At the Forge - Backbone.js

Write simple MVC applications in JavaScript with Backbone.js.

Backbone.js is one of the smallest and easiest-to-understand MVC frameworks for JavaScript applications. It has become quite popular, as evidenced by the number of blog posts about it in the past few months. The support that its authors, Jeremy Ashkenas and others at DocumentCloud, have offered to many Backbone.js users has been quite impressive to see as well.

Although this column obviously didn't go into great depth about Backbone.js, one shortcoming in this application should have been obvious. What happens when the user wants to store data? Right now, the appointment calendar is not only simple-minded in its interface and execution (for example, there's no way to look at just today's appointments, let alone remove or edit existing ones), but it also fails to provide persistent storage.

Next month, I'll discuss how you can connect a Backbone.js application to a persistent back-end database or server-side MVC application (thus providing an MVC-squared solution), giving users and developers the best of both worlds—flexible development with dynamic JavaScript, but with a robust back end that can persist data easily.
