Overview

This repository showcases a learning journey through Node.js development, progressing from basic concepts to a production-ready URL shortening service with user authentication. Each project builds upon the previous one, demonstrating mastery of increasingly complex topics.

Projects

Hello World

A minimal Node.js application demonstrating core concepts.

Features:

• Basic Node.js setup with npm
• Using built-in os module to access system information

---

Project 01 - Hybrid Node Server

A RESTful API server demonstrating best practices for building hybrid applications that serve both web browsers and API clients.

Features:

• Hybrid server architecture (SSR for browsers, JSON for APIs)
• Express.js middleware implementation
• MongoDB integration with Mongoose ODM
• MVC (Model-View-Controller) pattern
• Request logging middleware

Tech Stack:

• Node.js, Express.js
• MongoDB, Mongoose
• dotenv for environment configuration

API Endpoints:

Method	Endpoint	Description
GET	/api/users	Get all users
GET	/api/users/:id	Get user by ID
POST	/api/users	Create new user
PATCH	/api/users/:id	Update user
DELETE	/api/users/:id	Delete user

Project 04 - URL Shortener with JWT Auth

A full-featured URL shortening service with user authentication and click analytics.

🔗 Live Demo: url-shotener-advanced.onrender.com

Features:

• URL shortening with custom short IDs
• Instant redirection to original URLs
• Click analytics and visit tracking
• User signup/login with JWT authentication
• Role-based access control (NORMAL, ADMIN)
• Rate limiting for API protection
• Server-side rendering with EJS templates
• Auto-expiring URLs (TTL: 24 hours)

Tech Stack:

• Node.js, Express.js
• MongoDB with Mongoose
• JWT for stateless authentication
• EJS templating engine
• cookie-parser, express-validator
• nanoid/uuid for short ID generation

API Endpoints:

Method	Endpoint	Description	Auth
POST	/url	Create shortened URL	Required
GET	/url/:shortId	Redirect to original URL	-
GET	/analytics/:shortId	Get click analytics	Required
POST	/user/signup	Register new user	-
POST	/user/login	User login	-

Key Learnings

Concepts Covered

• Node.js Fundamentals - Event loop, modules, npm
• Express.js - Routing, middleware, error handling
• MongoDB/Mongoose - Schema design, CRUD operations, indexing
• Authentication - JWT tokens, cookies, stateless auth
• Security - Rate limiting, input validation, role-based access
• Architecture - MVC pattern, RESTful API design, hybrid servers
• SSR - Server-side rendering with EJS templates

RESTful API Guidelines

See REST-Rules.md for detailed RESTful API best practices followed in these projects.

Key Principles:

1. Use proper HTTP methods (GET, POST, PATCH, PUT, DELETE)
2. Design hybrid servers:
   • /users → Render HTML (SSR) for browsers
   • /api/users → Return JSON for mobile/frontend apps
