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.

Summary


In this chapter, we had a closer look at our application's implementation and saw how all the pieces fit and work together to create our modular ecosystem, at the code level.

We examined how Core module (our application's controller) was created by leveraging different augmentation techniques and adding sub-modules to MainCore module. This approach allowed us to extend our application's capabilities with ease and in a modular way.

By creating instances of SandBox module, we established communication bridges among the components and the rest of the application while preserving the loose coupling principle of our design.

One important aspect of our application, is the ability to load components dynamically and we discussed how such functionality has been implemented in our Core module.

Using the publish-subscribe and mediator patterns, we created an event handing mechanism which all the pieces of the application can use to communicate with each other. This mechanism was also used in our...
