jQuery Design Patterns

By: Thodoris Greasidis

Overview of this book

jQuery is a feature-rich JavaScript library that makes HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a variety of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. jQuery solves the problems of DOM manipulation, event detection, AJAX calls, element selection and document queries, element attribute and data management, as well as object management utilities. This book addresses these problems and shows you how to make the best of jQuery through the various design patterns available. The book starts off with a refresher to jQuery and will then take you through the different design patterns such as facade, observer, publisher/subscriber, and so on. We will also go into client-side templating techniques and libraries, as well as some plugin development patterns. Finally, we will look into some best practices that you can use to make the best of jQuery.

Introducing the Facade Pattern

The Facade is a structural software design pattern that deals with how abstractions of the various parts of an implementation should be created. The key concept of the Facade Pattern is to abstract an existing implementation and provide a simplified API that better matches the use cases of the developed application. According to most Computer Science bibliographies describing this pattern, a Facade is most commonly implemented as a specialized class that is used to segment the implementation of an application into smaller pieces of code, while providing an interface that completely hides the encapsulated complexity. In the web development world, it is also common to use plain objects or functions for the implementation of a Facade, taking advantage of the way in which JavaScript treats functions as objects.

In applications that have a modular structure, like the examples of the previous chapter, it is also common to implement Facades as separate modules with...
