## Technical Decisions

### Why FastAPI?
✅ Native Python - integrates directly with existing code
✅ Automatic API documentation (Swagger UI)
✅ Built-in WebSocket support
✅ Type safety with Pydantic
✅ High performance (async/await)

### Why React + Vite?
✅ Modern development experience
✅ Fast hot module reloading
✅ TypeScript support out of the box
✅ Large ecosystem of libraries
✅ Component-based architecture

### Why Not Node.js Backend?
❌ Would require rewriting scraping logic
❌ Two languages to maintain
❌ Serialization overhead for IPC
❌ Harder to debug

### Why Tailwind CSS?
✅ Rapid UI development
✅ Consistent design system
✅ Small production bundle
✅ Responsive by default
✅ Dark mode support built-in

---

## Production Deployment

### Option 1: Systemd Service

```bash
sudo systemctl enable media-downloader-api
sudo systemctl start media-downloader-api
```

### Option 2: Nginx Reverse Proxy

```nginx
location /api {
    proxy_pass http://localhost:8000;
}
location /ws {
    proxy_pass http://localhost:8000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
}
```

### Option 3: Build Production Frontend

```bash
cd /opt/media-downloader/web/frontend
npm run build
# Serve from nginx or FastAPI static files
```

---

## Security Considerations

### ⚠️ Current Status: NO AUTHENTICATION

The web interface currently has **no authentication**. It's designed for:
- Local development
- Internal network use
- Behind VPN (Tailscale recommended)
- Localhost only access

### Recommended Security Measures

1. **Use Tailscale VPN**
   - Access via: `http://machine-name.tailscale-machine.ts.net:5173`
   - Built-in authentication
   - Encrypted traffic

2. **Nginx with Basic Auth**
   ```nginx
   auth_basic "Media Downloader";
   auth_basic_user_file /etc/nginx/.htpasswd;
   ```

3. **Firewall Rules**
   ```bash
   sudo ufw allow from 192.168.1.0/24 to any port 8000
   sudo ufw allow from 192.168.1.0/24 to any port 5173
   ```

4. **Future: Add JWT Authentication**
   - User login
   - Session management
   - Role-based access control

---

## Next Steps

### Immediate
1. **Test the interface** - Run `./start.sh` and explore
2. **Trigger a manual download** - Use Platforms page
3. **Watch logs in real-time** - Monitor progress
4. **Edit configuration** - Try changing settings

### Future Enhancements
1. **Authentication** - Add JWT/session auth
2. **User accounts** - Multi-user support
3. **Scheduler control** - Start/stop/configure scheduler
4. **Health monitoring** - Service health dashboard
5. **Analytics** - Advanced statistics and charts
6. **File browser** - Preview downloaded media
7. **Search** - Full-text search across downloads
8. **Notifications** - Browser push notifications
9. **Mobile app** - React Native version
10. **API keys** - For external integrations
