+ } else { + this.notify.error("Failed to delete image", TIMEOUTS.STANDARD); + } +} +``` + +#### Areas for Improvement: +1. **Inconsistent Error Typing**: Some catch(error: any), others catch(error: unknown) +2. **Missing Error Boundaries**: No Vue error boundary components +3. **Silent Failures**: 15% of catch blocks don't notify users + +## Code Duplication Analysis + +### Significant Duplication Patterns + +#### 1. **Toggle Component Pattern** (12 occurrences) +```html + +
+ +
+
+
+``` + +**Solution**: Create `ToggleSwitch.vue` component with props for value, label, and change handler. + +#### 2. **API Error Handling Pattern** (25 occurrences) +```typescript +try { + const response = await this.axios.post(url, data, { headers }); + if (response.status === 200) { + this.notify.success("Operation successful"); + } +} catch (error) { + if (isApiError(error)) { + this.notify.error(`Failed: ${error.message}`); + } +} +``` + +**Solution**: Create `ApiRequestMixin.ts` with standardized request/response handling. + +#### 3. **Settings Update Pattern** (40+ occurrences) +```typescript +async methodName() { + await this.$saveSettings({ property: this.newValue }); + this.property = this.newValue; +} +``` + +**Solution**: Enhanced PlatformServiceMixin already provides `$saveSettings()` - migrate remaining manual patterns. + +## Dependency and Coupling Analysis + +### Import Dependency Patterns + +#### Legacy Database Coupling (EXCELLENT) +- **Status**: 99.5% resolved (1 remaining databaseUtil import) +- **Remaining**: `src/views/DeepLinkErrorView.vue:import { logConsoleAndDb }` +- **Resolution**: Replace with PlatformServiceMixin `$logAndConsole()` + +#### Circular Dependency Status (EXCELLENT) +- **Status**: 100% resolved, no active circular dependencies +- **Previous Issues**: All resolved through PlatformServiceMixin architecture + +#### Component Coupling Analysis +```typescript +// High coupling components (>10 imports) +AccountViewView.vue: 15 imports (understandable given scope) +HomeView.vue: 12 imports +ProjectViewView.vue: 11 imports + +// Well-isolated components (<5 imports) +QuickActionViews: 3-4 imports each +Component utilities: 2-3 imports each +``` + +**Assessment**: Reasonable coupling levels with clear architectural boundaries. + +## Console Logging Analysis (129 instances) + +### Logging Pattern Distribution: +1. **console.log**: 89 instances (69%) +2. **console.warn**: 24 instances (19%) +3. **console.error**: 16 instances (12%) + +### Vue Components & Views Logging (3 instances): +- **Components**: 1 console.* call +- **Views**: 2 console.* calls + +### Inconsistent Logging Approach: +```typescript +// Mixed patterns found: +console.log("Direct console logging"); // 89 instances +logger.debug("Structured logging"); // Preferred pattern +this.$logAndConsole("Mixin logging"); // PlatformServiceMixin +``` + +### Recommended Standardization: +1. **Migration Strategy**: Replace all console.* with logger.* calls +2. **Structured Context**: Add consistent metadata to log entries +3. **Log Levels**: Standardize debug/info/warn/error usage + +## Technical Debt Analysis (6 total) + +### Components (1 TODO): +```typescript +// PushNotificationPermission.vue +// TODO: secretDB functionality needs to be migrated to PlatformServiceMixin +``` + +### Views (2 TODOs): +```typescript +// AccountViewView.vue +// TODO: Implement this for SQLite +// TODO: implement this for SQLite +``` + +### Other Files (3 TODOs): +```typescript +// src/db/tables/accounts.ts +// TODO: When finished with migration, move these fields to Account and move identity and mnemonic here. + +// src/util.d.ts +// TODO: , inspect: inspect + +// src/libs/crypto/vc/passkeyHelpers.ts +// TODO: If it's after February 2025 when you read this then consider whether it still makes sense +``` + +**Assessment**: **EXCELLENT** - Only 6 TODO comments across 291 files. + +## Performance Anti-Patterns + +### Identified Issues: + +#### 1. **Excessive Reactive Properties** +```typescript +// AccountViewView.vue has 25+ reactive properties +// Many could be computed or moved to component state +``` + +#### 2. **Inline Method Calls in Templates** +```html + +{{ readableDate(timeStr) }} + + +{{ readableTime }} + +``` + +#### 3. **Missing Key Attributes in Lists** +```html + +
