XPJS (Javascript XPCOM) Documentation?

Anyone know where is some usable XPJS, or XPCOM in JS, documentation for recent versions of Firefox/Gecko? And sample code/ tutorials would be great too.

I need to write my own Component, but without .IDL (no C++ compiled interface), so I could access it via

Components.classes['@com.mareksebera/compname;1']
                                .getService().wrappedJSObject;

or this way is not supported anymore? I can't use

Components.classes['@com.mareksebera/compname;1']  
                                .createInstance(Components.interfaces.nsICompName);

Because of missing compiled interface nsICompName

And yes, I know that NSGetModule is deprecated, and I use NSGetFactory and XPCOMUtils.jsm

I know these, but those are not usable with up to date browsers versions

The third link you mentioned is pretty good. Another way to get examples though is to actually download the Mozilla source code and look in the /tests subdirectories. There are some examples there of javascript created XPCOM objects.

One example that comes to mind can be found at:

<mozilla-central>\content\xtf\test\unit

But there are a ton of examples throughout the codebase.

If you prefer you can also browse the code online via mxr.
