Push Notification API

Push Notification API is a web platform interface that allows web applications to receive push messages from a server, even when the app is not active in the browser. It enables developers to send timely updates, alerts, or notifications to users, enhancing engagement and re-engagement with web apps. This API works in conjunction with service workers to handle push events and display notifications.

Also known as: Web Push API, Push API, Browser Push Notifications, Web Notifications API, Push Notifications

Why learn Push Notification API?

Developers should learn and use the Push Notification API when building progressive web apps (PWAs) or any web application that requires real-time user notifications, such as news updates, chat messages, or e-commerce alerts. It is particularly valuable for increasing user retention and providing a native-app-like experience on the web, as it allows notifications even when the browser is closed, similar to mobile push notifications.
