How Notifications Are Created

Pattern 1: Direct Insert (Server Endpoints)

await adminSupabase.from("notifications").insert({
  user_id: targetUserId,
  type: "info",
  title: "Notification Title",
  message: "Notification message",
});

Pattern 2: Service Method (Client Services)

await aethexNotificationService.createNotification(
  userId,
  "success",
  "Title",
  "Message",
);

Pattern 3: Trigger Utilities (Client)

await notificationTriggers.postLiked(userId, likerName);

Performance Considerations

1. Non-Blocking: Notifications don't block main operations

2. Batch Inserts: Multiple staff notifications inserted in batch

3. Lazy Loading: Only latest 20 notifications fetched initially

4. Real-Time Subscription: Efficient WebSocket streaming

5. Error Handling: Notification failures don't crash main operation

• Bell icon with unread count badge
