🐛 Troubleshooting

Build Errors

If you see TypeScript errors about unused variables:

# Check for unused imports
npm run lint

API Connection Issues

Make sure the backend is running on port 8000, or update the proxy in vite.config.ts.

CORS Errors

The Vite dev server proxies /api requests to the backend. For production, ensure CORS is configured on the backend.
