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>`_.

`Source code on GitHub <https://github.com/sanic-org/sanic/>`_ | `Help and discussion board <https://community.sanicframework.org/>`_ | `User Guide <https://sanicframework.org>`_

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(host='0.0.0.0', port=8000)

Sanic can now be easily run using ``sanic hello.app``.

.. code::

    [2018-12-30 11:37:41 +0200] [13564] [INFO] Goin' Fast @ http://0.0.0.0:8000
    [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.
