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


As this was the last phase in the implementation of our application, in this chapter we discussed how we can improve the dependency management and loading of our modules in the browser.

By re-factoring our application's code, we converted our Core submodules to AMD modules and then used RequireJS to load all of our JavaScript files asynchronously from the server.

We saw how we can use RequireJS, which is mainly a script-loading library, to load our AMD and non-AMD modules.

We also covered different formats for defining modules in JavaScript and talked about AMD, CommonJS, and ES6 modules. Since this book is focused on using JavaScript in the browsers, we spent more time getting to know AMD modules, as they are better suited for this purpose.

In our overview of CommonJS and ES6 modules, we noted the similarities between the two formats and saw how ES6 modules can be used in our code.

I hope you have found this book informative and a good introduction to modular programming with JavaScript...
