Introduction to Backbone.js Part 5: AJAX – Video Tutorial

Everyone loves AJAX. A few years back it was probably the biggest buzz word in all of web development. Now HTML5 and CSS3 have stolen the show, but AJAX has now taken its place as a first-class citizen among web development - and specifically JavaScript - tools. And to make things even better, Backbone.js has built in support for AJAX and makes it dead simple for you to use it to synchronize your models with a database, as I show in this video tutorial.

JavaScript Design Patterns: Proxy

This is the 9th installment of the JavaScript Design Patterns series and today we’re featuring the Proxy pattern. The word “proxy” can be defined as a substitute, and that essentially explains what a proxy is. A proxy is an object that has the same interface as another object and is used in place of that other object. The only question is why we would use a proxy instead of the original object.

JavaScript Design Patterns: Adapter

Another post, another JavaScript design pattern. This time we’re featuring the Adapter pattern. If you’d like to view the previous posts from this series, you can check out the links at the bottom of this page. This mean, green, fighting machine can transform interfaces. Ok, it doesn’t exactly transform an interface, it really just creates a new object/function that adapts the interface of an existing object/function to match what the code knows how to use.

JavaScript Design Patterns: Bridge

In my last blog post article I discussed the Singleton Design Pattern and how it is used in JavaScript. This time around the Bridge design pattern is poking its head up and asking for a bit of attention, making it the second in the JavaScript Design Patterns series. Every place I’ve read about the Bridge pattern likes to quote the Gang of Four directly in their description of what the Bridge pattern is, so I figure why not me too? The Bridge pattern should “decouple an abstraction from its implementation so that the two can vary independently.” Bridges are quite beneficial in event-driven applications, which are quite common in JavaScript. Considering that fact, it’s surprisingly one of the most underused design patterns.
