ContactQRScanFullView.vue Migration Documentation
Migration Summary
- File:
src/views/ContactQRScanFullView.vue
- Migration Date: 2025-07-09
- Migration Time: 28 minutes (2 minutes under 30-minute high estimate)
- Status: ✅ COMPLETED - Enhanced Triple Migration Pattern
- Human Testing: ✅ PASSED
- Component Type: Enhanced QR code scanner for contact information exchange
Pre-Migration Analysis
- File Size: 636 lines
- Complexity: Very High
- Database Patterns: 5 major patterns identified
- Notification Calls: 14 instances
- Raw SQL: 2 queries to replace
- Template Complexity: Complex CSS calculations and boolean logic
Migration Implementation
Phase 1: Database Migration ✅
Completed: PlatformServiceMixin integration
- Added
PlatformServiceMixin
to mixins array - Replaced
databaseUtil.retrieveSettingsForActiveAccount()
→this.$accountSettings()
- Replaced
databaseUtil.mapQueryResultToValues()
→this.$mapQueryResultToValues()
- Replaced
databaseUtil.generateInsertStatement()
→this.$generateInsertStatement()
- Added comprehensive JSDoc documentation to all methods
Phase 2: SQL Abstraction ✅
Completed: Service layer abstraction
- Replaced raw SQL query
"SELECT * FROM contacts WHERE did = ?"
→this.$getContact(contact.did)
- Replaced manual insert statement generation →
this.$insertContact(contact)
- Eliminated all raw SQL patterns for cleaner abstractions
Phase 3: Notification Migration ✅
Completed: Centralized notification constants
- Removed
NotificationIface
import and type annotation - Imported 16 notification constants from
@/constants/notifications
- Added notification helper system using
createNotifyHelpers(this.$notify)
- Replaced all 14
$notify
calls with helper methods and constants - Used proper timeout constants:
QR_TIMEOUT_LONG
,QR_TIMEOUT_MEDIUM
,QR_TIMEOUT_STANDARD
Phase 4: Template Streamlining ✅
Completed: Computed property extraction
- Created 6 computed properties for complex logic:
qrContainerClasses
: QR code container CSS classescameraFrameClasses
: Camera frame CSS classesmainContentClasses
: Main content container CSS classeshasEthrDid
: User has ETHR DID boolean logichasAnyDid
: User has any DID boolean logicshouldShowNameWarning
: Show name setup warning boolean logic
- Updated template to use computed properties instead of inline expressions
Key Improvements
Performance Enhancements
- Service layer abstractions provide better caching
- Computed properties eliminate repeated calculations
- Centralized notification system reduces overhead
Code Quality
- Eliminated inline template logic
- Comprehensive JSDoc documentation added
- Proper TypeScript integration maintained
- Clean separation of concerns
Maintainability
- Centralized notification constants
- Reusable computed properties
- Service-based database operations
- Consistent error handling patterns
Validation Results
- ✅ TypeScript compilation passes
- ✅ ESLint validation passes (0 errors, 1 warning about
any
type) - ✅ All unused imports removed
- ✅ Code formatting corrected
- ✅ Functional testing completed
