Sanic is a Python 3.10+ web server and web framework that’s written to go fast. It allows the usage of the async/await syntax added in Python 3.5, which makes your code non-blocking and speedy.
Sanic is also ASGI compliant, so you can deploy it with an alternative ASGI webserver.

Installation
pip install sanic
Sanic makes use of uvloop and ujson to help with performance. If you do not want to use those packages, simply add an environmental variable SANIC_NO_UVLOOP=true or SANIC_NO_UJSON=true at install time.
$ export SANIC_NO_UVLOOP=true $ export SANIC_NO_UJSON=true $ pip install --no-binary :all: sanic
Hello World Example
from sanic import Sanic
from sanic.response import json
app = Sanic("my-hello-world-app")
@app.route('/')
async def test(request):
return json({'hello': 'world'})Sanic can now be easily run from CLI using sanic hello.app.
