Unexpected state reset in a functional component after navigating between routes in a Next.js app

react next.js hooks javascript

I've hit a wall trying to Quick question that's been bugging me - I'm experiencing an issue where the state in my functional component resets every time I navigate between routes in my Next.js application..... I'm using React hooks, and the component that holds the state is not unmounted during the navigation, so I expected the state to persist. I have the following code: ```javascript import { useState } from 'react'; import { useRouter } from 'next/router'; const MyComponent = () => { const [count, setCount] = useState(0); const router = useRouter(); const increment = () => { setCount((prevCount) => prevCount + 1); }; return ( <div> <h1>Count: {count}</h1> <button onClick={increment}>Increment</button> <button onClick={() => router.push('/anotherPage')}>Go to Another Page</button> </div> ); }; export default MyComponent; ``` The component works fine on initial load, but when I navigate away and then return, the `count` state is reset to 0. I have ensured that I am not using `key` props that could cause remounting and that the state management is encapsulated within the component itself. Here are a few things I've tried: 1. I verified that the component is not being unmounted by checking the React DevTools. 2. I attempted to use `sessionStorage` to save and retrieve the count value, but that felt like a workaround rather than a proper solution. 3. I ensured that my Next.js version is 13.0.0, and I have updated all dependencies, including React 18. I also checked for any warnings in the console, but there are none. Is there something I'm missing in how Next.js handles state persistence during navigation? Any insights on how to keep the state intact would be greatly appreciated! This is part of a larger API I'm building. Is there a better approach? The stack includes Javascript and several other technologies. Thanks, I really appreciate it! I'd really appreciate any guidance on this.
