CKFinder on differen domain than app

I'm developing web application based on AngularJS / Node.js. Can I use CKFinder as remote file server for my application (domain different than domein of the web application)?

I can imagine that it should work like this:

var finder = new CKFinder();
finder.basePath = 'http://absolute/path/to/ckfinder/';
finder.popup();
