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 <https://sanicframework.org/en/guide/deployment/running.html#asgi>_.

The project is maintained by the community, for the community. Contributions are welcome!

The goal of the project is to provide a simple way to get up and running a highly performant HTTP server that is easy to build, to expand, and ultimately to scale.

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.

.. code:: shell

   $ export SANIC_NO_UVLOOP=true
   $ export SANIC_NO_UJSON=true
   $ pip install --no-binary :all: sanic

.. note::

If you are running on a clean install of Fedora 28 or above, please make sure you have the redhat-rpm-config package installed in case if you want to use sanic with ujson dependency.

Hello World Example

.. code:: python

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.

.. code::

[2018-12-30 11:37:41 +0200] [13564] [INFO] Goin' Fast @ http://127.0.0.1:8000
[2018-12-30 11:37:41 +0200] [13564] [INFO] Starting worker [13564]

And, we can verify it is working: curl localhost:8000 -i

.. code::

HTTP/1.1 200 OK
Connection: keep-alive
Keep-Alive: 5
Content-Length: 17
Content-Type: application/json

{"hello":"world"}

Now, let's go build something fast!

Minimum Python version is 3.10.
