How do I identify isLoaded?

isLoading is not enough

isLoading => false-> true-> false
isLoaded => false -> true

You can't simulate this yourself, because it's only executed the first time you useHook, and all subsequent useHooks will return the initialization false.

  const [isLoaded, setIsLoaded] = useState(false)
  const { data } = useSWR(
    ['/api', queryParams],
    ([url, queryParams]) =>
      axios(url, {
        params: queryParams,
      }),
    {
      onSuccess: () => {
        setIsLoaded(true) // 
      },
    }
  )

I think I've figured out that the isLoaded state is not needed.

isLoading =>  true-> false
