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

• Database Operations: ✅ Already using PlatformServiceMixin
• SQL Queries: ✅ No raw SQL queries found
• Notification Usage: ✅ Already using modern notification helpers
• 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)

Component Features to Migrate

• Data Export: Database export to JSON file functionality
• Seed Backup: Router link to seed backup page
• Platform Detection: Platform-specific UI and behavior
• Error Handling: Comprehensive error handling with notifications
• Loading States: Export progress indication
• File Management: Platform-specific file handling

Technical Analysis

• Database Operations: Uses this.$contacts() from PlatformServiceMixin
• Notification System: Uses createNotifyHelpers with proper patterns
• Platform Service: Uses this.platformService.writeAndShareFile()
• Template Classes: 8+ long CSS classes that can be extracted
• Methods: 2 methods with good documentation
• Computed Properties: 1 computed property (fileName)

Migration Complexity Assessment

• Database Migration: Low (already migrated)
• SQL Abstraction: Low (no raw SQL)
• Notification Migration: Low (already modern)
• Template Streamlining: Medium (8+ long classes to extract)
• Overall Complexity: Low-Medium

Estimated Migration Time

• Conservative Estimate: 8-12 minutes
• Optimistic Estimate: 4-6 minutes
• Based on: Template streamlining complexity, good existing structure

Risk Assessment

• Risk Level: Low
• Potential Issues: None identified
• Dependencies: PlatformServiceMixin, notification helpers
• 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

• ✅ All long CSS classes extracted to computed properties
• ✅ Template complexity reduced
• ✅ Export functionality preserved
• ✅ Platform-specific behavior maintained
• ✅ Error handling preserved
• ✅ Lint validation passes

Next Steps

• ⏳ Begin Phase 4 (Template Streamlining)
• ⏳ Extract CSS classes to computed properties
• ⏳ Update documentation
• ⏳ Validate functionality
• ⏳ Create migration completion document
