How to set a default value as an observable

[ianjamieson]

I have ngrx-forms set up as per the documentation and can of course set an initial value like this:

export const initialState: FormGroupState<TermsFormState> = createFormGroupState<TermsFormState>(FORM_ID, {
  terms: 'Initial value'
});

However, the initial value is currently an observable, what is the best way to assign this value as the initial value? I was thinking using soemthing like this:

    this.formState$ = this.store.pipe(
      select(fromForms.getTermsForm),
      withLatestFrom(fromDefaults.getDefaults),
      map(([formState, defaults]) => {
        if (formState.isUntouched) {
          formState.controls.terms.setValue(defaults.terms);
        }
        return formState;
      })
    );

But it seems a little clunky just to set default values and also isUntouched always returns true

Implemented a variation of the methods above, setting default state with a new action
