React Router useLocation hook returning stale state in nested routes

react react-router useLocation javascript

I'm learning this framework and I'm sure I'm missing something obvious here, but I'm encountering an issue with the `useLocation` hook from React Router (v6.3.0) in my application. I have a parent route that renders a child component, and I need to access the location state from the parent inside the child component. However, when navigating back and forth between routes, the `location.state` in my child component seems to return stale values. Here's a simplified version of my code: ```javascript // App.js import { BrowserRouter as Router, Routes, Route } from 'react-router-dom'; import Parent from './Parent'; function App() { return ( <Router> <Routes> <Route path="/parent" element={<Parent />} /> </Routes> </Router> ); } export default App; // Parent.js import { Link, Outlet, useLocation } from 'react-router-dom'; function Parent() { const location = useLocation(); return ( <div> <h1>Parent Component</h1> <Link to="/child" state={{ fromParent: 'Hello from Parent!' }}>Go to Child</Link> <Outlet /> </div> ); } export default Parent; // Child.js import { useLocation } from 'react-router-dom'; function Child() { const location = useLocation(); console.log(location.state); // Stale or undefined on back navigation return <h2>Child Component</h2>; } export default Child; ``` When I navigate to the Child component, I see the `state` correctly in the console the first time, but if I go back to the Parent and then to the Child again, the `location.state` appears to be stale or even `undefined`. I expected the state to persist across navigation. I've tried using `replace` in the `Link` component, but it doesn't help. Additionally, I've checked that I'm not accidentally remounting components. I also confirmed that the `state` is present in the `Link` upon initial navigation. How can I ensure that the state is updated correctly and persists when navigating back and forth? Any help would be appreciated! Is there a better approach? Any help would be greatly appreciated! What's the correct way to implement this?
