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.
+-----------+-----------------------+----------------+---------------+
| Server | Implementation | Requests/sec | Avg Latency |
+===========+=======================+================+===============+
| Sanic | Python 3.5 + uvloop | 33,342 | 2.96ms |
+-----------+-----------------------+----------------+---------------+
| Wheezy | gunicorn + meinheld | 20,244 | 4.94ms |
+-----------+-----------------------+----------------+---------------+
| Falcon | gunicorn + meinheld | 18,972 | 5.27ms |
+-----------+-----------------------+----------------+---------------+
| Bottle | gunicorn + meinheld | 13,596 | 7.36ms |
+-----------+-----------------------+----------------+---------------+
| Flask | gunicorn + meinheld | 4,988 | 20.08ms |
+-----------+-----------------------+----------------+---------------+
| Kyoukai | Python 3.5 + uvloop | 3,889 | 27.44ms |
+-----------+-----------------------+----------------+---------------+
| Aiohttp | Python 3.5 + uvloop | 2,979 | 33.42ms |

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)
Installation
------------
- ``python -m pip install sanic``

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