> info **Hint** The `@UsePipes()` decorator is imported from the `@nestjs/common` package.

The `ZodValidationPipe` can be applied to specific parameters and alongside built-in pipes. For example, where we want to validate the route path `id` parameter with the `ParseIntPipe` seperately from the request body:

```typescript
@Put('/:id')
async update(
@Param('id', ParseIntPipe) id: number,
@Body(new ZodValidationPipe(createCatSchema)) body: CreateCatDto
): void {
this.catsService.update(id, body);
}
```

> warning **Warning** `zod` library requires the `strictNullChecks` configuration to be enabled in your `tsconfig.json` file.
