cd /home/user/webapp
chmod +x setup.sh
./setup.sh
```

This will:
- Check all prerequisites (Node.js, MongoDB, Redis)
- Install all dependencies
- Set up environment variables
- Start MongoDB and Redis
- Seed the database with 100+ tools
- Start both backend and frontend servers

### Step 2: Access the Application

**Frontend:** http://localhost:8000
**Backend API:** http://localhost:5000
**API Documentation:** http://localhost:5000/api-docs
**Admin Dashboard:** http://localhost:8000/platform/admin.html

### Step 3: Test Login Credentials

**Admin User:**
- Email: `admin@aitoolshub.com`
- Password: `Admin123!@#`

**Regular User:**
- Email: `john.doe@example.com`
- Password: `User123!@#`

## 🛠️ Option 2: Manual Setup

### Prerequisites
```bash
# Check Node.js (requires v18+)
node --version

# Check MongoDB (requires v6+)
mongod --version

# Check Redis (optional, for caching)
redis-server --version
```

### Step 1: Install Dependencies

**Backend:**
```bash
cd /home/user/webapp/backend
npm install
```

**Frontend:**
```bash
cd /home/user/webapp/platform
# Static files, no dependencies needed
```

### Step 2: Configure Environment

```bash
cd /home/user/webapp/backend
cp .env.example .env
```

Edit `.env` with your settings:
```env
NODE_ENV=development
PORT=5000
FRONTEND_URL=http://localhost:8000

# Database
MONGODB_URI=mongodb://localhost:27017/ai-tools-hub

# JWT
JWT_SECRET=your-super-secret-jwt-key-change-this-in-production
JWT_EXPIRE=7d

# Redis (optional)
REDIS_HOST=localhost
REDIS_PORT=6379

# Email (for production)
EMAIL_HOST=smtp.gmail.com
EMAIL_PORT=587
EMAIL_USER=your-email@gmail.com
EMAIL_PASSWORD=your-app-password

# OAuth (optional)
GOOGLE_CLIENT_ID=your-google-client-id
GOOGLE_CLIENT_SECRET=your-google-client-secret
GITHUB_CLIENT_ID=your-github-client-id
GITHUB_CLIENT_SECRET=your-github-client-secret
```

### Step 3: Start Services

**Terminal 1 - MongoDB:**
```bash
# Start MongoDB
mongod --dbpath ~/data/db
```

**Terminal 2 - Redis (optional):**
```bash
# Start Redis
redis-server
```

**Terminal 3 - Seed Database:**
```bash
cd /home/user/webapp/backend
npm run seed
```

**Terminal 4 - Backend:**
```bash
cd /home/user/webapp/backend
npm run dev
```

**Terminal 5 - Frontend:**
```bash

lsof -i :5000

# Kill process
kill -9 <PID>
```

### Redis Connection Issues
