This is a custom React hook that facilitates scroll restoration for a specific element. It allows you to save and restore the scroll position of an element, optionally persisting it to localStorage or sessionStorage. This can be useful in scenarios where you want to maintain scroll positions across navigation or page refreshes.
It differs from ScrollRestoration in that it can be attached to a specific dom element.

npm install use-scroll-restoration

Here's how you can use the useScrollRestoration hook in your React components:

import React from 'react';
import { useScrollRestoration } from 'use-scroll-restoration';

function ScrollRestorationExample() {
  const { ref, setScroll } = useScrollRestoration('exampleKey', {
    debounceTime: 200,
    persist: 'localStorage',
  });

  return (
    <div ref={ref} style={{ height: '500px', overflow: 'auto' }}>
      {/* Your scrollable content */}
    </div>
  );
}

• key (required): A unique key to identify the scroll restoration context.
• options (optional): An object containing additional options:
  • debounceTime (default: 100): The debounce time (in milliseconds) before saving scroll position.
  • persist (default: false): Specifies where to persist scroll position. Can be false, 'localStorage', or 'sessionStorage'.

Returns an object with the following properties:

• ref: A callback that sets the DOM element reference. Attach this to the ref prop of the scrollable element you want to manage.
• setScroll({ x, y }): A function to manually set the scroll position, where x and y are optional scroll coordinates.
