The lightning-fast ASGI server.
Project description
The lightning-fast ASGI server.
Documentation: https://www.uvicorn.org
Requirements: Python 3.5, 3.6, 3.7
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're 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.
Quickstart
Install using pip:
$ pip install uvicorn
Create an application, in app.py:
class App():
def __init__(self, scope):
assert scope['type'] == 'http'
self.scope = scope
async def __call__(self, receive, send):
await send({
'type': 'http.response.start',
'status': 200,
'headers': [
[b'content-type', b'text/plain'],
],
})
await send({
'type': 'http.response.body',
'body': b'Hello, world!',
})
Run the server:
$ uvicorn app:App
Uvicorn is BSD licensed code.
Designed & built in Brighton, England.
