When using the *ngrxLet structural directive in an app, the view is cleared as soon as ngOnDestroy() is called. This causes an issue with animations: the view that is animated out changes as all ngrxLet templates get cleared.

To illustrate the problem see this StackBlitz, compare the ngIf behavior with ngrxLet: https://stackblitz.com/edit/ngrx-bug-ngrxlet

I believe the problem could be fixed

When I use removeItem state operator then TypeScript complains that message object can be possibly undefined even though I specified the type for removeItem operator. I could fix the issue with optional chaining but that is not possible if I want to use a utility library like Ramda

Are you open to adding a Payload utility type? I think the following would be fairly useful:

const action = createActionCreator(
	'FOO',
	resolve => (foo: string) => resolve({ foo }),
)

// Get the payload type of this action
const FooPayload = Payload<typeof action>

Essentially I think you can do something like this but it would be better to make it generic.
