Bi-directional Paginated Queries
The
In some cases you may want to load a paginated list starting from a specific item in the list instead of the start of the list. This is useful for jumping to a particular item in a long paginated list.

Requested Functionality: A hook similar to useInfiniteQuery that functions like convex/react's
I'm still evaluating the docs here to see if this functionality could fit into the existing pagination model used by convex, but I figured I'd post this here to see if anyone has solved this problem previously or if any alternate solutions might exist for jumping to a specific item in a paginated query.
usePaginatedQueryusePaginatedQuery hook currently functions by first loading an initial page of results starting at the top of the list.

This pagination is always one-directional (ie. you always start with the first page and load future pages)In some cases you may want to load a paginated list starting from a specific item in the list instead of the start of the list.

From there the user can call fetchPreviousPage()fetchPreviousPage() to fetch earlier items in the list (ie before the start cursor) and fetchNextPage()fetchNextPage() to fetch later items in the list.Requested Functionality: A hook similar to useInfiniteQuery that functions like convex/react's

Paginating over large datasets is tricky when the data is changing. Naive approaches result in missing or duplicated data. The trick is to rewrite lim...
