Question

Are there any best practices or common solutions to adding support for “static” methods and variables to MooTools-generated classes?

In particular, is there any solution that ensures that static initialization takes place before the instance initialize method is called?

Answer 1

Caveat: Never used MooTools. I’ve used Prototype a fair bit, though, which has a similar Class system (MooTools is either “inspired by” or a fork of Prototype, depending on who you ask).

Just add them as properties on the resulting “class”:

var MyClass = new Class(properties);
MyClass.staticMethod = function() {
    // ...
};

(The first line above is from the docs; the remainder is my addition.)

You know that will happen prior to initialize on any new instance because you’re not leaving an opportunity for creating a new instance prior to attaching your static methods (or properties).
