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 `_. `Source code on GitHub `_ | `Help and discussion board `_. 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 `_), 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() @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!** Documentation ------------- `Documentation on Readthedocs `_.
