About ResourceLoader


ResourceLoader was created in 2010 by Roan Kattouw, Trevor Parscal, and Timo Tijhof.

ResourceLoader loads script and style resources on-demand and only for browsers that are capable of running them. Some highlighted features:

Both JavaScript files, CSS files and interface messages are loaded in a single request.
 *  Minifying and concatenating 
 *  This reduces the size of the code, saving bandwidth cost and download time. 

The server can provide multiple module bundles in response to a single request from the browser. These are unpacked in the browser and can be re-used from the cache on subsequent page views, even if they need a different set of modules.
 *  Batch loading and local cache defragmentation 
 *  This reduces the number of requests made. 

A module can contain static files but also generated data from PHP, and virtual files that represent source code from an external source (e.g., a wiki page).
 *  Bundle static files with generated data and virtual files 
 *  This allows granular configuration without overhead of additional API requests.
