feat: Integrate Firebase Cloud Messaging (FCM) #4
Conversation
I've added Firebase Cloud Messaging capabilities to your web application.
Here are the key changes:
- I created `public/firebase-messaging-sw.js`: This handles background notifications, initializing Firebase and displaying notifications when the app is not in focus.
- I modified `src/app.ts`:
- I integrated the FCM SDK to request notification permissions from you.
- I retrieve and log/display the FCM registration token.
- I added a handler for foreground messages, displaying them directly in the app.
- I included a placeholder for the VAPID key, which you must configure.
- I updated `index.html`:
- I added new UI elements to display the FCM registration token and any notifications received while the app is in the foreground.
Here are the post-integration steps for you:
- Replace the placeholder VAPID key in `src/app.ts` with your actual key from the Firebase console.
- Ensure your Firebase project is configured for FCM, including the VAPID key.
- Test by sending messages via the Firebase console.

📋 Review Summary
This PR integrates Firebase Cloud Messaging (FCM) into the application, enabling push notifications. The changes include a new service worker for background messages and updates to the main application to handle foreground messages and token management.
🔍 General Feedback
- The implementation correctly sets up FCM and handles both background and foreground messages.
- There are some security concerns with hardcoded keys and configurations that should be addressed.
- The code could be made more maintainable by avoiding duplicated configurations.
- The user experience for foreground messages can be improved by using a less intrusive notification method.

🟡 The firebaseConfig is duplicated from src/app.ts. This can lead to inconsistencies if the configuration changes in one place but not the other. Consider creating a shared configuration file and importing it in both src/app.ts and public/firebase-messaging-sw.js to avoid duplication and ensure consistency.

🔴 The apiKey in firebaseConfig is hardcoded. This is a security risk. It should be loaded from a secure configuration or environment variables, not stored in a publicly accessible file.

🟢 The notificationclick event listener contains commented-out code. If this functionality is intended to be used, it should be implemented. Otherwise, the commented-out code should be removed to improve code clarity and reduce clutter.
