# DataExportSection.vue Migration Audit |
||||
|
|
||||
|
## Component Overview |
||||
|
- **File**: `src/components/DataExportSection.vue` |
||||
|
- **Size**: 163 lines (Medium Complexity) |
||||
|
- **Purpose**: Data export and seed backup functionality with platform-specific behavior |
||||
|
- **Migration Target**: Enhanced Triple Migration Pattern |
||||
|
|
||||
|
## Migration Status: ⏳ READY FOR MIGRATION |
||||
|
|
||||
|
### Pre-Migration Analysis |
||||
|

||||
|
- **SQL Queries**: ✅ No raw SQL queries found |
||||
|

||||
|
- **Template Complexity**: ⏳ Needs Phase 4 (Template Streamlining) |
||||
|
|
||||
|
### Migration Requirements |
||||
|
- ✅ **Phase 1**: Database Migration - NOT NEEDED (already migrated) |
||||
|
- ✅ **Phase 2**: SQL Abstraction - NOT NEEDED (no raw SQL) |
||||
|
- ✅ **Phase 3**: Notification Migration - NOT NEEDED (already modern) |
||||
|
- ⏳ **Phase 4**: Template Streamlining - NEEDED (long CSS classes) |
||||

||||
|
- **Testing Requirements**: Export functionality, platform detection |
||||
|
|
||||
|
### Migration Strategy |
||||
|
1. **Phase 4 Focus**: Extract long CSS classes to computed properties |
||||
|
2. **Documentation**: Enhance existing documentation |
||||
|
3. **Template Cleanup**: Improve template readability |
||||
|
4. **Validation**: Ensure export functionality remains intact |
||||
|
|
||||
|
### Success Criteria |
||||

||||
|
- ✅ Template complexity reduced |
||||
|
- ✅ Export functionality preserved |
||||
|
- ✅ Platform-specific behavior maintained |
||||
|
- ✅ Error handling preserved |
||||
|

||||
|
|
||||
|
### Next Steps |
||||
|

||||
|
- ⏳ Extract CSS classes to computed properties |
||||
|
- ⏳ Update documentation |
||||
