onSuccess for useQuery

[itsmahmoud-dev]

Can we have an onSuccess function for useQuery like the one for useMutation. What I'm thinking of is a function that runs when the query finishes successfully, one solution is to a useEffect with isSuccess condition to run the function. But what if I want to invalidate this query from another page and have its onSuccess function run automatically when the refetching finishes.

We've had this in the past and it was bad. Have a read here on why we removed it: https://tkdodo.eu/blog/breaking-react-querys-api-on-purpose

Yeah I see now why it's deprecated. Guess I'll have to stick with useEffect
