The notification system has been comprehensively implemented to provide real-time feedback for all major user actions. Notifications are created for:

1. Achievements - When users earn achievements

2. Account/System Events - Onboarding completion, profile updates, level ups

3. Project/Team Activities - Team/project creation, member additions, status changes

4. OAuth/Integrations - Account linking (Discord, etc.)

Integration Points

When Notifications Are Created

Event	Service	Method	Type
Achievement earned	AethexAchievementService	awardAchievement()	success
Team created	AethexCollabService	createTeam()	success
User added to team	AethexCollabService	addTeamMember()	info
Project created	AethexProjectService	createProject()	success
User added to project	AethexCollabService	addProjectMember()	info
Project status: completed	AethexProjectService	updateProject()	success
Project status: in_progress	AethexProjectService	updateProject()	info

Onboarding completed	Onboarding page	finishOnboarding()	success
Discord linked	Discord OAuth	callback.ts	success
Profile updated (onboarded)	AethexUserService	updateProfile()	success

Error Handling

All notification creation is non-blocking:

• Wrapped in try-catch blocks

• Logged to console if failures occur

• Does not prevent main operation from completing

• User experience not affected if notifications fail

Future Enhancements

Potential notification triggers for future implementation:

1. Social Features

   • New follower

   • Post liked/commented

   • Mentioned in post

2. Collaboration

   • Task assigned

   • Comment on project

   • Team invitation

3. Notifications

   • Email verification needed

   • Session expiration warning

   • Security alerts

4. Opportunities

   • New job matching user skills

   • Opportunity application accepted

   • Referral bonus awarded

Testing the System

Manual Testing Steps

1. Achievement Notification

   • Go to Dashboard

   • Trigger an achievement (e.g., create first project for "Portfolio Creator")

   • Check NotificationBell for 🏆 icon

2. Team Notification

   • Create a new team

   • Check NotificationBell for 🎯 icon

3. Discord Linking

   • Go to Dashboard > Connections

   • Link Discord account

   • Check NotificationBell for 🔗 icon

4. Onboarding Notification

   • Sign up new account

   • Complete onboarding

   • Should see 🎉 notification after finishing

5. Real-time Test

   • Open notification bell in one tab

   • Trigger action in another tab

   • Verify real-time update in first tab

Monitoring

Check Supabase dashboard:

• Navigate to notifications table

• Filter by user_id to see all notifications for a user

• Verify type, title, message fields are populated correctly

Notification Database Schema

CREATE TABLE notifications (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  user_id UUID NOT NULL REFERENCES auth.users(id),
  type VARCHAR(50),
  title VARCHAR(255),
  message TEXT,
  read BOOLEAN DEFAULT false,
  created_at TIMESTAMP WITH TIME ZONE DEFAULT now()
);

CREATE INDEX notifications_user_id_idx ON notifications(user_id);
CREATE INDEX notifications_user_created_idx ON notifications(user_id, created_at DESC);

Performance Considerations

1. Limit notifications - Latest 20 notifications are fetched initially

2. Real-time subscription - Only listens for new inserts (not all changes)

3. Non-blocking creation - Notifications don't block main operations

4. Batch operations - Onboarding uses Promise.allSettled for parallel operations

Backward Compatibility

• All existing code continues to work

• New notification calls are backward compatible

• No breaking changes to existing APIs

• Notifications are optional enhancements

Deployment Checklist

• Notification service utilities created

• Achievement notifications implemented

• Team/project notifications implemented

• Account/system event notifications implemented

• OAuth linking notifications implemented

• Backend notification utilities created

• Discord OAuth integration updated

• Real-time subscription already working

• NotificationBell component already exists

• Database table already exists

• Test all notification flows end-to-end

• Monitor production for notification delivery
