I'm not new to programming, but new to NodeJS. I have a rather complex project that is now several modules deep, of course all rooted in app.js, similar to the following map:

App.js
    requires('Module_a')
    requires('Module_b')
    requires('EventEmitter2');


Module_a.js
    requires('Module_a1');
    requires('Module_a2');

Module_b.js
    requires('Module_b1');
    requires('Module_b2');

I want events generated in Module_a2 to be visible up at app.js and all the way down to Module_b2, and b2 events visible in a2, and so on. How best do I make the same instance of EventEmitter globally visible to all the modules?

Many thanks for your help

It is best not to globalize it, but rather to require your Events module wherever needed. See here for a simple solution: How do you share an EventEmitter in node.js?
