bubPubSub (VisualWeb's PubSub) is a publish/subscribe system for communication between objects/modules of your code. It's rather similar to common pubSub systems, but closer related to the event system of nodeJS or the browser. USP's are
(optional) BUBBLING along a topic-tree
(optional) PERSISTENCE of publications for later retrieval/reference
It is developed, used and sponsored by myLinkCloud (http://www.mylinkcloud.com), meinUnterricht (http://www.meinUnterricht.de), K.lab (http://www.klab-berlin.com), and ViSERiON (http://www.viserion.com) .
bubPubSub works on both ends, the client and the server (nodeJS).
Installation with nodeJS
$ npm install bubpubsub
cd to node_modules/bubpubsub make
