import { IsDefined, Max, MaxLength, Min, MinLength } from 'class-validator';

class UserDto {
  @MinLength(2)
  @MaxLength(10)
  public readonly nickname: string;

  @Min(1)
  @Max(100)
  public readonly age: number;
}

class CreateUserDto extends UserDto{} // I want nickname and age to be required in this class
class UpdateUserDto extends UserDto{}  // I want nickname and age to be optional in this class

Is there any way to achieve this without repeating the same code three times?

it should work without needing to do anything extra

doesn't it?

since the fields are inherited and the decorators are related to those fields
