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.

In this chapter, we learned what a Facade actually is. We learned its philosophy and the uniform way in which it defines how code abstractions should be created so that they are easily understandable and reusable by other developers.

Starting from the simplest use cases of this pattern, we learned how to wrap a complex API with a Facade and expose a simpler one that is focused on the needs of our application and is a better match to its specific use cases. We also saw how jQuery embraces the concepts of this pattern in its implementation and how providing simple APIs for more basic web-developing techniques, such as DOM Traversals, played a critical role for its wide adoption.

Now that we have completed our introduction to how the Facade Pattern can be used to decouple and abstract parts of an implementation, we can move on to the next chapter where we will be introduced to the Builder and Factory Patterns. In the next chapter, we will learn how to use these two Creational Design Patterns...
