Building Backbone.js Apps With Ruby, Sinatra, MongoDB and Haml Introduction In this post we're going to explore writing Backbone.js applications with a Ruby back-end. To assist with this, we're going to use Sinatra – a DSL (domain specific language) for rapidly creating web applications in Ruby.

What Is Sinatra? In the past, you've likely come across or used Ruby on Rails (RoR) – a popular web application framework for the Ruby programming language that helps organize applications using the MVC pattern.
