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.
## 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
```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`
## Use SSL
* Optionally pass in an SSLContext:
```
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)

## Documentation
Sanic's documentation is built using [sphinx](http://www.sphinx-doc.org/en/1.5.1/). Guides are written in Markdown and can be found in the `docs` folder, while the module reference is automatically generated using `sphinx-apidoc`.
To generate the documentation from scratch:
```bash
sphinx-apidoc -fo docs/_api/ sanic
sphinx-build -b html docs docs/_build
```
The HTML documentation will be created in the `docs/_build` folder.
## Warning
One of the main goals of Sanic is speed. Code that lowers the performance of Sanic without significant gains in usability, security, or features may not be merged.
