Currently the albatross skin loads around 10 js and 10 css, which is
quite a lot.
We can improve loading time by:
- compression and cache (raffaello will provide Apache configs specific
to XWiki to help for that)
- merging and optimizations of css/js (I've published
http://www.xwiki.org/xwiki/bin/view/Code/MergeCSS to help on that)
- removing unused css/js (now we need to find which one are unused)
- conditional loading of css and js.
This last improvement can help us a lot since some of the css/js are not
even used in view mode, or are only used by a specific panel.
For this my proposal is to add a feature to the core to allow
conditional loading of CSS and JS files.
The current macros in the header would instead of putting CSS and JS add
a placeholder for additional CSS and JS.
Then everywhere where we need these CSS/JS (in a panel, in a wiki page,
in a template) we would call a macro #includecss or #includejs
This macro would add in the context the CSS and JS to add.
At the end of the template rendering the placeholder would be replaced
by the added CSS and JS.
The page would be served.
This would allow to manage the way CSS and JS are added.
WDYT ?
