Uvicorn is a lightning-fast ASGI server implementation, using uvloop and
httptools. Until recently Python has lacked a minimal low-level
server/application interface for asyncio frameworks. The ASGI specification
fills this gap, and means we are now able to start building a common set of
tooling usable across all asyncio frameworks. Uvicorn currently supports
HTTP/1.1 and WebSockets. Support for HTTP/2 is planned.
