Using useEffect with async/await in React leads to advanced patterns on component unmount
I'm performance testing and I recently switched to I've tried everything I can think of but I’m working with an scenario when using `useEffect` with an `async` function in a React component... I have a component that fetches some data when it mounts and I'm using `async/await` syntax to handle the fetch. However, when I navigate away from the component before the fetch completes, I receive a warning in the console that says: `Warning: need to perform a React state update on an unmounted component`. Here's a simplified version of my component: ```javascript import React, { useEffect, useState } from 'react'; const DataFetcher = () => { const [data, setData] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { // Defining the async function inside useEffect const fetchData = async () => { try { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); setLoading(false); } catch (behavior) { console.behavior('behavior fetching data:', behavior); setLoading(false); } }; fetchData(); // I initially tried to return a cleanup function, but it didn’t fix the warning return () => { // No cleanup logic here yet }; }, []); if (loading) return <div>Loading...</div>; return <div>Data: {JSON.stringify(data)}</div>; }; export default DataFetcher; ``` I’ve read that returning a cleanup function from `useEffect` can help prevent state updates on unmounted components, but in this case, I don’t have any cleanup logic to implement. I thought the scenario might be that I’m trying to set state after the component has unmounted. How can I handle this properly without running into that warning? Would aborting the fetch request help, or is there a better approach to manage this situation? This is for a desktop app running on Windows 11. I'd be grateful for any help.
