Build Your Node.js Application in a Modular Way

Nowadays, almost all web services or integrations are done on top of Node.js run-time. Node.js is a flexible platform with a lot of community support. It is even possible to create documents like xlsx, docx, or pdf directly from Node.js. All major cloud platforms use Node.js as their level 1 language.
Node.js, by design, achieves modularity by using the node_modules structure. All the required modules are stored in a node_modules directory and we can invoke the modules anywhere in our code.
