django-shrink

A js compiler & css minifier with sass compatibility

Requirements

• Django 1.3+
• 2.6 <= Python < 3
• Java for compiling and compressing
• django.contrib.staticfiles in INSTALLED_APPS

Installation

pip install django-shrink

Configuration

INSTALLED_APPS = (
    ...
    'django.contrib.staticfiles',
    ...
    'shrink',
    ...
)

Optionally if you want to use Sass you need to add the compilation view to your urls:

# urls.py
urlpatterns = patterns('',
    ...
    (r'', include('shrink.urls')),
    ...
)

Usage

Define your javascripts and css files in your template as in this example:

{% load shrink %}
{% styles css/myproject-min.css %}
    css/reset.css
    css/forms.css
    css/myproject.scss
{% endstyles %}
{% scripts js/myproject-min.js %}
    js/jquery.js
    js/plugin.js
    js/myproject.js
{% endscripts %}

When DEBUG = True this will end up as:

<link rel="stylesheet" href="{{ STATIC_URL }}css/reset.css">
<link rel="stylesheet" href="{{ STATIC_URL }}css/forms.css">
<link rel="stylesheet" href="{{ STATIC_URL }}css/myproject.scss">
<script src="{{ STATIC_URL }}js/jquery.js"></script>
<script src="{{ STATIC_URL }}js/plugin.js"></script>
<script src="{{ STATIC_URL }}js/myproject.js"></script>

When DEBUG = False this will end up as:

<link rel="stylesheet" href="{{ STATIC_URL }}css/myproject-min.css?timestamp">
<script src="{{ STATIC_URL }}js/myproject-min.js?timestamp"></script>

When deploying you want to compile your javascripts, compile your scss (Sass) and compress the css files. django-shrink overrides the collectstatic management command and after collecting the static files it does the compiling and compressing. Thus you need to execute the management command collectstatic in your deployment environment.
