Is beforeUnmountthe best solution?

[IvanWala]

Hi I am pretty newie in quasar and Vue.

I'm developing an app with quasar and I need to check if a condition is true before change of page. If this condition it's not true the use can't change of screen and a message needs to be displayed saying it.

I don't know if is possible check it in beforeUnmount because I believe it is only for animations.

As I say we don't need it checked only when a user presses the button for change to another page. We need it when he presses the back button too.

Someone can help me?

@IvanWala try one of the vue component router guards https://router.vuejs.org/guide/advanced/navigation-guards.html#in-component-guards, specifically beforeRouteLeave, see their example.
