[MediaWiki-l] is there a way to get all js/css module dependencies for a given wikimedia page ?

"all" is a lot, and not likely to be what you want. All includes skinning,
css, userinterface message etc... All have different elements to them that
might not fit your use case, so identifying that is important.
Furthermore, JS and CSS are very dependent on the structure of the page, so
in order to be able to run, you will have to coerce the page to be similar
enough that it will work. They load stuff conditionally for a wide area of
You can retrieve 'some' of the module names that a specific page's content
depends on. These are handy (and also what JS wikitext previews use to
dynamically load modules into the existing context), but far from complete
For Lyon, there actually are none:
The lyon page doesn't depend on JS or CSS modules really. Because
collapsible content is a en.wp specific UI hack on top, delivered by the JS
module 'site' and the CSS module 'site.styles'
Which requires the jquery and mediwiki modules
which require the startup module (the startup module has the mw.loader, the
dependency tree and the configuration):
Remember that load order needs to be ensured, and that the above only
details JS, and not CSS and doesn't help you much there are lazy loaded
modules downloaded over HTTP and everything. Unless you download all
modules and basically implement your own load.php delivery shim to deliver
It's not easy :)
