ImportDerivedAccountView.vue Migration Documentation

Migration Start: 2025-07-08 12:33 UTC
Component: ImportDerivedAccountView.vue
Priority: High (Critical User Journey)
Location: src/views/ImportDerivedAccountView.vue

Pre-Migration Analysis

🔍 Current State Assessment

Database Operations

Legacy Pattern: Uses databaseUtil.updateDidSpecificSettings() (line 158)
Direct PlatformService: Uses PlatformServiceFactory.getInstance() (line 155)
Raw SQL: Uses "UPDATE settings SET activeDid = ?" (line 156)
No PlatformServiceMixin: Component does not use the mixin

Notification Usage

No Direct $notify Calls: Component lacks user-facing notifications
Missing User Feedback: Only error logging, no success/error notifications
No Notification Infrastructure: No helpers or constants imported

Template Complexity

Conditional Rendering: DID selection and account grouping
Dynamic Content: Account arrays, derivation paths, selection states
User Interactions: Account switching, derivation increment, import process

📊 Migration Complexity Assessment

Database Migration: Medium (2 database operations)
SQL Abstraction: Low (1 raw SQL query)
Notification Migration: High (needs complete notification system)
Template Streamlining: Low (template is already clean)

🎯 Migration Goals

Replace databaseUtil calls with PlatformServiceMixin methods
Abstract raw SQL with service methods
Add comprehensive notification system for user feedback
Replace direct PlatformServiceFactory usage with mixin methods
Add proper error handling with user notifications

Migration Plan

Phase 1: Database Migration

// Replace databaseUtil.updateDidSpecificSettings()
await this.$saveUserSettings(newId.did, { isRegistered: false });

// Replace PlatformServiceFactory.getInstance() + raw SQL
await this.$setActiveDid(newId.did);

Phase 2: Notification Migration

// Add notification constants
NOTIFY_ACCOUNT_DERIVATION_SUCCESS
NOTIFY_ACCOUNT_DERIVATION_ERROR
NOTIFY_ACCOUNT_IMPORT_SUCCESS

// Add notification infrastructure
import { createNotifyHelpers, TIMEOUTS } from "@/utils/notify";
import {
  NOTIFY_ACCOUNT_DERIVATION_SUCCESS,
  NOTIFY_ACCOUNT_DERIVATION_ERROR,
  NOTIFY_ACCOUNT_IMPORT_SUCCESS,
} from "@/constants/notifications";

// Add property and initialization
notify!: ReturnType<typeof createNotifyHelpers>;

created() {
  this.notify = createNotifyHelpers(this.$notify);
}

Phase 3: Error Handling Enhancement

// Add success notifications
this.notify.success(NOTIFY_ACCOUNT_DERIVATION_SUCCESS.message, TIMEOUTS.STANDARD);

// Add error notifications
this.notify.error(NOTIFY_ACCOUNT_DERIVATION_ERROR.message, TIMEOUTS.LONG);

Migration Implementation

Step 1: Add PlatformServiceMixin

import { PlatformServiceMixin } from "@/utils/PlatformServiceMixin";

@Component({
  components: {},
  mixins: [PlatformServiceMixin],
})

Step 2: Add Notification Infrastructure

import { createNotifyHelpers, TIMEOUTS } from "@/utils/notify";
import {
  NOTIFY_ACCOUNT_DERIVATION_SUCCESS,
  NOTIFY_ACCOUNT_DERIVATION_ERROR,
  NOTIFY_ACCOUNT_IMPORT_SUCCESS,
} from "@/constants/notifications";

// Add property
notify!: ReturnType<typeof createNotifyHelpers>;

// Initialize in created()
created() {
  this.notify = createNotifyHelpers(this.$notify);
}

Step 3: Replace Database Operations

// In incrementDerivation() method
await this.$saveUserSettings(newId.did, { isRegistered: false });
await this.$setActiveDid(newId.did);

Step 4: Add Notification Calls

// Success notification after import
this.notify.success(NOTIFY_ACCOUNT_DERIVATION_SUCCESS.message, TIMEOUTS.STANDARD);

// Error notification in catch block
this.notify.error(NOTIFY_ACCOUNT_DERIVATION_ERROR.message, TIMEOUTS.LONG);

Expected Outcomes

Technical Improvements

✅ All database operations use PlatformServiceMixin
✅ No raw SQL queries in component
✅ Comprehensive notification system for user feedback
✅ Proper error handling with user notifications
✅ Consistent error handling patterns

Functional Preservation

✅ Account derivation and import preserved
✅ DID selection and switching preserved
✅ Navigation and routing preserved
✅ Error handling enhanced with user feedback
✅ All cryptographic operations preserved

Performance Improvements

✅ Reduced database query complexity
✅ Standardized notification patterns
✅ Better error handling efficiency
✅ Enhanced user experience with feedback

Testing Requirements

Functional Testing

Account derivation works correctly
DID selection and switching works
Import process completes successfully
Error handling displays appropriate notifications
Navigation works correctly after import

Cross-Platform Testing

Web browser functionality
Mobile app functionality (Capacitor)
Desktop app functionality (Electron)
PWA functionality

Error Scenario Testing

Network connectivity issues
Invalid derivation paths
Database connection issues
Cryptographic operation failures
Settings update failures

Security Audit Checklist

SQL Injection Prevention

No raw SQL queries in component
All database operations use parameterized queries
Input validation for derivation paths
Proper error handling without information disclosure

Data Privacy

Account data handled securely
Cryptographic operations secure
No sensitive data in error messages
Settings data properly validated

Input Validation

Derivation paths validated
DID identifiers validated
Account metadata validated
Cryptographic inputs validated

Migration Timeline

Estimated Duration: 20-25 minutes

Phase 1 (Database): 5-7 minutes
Phase 2 (SQL): 2-3 minutes
Phase 3 (Notifications): 8-10 minutes
Phase 4 (Error Handling): 5-5 minutes

Risk Assessment

Functionality Risk: Low (account derivation is well-contained)
Data Risk: Low (read-only operations with controlled updates)
User Impact: Medium (account import is important workflow)

Dependencies

PlatformServiceMixin availability
Notification constants in place
Cryptographic utility functions preserved
Account management functions accessible

Migration Status

Implementation Status
