSGI applications are a single, synchronous callable that takes a request and returns a response
A strength of the ASGI protocol is that it decouples the server implementation from the application framework
It is run widely in production, and supports HTTP/1.1, HTTP/2, and WebSockets
