Subtopic provides topic-based PubSub for javascript. Originally based on Peter Higgins' port from Dojo to JQuery and updated with support for message chaining inspired by Morgan Roderick's PubSubJS.
Full documentation here: http://pmelander.github.com/Subtopic/
Vanilla javascrip: subtopic.subscribe(topic, callback); subtopic.unsubscribe(topic); subtopic.publish(topic, [payload]);
Underscore: _.subscribe(topic, callback); _.unsubscribe(topic); _.publish(topic, [payload]);
jQuery: .unsubscribe(topic); $.publish(topic, [payload]);
Performance: Check out the official performance comparison here: http://jsperf.com/pubsubjs-vs-jquery-custom-events/50
Topic chaining: To use topic chaining divide your topics using forward slashes e.g. app/region/module/event A subscriber will execute the callback function for the subscribed topic and any sub-topics.
The following publications will each invoke the callback for a subscription to app/region: _.publish("app/region", []); _.publish("app/region/module", []); _.publish("app/region/module/event", []);
