Core

Should also be possible and used for sysext. One API for all.

Each extension should register her modules. (Already done in PageRenderer->loadRequireJs() for whole Resources/Public/JavaScript-Folder of each extension).

We have to document that the official supported file structure for extensions is

'EXT:' . $packageName . '/Resources/Public/JavaScript/'

With upper J and S!

As documented in http://docs.typo3.org/typo3cms/TyposcriptReference/Setup/Page/Index.html you can add requireJS the same way:

An example setup can be:

    javascriptLibs {
        requireJs = 1
        requireJs {
            paths {
                jquery = {$page.includePath.javascript}Libs/jquery-1.10.2.min
                theme = {$page.includePath.javascript}Libs/bootstrap.min
            }
            data-main = {$page.includePath.javascript}main
            shim {
                theme.deps {
                    0 = jquery
                }
            }
        }
    }

Define your own location for jquery, add twitter bootstrap and define the main js file as entry point.
Wrap the content of your main as documented on http://requirejs.org

require(['jquery', 'theme'], function($) {
    // youre code
});

No more need to include all of your libs and js files. Just add a "bootstrap" js file that decides which files to load. Each file uses the requirements through requirejs.

It's possible to pass everything to requreJs just by adding it to TypoScript.
Just "paths" and "data-main" will be parsed.

Patch set 2 for branch master of project Packages/TYPO3.CMS has been pushed to the review server.
It is available at https://review.typo3.org/28221

I'd like to have this also backported to 6.1.
