Web Push Notifications

As time goes by, the web becomes more and more powerful. It’s been around for a while, but I think that with Chrome and Edge finally supporting PWA apps (and native apps starting to become mobile web apps), it is time to embrace this technology. It is time to create web pages that can push notifications directly to the desktop even if the browser is closed.

This works right now on any device running Microsoft Edge, as well as devices that run Google Chrome (Android devices and desktops running Chrome).

Architecturally, the Service Worker part of your website (running in the background) creates a subscription with a push notification service provider and then that “token” is sent to your application server, which will use it to send you a notification.

What I didn’t grasp, is that you the concept of the push notification service provider is not any server running some software running a specific protocol, but rather tied directly to the browser. For example, the ONLY push notification service provider if the website is being viewed within Google Chrome is FCM (Firebase), Mozilla or Microsoft Edge (Windows WNS). In fact, these are the same technologies that are used by real native apps on those platforms.

Soooo…

  1. The API to subscribe and get some sort of token to enable push notifications is defined by internet standards, so it is safe to use in any browser on any website.
  2. Each browser will implement those methods using its own push notification service provider
  3. Sending a push notification will be different depending on whom the push notification service provider is.
