The Muffin

Build Status http://img.shields.io/pypi/v/muffin.svg?style=flat-square

The framework has been created in 2015 when asyncio/aiohttp stack was very young and small. It was an attempt to build a foundation for asyncio web based project with all required tools (plugins system, admin interfaces, REST API and etc). For current moment (2018) aiohttp stack is quite good and the Muffin is depricated. It can be supported because some projects still use it but if you are planning to start a new project I would recomend to have a look on something else.

The Muffin – A web framework based on Asyncio stack (depricated) Muffin is a fast, simple and asyncronous web-framework for Python 3.

Docs are available at https://muffin.readthedocs.org/. Pull requests with documentation enhancements and/or fixes are awesome and most welcome.

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

if __name__ == '__main__':
    app.manage()

Save the script as example.py and run it:

$ python3 example.py run

Open http://localhost:5000, http://localhost:5000/hello/username in your browser. Enjoy!

Plugins

The list of some Muffin plugins (please make PR if you want to provide more):

Requirements

  • python >= 3.5.3

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. You have to specify default configuration module name in your app initialization:

app = muffin.Application('myapp', CONFIG='config.debug')

This name could be overriden by MUFFIN_CONFIG environment variable:

$ MUFFIN_CONFIG=settings_local muffin example run

Which in its turn could be overriden by --config param of muffin command:

$ muffin --config=config.debug example run

Also you can define default config parameter values 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': ...

# Logging options
'ACCESS_LOG': '-',  # File path to access log, - to stderr
'ACCESS_LOG_FORMAT': '%a %l %u %t "%r" %s %b "%{Referrer}i" "%{User-Agent}i"',
'LOG_LEVEL': 'WARNING'
'LOG_FORMAT': '%(asctime)s [%(process)d] [%(levelname)s] %(message)s'
'LOG_DATE_FORMAT': '[%Y-%m-%d %H:%M:%S %z]'

# Setup static files in development
'STATIC_PREFIX': '/static'
'STATIC_FOLDERS': ['static']
Configuring logging

You can define your logging configurations with Python dictConfig format and place in LOGGING conf:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'default': {
            'format': '%(asctime)s %(levelname)s %(name)s %(message)s'
        },
    },
    'handlers': {
        'logfile': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': 'my_log.log',
            'maxBytes': 50 * 1024 * 1024,
            'backupCount': 10
        },
    },
    'loggers': {
        '': {
            'handlers': ['logfile'],
            'level': 'ERROR'
        },
        'project': {
            'level': 'INFO',
            'propagate': True,
        },
    }
}

To use just get logger with logging.getLogger():

import logging
logger = logging.getLogger('project')

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:

async def test_async_code():
    async def coro():
        return True

    assert await coro()

def test_app(app):
    """ Get your app in your tests as fixture. """
    assert app.name == 'my app name'
    assert app.cfg.MYOPTION == 'develop'

async def test_view(client):
    """ Make HTTP request to your application. """
    async with client.get('/my-handler') as resp:
        text = await resp.text()
        assert 'mydata' in text

Also please check aiohttp testing documentation.

Deployment

Use muffin command. By example:

$ muffin example run --workers=4

See muffin {APP} run --help for more info.
