// Build booking URL
const bookingUrl = buildBookingUrl({
  checkIn: '2024-06-01',
  checkOut: '2024-06-03',
  adults: 2
});

// Build internal URL (relative by default)
const internalUrl = buildInternalUrl({
  checkIn: '2024-06-01',
  checkOut: '2024-06-03',
  guestName: 'Juan Pérez'
});

// Build internal URL with base domain (requires BASE_DOMAIN env var)
const completeInternalUrl = buildInternalUrl({
  checkIn: '2024-06-01',

  checkIn: '2024-06-01',
  checkOut: '2024-06-03'
});
```

## URL Formats

### External Booking URL (Cloudbeds)

Uses hash fragment format:
```
https://hotels.cloudbeds.com/en/reservas/lmKzDQ#checkin=YYYY-MM-DD&checkout=YYYY-MM-DD&currency=eur&adults=N&children=N&roomType=ROOM_TYPE
```

### Internal Project URL

Uses query parameters format:
```
/accommodation/reservations?roomType=ROOM_TYPE&checkIn=YYYY-MM-DD&checkOut=YYYY-MM-DD&adults=N&children=N&guestName=NAME&guestEmail=EMAIL&guestPhone=PHONE
```

Example with room type:
```
/accommodation/reservations?roomType=garden-deluxe&checkIn=2024-01-20&checkOut=2024-01-24&adults=2&children=1&guestName=María%20García%20López&guestEmail=maria.garcia@email.com&guestPhone=+34665789123
```

### Complete URL with Base Domain

Uses configurable base domain with relative paths:
```
https://your-domain.com/custom/path?param1=value1&param2=value2
```

**Environment Variables:**
- `BASE_DOMAIN` (primary) with fallbacks to `MCP_BASE_DOMAIN` or `BOOKING_URL_BASE`
- If not set, defaults to `http://localhost:8080` for development

## Validation Rules

- **Dates**: Must be in YYYY-MM-DD format
- **Date Range**: Check-out must be after check-in
- **Adults**: 1-20 (optional, default: 2)
- **Children**: 0-10 (optional, default: 0)
- **Children=0**: Not included in external URLs

## Error Handling

All functions validate input parameters and throw descriptive errors:

```typescript
// Invalid date format
validateUrlParams({ checkIn: '01/06/2024', checkOut: '2024-06-03' });
// Error: "Formato de checkIn inválido. Use YYYY-MM-DD"

// Invalid date range  
validateUrlParams({ checkIn: '2024-06-03', checkOut: '2024-06-01' });
// Error: "La fecha de salida debe ser posterior a la de entrada"
```

## Testing

Run the test suite:

```bash
npm test
```

The tests cover:
- ✅ Parameter validation with various invalid inputs
- ✅ URL construction with different parameter combinations
- ✅ Environment variable configuration
