## Migration Notes

When migrating to React TypeScript:

1. **Static LOVs** (STATO_EVENTO, TIPO_PASTO) can be implemented as TypeScript enums or const objects
2. **SQL-based LOVs** should be converted to API endpoints
3. Consider caching strategy for frequently used LOVs (CATEGORIE, TIPI MAT, etc.)
4. TIPO_EVENTO uses Oracle `decode()` function - convert to CASE WHEN or handle in API

### Example TypeScript Implementation

```typescript
// Static LOV - TIPO_PASTO
export const TIPO_PASTO = {
  PRANZO: { value: 'P', label: 'Pranzo' },
  CENA: { value: 'C', label: 'Cena' },
  PRANZO_BUFFET: { value: 'A', label: 'Pranzo Buffet' },
  CENA_BUFFET: { value: 'B', label: 'Cena Buffet' },
} as const;

// Dynamic LOV - API endpoint
// GET /api/lovs/articoli
// GET /api/lovs/categorie
// GET /api/lovs/clienti
// etc.
```
