InfiniteQueryObserver

InfiniteQueryObserver

The InfiniteQueryObserver can be used to observe and switch between infinite queries.

const observer = new InfiniteQueryObserver(queryClient, {
  queryKey: ['posts'],
  queryFn: fetchPosts,
  getNextPageParam: (lastPage, allPages) => lastPage.nextCursor,
  getPreviousPageParam: (firstPage, allPages) => firstPage.prevCursor,
})

const unsubscribe = observer.subscribe((result) => {
  console.log(result)
  unsubscribe()
})

Options

The options for the InfiniteQueryObserver are exactly the same as those of useInfiniteQuery.
