Could you write some tests for this?

[NoNameProvided]

Closing this as wontfix because we won't add a second port decorator. We already have a @IsPort decorator. The discussion of how to handle string vs number should be discussed there and a solution implemented in the original one.

In the meantime, if you strictly want to accept numbers you can use the following:

class MyPayload {
  @IsNumber()
  @Min(0)
  @Max(65535)
  port: number;
}
