|

|

// When your web app is in the background or closed, the browser shuts down your React app’s JS context (like your firebase.js, App.js, etc.). At this point:
|
||
// Only a Service Worker (like firebase-messaging-sw.js) is allowed to run.
|
||
// It listens for messages even when your app is not active.
|
||
// Firebase automatically routes background messages to that service worker.
|
||
// So you must use onBackgroundMessage() in the service worker.
|
||
// 🔁 Think of the service worker like a "headless background listener" running outside your React app.
|
||
|
||
