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.

Using CDNs

Instead of serving all of the JavaScript and CSS files of the third-party libraries from your web server, you should consider using a Content Delivery Network (CDN). Using a CDN to serve the static files of the libraries that are used by your website can make it load faster since:

  • CDNs have high speed connections and several caching levels.

  • CDNs have many geographically distributed servers that can deliver the requested files faster since they are closer to the end user.

  • CDNs help parallelize resource requests, since most browsers can only download up to four resources concurrently from any specific domain.

Moreover, if a user has static resources cached from a previous visit to another website that uses the same CDN, he or she will not have to download them again, reducing the time that your site needs to load.

Below is a list with the most widely used CDNs for JavaScript libraries which you can use in your implementations:
