What is it?

Kirby - KRB minifies and combines all assets (both Javascript and Style Sheets) on the fly in one, compressed file.

It uses the excellent minifying library of

  • Less http-requests, good for SEO performance.
  • Less bits and bytes to download.
  • Version control.
  • Extended debugging options.
  • Several MIME-types, one syntax.
  • ...and more!

  • Download the .zip and extract it to site/plugins/krb/.
  • Optionally you can configure some settings in site/config/config.php see the krb-example-config.php.


The KRB syntax looks like the default Kirby syntax when including assets, but's it has some differences;

  echo krb( array('assets/css/error.css',

The krb() function takes these parameters;

  • The assets to be minified / combined (array or singular).
  • The file-type (css, or js).
  • The version number (needed to force re-downloads of cached assets).
  • Minify the assets, or not (defaults to Kirby standard way of including assets).
  • Add cache-control to the query (asset.mime?v=version-number).
  • Show debug-info in the console [F12].

The example above combines / minifies several CSS-assets, adds some cache-control to it and does show debug-info in the console.

  echo krb( 'assets/js/jquery.js',

This example has only one file (js type) to include, version-control 1.4 attached to it and does not minify the (single) asset - while version control and debugging are active.

Wondering what all the shizzle is about? Turn on the debug-parameter, hit [F12] and you'll see the power of minifying and combining all your assets


By default, no config is needed. But you can set your preferences like the one below;

c::set('krb_html_min', false);
c::set('krb_css_path', 'assets/css/my_style.min.css');
c::set('krb_js_path', 'assets/js/my_script.min.js');
c::set('krb_js_async', false);
c::set('krb_js_defer', false);
  • The first parameter also minifies your html output, which is cool - when your code is 100% correct (missing one semi-column ; can corrupt your scripts - so be careful when used).
  • The next two parameters let you override the default minified / combined asset-path.
  • The last two parameters let you set the async and defer option for the final, minified js-output.


  • Like mentioned above, minifying does an excellent job with good codes; but when your (or a third-party) script is not 100% correct, it can be corrupted. Most of the time a semi-column ; is missing between the different functions.
  • Also, turning on the cache or using plug-ins like cachebuster can "corrupt" the functionality of KRB.
  • Be sure to test all, before combining / minifying / etc...

KRB - real time minifying and combining of your assets, with debugging set in config.

You can’t perform that action at this time.
