ngraph.events

Small and powerful eventing in node and browser

build status

Example

var eventify = require('ngraph.events');
var yourObject = {}; // any javascript object

eventify(yourObject);

// now any object can listen to events from your object
yourObject.on('beep', function(name) { console.log('Hello ' + name); });

// and you can fire events from your object:
yourObject.fire('beep', 'World!'); // prints 'Hello World!'

// stop listen to events:
yourObject.off('beep');

More advanced examples:

var eventify = require('ngraph.events');
var yourObject = eventify({});

// Pass context to event handler as last argument:
yourObject.on('beep', function () { console.log(this === yourObject); }, yourObject);
yourObject.fire('beep'); // prints true;

// Pass additional arguments to fire:
var onBop = function (x, y) { console.log(x + y); };
yourObject.on('bop', onBop);
yourObject.fire('bop', 40, 2); // prints 42;

// Remove given event handler for 'bop' event
yourObject.off('bop', onBop);

// Remove all event listeners from your object:
yourObject.off();

Why?

I wanted a light-weight eventing library, so I built this.
