On supported platforms, showing a system notification generally involves two things. First, the user needs to grant the current origin permission to display system notifications, which is generally done when the app or site initializes, using the Notification.requestPermission() method. This method should only be called when handling a user gesture, such as when handling a mouse click. For example:
btn.addEventListener("click", () => {
let promise = Notification.requestPermission();
// wait for permission
});
This will spawn a request dialog, along the following lines:
From here the user can choose to allow notifications from this origin, or block them. Once a choice has been made, the setting will generally persist for the current session.
Next, a new notification is created using the Notification() constructor. This must be passed a title argument, and can optionally be passed an options object to specify options, such as text direction, body text, icon to display, notification sound to play, and more.
In addition, the Notifications API spec specifies a number of additions to the ServiceWorker API, to allow service workers to fire notifications.
Note: To find out more about using notifications in your own app, read Using the Notifications API.
