Window: appinstalled event

The appinstalled event of the Web Manifest API is fired when the browser has successfully installed a page as an application.

Examples

You can use the appinstalled event in an addEventListener method:

window.addEventListener('appinstalled', function() { 
  console.log('Thank you for installing our app!'); 
});

Or use the onappinstalled event handler property:

window.onappinstalled = function() { 
  console.log('Thank you for installing our app!'); 
};
