Converting an Observable containing an Array of StaffInterface objects to a plain Array of StaffInterface objects in @ngrx/store select

Trying to retrieve an Array<StaffInterface> from an 

Observable<Array<StaffInterface>>
in ngrx store.select. The store.select method returns the 
Observable<Array<StaffInterface>>
, which I then need to convert into an Array<StaffInterface> so that I can pass it to primeng datatable.

staffList: Array<StaffInterface>; 
this.staffList = store.select(staffList);

In the code snippet above, the store.select method is returning an 

Observable<Array<StaffInterface>>
. My goal is to transform this into an Array<StaffInterface>.

Answer №2

Ensure you are subscribing to the value before returning the array in the following manner

this.employees = store.select(employeeList)
                          .subscribe(employeeList => employeeList);

Answer №3

After some consideration, I made adjustments to my code by utilizing store.select in order to fetch the Store's Observable data and storing it as staffList$: Observable. Following the advice of @Brendan, I incorporated the use of the async pipe within the template.

This modification eliminated the need for any type conversions.

staffList$: Array<StaffInterface>;
this.staffList$ = store.select(staffList);

Within the HTML template:

{{staffList$ | async}}
