|
|
|
|
## 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 classes
|
|
- `cameraFrameClasses`: Camera frame CSS classes
|
|
- `mainContentClasses`: Main content container CSS classes
|
|
- `hasEthrDid`: User has ETHR DID boolean logic
|
|
- `hasAnyDid`: User has any DID boolean logic
|
|
- `shouldShowNameWarning`: Show name setup warning boolean logic
|
|
- Updated template to use computed properties instead of inline expressions
|
|
|
|
## Key Improvements
