## 📋 Prerequisites

- **Node.js** (v18+)
- **npm** (v9+)
- **Git** (v2+)
- **Docker** & **Docker Compose**
- **MongoDB** (local or Atlas)

---

## 🚀 Installation

### 1. Clone the Repository

```bash
git clone https://github.com/BaoHo205/Smart-Library-Platform.git
cd Smart-Library-Platform

2. Start Docker Services (Database)

First, start the Docker services for the databases:

# Navigate to backend directory
cd backend

# Start Docker services (MySQL with Flyway migrations)
docker-compose up -d

# Verify containers are running
docker-compose ps

This will start:

• MySQL Server on port 6446 (mapped from container port 3306)
• Flyway Migration Service to set up the database schema automatically

3. Install Dependencies

# Install backend dependencies (if not already in backend directory)
cd backend
npm install

# Install frontend dependencies
cd ../frontend
npm install

4. Environment Configuration

Copy the sample environment file and configure your settings:

# Copy environment sample (backend)
cd backend
cp .env.sample .env

# Edit with your actual values
nano .env  # or use your preferred editor

Configure both database connections in your backend/.env file:

# Backend Configuration
PORT=5000
NODE_ENV=development
APP_NAME="Smart Library Platform Backend"
APP_VERSION=1.0.0

# MongoDB Configuration (with Connection Pool)
MONGODB_URI=mongodb+srv://username:password@cluster.mongodb.net/?retryWrites=true&w=majority&appName=Cluster0
# Or local: mongodb://localhost:27017/library-platform

# MySQL Configuration (Dockerized Database)
MYSQL_HOST=localhost
MYSQL_PORT=6446
MYSQL_USER=root
MYSQL_PASSWORD=ftech2005
MYSQL_DATABASE=library_platform

# JWT Configuration
JWT_SECRET=your-super-secret-jwt-key-min-32-characters-long
JWT_EXPIRE=7d
JWT_COOKIE_EXPIRE=7

# CORS Configuration
CORS_ORIGIN=http://localhost:3000,http://localhost:3001
CORS_CREDENTIALS=true

5. Database Setup

MongoDB Setup

# For development, you can use MongoDB Atlas (recommended)
# Update MONGODB_URI in your .env file with your Atlas connection string

# Or start MongoDB locally (if using local installation)
mongod

MySQL Setup (Dockerized)

The MySQL database is already running in Docker from step 2. The Docker setup includes:

• MySQL Server: Running on port 6446
• Database: library_platform (auto-created)
• User: root with password ftech2005
• Flyway Migrations: Automatically applied on startup

To verify the database is working:

# Connect to the dockerized MySQL database
mysql -h localhost -P 6446 -u root -pftech2005 library_platform

# Or check tables
mysql -h localhost -P 6446 -u root -pftech2005 -e "SHOW TABLES;" library_platform

🎮 Usage

Development Mode

Step 1: Ensure Docker services are running

cd backend
docker-compose ps  # Check if containers are running
# If not running: docker-compose up -d

Step 2: Start the backend server

# Terminal 1: Backend (make sure you're in backend directory)
cd backend
npm run dev

Step 3: Start the frontend

# Terminal 2: Frontend (in a new terminal)
cd frontend
npm run dev

Access the Application

• Frontend: http://localhost:3000
• Backend API: http://localhost:5000
• API Health Check: http://localhost:5000/
• MySQL Database: localhost:6446 (user: root, password: ftech2005)

Expected Output

When starting the backend, you should see:

🚀 Starting Smart Library Platform Backend...
✅ Connected to MongoDB successfully!
✅ Connected to MySQL successfully!
📋 App: Smart Library Platform Backend
🎉 Server running at http://localhost:5000
