Code Sandbox: https://codesandbox.io/s/jolly-leaf-hfs27

App.js

import { ScrollRestorer } from 'react-scroll-restorer';

const App = () => {
  return <ScrollRestorer>
    child components ...
  </ScrollRestorer>
}

ChildComponent.js

import { useScrollRestorer } from 'react-scroll-restorer';

// ChildComponent with scrollable content
const ChildComponent = () => {
  useScrollRestorer("unique-key");
  // "unique-key" has to be unique for each instance.
  // If you are using multiple instances, then pass
  // a unique key via props from parent component.

  return <div>
    scrollable content ...
  </div>
}

With Dependencies

Each time a dependency is updated, the scroll is restored.

import { useScrollRestorer } from 'react-scroll-restorer';

// ChildComponent with scrollable content
const ChildComponent = () => {
  const [loading, setLoading] = React.useState(false);
  useScrollRestorer("unique-key", [loading]);
  // adding [loading] will restore the scroll
  // everytime loading is updated.
  // You can add more dependencies as well.

  React.useEffect(() => {
    // this would be something like a fetch request
    window.setTimeout(() => {
      setLoading(true);
    }, 500);
  }, []);

  return <div>
    {loading 
      ? "loading ..."
      : "scrollable content ..."}
  </div>
}
