Understanding Node.js Module Export Patterns

🚀 Understanding Module Export Patterns in Node.js In Node.js, modules help us organize our code into reusable pieces. Knowing how to export and import them is essential for clean, maintainable projects. Here are some common patterns 👇 🔹 1️⃣ Single Export Use this when your module exposes one main function or object: module.exports = add; 🔹 2️⃣ Multiple Exports Export multiple functions or constants as an object: module.exports = { add, subtract }; 🔹 3️⃣ Using exports shorthand Attach methods directly to the exports object: exports.sayHello = () => 'Hello!'; ⚠️ Don’t reassign exports directly — it breaks the reference. 🔹 4️⃣ ES Module Syntax (Modern Way) With "type": "module" in your package.json: export function add(a, b) { return a + b; } export default function multiply(a, b) { return a * b; } --- 💡 Tip: For modern projects, prefer ES Modules — they’re cleaner and work seamlessly with modern tooling. #NodeJS #JavaScript #BackendDevelopment #WebDevelopment #CodingTips #Developers
