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 moved from the conceptual design of modules to the practical aspects of implementing them. We started by looking at the high-level requirements of our intended application, and then considered the kind of modules that we might possibly need to fulfill those requirements.

We briefly discussed the MV* design pattern and structured our application to follow this pattern. Then, based on the functionality and the role that our modules play in our design, we categorized them to be part of the controller, view or model pieces of our application.

The view for our application was generated by first creating an index.html page skeleton and then populating its main fragments based on object definitions, using a core module.

We also created a safe global data repository for our application to act as the model piece of our architecture.

An example of how modules can collaborate together to complete tasks and provide application level functionality was also presented.
