Source Code

Source code is prepared using Browserify which is also compatible with Node.JS. There is a UMD bundle which can be used with AMD or a vanilla browser (where it will export a global called called addEvents.

Example

var MyClass = function() {
};

MyClass.prototype.doSomething = function() {
	return this._emit('doneit','a','b');
};

addEvents(MyClass,['doneit']);

var myClass = new MyClass();
myClass.on('doneit',function (a, b) {
	console.log('a = ' + a + ', b = ' + b);
});

myClass.doSomething();
