Notifications API
The Notifications API is a web platform API that allows web applications to display system-level notifications to users, even when the application is not in focus. It enables developers to send alerts, reminders, or updates directly to the user's desktop or mobile device, enhancing user engagement and providing timely information. This API is part of the broader Web APIs suite and is supported by modern browsers.
Developers should learn the Notifications API when building web applications that require real-time user alerts, such as messaging apps, email clients, calendar tools, or news platforms, to improve user experience and retention. It is particularly useful for Progressive Web Apps (PWAs) that aim to provide native-like functionality, as it allows for background notifications similar to mobile apps. Use cases include notifying users of new messages, upcoming events, or system updates without requiring them to keep the app open.
