ImageMethodDialog.vue Pre-Migration Audit

Component Overview

• File: src/components/ImageMethodDialog.vue
• Size: 750 lines (High Complexity)
• Purpose: Image upload and camera capture dialog component
• Migration Target: Enhanced Triple Migration Pattern

Database Operations Analysis

Phase 1: Database Migration Requirements

Current databaseUtil Usage:

1. databaseUtil.retrieveSettingsForActiveAccount() - Line 267, 340
   • Migration: → this.$accountSettings()
   • Usage: Get active DID for user authentication
   • Context: Component initialization in mounted() lifecycle hook

Additional Database Operations:

• PlatformServiceFactory.getInstance() - Line 268
• These are already using service patterns but need PlatformServiceMixin integration

Phase 2: SQL Abstraction Assessment

Status: ✅ No raw SQL queries identified

• Component uses high-level database utilities
• No direct SQL statements requiring abstraction

Phase 3: Notification Migration Analysis

Current Notification Patterns (3 total notifications):

1. Error Notifications (2 instances):

   • Settings retrieval error (Line 340-350)
   • Image URL retrieval error (Line 420-430)

2. Info Notifications (1 instance):

   • General error handling

Migration Requirements:

• Extract all notification messages to constants
• Implement helper system for consistent timeouts
• Standardize error message formats

Phase 4: Template Streamlining Assessment

Template Complexity: Medium - Some complex inline expressions

Candidates for Computed Properties:

1. Camera State Management:

   • Camera state validation logic
   • Camera mode switching logic

2. File Upload States:

   • File validation states
   • Upload progress states

3. Dialog State Management:

   • Dialog visibility logic
   • Component state validation

4. Platform Detection:

   • Platform capability checks
   • Feature availability logic

Component Feature Analysis

Core Features

• Image Upload: File selection and upload functionality
• Camera Capture: Real-time camera preview and capture
• Image Cropping: Vue Picture Cropper integration
• URL Input: Direct URL input for images
• Platform Detection: Capacitor and web platform handling
• Error Handling: Comprehensive error scenarios
• State Management: Complex state transitions

External Dependencies

• Vue Picture Cropper: Image cropping functionality
• Capacitor: Mobile platform detection
• Axios: HTTP requests for image uploads
• MediaDevices API: Camera access and management
• File API: File handling and processing

Technical Complexity Indicators

• 3 notification calls requiring standardization
• Complex state management with multiple camera states
• External API integration with error handling
• Platform-specific code for mobile/web
• File handling with multiple input methods
• Camera lifecycle management with cleanup

Migration Complexity Assessment

Complexity Rating: High

• Component Size: 750 lines
• Database Operations: 1 pattern requiring migration
• Notification Patterns: 3 calls requiring standardization
• Template Complexity: Some candidates for computed properties
• External Dependencies: High integration complexity

Estimated Migration Time

• Conservative Estimate: 20-30 minutes
• Optimistic Estimate: 15-20 minutes
• High Estimate: 30-40 minutes

Risk Factors

1. Platform Integration: Complex platform-specific code
2. Camera Management: Real-time camera state handling
3. File Processing: Multiple file input methods
4. External Dependencies: Vue Picture Cropper integration
5. State Management: Complex component state transitions

Migration Strategy

Phase 1: Database Migration

1. Add PlatformServiceMixin to mixins array
2. Replace databaseUtil.retrieveSettingsForActiveAccount() → this.$accountSettings()
3. Ensure PlatformServiceFactory integration works with mixin
4. Add comprehensive JSDoc documentation

Phase 2: SQL Abstraction

• ✅ No raw SQL queries to migrate
• Verify service layer integration works correctly

Phase 3: Notification Migration

1. Import notification constants from @/constants/notifications
2. Implement notification helper system
3. Replace all 3 $notify calls with standardized helpers
4. Use appropriate timeout constants for different message types

Phase 4: Template Streamlining

1. Extract camera state logic to computed properties
2. Create file upload state computed properties
3. Implement dialog state computed properties
4. Simplify platform detection logic
