Scaling Backbone.js Applications With Marionette.js

Scaling Backbone.js Applications With Marionette.js

Nearly everyone understands how to build a simple JavaScript application these days. From the classic “Todo” JavaScript app, to simple forms-over-data jQuery apps, we’ve all been around that block a few times. With the recent explosion of JavaScript MV* tools and frameworks, though, many of us find ourselves in over our heads, looking at patterns and practices that work well for small applications and pages but fail when scaling to anything substantial.

In this presentation, Derick Bailey will give you an introduction and walk through of many of the patterns and practices that your JavaScript applications need to be scalable. You’ll learn why copying Ruby on Rails’ pattern of “Models”, “Views” and “Controllers” folder names is wrong for scaling JavaScript apps, and how to correct that . You’ll learn about the necessity of separating the various concerns of your application. You’ll learn about patterns that aggregate and coordinate functionality from other parts of the system, how and when to properly decouple disparate areas of your application through messaging patterns, and more. And all of this will be illustrated with Backbone, MarionetteJS and additional plugins and patterns that can give you an edge in creating scalable applications in JavaScript.
