How to invalidate query in T3?

Hello, how can i invalidate query in TRPC like that?

const user = await api.user.getMe.query();

const user = await api.user.getMe.query();

When its query, but it does not have any queryKey, revalidate or something like that.. Im using T3 Stack with nextjs. Thanks!

you cant invalidate query because its not being cached anywhere

heres how invalidation works in general https://trpc.io/docs/client/react/useUtils#query-invalidation

useUtils | tRPC

useUtils is a hook that gives you access to helpers that let you manage the cached data of the queries you execute via @trpc/react-query. These helpers are actually thin wrappers around @tanstack/react-query's queryClient methods. If you want more in-depth information about options and usage patterns for useUtils helpers than what we provide her...

I mean useQuery, wrong snippet, sorry:

const user = api.user.getMe.useQuery();

const user = api.user.getMe.useQuery();

i can use refetch on that but i cannot pass any keys or something to useQuery?

i've send snippet before i started reading. Now i saw that, thanks! cowbiggy

as i can see i cannot force server TRPC request to refetch? Or ill just need to revalidate the route with nextjs?
