Error for useStore: Warning: The result of getSnapshot should be cached to avoid an infinite loop

[adamtaylor13]

I'm using nanostores (0.9.3), in astro (1.9.0) with react (18.0.0).

I've got this store:

import { DataResponse } from "@components/hooks/useApi";
import { createFetcherStore } from "@stores/apiFetcher";
import { useStore } from "@nanostores/react";

export const $account = createFetcherStore<DataResponse<"/account">>([
    "/account",
]);

export const useAccount = () => {
    const fetchResults = useStore($account);
    
    // ...

    return fetchResults;
};

Used in a React component like so:

export default function NavAuthOptions() {
    const { data: account } = useAccount();
    // ...
}

And I get this error in the console:

I should note however that there doesn't actually appear to be any errors. The site seems to function just fine, which may actually be more disconcerting than the error itself!

My Google-Fu has failed me here as the only semi-related issue I could find was this pmndrs/zustand#1936, however it doesn't appear related as I don't have a .getState() function.

I've also tried just using useStore($account) directly inside my component instead of importing useAccount, but the error still shows in the console.

Also getting this error using nanostore query/react with react + astro

Any luck resolving it?

My code for reference: https://github.com/BTS-CM/astro-ui/blob/main/src/components/common/DeepLinkDialog.jsx

@grctest Unfortunately no—we've just shipped it with the error, which hasn't seemed to affect our site at all. But like I said above, that's more disconcerting than the error itself. Why would we be logging errors if there isn't actually an error? So far no one from nanostores has reached out to assist with this :/

It seems like it's a known React issue? facebook/react#24508 (comment)

Is there any updates on this issue. I have the same with nanostores/query and nanostores/react.

I am not using React anymore, so someone else needs to do research and find a solution.

I found this solution...

const $polls = createFetcherStore<Polls>(["/demo/polls.json"]);
const data = useStore($polls, {}, "data");
console.log(data);

but useStore() does call render second time :-/ maybe React feature

opts.keys param causes much more changes... listenKeys() has some bug... data key is key of createFetcherStore

let store = useStore($polls, {keys: ["data"]});
console.log(store);

[JosefJezek]

@ai could you fix this issue?

[ai]

@JosefJezek can use send PR? I can’t copy code from screenshots.

[JosefJezek]

my change in useStore...

const getKey = () => {
  const store = get();
  return storeKey ? store[storeKey] : store;
};

return useSyncExternalStore(subscribe, getKey, getKey);

[ai]

@JosefJezek we don’t have storeKey in the useStore. Please, send PR, it will be faster.

[JosefJezek]

my solution is not perfect... we need const { data, loading, error } = useStore($post);, not only one key data

please fix createFetcherStore, this store has too many changes
