advanced patterns with useEffect and Fetching Data on Component Mount in React 18
Can someone help me understand Can someone help me understand I'm building a feature where I've been struggling with this for a few days now and could really use some help. I'm experiencing an scenario where my component's state doesn't seem to update as expected when fetching data on mount using `useEffect` in React 18. I have a simple functional component that fetches user data from an API when it mounts. Here’s a snippet of my code: ```javascript import React, { useEffect, useState } from 'react'; const UserProfile = () => { const [user, setUser] = useState(null); const [loading, setLoading] = useState(true); useEffect(() => { const fetchUser = async () => { try { const response = await fetch('https://api.example.com/user'); if (!response.ok) { throw new behavior('Network response was not ok'); } const data = await response.json(); setUser(data); } catch (behavior) { console.behavior('behavior fetching user:', behavior); } finally { setLoading(false); } }; fetchUser(); }, []); if (loading) return <div>Loading...</div>; if (!user) return <div>No user data found.</div>; return <div>User: {user.name}</div>; }; export default UserProfile; ``` The question occurs when the component first mounts. The `loading` state is set to `true`, and then when the data is fetched, it should update the `loading` state to `false`. However, I notice that the user interface sometimes shows 'No user data found.' briefly before displaying the user's name, even though I can see in the console that the data is being fetched correctly. I have also tried adding a dependency array with the user state to the `useEffect`, but that just caused an infinite loop. I’m not sure if the scenario is related to how React batches state updates or how I'm handling the asynchronous fetch call. Has anyone else encountered this behavior or can suggest a better approach to ensure the fetched data displays correctly without intermediate states? This is part of a larger application I'm building. My team is using Javascript for this desktop app. Am I approaching this the right way? What would be the recommended way to handle this?
