+# 🚀 CI/CD Integration in Node.js with GitHub Actions & VPS (or AWS EC2)
+
+In this repository, we will learn **how to integrate CI/CD** in a Node.js application using **GitHub Actions** and a **VPS server** or **AWS EC2 instance**.  
+We will also learn how to deploy our Node.js application on a VPS server or AWS EC2 instance using a **CI/CD pipeline**.
+
+This is a **step-by-step guide** designed for learning and practicing **CI/CD integration** in real-world Node.js projects using GitHub Actions and remote servers.  
+I created this repository as part of my learning journey, so feel free to explore and adapt it for your own CI/CD needs.
+
+## 📚 Prerequisites
+
+Make sure you know the basics of:
+
+- **Node.js** & **Express.js**
+- **Git** & **GitHub**
+- **AWS EC2** or any **VPS server**
+- CI/CD fundamentals
+- **GitHub Actions**
+- **SSH**
+- **Nginx** server setup
+- **PM2** process manager
+- **MongoDB** (if needed)
+- Basic **environment variables** usage
+- Basic **Linux** commands
+- Basic **terminal** usage
+- Basic **networking** concepts
+- Basic **firewall** setup

+## 🛠️ Setup This Project Locally
+
+### 1. Clone the repository
+
+```bash
+git clone https://github.com/vikashkrdeveloper/CI-CD-Integration-IN-NodeJS.git && cd CI-CD-Integration-IN-NodeJS
+```
+
+### 2. Install dependencies
+
+```bash
+npm install
+```
+
+---
+
+## ▶️ Run The Application Locally
+
+```bash
+npm start
+```
+
+Open your browser and go to:  
+👉 [http://localhost:3000](http://localhost:3000)  
+You should see: **Hello CI/CD World!**
+
+---
+
+## 🌐 Test The API
+
+### Using `curl`
+
+```bash
+curl -X GET http://localhost:3000/
+```
+
+### Using browser
+
+👉 [http://localhost:3000/](http://localhost:3000/)
+
+### Using Postman
+
+Send a `GET` request to `http://localhost:3000/`

+## 🚀 Steps to Integrate CI/CD with GitHub Actions + VPS (or EC2)
+
+1. Create your **Node.js** application
+2. Push the project to **GitHub**
+3. Set up your **VPS** or **AWS EC2** instance
+4. Install on your server:
+   - Node.js
+   - Nginx
+   - PM2
+   - MongoDB (if needed)
+5. Set up **SSH keys** between GitHub Actions and your server
+6. Create a **GitHub Actions workflow** file (`.github/workflows/main.yml`)
+7. Configure the pipeline to:
+   - Install dependencies
+   - Run tests
+   - SSH into server
+   - Pull latest code
+   - Restart app with PM2
+8. Test by pushing a commit — CI/CD should trigger 🚀
+9. Celebrate! Your Node.js app is now automatically deployed! 🎉

+
+## 🏅 Pro Tips
+
+- 🔒 Always use environment variables for sensitive data.
+- 🔥 Use `pm2 status` to monitor your Node.js app in production.
+- 🌐 Set up **Nginx reverse proxy** for serving your app securely.
+- ⚡ Use **fail2ban** or **firewalls** to protect your VPS.
+- 🕵️ Regularly check `pm2 logs` for debugging.
