parse params and

is there a way to specify that Params and Query be injected as a number instead of a string?

@Get("validate/:code?")
codes(@Param("code") code : number) {
	return ValidationService.validate(number); // error: currently gets passed as a string
}

I know I can use parseInt(code) but i am wondering if there is a more elegant way of specifying to the injector to return the param as a number.

Usage example https://github.com/nestjs/nest/blob/master/sample/01-cats-app/src/cats/cats.controller.ts Pipe (which is already integrated into Nest.js) https://github.com/nestjs/nest/blob/master/sample/01-cats-app/src/common/pipes/parse-int.pipe.ts

Hello @jaufgang, That’s why we have param-scoped pipes. Usage example https://github.com/nestjs/nest/blob/master/examples/01-cats-app/src/modules/cats/cats.controller.ts Pipe https://github.com/nestjs/nest/blob/master/examples/01-cats-app/src/modules/common/pipes/parse-int.pipe.ts
