What is the proper way to input properties when merging objects for the getInitialState function within a createEntityAdapter object?

How can I use the FetchingStatus type to create a status variable?

type FetchingStatus = 'idle' | 'loading' | 'succeeded' | 'failed';

const initialState = companyPagesAdapter.getInitialState({
        status: 'idle',
        perPage: 1,
        lastPage: 1
    });

The getInitialState function signature is as follows:

getInitialState<S extends object>(state: S): EntityState<T> & S

Answer №1

type RequestStatus = "inactive" | "fetching" | "completed" | "failed";
    
    
interface CustomEntityAdapterState {
    status: RequestStatus,
    itemsPerPage: number,
    totalPages: number
}

const defaultState: CustomEntityAdapterState   = {
  status: 'inactive',
  itemsPerPage: 10,
  totalPages: 5
});

businessAdapter.getInitialState(defaultState)

This approach has proven successful for me. Reducer actions provide the necessary restrictions.
