Modular Programming with JavaScript

Overview of this book

Programming in the modular manner is always encouraged for bigger systems—it is easier to achieve scalability with modular programming. Even JavaScript developers are now interested in building programs in a modular pattern. Modules help people who aren’t yet familiar with code to find what they are looking for and also makes it easier for programmers to keep things that are related close together. Designing and implementing applications in a modular manner is highly encouraged and desirable in both simple and enterprise level applications. This book covers some real-life examples of modules and how we can translate that into our world of programming and application design. After getting an overview of JavaScript object-oriented programming (OOP) concepts and their practical usage, you should be able to write your own object definitions using the module pattern. You will then learn to design and augment modules and will explore the concepts of cloning, inheritance, sub-modules, and code extensibility. You will also learn about SandBoxing, application design, and architecture based on modular design concepts. Become familiar with AMD and CommonJS utilities. By the end of the book, you will be able to build spectacular modular applications in JavaScript.

Application components


Considering that our application is a proof of concept type application, we have only implemented four components; header, footer, content, and notificationWidget (I'm using the component IDs used in the application).

These components are implemented in the following files in the application's project, ImagesInc_Header.js, ImagesInc_Footer.js, ImagesInc_Content.js, and NotificationWidget.js, respectively.

In the following sections, I will provide an overview of each component, but I highly recommend that you have a look at the code accompanying this book to get a better understanding of how these components are implemented.

Keep in mind that our components are modules, which create different application views. In an MVC or MV* architectural pattern paradigm, our components contain their own controllers as well as leveraging the application level controller which has been provided to them through their own instance of SandBox module.

The components also implement their...
