Project description
The Muffin
The Muffin – A web framework based on Asyncio stack (early beta)
Muffin is a fast, simple and asyncronous web-framework for Python 3.
Example “Hello User” with the Muffin:
import muffin
app = muffin.Application('example')
@app.register('/', '/hello/{name}')
def hello(request):
name = request.match_info.get('name', 'anonymous')
return 'Hello %s!' % name
Save the script as example.py and run it:
$ muffin example run
Open http://fuf.me:5000, http://fuf.me:5000/hello/username in your browser. Enjoy!

Benchmarks
You could find some tests here: http://klen.github.io/py-frameworks-bench/
Installation
The Muffin should be installed using pip:
pip install muffin
Usage
See more in the example application sources. The application is deployed on Heroku: https://muffin-py.herokuapp.com
Run example server locally:
$ make -C example run
And open http://fuf.me:5000 in your browser.
Configuration
Muffin gets configuration options from python files. By default the package tries to load a configuration from config module (config.py).
There are few ways to redifine configuration module:
Set configuration module in your app initialization:
app = muffin.Application('myapp', CONFIG='config.debug')Set environment variable MUFFIN_CONFIG:
$ MUFFIN_CONFIG=settings_local muffin example run
Also you can define any options while initializing your application:
app = muffin.Application('myapp', DEBUG=True, ANY_OPTION='Here', ONE_MORE='Yes')
Base application options
Base Muffin options and default values:
# Configuration module 'CONFIG': 'config' # Enable debug mode 'DEBUG': False # Logging options 'LOG_LEVEL': 'WARNING' 'LOG_FORMAT': '%(asctime)s [%(process)d] [%(levelname)s] %(message)s' 'LOG_DATE_FORMAT': '[%Y-%m-%d %H:%M:%S %z]' # List of enabled plugins 'PLUGINS': [] # Setup static files in development 'STATIC_PREFIX': '/static' 'STATIC_FOLDERS': ['static']
CLI integration
Run in your shell:
$ muffin path.to.your.module:app_object_name --help
Write a custom command
@app.manage.command
def hello(name, upper=False):
""" Write command help text here.
:param name: Write your name
:param upper: Use uppercase
"""
greetings = 'Hello %s!' % name
if upper:
greetings = greetings.upper()
print(greetings)
$ muffin example hello --help
Write command help text here.
positional arguments:
name Write your name
optional arguments:
-h, --help show this help message and exit
--upper Enable use uppercase
--no-upper Disable use uppercase
$ muffin example hello mike --upper
HELLO MIKE!
Testing
Setup tests
Set module path to your Muffin Application in pytest configuration file or use command line option --muffin-app.
Example:
$ py.test -xs --muffin-app example
Testing application
See examples:
import pytest
@pytest.mark.async
def test_async_code():
from aiohttp import request
response = yield from request('GET', 'http://google.com')
text = yield from response.text()
assert 'html' in text
def test_app(app):
""" Get your app in your tests as fixture. """
assert app.name == 'my app name'
assert app.cfg.MYOPTION == 'develop'
def test_view(client):
""" Make HTTP request to your application. """
response = client.get('/my-handler')
assert 'mydata' in response.text
Deployment
Use muffin command. By example:
$ muffin example run --workers=4
See muffin {APP} run --help for more info.
