I'm a self taught PHP/jQuery/bootstrap guy with a small saas. I handle page scroll position by literally saving it into some session data cookie and when you go back I check where your scroll was and I fix it for you. I'm not a genius or skilled... But I cared so I did it.

I write some of my thoughts on this sone years ago. The library described at the end is now fairly out of date but the ideas and suggestions are still good, I think.

Depends on what you're using for routing.

In Tanstack Router it's a boolean you set when creating the router. The documentation nicely lays out what's being done under the hood, and it's quite a bit.[1] I wouldn't try that at home.

In React Router you just chuck a <ScrollRestoration /> somewhere in your DOM.[2]
