@UsePipes()
Binds one or more pipes to a controller or route handler for transformation and validation.
Syntax
@UsePipes(...pipes: (PipeTransform | Type<PipeTransform>)[])Parameters
| Name | Type | Required | Description |
|---|---|---|---|
pipes | PipeTransform[] | No | Pipe instances or classes applied to all parameters of the scope. |
Returns
ClassDecorator | MethodDecorator — A decorator applied at controller or handler level.
Examples
import { Controller, Post, Body, UsePipes, ValidationPipe } from '@nestjs/common';
@Controller('cats')
export class CatsController {
@Post()
@UsePipes(new ValidationPipe({ whitelist: true }))
create(@Body() dto: { name: string }) {
return dto;
}
}
Notes
Pipes bound with @UsePipes() apply to every argument of the scope. For
application-wide validation prefer app.useGlobalPipes() in main.ts instead
of repeating @UsePipes() on each handler.
