React Router v6: Nested Routes Not Preserving Parent State
I'm maintaining legacy code that Hey everyone, I'm running into an issue that's driving me crazy. I'm using React Router v6 in my application, and I'm working with an scenario where nested routes do not seem to preserve the parent component's state. I have a parent component that manages an array of items and renders a list of them, each one linked to a nested route. However, whenever I navigate to a nested route, the parent component's state seems to reset, causing the list of items to disappear. Here's a simplified version of my code: ```javascript import React, { useState } from 'react'; import { BrowserRouter as Router, Route, Routes, Link } from 'react-router-dom'; const ParentComponent = () => { const [items, setItems] = useState(['Item 1', 'Item 2', 'Item 3']); return ( <div> <h1>Item List</h1> <ul> {items.map((item, index) => ( <li key={index}> <Link to={`/item/${index}`}>{item}</Link> </li> ))} </ul> <Routes> <Route path="/item/:id" element={<NestedComponent />} /> </Routes> </div> ); }; const NestedComponent = () => { return <div>Details of the selected item</div>; }; const App = () => ( <Router> <ParentComponent /> </Router> ); export default App; ``` On navigating to a nested route (e.g., clicking on 'Item 1'), I expect to see the details without losing the list of items. Instead, I see the list disappear, and the state seems to reset. I've checked the console for errors, but there's nothing alarming. I’ve also tried using `useEffect` to log the `items` state during renders, but it just confirms that the state resets upon navigation. Is there something I'm missing with how React Router v6 manages state? Should I be lifting the state higher or using a context provider instead? Any guidance would be greatly appreciated! Thanks in advance! For context: I'm using Javascript on CentOS. Thanks, I really appreciate it! I'm working with Javascript in a Docker container on Ubuntu 20.04.
