Observe All Queries

[RickEyre]

Is there currently a way to observe all queries with one observer?

I think you can manually create a QueryObserver: https://react-query.tanstack.com/reference/QueryObserver

[TkDodo]

not sure, have you tried not passing a queryKey at all?

I just took a look how the devtools do it, because they also observe all queries: They take the queryCache from queryClient and subscribe to the whole queryCache: https://github.com/tannerlinsley/react-query/blob/e3f0ad58e8f63d1c83c0fe18d4711c8c7f52b7c2/src/devtools/devtools.tsx#L392-L396

just saw this:

queryCache.subscribe(() => {
  queryCache.getAll().forEach(query => {
  })
})

This is how the persist plugin works and how I would recommend people listen to the cache.

Thanks @TkDodo, @tannerlinsley. I think I should be able to accomplish what I need with this. I'll post back if I encounter anymore difficulty 👍.

@RickEyre did this end up working pretty well ? If so there any implementations you could share in the wild ?

Or did it end up being pretty noisy? I'm thinking of doing this to post logs onto the cloud for searching and analytics.
