I have an long operation on the page. How can I said user wait a bit when he make the navigation change?
The idea is to show the promt dialog. But the trouble prevent default Aurelia router behavior.

You could use the canDeactivate hook of your view-model. Like this:
canDeactivate() {
return confirm('Are you sure you want to leave this page?');
}
canDeactivate() - Implement this hook if you want to control whether or not the router can navigate away from your view-model when moving to a new route. Return a boolean value, a promise for a boolean value, or a navigation command.

It's only for navigating away, but what about closing browser window? – Marek M. May 13 '17 at 14:12

I suppose the answer is not specific to the Aurelia.js https://stackoverflow.com/questions/2229942/how-to-block-users-from-closing-a-window-in-javascript – Egor Malkevich Jul 25 '17 at 10:22
