How to write an event-causing module with the ability to hang handlers on nodejs?

Question

JavaScript

Throw a link with a tutorial, which describes the creation of a module with a class
when the module is called, a new object is created on the events of which you can hang handlers

as much as I google, but so far I stumble upon only the most primitive articles, and I can’t find a simple module with the necessary functionality to peep the code.
