Push API
The Push API is a web platform API that enables web applications to receive server-sent messages (push notifications) even when the app is not active in the browser. It works in conjunction with service workers to deliver real-time updates, such as news alerts, chat messages, or event reminders, directly to users' devices. This allows for engaging user experiences by keeping apps updated without requiring constant user interaction.
Developers should learn the Push API when building progressive web apps (PWAs) or any web application that requires real-time notifications to enhance user engagement and retention. It is particularly useful for news sites, social media platforms, e-commerce apps, and messaging services where timely updates are critical. By implementing push notifications, developers can re-engage users, drive traffic, and improve app functionality without native app dependencies.
