ProxyPass /api http://localhost:8000/api
ProxyPassReverse /api http://localhost:8000/api
```

## 🐛 Troubleshooting
### Common Issues
**WebSocket won't connect**
- Check backend CORS settings
- Verify WebSocket URL in .env
- Check browser console for errors
**API calls failing**
- Ensure backend is running
- Check proxy in vite.config.ts
- Verify API_URL in .env
**Build errors**
- Delete node_modules and reinstall
- Clear npm cache: `npm cache clean --force`
- Check Node.js version
