Possible to access data in autoRefetch()? (@pinia/colada-plugin-auto-refetch)

[OwenVey]

I really would like to be able to do something like:

const { data } = useQuery({
  key: () => ['key'],
  staleTime: 1000 * 10,
  query: fetchData,
  autoRefetch: (data) => data.status === 'PENDING',
})

where I can enable/disable autoRefetch based on the latest data. Currently, when trying to reference data coming back from useQuery, I get a ReferenceError: Cannot access 'benefits' before initialization error.

It would be nice to have something like TanStack Query's refetchInterval

It's possible to add it at https://github.com/posva/pinia-colada/blob/main/plugins/auto-refetch/src/index.ts#L71 by changing the autoRefetch option to also accept a function

In what cases does the data change the setting?

[OwenVey]

In my case, I'm essentially doing polling by setting the staleTime low and using the auto refetch plugin. However, I only want to poll when one of the objects in my data array has a status of "PENDING".

Different use case that shows TanStack Query's implementation's power:

const { data, refetch, isFetching } = useQuery({
  queryKey: ['flightStatus', flightId],
  queryFn: () => fetchFlightStatus(flightId),
  refetchInterval: (query) => {
    const status = query.state.data?.status

    switch (status) {
      case 'scheduled':
        return 5 * 60 * 1000 // 5 minutes
      case 'boarding':
        return 60 * 1000 // 1 minute
      case 'in_air':
        return 30 * 1000 // 30 seconds
      case 'landed':
      case 'cancelled':
        return false // stop polling
      default:
        return false
    }
  },
})

I actually like the idea of having the ability to dynamically change the interval rate but I know that's more of a change than just enabling or disabling autoRefetch

I think it's worth adding this change! We can keep the true behavior to use staleTime and a number for a custom value. Replace MaybeRefOrGetter with the value or a a getter that gets the state (data, error). It shouldn't be too hard to add if you want to open a PR!
