switchMapSuspended()
Like switchMap, but applying a startWith(SUSPENSE) to the inner Observable.
function switchMapSuspended<T, O extends ObservableInput<any>>(project: (value: T, index: number) => O):
OperatorFunction<T, ObservedValueOf<O> | typeof SUSPENSE>;
Arguments
project: A function that, when applied to an item emitted by the source Observable, returns an Observable.
Returns
OperatorFunction<T, ObservedValueOf<O> | typeof SUSPENSE>: An Observable that emits the result
of applying the projection function to each item emitted by the source Observable, and taking only the values from
the most recently projected inner Observable, prepended with SUSPENSE.
Example
import { switchMapSuspended } from '@react-rxjs/utils'
const story$ = selectedStoryId$.pipe(switchMapSuspended(getStory$))
