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 7. Base, Sandbox, and Core Modules

So far in this book, we have mostly looked at different techniques for creating and enhancing modules. However, our focus has been on the smaller pieces of the application.

In this chapter, we are going to take a holistic view of our application as a complete functioning body. We will see how its various pieces can be put together to create a robust and flexible ecosystem to deliver our ultimate goal, which is a working Single-Page Application (SPA).

As you read through different sections of this chapter, keep in mind that all the pieces of the application are designed to work together in concert, while still adhering to the principles of maintainability and extensibility of a modular design.

In this chapter, we will cover:

  • Base module and its design

  • Sandbox and the principles behind sandboxing of our components

  • Core and its related modules

  • Components and how they are added to the application

  • Plug-and-play, progressive enhancement, and graceful degradation...
