It's a link shortener service, built by Dustin Moorman for the web, using Node, AngularJS, Express.js, and MongoDB.
A simple RESTful API implemented in Node / Express waits in the background while requests are made via AngularJS to send and retrieve data about URLs held in MongoDB. When a user requests a shortened link, an API call is made to retrieve the associated URL and the user is 302'd to the destination!
Of course! Fork me & create pull requests or issues as much as you'd like.
