Web Push API
The Web Push API is a web standard that enables web applications to send push notifications to users even when the app is not active in the browser. It allows servers to deliver messages to client applications via push services, providing real-time updates and re-engagement capabilities. This API works in conjunction with service workers to handle notifications in the background.
Developers should learn the Web Push API to implement push notifications in Progressive Web Apps (PWAs) for user engagement, such as sending alerts for new messages, updates, or promotions. It's essential for applications requiring timely communication with users, like news sites, e-commerce platforms, or messaging apps, as it helps increase user retention and interaction without requiring the app to be open.
