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.

Chapter 5. The Facade Pattern

In this chapter, we will showcase the Facade Pattern, a structural design pattern that tries to define a uniform way regarding how developers should create abstractions in their code. Initially, we will use this pattern to wrap complex APIs and expose simpler ones that focus on the needs of our application. We will see how jQuery embraces the concepts of this pattern in its implementation, how it achieves encapsulating complex implementations that are integral parts of the web developer's tool-belt into easy-to-use API's, and how this plays a critical role for its wide adoption.

In this chapter, we will:

  • Introduce the Facade Pattern

  • Document its key concepts and benefits

  • See how jQuery uses it in its implementation

  • Write an example implementation where Facades are used to completely abstract and decouple a third-party library
