This repository serves as my personal Node.js learning hub — a place where I’ve documented important backend concepts, patterns, and hands-on examples as I continue mastering Node.js and its ecosystem.

Some of the Node.js concepts included:

• 🧠 Node.js Architecture & Event-Driven Model
• 🌀 Event Loop, Call Stack & Thread Pool
• 🌐 HTTP Module & Building Servers
• 🗂️ Modules — CommonJS & ES Modules
• 📦 npm, package.json & package-lock.json
• 🔐 Environment Variables & dotenv
• 🗄️ File System (fs) Module
• ⚡ Streams & Buffers
• 🧵 Asynchronous Programming (Callbacks, Promises, Async/Await)
• 🗃️ Databases — MongoDB, Mongoose, SQL basics
• 🚏 Express.js (Routing, Middleware, Error Handling)
• 🏗️ MVC Folder Structure
• 🛡️ Authentication — JWT, Bcrypt
• 🚀 Deployment & Production Best Practices
• 🧪 Testing APIs with Postman & Jest
• And more as I keep learning...

Each topic is documented with:

• ✍️ Clear explanations
• 💡 Practical, real-world examples
• 🧩 Clean code snippets
• 🔗 Useful documentation links

The goal of this repo is to build strong backend fundamentals while keeping all essential Node.js knowledge neatly organized and easy to revisit.
