Backend API Changes

New Endpoint: PUT /api/v1/settings

Request Body:

{
  "password": "current_password",      // Required when setting new_password
  "new_password": "new_secure_pass",  // Optional
  "timezone": "America/New_York"      // Optional
}

Response: 200 OK - Returns full SettingsResponse

Error Responses:

• 400 Bad Request - Invalid request (missing fields, invalid password)
• 401 Unauthorized - Not authenticated
• 500 Internal Server Error - Server error

Usage Examples:

1. Update password:

curl -X PUT http://localhost:8080/api/v1/settings \
  -H "Content-Type: application/json" \
  -H "Cookie: session=..." \
  -d '{"password":"oldpass","new_password":"newpass"}'

2. Update timezone:

curl -X PUT http://localhost:8080/api/v1/settings \
  -H "Content-Type: application/json" \
  -H "Cookie: session=..." \
  -d '{"timezone":"America/New_York"}'

3. Update both:

curl -X PUT http://localhost:8080/api/v1/settings \
  -H "Content-Type: application/json" \
  -H "Cookie: session=..." \
  -d '{"password":"oldpass","new_password":"newpass","timezone":"America/New_York"}'

Frontend API Changes

New Generated Function: useUpdateSettings

Type:

import { useUpdateSettings } from '../generated/anthoLumeAPIV1';

await updateSettings.mutateAsync({
  data: {
    password: 'current_password',
    new_password: 'new_password',
    timezone: 'America/New_York'
  }
});

Testing Checklist

Frontend Testing

• Verify dev server starts without errors
• Test AdminPage backup operation (success and error)

Benefits Achieved

User Experience ✅

• ✅ Consistent error messaging across all pages
• ✅ Less intrusive than alert() dialogs (no blocking UI)
• ✅ Auto-dismissing notifications (better UX)
• ✅ Stackable notifications for multiple events
• ✅ Better mobile experience (no modal blocking)
• ✅ Theme-aware styling (automatic dark/light mode)

Developer Experience ✅

• ✅ Reduced state management complexity
• ✅ Cleaner, more maintainable code
• ✅ Consistent API for showing notifications
• ✅ Type-safe with TypeScript
• ✅ Removed anti-pattern (alert())

Code Quality ✅

• ✅ Removed all alert() calls
• ✅ Removed inline error message rendering
• ✅ Follows React best practices
• ✅ Improved component reusability
• ✅ Better separation of concerns

---

Remaining Work (Optional)

authInterceptor.ts (Global Error Handling)

The authInterceptor.ts file could be enhanced to show toasts for global errors (401, 500, etc.), but this requires a global toast service or event system. This was marked as optional and not implemented.

---

Deployment Notes

Backend Deployment

1. The new PUT /settings endpoint requires:

   • No database migrations (uses existing UpdateUser query)
   • New Go dependencies: github.com/alexedwards/argon2id (verify if already present)

2. Restart the backend service to pick up the new endpoint

Frontend Deployment

1. No additional dependencies beyond clsx and tailwind-merge (already installed)
2. Build and deploy as normal
3. All toast functionality works client-side

---

API Regeneration Commands

If you need to regenerate the API in the future:

# Backend (Go)
cd /home/evanreichard/Development/git/AnthoLume
go generate ./api/v1/generate.go

# Frontend (TypeScript)
cd /home/evanreichard/Development/git/AnthoLume/frontend
npm run generate:api

---

Summary

All identified locations have been successfully migrated to use toast notifications:

• ✅ 5 pages migrated (AdminPage, AdminUsersPage, AdminImportPage, LoginPage, DocumentsPage)
• ✅ 10+ API operations now use toast notifications
• ✅ All alert() calls removed
• ✅ All inline error state removed
• ✅ Settings page TODOs implemented with new v1 API endpoint
• ✅ Backend PUT /settings endpoint created and tested
• ✅ Frontend uses new endpoint with proper error handling
• ✅ Skeleton loaders added where appropriate
• ✅ Theme-aware styling throughout

The application now has a consistent, modern error notification system that provides better UX and follows React best practices.
