[Answered ]-Webassets in Django

Use django compressor 🙂

To answer your questions however, the filter isn’t the python filter you might be thinking about. It refers to the type of compressor that’s being used – e.g. closure compiler, yui compressor etc.

The idea of any asset manager is to combine, compress and version the static files (js/css and images for some asset managers) so as to optimize web page loading speed. Using one of these asset managers – http://www.djangopackages.com/grids/g/asset-managers/ – leads to page load performance increase with minimal effort (usually only simple configuration is needed)
