JS проверка вложенных объектов

// If your object contains nested objects and you want
// the validator to perform their validation too, 
// then you need to use the @ValidateNested() decorator:

import { ValidateNested } from 'class-validator';

export class Post {
  @ValidateNested()
  user: User;
}
