App Visibility

Quasar makes use of the Page Visibility API which lets you know when a website/app is visible or in focus.

import { AppVisibility } from 'quasar'
(Boolean) AppVisibility.isVisible()

There is also an event triggered when focus changes (read about Events here):

Event Name	Parameters	Description
