HipChat Atlassian HipChat

Being big Atlassian fans here at Nuxeo, we recently started using HipChat. It's an enterprise chat room. One of the cool things about HipChat is its very simple web API. It makes it really easy to send notifications to a chat room.

To show you how dead easy it is, I did a project showing how to send Nuxeo events to a Hipchat room using their web API. I did it using Nuxeo IDE to generate my plugin structure, using the Nuxeo Plugin Project and Nuxeo Listener wizards. My listener only listens to documentCreated and documentModified events. Each time they occur, we send a small message to a HipChat room, containing the URL of the document, its title, date and creator. The code is really simple (especially because most of it is generated by Nuxeo IDE):

What it does is simply relay the modify or create events to a room. This is the simplest integration possible, but there are many other cool use cases you can implement. You could have a dedicated room per Nuxeo group, you could integrate this with the notification module and send personal notifications, etc. Let us know what you think about this -- are you using the same kind of tools to collaborate? Would like to see integrations between other collaboration tools and Nuxeo?
