Overview
The Push API enables servers to send data to a Service Worker. This is the foundation for web-based push notifications. It works in conjunction with the Notifications API, which is used to actually display the message to the user.
How it Works
- Subscription: The user grants permission, and the browser generates a unique endpoint.
- Push: The server sends a message to that endpoint via a push service.
- Wake up: The browser wakes up the Service Worker to handle the incoming message.
Use Cases
- Real-time alerts and news updates.
- Chat message notifications.
- Re-engaging users with personalized content.
