About ModxMinify

MODX Minify is a MODX Extra to group and minify your CSS, SCSS, LESS and JS files. You can create groups, and each group can contain multiple files of the same type. So for instance you create a group named 'css' where you can add all your css, scss and less files. By calling the MODX Minify snippet inside a tag in your head a minified css file will be generated and cached which will contain all your files grouped and minified!


  • Install the package via Package Management
  • Add groups and files via the manager page
  • Inside your in your template, place the snippet call, for example:

The MODX Minify snippet generates one minified file from all the files added to your specified group. The snippet automatically detects changes in your files, and also checks for changes made in the CMP (adding, updating, removing or reordering of files).

Combining groups

You can also combine multiple groups into one minified file, by using a comma-separated list of groups in your snippet call:

In the above example all the files from group 'css' and 'css2' get combined into one minified CSS file.
