`data` becomes undefined / stale data for a second
I am using react-query like so. I am noticing that when I change the value of
page via client state, the data returned by the useQuery reverts back to initialData while the fetch happens and then gets populated with the new data. It results in incorrect data being shown for the duration of the fetch (half a second).
How can I prevent this?

by not setting
initialData for a query if you don't want it.
Every new queryKey creates a new query (you can see that in the devtools), and every time a new query is created, initialData will be respected.
so you need to conditionally set initialData if you only want it for a specific seenPagerival-blackOP•15mo ago
makes sense. But why does
data become undefined for a second when the query key changes? (considering I do not provide initialData). Is there any way to change this behaviour?conscious-sapphire•15mo ago
a new key means a new query, which is in
status: 'pending', data: undefined. It doesn' t know anything about other queries. You can set placeholderData: (previousData) => previousData to keep data of previous queries on screen while you are transitioning between queriesrival-blackOP•15mo ago
okay thanks. thats what I needed. Is this not the default behaviour?
