Our First Node.js App: Backbone on the Client and Server. Here at Airbnb, we’ve been looking curiously at Node.js for a long time now.
We’ve used it for odds and ends, such as the build process for some of our libraries, but we hadn’t built anything production-scale. Until now. The Problem There’s a disconnect in the way we build rich web apps these days. In order to provide a snappy, fluid UI, more and more of the application logic is moving to the client.

Rendering Nested Views Backbone.js - Code Hustler. Introduction I’d like to start this post with a disclaimer: this is my first Javascript development so hopefully I won’t say anything silly.
