📝 Description:
This repository features a collection of Node.js applications that demonstrate backend development fundamentals and advanced patterns. It highlights how to design and build RESTful APIs, integrate databases, manage authentication, and handle asynchronous operations using Node.js best practices.
Each project is crafted to reflect real-world backend systems — from basic CRUD operations to secure APIs with JWT and OAuth. These examples are ideal for learners and professionals looking to deepen their understanding of scalable backend architecture using Express.js, MongoDB, PostgreSQL, and MySQL.
📂 What’s Inside?
🧱 Modular & Scalable Code
Projects follow industry best practices for project structure, folder organization, and code reusability.
🌐 RESTful APIs with Express.js
Well-documented and tested REST API examples with CRUD routes, validation, and middleware logic.
🗄️ Database Integration
Multiple examples showing how to connect and operate with:
MongoDB using Mongoose
PostgreSQL using Sequelize
MySQL using native drivers or ORMs
🔐 Authentication & Authorization
Secure APIs with implementations of:
JWT-based token authentication
OAuth for third-party logins and user management
⏱️ Asynchronous Programming
Efficient use of Promises and async/await for non-blocking I/O operations and clean async code.
