Need help to understand UseInfiniteHits showPrevious behaviour

[weiklr]

Hi,

I'm not sure if this is a bug, or just lack of understanding on my part, so I posting as a question here with a codesandbox demo.

I'm trying to build my own infinite scroll component with useInfiniteHits hook. While showMore works as intended (page number increases from 1 to 2 to 3, .. etc) i noticed that showPrevious always starts from -1 and not from the 'currentPage' that i was on .

I wish to use showPrevious like this: if i press showMore 2 times, page number becomes from 1 to 3, and i press showPrevious. I would expect showPrevious submit a request to algolia with page number. = 2 but instead it's -1.

So, hopefully someone can guide me on how I can use showPrevious with this scenario.

you can refer to this codesandbox for details:

The goal of showPrevious is to show the "most previous page that isn't already shown". So if you're using showPrevious, it would be more a situation like this:

  3
showMore
  3 4
showPrevious
2 3 4

The showPrevious method and button shouldn't be called when isFirstPage is true

Hi Haroenv,

Thanks for your reply! i should probably think about providing a reload option when i reach the last page or at the first page
