Sanic
=================================
|Join the chat at https://gitter.im/sanic-python/Lobby| |Build Status| |PyPI| |PyPI version|
Sanic is a Flask-like Python 3.5+ web server that's written to go fast. It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.
On top of being Flask-like, Sanic supports async request handlers. This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.
Sanic is developed `on GitHub <https://github.com/channelcat/sanic/>`_. Contributions are welcome!
Benchmarks
----------
All tests were run on an AWS medium instance running ubuntu, using 1
process. Each script delivered a small JSON response and was tested with
wrk using 100 connections. Pypy was tested for Falcon and Flask but did
not speed up requests.

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)
SSL Example
-----------
Optionally pass in an SSLContext:
.. code:: python
import ssl
certificate = "/path/to/certificate"
keyfile = "/path/to/keyfile"
context = ssl.create_default_context(purpose=ssl.Purpose.CLIENT_AUTH)
context.load_cert_chain(certificate, keyfile=keyfile)
app.run(host="0.0.0.0", port=8443, ssl=context)
Installation
------------
- ``python -m pip install sanic``
Documentation
-------------
Documentation can be found in the ``docs`` directory.

* Streamed file processing
* File output
* Examples of integrations with 3rd-party modules
* RESTful router
Limitations
-----------
* No wheels for uvloop and httptools on Windows :(
