mpneuried / pubsub.coffee
Last active December 10, 2015 23:28
Simple namespaced Pub/Sub coffee class to use as extendable module for NodeJS and the browser.
# # PubSub
#
# Is a small helper to simply realize a pub/sub pattern to a coffee class.
#
# A namespaceing of the topics is also included.
# This means you can subscribe to `a` and also get the `a.b`. But if you subscribe to `a.b` you will not get a `a`.
#
# **required module**: `underscore`
#
