JavaScript Event Factory

A pure JavaScript messaging system that will provide the most common messaging patterns such as Pub/Sub and Observer.

This is currently in development, so use at your own risk.

Pub/Sub Example:

(function() {
  var pubsub = new EventFactory.PublishSubscribe();
  pubsub.createChannel('test');

  pubsub.subscribe('test', function(msg) {
    alert(msg);

    //return pubsub.EVENT_STOP_PROPOGATION;
  });

  pubsub.subscribe('test', function(msg) {
    // Uncomment "return pubsub.EVENT_STOP_PROPOGATION" to see
    alert('This message should be blocked');
  });

  pubsub.publish('test', 'Hello world!');
}());

Observer Example:

(function() {
  var subject = new EventFactory.Observable.Subject();
  var observer = new EventFactory.Observable.Observer();
  
  observer.addListener('Event1', function() {
    alert('Event1 fired!');
  });
  
  observer.addListener('Event1', function() {
    alert('Event1 fired again!');
  });
  
  subject.attach(observer);
  subject.notify('Event1');
  
  subject.detach(observer);
  subject.notify('Event1'); // previous attachments will no longer receive these notifications
}());
