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.

Principles of module augmentation


As you saw in the previous chapter, we created specialized modules to do some specific tasks for us. However, as we move forward and develop our application further, we are going to require more functionality from our modules, and we will also require additional specialized modules.

When you are working on a large project, it is quite normal to have many developers working on various pieces of the application. It is also possible to have many developers work on the same part of the application together which requires a seamless approach for combining their efforts and the functionality that they add to the application.

Let's consider our GlobalData module from the previous chapter as an example. This module was responsible for storing and caching application-level data. However, in its current state, it holds a very limited amount of application-level data. It is quite feasible to assume that when different developers are working on other pieces of the application...
