Sanic is a **Python 3.7+** 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://sanic.readthedocs.io/en/latest/sanic/deploying.html#running-via-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
------------
``pip3 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
$ pip3 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.
.. note::
Windows support is currently "experimental" and on a best-effort basis. Multiple workers are also not currently supported on Windows (see `Issue #1517 <https://github.com/sanic-org/sanic/issues/1517>`_), but setting ``workers=1`` should launch the server successfully.
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'})
if __name__ == '__main__':
app.run()
Sanic can now be easily run 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 3.7. If you need Python 3.6 support, please use v20.12LTS.
