Web Push API: Engage Users When Your App is Closed
The Web Push API lets servers send messages to users even when your site is closed. A service worker receives these pushes, making it ideal for notifications. The main footgun: the subscription endpoint is a secret key that must be protected.
The Web Push API lets servers send messages to users even when your app is closed. A service worker subscribes to a push service, receiving a unique endpoint URL. Your backend sends messages to this URL, and the browser wakes the service worker to process the data, perfect for showing notifications. The main footgun is that this endpoint URL is a secret; if it leaks, anyone can send messages to that user. You must also protect your subscription logic against Cross-Site Request Forgery (CSRF).
