Discontinued. Please use EventEmitter2 instead. That's what I'm going to do.
#EventEmitter Everywhere… Excelsior!
#Installation npm install common-emitter
The excellent Underscore library is needed for the browser implementation. This is required from within the Common-Emitter code. Using a server like Proxy-Hem or a server that uses Stitch will make it so this is a non-issue. Otherwise, Common-Emitter will check to see if '_' is in the window object so simply load the underscore script first and you should be fine.
