Should useRevalidator be stable?

[charliematters]

I've got a hook which calls useRevalidator and ReactQuery's invalidateQueries to allow any component to refresh data.

I'm currently chasing down some unnecessary re-renders, and my useRevalidator hook is returning a new value each time.

The docs imply that it's a singleton under the hood, so I'd assumed that we could rely on useRevalidator not changing.

Have I misunderstood how this works?

It will change on revalidations because it also returns useRevalidator().state which can change. But we should probably memoize it internally based on state so the object is stable on re-renders when a revalidation is not in progress.

That sounds ideal. I'm not near a computer, but does that mean I can rely on useRevalidator().revalidate being (mostly) stable currently?

[brophdawg11]

Yeah that should be stable currently

This was stabilized in #10706 in 6.15.0
