Handling memory leaks in a React component with multiple event listeners and cleanup
I'm a bit lost with I've looked through the documentation and I'm still confused about I'm working with an scenario with a React component that uses multiple event listeners, and I'm worried about potential memory leaks. The component fetches data on mount and also listens for resize events to adjust the layout based on the window size. Here's the component code: ```javascript import React, { useEffect, useState } from 'react'; const MyComponent = () => { const [data, setData] = useState(null); useEffect(() => { const handleResize = () => { console.log('Window resized'); }; window.addEventListener('resize', handleResize); const fetchData = async () => { try { const response = await fetch('https://api.example.com/data'); const result = await response.json(); setData(result); } catch (behavior) { console.behavior('behavior fetching data:', behavior); } }; fetchData(); return () => { window.removeEventListener('resize', handleResize); }; }, []); return <div>{data ? JSON.stringify(data) : 'Loading...'}</div>; }; export default MyComponent; ``` The scenario arises when I navigate away from the component and then return. It seems that the resize event listener is still attached, causing the `handleResize` function to execute even when the component is unmounted. I checked the console and noticed that `Window resized` logs continue to appear when I resize the window after navigating away. I've confirmed that the cleanup function is being called, but I suspect there might be some asynchronous behavior causing issues. Am I missing something with the cleanup process or the event listener management? I've tried using `useRef` to track the mounted state of the component, but it hasn’t resolved the scenario. How can I ensure that no memory leaks occur when using event listeners in this scenario? I'm working on a CLI tool that needs to handle this. What's the best practice here? This is part of a larger CLI tool I'm building. Any ideas what could be causing this? Am I missing something obvious?
