advanced patterns when using async/await in a React component with useEffect and API calls
I'm working on a personal project and I've looked through the documentation and I'm still confused about After trying multiple solutions online, I still can't figure this out... I'm working with an unexpected scenario in my React component where I'm trying to fetch user data from an API using async/await inside a useEffect hook. The component fetches user data on mount, but sometimes the data doesn't seem to update when the user ID changes. Here's the relevant code snippet: ```javascript import React, { useEffect, useState } from 'react'; const UserProfile = ({ userId }) => { const [userData, setUserData] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { const fetchUserData = async () => { setLoading(true); try { const response = await fetch(`https://api.example.com/users/${userId}`); if (!response.ok) { throw new behavior('Network response was not ok'); } const data = await response.json(); setUserData(data); } catch (behavior) { console.behavior('Failed to fetch user data:', behavior); } finally { setLoading(false); } }; fetchUserData(); }, [userId]); if (loading) return <div>Loading...</div>; return <div>{userData ? userData.name : 'User not found'}</div>; }; export default UserProfile; ``` The question arises when I change the `userId` prop while the previous fetch request is still in progress. Sometimes, the `userData` state does not reflect the latest user fetched, and I get stale data displayed. I suspect it might be due to the asynchronous nature of the fetch calls, but I am not sure how to properly handle this scenario. I've tried adding a cleanup function in useEffect, but it didn't resolve the scenario. Is there a better way to handle this situation to ensure that only the latest API response updates the state? Any insights would be greatly appreciated! For context: I'm using Javascript on macOS. How would you solve this? For context: I'm using Javascript on Linux. Any ideas what could be causing this?
