I'm a huge fan of this pattern (and as a greybeard). I honestly wonder if people think about such things this day and age where everything is react.

It's amazing how often highly-polished web infrastructure gets put into the trash in pursuit of narrow objectives like avoiding a full page load. Very few applications actually benefit from being a single page. You tend to lose a lot more than you gain in terms of UX.

There are frameworks that navigate like this. Laravel is the first that comes to mind. I think Django and Spring do this as well.

TIL that this (or rather, the lack of this) is why some pages show that annoying "do you want to resubmit your post" notification, but not others, and the name for it. Thank you!
