React 18: Issue with Persisting State Across Reloads Using Local Storage and useEffect
Does anyone know how to I'm collaborating on a project where I'm having trouble with I'm stuck trying to I'm working on a personal project and I'm trying to persist a piece of state in my React 18 application using local storage, but I'm encountering unexpected behavior when reloading the page. I've set up a simple counter that should increment and save its value to local storage whenever it changes. However, after a page reload, the counter resets to 0 instead of the last saved value. Here’s a simplified version of my code: ```jsx import React, { useState, useEffect } from 'react'; const Counter = () => { const [count, setCount] = useState(0); useEffect(() => { const storedCount = localStorage.getItem('count'); if (storedCount) { setCount(Number(storedCount)); } }, []); useEffect(() => { localStorage.setItem('count', count); }, [count]); return ( <div> <h1>Count: {count}</h1> <button onClick={() => setCount(count + 1)}>Increment</button> </div> ); }; export default Counter; ``` I expected that when I reload the page, the `useEffect` hook should read the value from local storage and set the count accordingly. However, I see the initial count is always 0. I’ve confirmed that local storage is properly set and contains the expected value, but it seems like the initial effect doesn't run as expected upon page load. I’ve tried adding console logs to verify if the `useEffect` for loading the count is firing correctly, and it does run, but the state never reflects the stored value. My local storage looks like this: ``` { count: "5" } ``` I've also tried removing the `Number` conversion just in case it was causing an issue, but that didn't help either. What am I missing here? Is there something I'm not considering with how state and effects work in functional components with local storage? Any insights would be appreciated! I'm working on a web app that needs to handle this. Any ideas how to fix this? Thanks for taking the time to read this! This is part of a larger web app I'm building. This is happening in both development and production on macOS. I appreciate any insights!
