React Component Not Re-Renders After State Update with useEffect Dependencies
I've been struggling with this for a few days now and could really use some help. I've searched everywhere and can't find a clear answer. I'm having trouble with a React component not re-rendering as expected after updating state using the `useEffect` hook. I have a functional component that fetches data from an API and updates the local state. The problem arises when I try to update the state based on the API response. Specifically, I expect the component to automatically re-render when the state updates, but it doesn't. Here's the relevant code snippet: ```javascript import React, { useState, useEffect } from 'react'; const DataFetcher = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { const fetchData = async () => { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); setLoading(false); }; fetchData(); }, []); // empty dependency array // This is where I expect re-rendering if (loading) return <div>Loading...</div>; return <div>{data ? JSON.stringify(data) : 'No data available'}</div>; }; export default DataFetcher; ``` In this code, I'm fetching data from an API when the component mounts and updating the `data` state. However, after the state update, the component doesn't re-render as I expect. I've also tried adding `data` to the dependency array, which led to an infinite re-render loop, and removing it entirely causes no updates at all. The console shows no errors, but I’ve noticed that the `fetchData` function is correctly called, and the `data` state gets updated. I’m using React 17.0.2, and I have checked that there’s no memoization preventing the re-render. Any suggestions on how to resolve this issue? Am I missing something in the way `useEffect` handles state updates? For context: I'm using Javascript on Windows. Am I missing something obvious? I'm open to any suggestions. This is happening in both development and production on CentOS. Any advice would be much appreciated.
