- Since MediaWiki 1.26, gadgets are now required to use ResourceLoader - see ResourceLoader/Migration guide (users) for more details.
- → See ResourceLoader/Features for a complete walk through of ResourceLoader
ResourceLoader solves this problem by loading resources on-demand and only for browsers that can run them. Although there is much more to it, the overall flow for client-side performance can be summarized by these 3 points:
- Minifying and concatenating
→ which reduces the code's size and parsing/download time
- Batch loading
→ which reduces the number of requests made
- Data URI embedding
→ which further reduces the number of requests, response time and bandwidth
Optionally images referenced in stylesheets can be embedded as data URIs. Together with the gzipping of the server response, those embedded images, together, function as a "super sprite".
