What is the role of the module.exports object in Node.js?

Question

Aryan Kumar · Answer

In Node.js, the module.exports object plays a central role in defining and exporting code from one module (a JavaScript file) to be used in another module. It is a fundamental part of the CommonJS module system used in Node.js. Here's a human-readable explanation of the role of the module.exports object:
Exporting Code: module.exports is an object that is initially empty when a module is created. You can add properties and methods to this object to specify what you want to make available for other modules to use.Exporting Functions and Variables: You can assign functions, variables, or objects to
module.exports. These will become accessible to other modules that
require this module.Simplifying Import: When you require a module in another file, you can assign the imported values directly to a variable. This allows you to use the exported functionality in your code.Default Export: You can set module.exports to a single value directly, effectively making it the default export of the module. This can be useful when you want to export a single function or object as the primary functionality of your module.
In summary, the module.exports object in Node.js serves as a way to define what parts of a module are accessible from other modules. It allows you to encapsulate code and functionality within separate files, promoting modularity and code organization in your Node.js applications. When you require a module in another file, you can access the exported values and use them in your code.
