Issues with state persistence in React when using useReducer with localStorage
I'm converting an old project and I'm stuck on something that should probably be simple. I keep running into I'm confused about I'm relatively new to this, so bear with me... I'm experiencing unexpected behavior when trying to persist state with `useReducer` in my React application. I have implemented a simple counter that should save its value in `localStorage` and retrieve it on subsequent renders. However, after refreshing the page, the state does not persist as expected. Here’s the relevant code snippet: ```javascript import React, { useReducer, useEffect } from 'react'; const initialState = { count: 0 }; const reducer = (state, action) => { switch (action.type) { case 'increment': return { count: state.count + 1 }; case 'decrement': return { count: state.count - 1 }; case 'reset': return initialState; default: throw new Error(); } }; const Counter = () => { const [state, dispatch] = useReducer(reducer, initialState); useEffect(() => { const savedCount = localStorage.getItem('count'); if (savedCount !== null) { dispatch({ type: 'increment', payload: Number(savedCount) }); } }, []); useEffect(() => { localStorage.setItem('count', state.count); }, [state.count]); return ( <div> <p>Count: {state.count}</p> <button onClick={() => dispatch({ type: 'increment' })}>Increment</button> <button onClick={() => dispatch({ type: 'decrement' })}>Decrement</button> <button onClick={() => dispatch({ type: 'reset' })}>Reset</button> </div> ); }; export default Counter; ``` When the component mounts, I check `localStorage` for a saved count and attempt to update the state based on that value. However, every time I refresh the page, the state resets to 0 instead of the saved count. I have verified that the value is correctly stored in `localStorage` by checking the browser's dev tools, so it seems like the issue lies with how I am dispatching the initial state update. I have also tried changing `dispatch({ type: 'increment', payload: Number(savedCount) });` to `dispatch({ type: 'set', payload: Number(savedCount) });` and modifying the reducer to handle a 'set' action but that didn't resolve the issue either. What am I missing here? How can I properly retrieve and set the initial state from `localStorage` using `useReducer`? I'm working on a application that needs to handle this. What am I doing wrong? I'm using Javascript 3.11 in this project. Am I missing something obvious? My team is using Javascript for this desktop app. I'm working in a CentOS environment. Has anyone else encountered this? My team is using Javascript for this desktop app. Could this be a known issue?
