A microframework based on uvloop, httptools, and learnings of flask

Project description

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.

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. 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

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

Documentation

Documentation on Readthedocs.

TODO

  • Streamed file processing

  • File output

  • Examples of integrations with 3rd-party modules

  • RESTful router

Limitations

  • No wheels for uvloop and httptools on Windows :(
