Multiple path specifications in RequireJS

Question

I want to be able to inject extra paths, in a file different from the one which contains the config. Can this be done? A bonus question is whether I can directly access "config" variables.

I understand you ask if it possible to add additional paths after require.config() has been run? — z--

There is no problem with calling require.config multiple times or from multiple places. You don't have to provide an entire set of configuration on subsequent calls. The new path mappings will be merged with existing ones.

For example, if you did this originally:

require.config({
    paths: {
        foomodule: 'libs/foo',
        jquery:  'libs/jquery'
    }
});

You could later do this to provide a different set of paths for jquery and/or to inject paths for a whole new module not present in the original config:

require.config({
    paths: {
        jquery:  [ 'http://code.jquery.com/jquery-2.0.2', 'http://ajax.aspnetcdn.com/ajax/jQuery/jquery-2.0.2' ],
        // note that foomodule not provided here but still keeps its original configuration
        someothermodule: 'some/other/path'
    }
});

Note, however, that if a module was already loaded based on the original config and you wanted to force it to reload from the new config you might have to call require.undef

Regarding the 2nd part of your question (reading the existing config information), I asked a question on this too and so far have not found a way to do it.

It works. For the issue with the optimizer, you just have to add manually those files with include option.
