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.

Chapter 10. Enterprise Grade Modular Design, AMD, CommonJS, and ES6 Modules

In this last chapter of the book, we are going to mainly focus on re-factoring some of our application modules so we can have a more robust way of loading and managing them.

The title of this chapter mentions Enterprise Grade, but in fact we can use the principles discussed here for applications of any size and type. In the next sections, I'll introduce you to various approaches for creating and loading modules in JavaScript and talk about the environments that each approach might be better suited for. You'll also see how we can manage our module dependencies in a more structured manner.

Keep in mind that this chapter is meant to be only an introduction to such techniques, but hopefully it will make you curious enough to research them further.

I believe after seeing their benefits, you'll consider these modular design implementations in your future projects.

Some of the topics that we will cover in this chapter are:
