RTKQ: use forceRefetch to invalidate query data?

[MaximKondratev]

I have some charts data that I want to invalidate after 180 seconds if query with associated arg called. keepUnusedDataFor does not suit this case as it invalidates data only if it was not used for the time passed. I want to invalidate it no matter if used or not.

I am trying to do this by forceRefetch:

const CHART_TTL_MS = 1000 * 180;

forceRefetch: ({ endpointState }) => {
    if (!endpointState) {
        return true;
    }

    const startedTimeStamp = endpointState.startedTimeStamp;
    const nowTimeStamp = new Date().getTime();

    if (nowTimeStamp - startedTimeStamp > CHART_TTL_MS) {
        return true;
    }

    ...
}

This actually works, it starts refetching, but I see "previous" data rendered for a moment before state isFetching switching to true and I can render some loading view . I could not find any flag or something else to not render that previous data or any way to understand it is going to refetch.

Is there something I missed? Or is it impossible to do invalidation this way?

Do you maybe want to use polling?

[MaximKondratev]

Well actual use case is a little harder but if my suggestion with forceRefetch would work it would not matter.

I have some tabs switching time boundary of a chart. Those chart may or may not include "today" data, so I only want to invalidate those which are "live" and not invalidate those which are in past (since they will not change 100%). If I understand correctly, I can not do this only with pollingInterval since my case depends on data itself.

At forceRefetch level I have all information to invalidate or not to.

For now I already have all this logic written with thunks. I am trying to migrate it to createApi since it will reduce a lot of hand written code like storing pending states and so on. But sadly I can not manipulate invalidation by myself which seems like some basic need.

Anyway thanks for your great job over redux. Pls let me know if my request is impossible for now, that's the answer too.
