useFirestoreInfiniteQuery with realtime subscriptions supported?

[davidoort]

Hey, I'm just wondering if this is supported or if there's a workaround to make this work with this library?

The goal is to have an infinite scroll list where the items update in realtime.

This package has useInfiniteQuery hook.
Here is an example of how to use it:

const getInitialPageParam = () => {
        return by === "createdOn"
            ? direction === "desc"
                ? Infinity
                : -Infinity
            : direction === "desc"
              ? "~"
              : "";
    };

    const getNextPageParam = (lastPage) => {
        return (lastPage?.length ?? 0) > 0 ? lastPage[lastPage.length - 1].createdOn : "";
    };

    const getPrevPageParam = (firstPage) => {
        return (firstPage?.length ?? 0) > 0 ? firstPage[0].createdOn : "";
    };

   const collectionReference = useCollectionReference({ path: COLLECTION_PATH }).withConverter(converter);

    useInfiniteQuery({
        options: {
            queryKey: ['mykey'],
            initialPageParam: startAfter(getInitialPageParam()),
            getNextPageParam: (lastPage) => {
                return startAfter(getNextPageParam(lastPage));
            },
            getPreviousPageParam: (firstPage) => {
                return endBefore(getPrevPageParam(firstPage));
            },
        },
        query: collectionReference,
        queryConstraints: [orderBy(by, direction)]
    });
