Creating something from nothing

I recently started using Less Css with Django, after using it briefly I found that I did not want to manually compile Less after making changes during development. Using this approach I am able to compile Less client-side during development and have django-compressor compile server-side on live site.

1. Install less via your package manager of choice:

# Using arch linux
sudo pacman -S npm
sudo npm install -g less

# Other distribution
sudo apt-get install npm
sudo npm install -g less

2. Install django-compressor app:

pip install django-compressor

3. Add compressor as installed app:

INSTALLED_APPS = ( 
# other installed apps 
'compressor',

4. Specify less as a precompiler:

COMPRESS_PRECOMPILERS = (
    ('text/less', 'lessc {infile} {outfile}'),
)

5. Add compressor as a static file finder:

STATICFILES_FINDERS = (
# other static files finder
'compressor.finders.CompressorFinder',
)

6. Compiling less

There are many ways to set this up. A simple, yet effective way is to compile less client-side when debugging and server-side during production. To do this we need to do the following:

  1. Download less js file from the Less Website
  2. Create a theme.less (or other name) file
  3. Now your base.html file will be setup something like this: 
    {% load staticfiles %}
{% load compress %}
<!DOCTYPE html>
<html>
<head>
    {% if debug %}
    <link rel="stylesheet" type="text/less" media="all" href="{% static 'less/theme.less' %}" />
    <script src="{% static 'js/less-1.6.1.min.js' %}"></script>
    {% else %}
    {% compress css %}
    <link rel="stylesheet" type="text/less" media="all" href="{% static 'less/theme.less' %}" />
    {% endcompress %}
    {% endif %}
</head>
