## 🚀 Migration Readiness Assessment
|
||||
|
||||
### Pre-Migration Requirements
|
||||
- [x] **Feature audit completed**: All features documented with line numbers
|
||||
- [x] **Migration targets identified**: Each feature has clear migration path
|
||||
- [x] **Test scenarios planned**: Verification steps documented
|
||||
- [ ] **Backup created**: Original component backed up
|
||||
|
||||
### Complexity Assessment
|
||||
- [x] **Simple** (15-20 min): Few database operations, minimal notifications
|
||||
- [ ] **Medium** (30-45 min): Multiple database operations, several notifications
|
||||
- [ ] **Complex** (45-60 min): Extensive database usage, many notifications, complex templates
|
||||
|
||||
### Dependencies Assessment
|
||||
- [x] **No blocking dependencies**: Component can be migrated independently
|
||||
- [x] **Parent dependencies identified**: Called from various gift recording flows
|
||||
- [x] **Child dependencies identified**: Navigates to contact-gift route
|
||||
|
||||
## 📝 Notes and Special Considerations
|
||||
|
||||
### Special Migration Considerations
|
||||
1. **Contact Selection Algorithm**: The random contact selection logic using offset needs careful preservation
|
||||
2. **Array Indexing**: The `shownContactDbIndices` array logic must be maintained
|
||||
3. **Router Integration**: The router push with query parameters must work correctly
|
||||
4. **Callback Pattern**: The `callbackOnFullGiftInfo` callback must be preserved
|
||||
|
||||
### Risk Assessment
|
||||
- **Low Risk**: Simple database operations, no notifications, minimal template complexity
|
||||
- **Main Risk**: Ensuring random contact selection algorithm works correctly after migration
|
||||
- **Mitigation**: Thoroughly test contact carousel functionality
|
||||
|
||||
### Testing Strategy
|
||||
1. **Manual Testing**: Open dialog, cycle through ideas, test contact carousel
|
||||
2. **Router Testing**: Verify navigation to contact-gift route with prompts
|
||||
3. **Database Testing**: Verify contact count and random selection work
|
||||
4. **Edge Cases**: Test with zero contacts, single contact, many contacts
|
||||
|
||||
## 🔧 Specific Migration Steps
|
||||
|
||||
### Database Migration Steps
|
||||
1. Add PlatformServiceMixin to component
|
||||
2. Replace `PlatformServiceFactory.getInstance()` with `this.$contacts()`
|
||||
3. Replace contact count query with `this.$contacts().length`
|
||||
4. Replace random selection with array indexing on `this.$contacts()`
|
||||
5. Remove `databaseUtil.mapQueryResultToValues()` (not needed)
|
||||
|
||||
### Template Streamlining Steps
|
||||
1. Extract repeated button classes to computed property
|
||||
2. Extract contact name display logic to computed property
|
||||
3. Extract router configuration to computed property
|
||||
4. Add JSDoc comments for all computed properties
|
||||
|
||||
### Verification Steps
|
||||
1. Test idea carousel navigation (prev/next buttons)
|
||||
2. Test contact carousel navigation and skip functionality
|
||||
3. Test "That's it!" button with both ideas and contacts
|
||||
4. Test dialog cancel functionality
|
||||
5. Test router navigation with prompt query parameter
