Invitations : Être notifi-é-e des changements d'un événement

[Palingenae]

User Story

As an authenthicated User who is a guest to an event,
I want to be able to receive notifations when an event is updated

Dependencies

• Requires MailGun or SendGrid to send emails
• Requires MailDev for testing
• FireBase Cloud Messaging ( FCM)

Technical Tasks:

-FCM Integration: Integrate Firebase Cloud Messaging into the application for push notifications if it's not already set up.

• Backend Trigger for Event Update: Implement a trigger on the backend to detect when an event has been updated. This can be part of the existing event update logic.
• Notification Payload: Define the payload for the notification, which should include all necessary details about the event update.
• Notification Sending: Once an event is updated, use FCM to send a push notification to all guests of the event.
• Database Schema Update: Ensure the database schema supports tracking which users should receive notifications for which events.
• Authentication and Authorization: Ensure that only authenticated users who are guests for the specific event will receive notifications.
• Error Handling: Implement error handling to manage any issues that may arise during the notification process, such as failures in sending notifications through FCM.

Acceptance Criteria:

• FCM Integration: Firebase Cloud Messaging should be integrated correctly into the application for push notifications.
• Notification Receipt: Authenticated users who are guests of an updated event should receive a push notification about the update.
• Notification Content: The push notification should provide sufficient details about what aspect of the event was updated (e.g., time, location, etc.).
• Authentication and Authorization: Only authenticated users who are guests for the specific event should receive the update notifications.
• Error Handling and Feedback: Any errors in the process of sending notifications, like FCM failures, should be logged for future debugging. The application should handle these errors gracefully.
• Timeliness: Notifications should be received promptly after an event is updated.
