# Happens

Super simple and tiny javascript event system.

## Instalation


````shell
# node
npm install happens # --save, --save-dev

# bower
bower install happens # --save, --save-dev

# meteor
meteor add arboleya:happens
````

## API

 - `.on(event, handler)` - listening event
 - `.once(event, handler)` - listening event, once
 - `.off(event, handler)` - unlistening event
 - `.emit(event, handler)` - emitting event

### Basic

````javascript
var Happens = require('happens');

var test = happens();
test.on('init', function(letters){
  console.log('init', letters); // a, b, c
});
test.emit('init', ['a', 'b', 'c'])
````

### With objects

````javascript
var Happens = require('happens');

var obj = happens({
  play: function(){
    this.emit('play');
  }
});
obj.on('play', function(){ console.log('playing'); });
obj.play();
````

### With Classes

````javascript
var Happens = require('happens');

function MyClass() {
  Happens(this);
}

MyClass.prototype.play = function() {
  this.emit('play');
};

var tmp = new MyClass();
tmp.on('play', function(){ console.log('playing'); });
tmp.play();
````

## Meteor

As Meteor doesn't use `require`, worths mentioning that the `Happens`
constructor is directly available on the Client and Server.
