## System Requirements

- **Python** 3.8+
- **Node.js** 16+
- **PostgreSQL** 12+ (running locally or accessible)
- **npm** or **yarn**

## Backend Setup

### 1. Install PostgreSQL

Download and install PostgreSQL from https://www.postgresql.org/download/

After installation:
```bash
# Create database
psql -U postgres
CREATE DATABASE ecommerce_db;
\q
```

### 2. Create Virtual Environment

```bash
cd backend

# On Windows
python -m venv venv
venv\Scripts\activate

# On macOS/Linux
python3 -m venv venv
source venv/bin/activate
```

### 3. Install Dependencies

```bash
pip install -r requirements.txt
```

### 4. Configure Environment Variables

Copy `.env.example` to `.env` and update with your database credentials:

```bash
cp .env.example .env
```

Edit `.env`:
```
DATABASE_URL=postgresql://postgres:your_password@localhost:5432/ecommerce_db
JWT_SECRET_KEY=your-super-secret-key-change-this
JWT_ALGORITHM=HS256
ACCESS_TOKEN_EXPIRE_MINUTES=30
FRONTEND_URL=http://localhost:5173
```

### 5. Create Database Tables

```bash
python seed.py
```

This will create all tables and seed sample data including categories, products (with focus on shoes), and test users.

### 6. Run Backend Server

```bash
uvicorn app.main:app --reload --port 8000
```

Server will be available at: `http://localhost:8000`
API documentation: `http://localhost:8000/docs`

## Frontend Setup

### 1. Install Node Modules

```bash
cd frontend
npm install
```

### 2. Configure Environment Variables

Copy `.env.example` to `.env`:

```bash
cp .env.example .env
```

Edit `.env`:
```
VITE_API_URL=http://localhost:8000/api
VITE_APP_NAME=Brand Master
```

### 3. Run Development Server

```bash
npm run dev
```

Frontend will be available at: `http://localhost:5173`

### 4. Build for Production

```bash
npm run build
```

## Troubleshooting

### Backend Issues

**PostgreSQL connection error:**
- Ensure PostgreSQL is running
- Check DATABASE_URL in .env
- Verify username and password

**Import errors:**
- Make sure virtual environment is activated
- Run `pip install -r requirements.txt` again

### Frontend Issues

**API not responding:**
- Check backend is running on port 8000
- Check VITE_API_URL in .env

**Port already in use:**
```bash
# Find and kill process on port
# On Windows
netstat -ano | findstr :5173
taskkill /PID <PID> /F

# On macOS/Linux
lsof -ti:5173 | xargs kill -9
```

## Development Notes

- Backend is built with **FastAPI** for high performance
- Frontend uses **React** with **Vite** for fast development
- **SQLAlchemy** handles database operations
- **JWT** for secure authentication
- **CORS** enabled for frontend-backend communication
- All responses follow RESTful API standards

## Production Deployment

For production:
1. Set DEBUG=False in backend config
2. Use a production database server
3. Configure proper CORS settings
4. Use environment-specific .env files
5. Deploy frontend as static assets
6. Use a production WSGI server (Gunicorn)
7. Set up HTTPS/SSL certificates
