isFetched vs isSuccess
Can anyone explain what the difference is between
isFetched and isSuccess?
I have seen some other developers using these two flags to determine if data is "ready" in our application, and after reading the docs, I am not clear what the impact would be of using one vs the other.2 Replies

isFetched is also true when the query errors

From what I could tell,
isSuccess is more of a guarantee that the data will not be undefined (unless you explicitly return undefined from your query function).
isFetched doesn't do any type narrowing.
