Ways to eliminate the 'all' term from a generic restriction

I am encountering some difficulties in developing a generic function without using the any keyword, as it is not recommended by our linter. I attempted to replace it with unknown or never since I do not necessarily need to identify the specific type. However, this approach only resulted in different errors.

While I could simply stick with any and disable our linter for that particular case, I am eager to explore if there is an alternative solution available.

Below is a simplified and modified version of the code for illustrative purposes (TS Playground):

interface DialogContent<TResult> {
  close: Subject<TResult>;
}

function showDialog<T extends DialogContent<<any /*what can be used here instead of any */>>(resolver: () => T)
{
  //...
}


class ExampleDialogContent implements DialogContent<void>{
  close = new Subject<void>();
}

showDialog<ExampleDialogContent>(() => new ExampleDialogContent());

Answer №1

Opting for the any type is the ideal choice in this scenario as it is versatile enough to encompass any form of the generic DialogContent type. Suppressing the lint using a comment would be the most effective solution.
