Why useMutation resets status and isPending when user navigate between routes

[ZeroProger]

Need help with useMutation.
isPending resets to false and status resets to idle when i very fast change page:
from /servers/[serverId]/overview to /servers/[serverId]/players and back to /servers/[serverId]/overview.

In devtools network this request still pending, but status resets to idle and isPending resets to false.

If i stay on/servers/[serverId]/overview page (where i start request) status and isPending works correct.

I use "next": "^13.5.2" with app router.
I use "@tanstack/react-query": "^5.38.0"
I can`t disable request send button, if page changed - button is not disabled, is page not changed - button disabled correctly.

how i use it:

export function useStopServerMutation() {
	const serverHash = useStore($serverHash)
	const queryClient = useQueryClient()

	return useMutation({
		mutationFn: stopServer,
		onSettled: async (response, error) => {
			if (!response) return

			if (response.success) {
				await queryClient.invalidateQueries({ queryKey: [ReactQueryKeys.server] })
				await queryClient.invalidateQueries({
					queryKey: [ReactQueryKeys.serverMainInfo, serverHash],
				})
			}
		},
	})
}

export function StopServer() {
	const serverHash = useStore($serverHash)

	const { isPending, mutateAsync } = useStopServerMutation()

	const handleClick = () => {
		mutateAsync({ gameServerHash: serverHash! })
	}

	return (
		<Button
			className="text-xl flex flex-row items-center flex-nowrap gap-2"
			onClick={handleClick}
			disabled={isPending}
			variant="ghost"
		>
			<Square size={24} className="text-destructive fill-destructive" />
			Остановить
		</Button>
	)
}

Mutations don't share state like Queries do. Whenever you mount a component, it gets a new instance of a Mutation. This makes sure you can trigger the same mutation multiple times.

So if you navigate away and back, useMutation is "fresh" and doesn't know anything about any mutation fired in the past.

You can use useMutationState to read the state of all mutations in the cache.
