An implementation of the observer design pattern.
Tested Platforms: V8 (Node)
npm install observer
To create an observation table: var EventBroker = require('observer').EventBroker;
var events = new EventBroker;
events.create('foobar');
events.subscribe('foobar', console.log.bind(console,'observer#1:') );
events.subscribe('foobar', console.log.bind(console,'observer#2:') );
events.publish('foobar',3,14);
// => observer#1, 3, 14
// => observer#2, 3, 14
To create an observable class: var Observable = require('observer').Observable, inherits = require('util').inherits;
function Foobar(){
Observable.call(this);
this.create('qux');
}
var f = new Foobar();
f.on('qux', console.log.bind(console, 'observer#3:');
f.events.publish('qux',3,14);
// => observer#3, 3, 14
