Support for useInfiniteQueries?

[Brodzko]

Hello!

I'm curious whether support for useInfiniteQueries - similar to already existing useQueries is planned? My use-case is a nested list of items, where each level is paginated by the API and should be lazy loaded on scroll.

If there already is a canonical way to go about this I'm happy to learn :)

Many thanks!

I can't say it's on the list, no. But when I look at usInfiniteQuery - it's basically the same as useQuery, as they both useBaseQuery under the hood, just with a different observer - InfiniteQueryObserver. So maybe the QueriesObserver is extensible in the same way 🤔 . Do you maybe want to take a look and tackle it?

I just took a stab at this in a private repo and from what I can see this should work out:

• Ensure InfiniteQueryObserver.setOptions allows to pass notifyOptions to its super class/method
• Make the QueriesObserver class generic to make it work with a list of QueryObserver or a list of InfiniteQueryObserver (maybe introduce an AbstractQueriesObserver that gets the QueryObserver or InfiniteQueryObserver class as a constructor argument and subclass it to QueriesObserver and InfinitQueriesObserver)
• Extract useQueries into useQueriesBase and use it in useQuery and useInfiniteQueries

Not sure if I find time to contribute this upstream as project deadlines are near. Happy if anyone wants to follow this approach before I get to contribute this.
