Skipped Query returns outdated data after cache clearing

[MardanovaA]

I have query to get user data (roles, username)

   const token = getCookie(CookieNames.TOKEN);
   const { data, refetch, loading } = useUserGetCurrentQuery({
     skip: !token,
   });

Also I have storeClearing on logout

export const logout = async () => {
  const apolloClient = initializeApollo();

  removeCookie(CookieNames.TOKEN);
  localStorage.deleteItem('refreshToken');

  logoutEvent();

  await apolloClient.clearStore();
  await redirect({ route: routes.AUTH });
};

After cache clearing on auth page we call getUserData hook. As token is empty I expected, what query will skipped and data would be undefined. But it still returns old data, cache is clear though. It is make bug: when I logout, changing userData on database and login again - then I have outdated data.

Any help please, I blew my mind 🤯

If your hook was mounted all that time, that is possible.

Generally, cache updates are forwarded to the hooks, but skipping a hook also means skipping any updates from the cache - including a cache reset.

If the component with that hook would be unmounted and remounted, it would start with a blank state, but since it seems to stay mounted in your case, the moment you "un-skip", it will pick back up with the last state it had and wait for future cache updates.

@phryneas Thank you very much! I spent 3 days searching for this information.
Is there any possibility using Apollo to update this query so that it returns undefined? Or just remount?

[phryneas]

I think remounting is the safest bet you have - just put a key on a component very far up in your component tree and change that. That also ensures you don't have other stale local component state from the last user session.

Thank you! I'll try this variant

I think I can close this issue then - but please feel free to open a new issue in the future :)
