Detect url changes before they happen #35

Closed MarkNijhof closed 6 years ago

MarkNijhof commented 6 years ago

I have a form and I want to show a popup when a user wants to navigate away from the form if they have not saved it. Is there a way to have a hook in elm-route-url that will enable me to do that?

MarkNijhof commented 6 years ago

To clarify, I am especially looking for when they use the back button, so navigation triggered outside the app, the route changes triggered from within I deal with myself.

Found a different way with the help of the Elm Slack channel :-)
