An example of inheriting from event emitter

EventEmitterPattern.js

// Require our emitter

var Emitter = require('events').EventEmitter;

// Our main constructor

var myEmitter = function (config) {
  // extend with emitter
  Emitter.call(this);
  };
  // Inherit from emitter, but keep my constructor
  
  myEmitter.prototype = Object.create(Emitter.prototype, {
    constructor: {
      value: myEmitter
    }
  });
  
  // methods
  
myEmitter.prototype.setName = function (nam) {
  this.name = nam;
  this.emit('nameChanged', name);
 };
 
module.exports = myEmitter;
