It seems you are looking for canDeactivate
It allows you to block routing away. You would need a shared service where you update the forms dirty state so that the guard can access it.
The angular docs cover this exact question:
https://angular.io/guide/router#candeactivate-handling-unsaved-changes I'd leave that as a comment but I lack the reputation to do so.
