  • Meet Volt, A Promising Ruby Framework For Dynamic Applications (Publication)
    In an attempt to make web applications a lot more dynamic, front-end Javascript frameworks like Angular.js, Backbone.js and Ember.js have gained a lot of popularity. However, these frameworks often require a back-end application to be useful, so they are used in conjunction with web frameworks like Ruby on Rails and Django. On the other hand, Volt is capable of managing the back-end and a dynamic front-end; since both functionalities are tightly integrated into its core.
