grunt-django-compressor
A Grunt plugin to iterate over every html file and compress JavaScripts and StyleSheets.
Getting Started
This plugin requires Grunt ~0.4.2
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-django-compressor --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-django-compressor');
The "django_compressor" task
Overview
In your project's Gruntfile, add a section named django_compressor
to the data object passed into grunt.initConfig()
.
grunt.initConfig({
django_compressor: {
my_app_javascript: {
options: {
startTag: '<!--SCRIPTS-->',
endTag: '<!--SCRIPTS END-->',
excludedDirs: [
'node_modules/'
]
},
},
},
});
Important notes
Sample django project
There is a Django project I've created for you to see the grunt-django-compressor
working and I named it superheroes_store, it's basically a super simple application which has a tipically Django structure.
You can clone it in your local machine and do some experiments with the plugin, there is a README which will show you the instructions to install and run it.

{{ DEBUG }} variable
{{ DEBUG }}
variable is used by this grunt plugin to determine when to use uncompressed files (development) and when to use compressed files (production).
You will need to have this variable available in your template, to do that you should have a context_processor
like this:
https://github.com/cristiangrojas/superheroes_store/blob/master/utils/context_processors.py
Keep in mind that you will need to have it in your TEMPLATE_CONTEXT_PROCESSORS
in the settings.py
Testing in local
To test grunt-django-compressor
in your development enviroment you should set DEBUG
to True
in the settings.py
file, then you should run the python manage.py collectstatic
command.
A folder usually called "generated" (depends of your STATIC_ROOT
setting) will be created in your django project folder and there will be all the statics from every application where you have an "static" folder.
You'll also need to serve static files by mapping the static url:
(
r'^static/(?P<path>.*)$',
'django.views.static.serve',
{'document_root': settings.STATIC_ROOT}
),
You can see the full implementation in this file:
https://github.com/cristiangrojas/superheroes_store/blob/master/superheroes_store/urls.py
Options
startTag
Type: String
Default value: <!--SCRIPTS-->
The start tag is an HTML comment to determine where starts your javascript or css importation inside an HTML template of your django project.
endTag
Type: String
Default value: <!--SCRIPTS END-->
The start tag is an HTML comment to determine where starts your javascript or css importation inside an HTML template of your django project.
The startTag
and endTag
tags inside your template should looks something like:
...
<!--SCRIPTS-->
<script src="{{ STATIC_URL }}javascript/libs/jquery/jquery-1.8.3.min.js"></script>
<script src="{{ STATIC_URL }}javascript/libs/jquery-ui/jquery-ui.min.js"></script>
...
<!--SCRIPTS END-->
...
staticFilesPath
Type: String
Default value: ''

destinationFolder
Type: String
Default value: []
DEPRECATED (Aug 22, 2014)
excludedDirs
Type: Array
Default value: ''
An array containing folder names that should be excluded when searching HTML files inside your django project, good examples of folders you should exclude are node_modules
, bower_components
and folders like them.
generateJsSourceMaps
Type: Boolean
Default value: true
Set to true if you want to generate source maps for your compiled js files. Source map files will have exact the same name as the javascript file with the .map extension. Will be also in the same folder (options.destinationFolder).
amazonS3BucketURL
Type: String

Usage Examples
Custom Options
For this example let's suppose we have a Django project called "superheroes_store" and the structure should looks like the following:
superheroes_store/
├── manage.py
├── Gruntfile.js
├── package.json
├── node_modules
│ └── ...
└── superheroes_store
├── __init__.py
├── settings.py
├── static
│ ├── fonts
│ ├── img
│ ├── js
│ └── stylesheets
├── templates
│ └── base.html
├── urls.py
└── wsgi.py
Based on this structure our gruntfile should be:
grunt.initConfig({
django_compressor: {
superheroes_store_javascript: {
options: {
startTag: '<!--SCRIPTS-->',
endTag: '<!--SCRIPTS END-->',
excludedDirs: [
'node_modules/',
]
}
}
},
});
Contributing
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
