Mercenary is a fully-functioning single-page web application. Bend it to your will and make something beautiful.

On the client side, it uses Backbone with Marionette, LinkedIn's fork of Dust.js for templating, requirejs for dependency injection, LESS for CSS preprocessing, Bower for dependency management, and Grunt as a build and deploy utility. It also takes advantage of the Grunt watcher's live reload capability, which automatically reloads updated CSS files without needing a manual refresh.

On the server side, it uses Express, a popular Node.js application framework. Check it out on Github.
