React useEffect implementation guide state with fetched data due to stale closure in functional component
I'm maintaining legacy code that I'm working with an scenario in my React component where I'm trying to fetch data using `useEffect`, but the state doesn't update correctly due to what I believe is a stale closure question..... I'm using React 17.0.2 and working with functional components. Here's what I've implemented: ```javascript import React, { useEffect, useState } from 'react'; const DataFetcher = () => { const [data, setData] = useState([]); useEffect(() => { const fetchData = async () => { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); }; fetchData(); }, []); return ( <div> <h1>Fetched Data</h1> <ul> {data.map(item => <li key={item.id}>{item.name}</li>)} </ul> </div> ); }; export default DataFetcher; ``` The question arises when I try to call `setData(result)` after fetching the data. The console shows the correct response from the API, but the UI does not update with the new data. Additionally, if I log `data` right after `setData(result)`, it still holds the old value. I've tried adding the `data` state to the dependency array in `useEffect`, but it causes an infinite loop since `setData` triggers a re-render. I also checked that no other part of the component is causing a state override. What am I missing here? I want to ensure that the fetched data updates the state correctly and reflects on the UI without running into stale closures. Any insights would be appreciated. I'd really appreciate any guidance on this. For reference, this is a production microservice. Any ideas what could be causing this?
