We create (or invoke) the notification from the page (or from the server, in the case of push notifications).
NODE JS MAC NOTIFICATIONS HOW TO
The *Invocation API * controls how to make your notification appear, including styling and vibration. We can split the Notifications API into two core areas (these are non-technical and are not part of the spec). Where possible, it uses the same mechanisms a native app would use, giving a completely native look and feel. It is incredibly powerful and simple to use. The Notifications API lets us display notifications to the user.
When the user interacts with the notification, by clicking or closing it, the service worker wakes up for a brief time to handle the interaction before going back to sleep. Because notifications are paired with a service worker, the service worker can listen for notification interactions in the background without using resources. When it receives a message, the service worker wakes up just long enough to display the notification and then goes back to sleep.
The section on the Push API describes this process in detail. Push messages destined to become notifications are sent from a server directly to the push service, and contain the information necessary for the push service to send it to the right client and wake up the correct service worker. Browsers that support web push each implement their own push service, which is a system for processing messages and routing them to the correct clients. There are several pieces that come together to make push notifications work. You can also integrate action buttons in the notification so that the user can interact with your site or application without needing to go back to your web page. They can do simple things, such as alert the user to an important event, display an icon and a small piece of text that the user can then click to open up your site. Push notifications let your app extend beyond the browser, and are an incredibly powerful way to engage with the user. Understanding Push Notifications on the web
