Node.js Modules Explained for Beginners | require() & module.exports | Web Dev Series

Описание: Welcome to the Web Development Series by JDCodebase 🚀

In this video, we learn one of the most important concepts in Node.js — Modules. As applications grow, writing all code in a single file becomes messy and difficult to maintain. Node.js solves this problem using modules, which allow us to split our code into small reusable pieces.

In this beginner-friendly lesson, we will understand how Node.js modules work, how to export and import functionality, and how to build our own custom utility module.

What you will learn in this video:
• What are Modules in Node.js
• Why Modules are Important
• CommonJS Module System
• require() and module.exports
• Exporting Multiple Functions
• Types of Node.js Modules (Core, Local, Third-Party)
• Module Pattern and Private Variables
• Building a Simple Utility Module

These concepts are fundamental for writing scalable Node.js applications and will help you structure your backend projects in a clean and maintainable way.
