Modules are at the heart of every Node.js application. Here’s how they work:
1️⃣ Built-in Modules:
Node.js comes with modules like:
fs for file handling
http for creating servers
path for file paths
2️⃣ Custom Modules:
Create a module by exporting code:
// myModule.js
module.exports = function greet() {
console.log(“Hello from my module!”);
};
Use it in another file:
const greet = require(‘./myModule’);
greet();
3️⃣ Third-Party Modules:
Install libraries via npm:
npm install express
Import it using require().
The module system ensures clean, maintainable, and scalable applications. What’s your go-to module in Node.js?
