Hello.

In a recent project building a web push service I wanted to have my UI respond to application level events (semantically if you will) because there were a couple of components that require information from the system but are not dependent with each other and I wanted them to be able to manage themselves independently of the ‘business logic’. I looked around at lots of different tools to help me, but because I frequently have a heavy case of NIH syndrome and the fact that I think people can implement their own infrastructural elements pretty quickly, I decided to quickly knock-up a simple client-side PubSub service — it worked pretty well for my needs.
