Web Push
Web Push is a web platform API that enables websites to send push notifications to users' devices, even when the browser is not open, by leveraging service workers and push services. It allows developers to re-engage users with timely updates, alerts, or promotional content directly from a web application. This technology works across various browsers and operating systems, providing a native-like notification experience on the web.
Developers should learn Web Push to implement user engagement features in web applications, such as sending news alerts, e-commerce promotions, or real-time updates (e.g., for messaging apps or sports scores). It is particularly useful for progressive web apps (PWAs) to increase user retention and drive traffic by delivering notifications without requiring the app to be actively running. Use cases include media sites, online stores, and productivity tools where timely information delivery enhances the user experience.
