Window.onappinstalled

Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The onappinstalled attribute of the Window object serves as an event handler for the appinstalled event, which is dispatched once the web application is successfully installed as a progressive web app. The event that is fired is a "simple event" that implements the Event interface. 

Syntax

window.onappinstalled = function(event) { ... };

Example

window.onappinstalled = function(ev) { 
  console.log('The application was installed.');
};
