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 implementation


From the beginning, our intent in the design of our application was to create a modularized ecosystem in which different pieces of the code (modules) would be joined together to create a fully functional application. To that end, our code has been structured as displayed in the following screenshot:

As you can see, our application has been organized into three main folders: css which hosts all of our styling files, Images which stores all the images in the application's catalog; and js, which contains all the JavaScript code for our application. As this structure is only one approach to organizing the application's code, you may decide to organize the code differently.

Under js folder, we have organized our JavaScript files further into three main sub-folders; Components which contains the files related to modules that have views associated with them, Modules which contains our modules for the controller and Model of the application, and Widgets which hosts files...
