jotaiのuseAtom()で更新関数の型がnever

Posted at

状態管理ライブラリjotaiを使ってみて、最初にはまったところのメモ

やりたいこと

useAtom()を使って値を更新

const [loading, setLoading] = useAtom<boolean>(loadingState);

return (
    <Button onClick={() => setLoading(!loading)}>button</Button>
  );

すると型 'never' には呼び出しシグネチャがありません。と言われる

結論

型を書かない

const [loading, setLoading] = useAtom(loadingState);

なんでかな
