Combinator Orchard module


An Orchard CMS module that combines and minifies external stylesheets and javascript files to cut down on load times.


  • Combines and minifies css files
  • Combines and minifies javascript files
  • If local and remote resources are mixed (like a local js files with one from a CDN) preserves their original order
  • Preserves conditional resources and minifies (if multiple with the same condition are after each other, also combines) them
  • Can combine remote (CDN) resources
  • Can embed images into stylesheets as data urls
  • Experimental image sprite generation support
  • Resource sets can be defined for better client-side caching: you can create sets of resources that are combined separately (e.g. all jQuery scripts can be in their individual file)
  • Ability to share processed resources between tenants in a multi-tenant application so a set of resources is only processed once, not for every tenant (resource sharing)
  • Busts browser cache when resources are updated (with a query string parameter containing a time stamp)
  • Ability to set custom resource domain
  • Exposing resource processing events
  • LESS and SASS preprocessors, contribution of Onestop Internet, Inc.
  • Command line command for emptying cache ("combinator empty")
  • Info comment in bundled resources about which resources were combined
  • Tuned to be fast
  • With custom IStorageProvider can work in cloud hosting too (if there is no write access to the Media folder anyway)
  • Import/export settings
  • Administration page:
    • Adjust combination exclusion filter
    • Enable/disable combination of CDN resources
    • Set up resource domain
    • Enable/disable minification and adjust exclusion filter
    • Enable/disable image embedding and adjust exclusion filter
    • Enable/disable image sprite generation
    • Define resource sets
    • Enable/disable for admin site
    • Empty cache

The module is also available for DotNest sites.
