About

This repository showcases various backend projects and experiments built using Node.js. Each folder represents a separate learning module or project, from building basic servers to developing complete RESTful APIs.

---

Technologies Used

• Node.js
• Express.js
• File System Module (fs)
• HTTP Module
• EventEmitter
• JSON & AJAX
• MongoDB (if used)
• Environment variables (.env)
• Middleware
• Error Handling

---

Installation

1. Clone the repository: git clone https://github.com/dev048patel/Node.js.git cd Node.js

2. Install dependencies: npm install

3. Configure environment variables (if applicable): cp .env.example .env

   edit .env with your values

4. Run the project (example): node server.js

   or for specific projects:

   npm run dev

---

Usage

• Explore individual folders for specific projects.
• Each folder contains its own README.md or index.js entry point.
• Example: GET /api/users – fetch users (in Express REST API)

Use Postman or browser to test local endpoints.

Learning Highlights

• Built modular APIs using Express routing
• Created custom servers with http.createServer()
• Used native modules: fs, path, os, and events
• Implemented file reading/writing and JSON parsing
• Learned about middleware, request handling, and response formatting
• Practiced modularizing code and reusability
• Used environment variables and configuration files
• Error handling and logging strategies
