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 4. Designing Simple Modules

In this chapter, we are going to focus on applying the concepts that we have learned in the previous chapters to design some simple modules for our application.

We will start by analyzing our application's functionality as a whole and then we will break it down into smaller functional pieces. Once we have decided on our application's functional pieces, we will start creating simple modules to implement the required functionality.

This chapter is meant to demonstrate the possible steps in the beginning of our application's life cycle, based on our requirements. The goal is to see how using modules can help us design a better architecture and get a feel for the practical advantages of a modular design.

The simple modules that we create in this chapter will provide the foundation for our final application in this book, which will be a working client-side single page application.

In this chapter we will cover:

  • Reflecting the overall application requirements in...
