Template Code Generator

# Use assets/react-app as template base
# Includes: Vite, TypeScript, React Router, standard structure

# Complete API structure with:
# - Route organization
# - CRUD patterns
# - Database models
# - Pydantic schemas

# Production-ready structure:
# - Controllers/Services pattern
# - Middleware setup
# - Error handling
# - Type safety

// Generates complete REST endpoints with validation
router.get('/', controller.getAll);
router.post('/', validate(schema), controller.create);
router.put('/:id', validate(schema), controller.update);
router.delete('/:id', controller.delete);

// Functional component with TypeScript props
export const ComponentName: React.FC<Props> = ({ prop1, prop2 }) => {
  return <div>{/* content */}</div>;
