What methods are available to prevent redundant types in Typescript?

Consider an enum scenario:

enum AlertAction {
  RESET = "RESET",
  RESEND = "RESEND",
  EXPIRE = "EXPIRE",
}

We aim to generate various actions, illustrated below:

type Action<T> = {
  type: T;
  payload: string;
};

type ActionType =
  | Action<Action.RESET>
  | Action<Action.RESEND>
  | Action<Action.EXPIRE>;

In ActionType, the code Action<enum> is repeated several times.

Is there a way to avoid redundantly writing Action<enum>?

Answer №1

It's simple:

define ActionType as Action<AlertAction>
