🎯 Enhanced Triple Migration Pattern Analysis

📊 Phase 1: Database Migration (3-4 minutes)

Target: Replace legacy database patterns with PlatformServiceMixin

Legacy Patterns Found:

• ✅ databaseUtil Import: import * as databaseUtil from "../db/databaseUtil";
• ✅ databaseUtil Usage: databaseUtil.updateDefaultSettings() in showNotificationChoice()
• ✅ Missing PlatformServiceMixin: Component not using modern database patterns

Migration Actions Required:

1. Add PlatformServiceMixin to component mixins
2. Replace databaseUtil.updateDefaultSettings() with this.$updateSettings()
3. Remove legacy databaseUtil import
4. Add comprehensive component documentation

Estimated Time: 3-4 minutes

📊 Phase 2: SQL Abstraction (1 minute)

Target: Replace raw SQL with service methods

Analysis:

• ✅ No Raw SQL: Component uses utility functions only
• ✅ Service Layer: Already uses appropriate abstraction level
• ✅ Database Operations: Limited to settings updates only

Migration Actions Required:

• Verify no raw SQL queries exist
• Confirm service method compatibility
• Document abstraction compliance

Estimated Time: 1 minute

📊 Phase 3: Notification Migration (4-6 minutes)

Target: Replace $notify calls with helper methods + centralized constants

Legacy Patterns Found:

• ✅ 5 $notify Calls: Multiple inline notification objects
• ✅ Inline Notification Objects: All notifications defined inline
• ✅ Repeated Patterns: Similar error and success notification structures
• ✅ Missing Helper System: No notification helper system imported

Notification Patterns to Migrate:

1. Not Subscribed Error: Push subscription required message
2. Test Web Push Success: Success message for web push tests
3. Test Web Push Error: Error message for web push failures
4. Test Notification Success: Success message for direct notifications
5. Test Notification Error: Error message for direct notification failures

Migration Actions Required:

1. Add 5 notification constants to src/constants/notifications.ts
2. Import notification helper system
3. Replace all 5 $notify() calls with helper methods
4. Create helper functions for complex notification logic

Estimated Time: 4-6 minutes

📊 Phase 4: Template Streamlining (2-3 minutes)

Target: Extract repeated CSS classes and logic to computed properties

Template Patterns Found:

• ✅ Repeated CSS Classes: Long button styling repeated 5 times
• ✅ Inline Click Handlers: Multiple @click handlers that could be extracted
• ✅ Complex Template Logic: Conditional rendering and text interpolation
• ✅ Router Navigation: Inline $router.back() call

Template Optimizations Required:

1. Extract repeated button styling to computed property
2. Extract @click="$router.back()" to goBack() method
3. Extract complex click handlers to methods
4. Simplify template conditional logic

Estimated Time: 2-3 minutes
