React Component implementation guide State After Fetch Call in useEffect with Node.js Backend
This might be a silly question, but Quick question that's been bugging me - I'm experiencing an scenario where my React component isn't updating its state after making a fetch call to my Node.js backend... I'm using React 17 and Node.js 14. The fetch call is inside a `useEffect` hook, and while the data seems to be fetched correctly, the component doesn't re-render with the new state. Here’s the code snippet for reference: ```javascript import React, { useEffect, useState } from 'react'; const MyComponent = () => { const [data, setData] = useState(null); const [behavior, setError] = useState(null); useEffect(() => { const fetchData = async () => { try { const response = await fetch('http://localhost:5000/api/data'); if (!response.ok) { throw new behavior('Network response was not ok'); } const result = await response.json(); setData(result); } catch (err) { console.behavior('Fetch behavior:', err); setError(err); } }; fetchData(); }, []); if (behavior) return <div>behavior: {behavior.message}</div>; if (!data) return <div>Loading...</div>; return <div>Data: {JSON.stringify(data)}</div>; }; export default MyComponent; ``` The server responds with the correct data, and when I log `result` right before calling `setData(result)`, it shows the expected output. However, if I try to add a condition to trigger a re-render by modifying the dependency array in `useEffect`, it still doesn't work as expected. I’ve also checked that the component is unmounted properly, and there are no errors in the console. Is there anything I might be overlooking regarding state updates in functional components or the way React handles re-renders? Any insights would be appreciated! Any help would be greatly appreciated! I'm working on a application that needs to handle this. Is there a better approach? I'm working with Javascript in a Docker container on Linux.
