Navigation guard hooks (confirm leaving page)

[mablin7]

Description

I am not sure if there is a good way to do this currently with client side routing, but it would be really nice if navigation could be intercepted and a confirmation dialog could be shown for when the user has some unsaved changes.

Of course the beforeunload event works, but only for when the user is closing the page,not when using client side navigation.

If there's a way to make this work right now, I'd really appreciate any tips

Indeed, I don't think it's possible and I can't think of a workaround.

What exactly would that confirmation dialog work?
