Validation

TIP

This feature is inspired by NestJS controllers

DTO Validation is implemented by the @Body decorator, the decorator will handle validations set by class-validator package.

typescript

import { IsString, IsInt } from 'class-validator';

export class CreateCatDto {
  @IsString()
  name: string;
  
  @IsInt()
  age: number;

  @IsString()
  breed: string;
}
