Developing a custom hook for managing data list state can lead to unexpected behavior due to closure-related issues. The hook maintains internal state and exposes methods for external interaction.

function useDataList() {
  const [dataItems, setDataItems] = useState([])
  const [currentPage, setCurrentPage] = useState(0)
  
  async function fetchNextPage() {
    const response = await api.fetchPageData(currentPage + 1)
    setDataItems(response.data.items)
    setCurrentPage(currentPage + 1)
  }
  
  return {
    dataItems,
    setCurrentPage,
    fetchNextPage
  }
}

When implementing this hook within a component, initialization requires careful handling:

function DataTable() {
  const {dataItems, setCurrentPage, fetchNextPage} = useDataList()
  
  useEffect(() => {
    setCurrentPage(-1) // Setting to -1 so fetchNextPage requests page 0
    // Delay execution since state updates are asynchronous
    Promise.resolve().then(fetchNextPage)
  }, [])

  return (
    // Render dataItems in UI
  )
}

The issue manifests when api.fetchPageData() requests page 1 instead of page 0. This occurs because fetchNextPage captures the initial currentPage value (0) during the first render, creating a stale closure.

Since useEffect executes only once, the referenced fetchNextPage function retains the original currentPage value from the initial hook invocation.

To address this, the useMemoizedFn utility from ahooks library provides a solution by ensuring functions always access current state values:

function DataTable() {
  const {dataItems, setCurrentPage, fetchNextPage} = useDataList()
  const stableFetchNextPage = useMemoizedFn(fetchNextPage)
  
  useEffect(() => {
    setCurrentPage(-1)
    Promise.resolve().then(stableFetchNextPage)
  }, [])
  
  return (
    // Render dataItems in UI
  )
}

This approach ensures the wrapped function maintains reference stability while accessing updated state values.
