Pipeline is an asset packaging library for Django.

Project description


Jazzband GitHub Actions Coverage Documentation Status

Pipeline is an asset packaging library for Django, providing both CSS and JavaScript concatenation and compression, built-in JavaScript template support, and optional data-URI image and font embedding.

Django Pipeline Overview


To install it, simply:

pip install django-pipeline


Pipeline compiles and compress your assets files from STATICFILES_DIRS to your STATIC_ROOT when you run Django’s collectstatic command.

These simple steps add Pipeline to your project to compile multiple .js and .css file into one and compress them.

Add Pipeline to your installed apps:


Use Pipeline specified classes for STATICFILES_FINDERS and STATICFILES_STORAGE:



Configure Pipeline:

# The folowing config merges CSS files(main.css, normalize.css)
# and JavaScript files(app.js, script.js) and compress them using
# `yuglify` into `css/styles.css` and `js/main.js`
# NOTE: Pipeline only works when DEBUG is False
        'css_files': {
            'source_filenames': (
            'output_filename': 'css/styles.css',
            'extra_context': {
                'media': 'screen,projection',
        'js_files': {
            'source_filenames': (
            'output_filename': 'js/main.js',

Then, you have to install compilers and compressors binary manually.

For example, you can install them using NPM and address them from node_modules directory in your project path:

    'YUGLIFY_BINARY': path.join(BASE_DIR, 'node_modules/.bin/yuglify'),
# For a list of all supported compilers and compressors see documentation

Load static files in your template:

{% load pipeline %}
{% stylesheet 'css_files' %}
{% javascript 'js_files' %}
