typescript how to omit enum values

I got enum

enum Status {
  Cancelled = 'cancelled',
  Completed = 'completed',
  Created = 'created'
}

and I want to create another enum only with Completed and Created value

enum StatusMinimal {
  Completed = 'completed',
  Created = 'created'
}

I tried to use Omit but it works only with types. Is it even possible to do it in typescript?

This is similar to this question. You can basically use the builtin TypeScript utility type Exclude.

Or you could do it like this :

enum StatusMinimal {
  Completed = 'completed',
  Created = 'created'
}

enum StatusExtended {
  Completed = 'completed',
  Created = 'created'
}

type Status = StatusMinimal | StatusExtended;

You can define a property/parameter based on the Status and Exclude the unwanted values

function test(s: Exclude<Status, Status.Cancelled>): void {}


test(Status.Completed)
test(Status.Created)
test(Status.Cancelled) // not assignable

As far as I know there is no trivial way. See this similiar question.

I would start with Minimal and extend the Status enum from the minimal implementation. (I know, not what your asked for)
