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.');
};
