Sanic
Sanic is a Flask-like Python 3.5+ web server that's written to go fast. It's based off the work done by the amazing folks at magicstack, and was inspired by this article: magic.io/blog/uvloop….
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.
Benchmarks
All tests were run on a 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 | 30,601 | 3.23ms |
| 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
from sanic import Sanic
from sanic.response import json
app = Sanic(__name__)
@app.route("/")
async def test(request):
return json({ "hello": "world" })
app.run(host="0.0.0.0", port=8000)Installation
python -m pip install sanic
Documentation
TODO:
- Streamed file processing
- File output
- Examples of integrations with 3rd-party modules
- RESTful router
Limitations:
- No wheels for uvloop and httptools on Windows :(
