# IdentitySwitcherView.vue Migration Documentation

**Migration Start**: 2025-07-08 11:15 UTC  
**Component**: IdentitySwitcherView.vue  
**Priority**: High (Critical User Journey)  
**Location**: `src/views/IdentitySwitcherView.vue`

## Pre-Migration Analysis

### 🔍 **Current State Assessment**

#### Database Operations
- **✅ Already Migrated**: Uses `$accountSettings()`, `$saveSettings()`, `$exec()`
- **✅ PlatformServiceMixin**: Already imported and used as mixin
- **✅ No Legacy Code**: No databaseUtil or raw SQL found

#### Notification Usage
- **✅ Mostly Migrated**: Uses notification helpers and constants
- **⚠️ One Remaining**: Direct `$notify` call in `deleteAccount` method
- **✅ Constants Available**: All required notification constants exist

#### Template Complexity
- **✅ Already Streamlined**: Has computed properties for CSS classes
- **✅ Helper Methods**: Has `formatAccountForDisplay` method
- **✅ Clean Template**: Well-organized with computed properties

### 📋 **Migration Requirements**

#### 1. Database Migration
- [x] **COMPLETE**: All database operations use PlatformServiceMixin
- [x] **COMPLETE**: No legacy databaseUtil usage
- [x] **COMPLETE**: No raw SQL queries

#### 2. SQL Abstraction
- [x] **COMPLETE**: All database operations use service methods
- [x] **COMPLETE**: Proper parameterized queries

#### 3. Notification Migration
- [x] **COMPLETE**: Notification helpers initialized
- [x] **COMPLETE**: Most notifications use helper methods
- [ ] **REMAINING**: Replace one direct `$notify` call in `deleteAccount`

#### 4. Template Streamlining
- [x] **COMPLETE**: Computed properties for CSS classes
- [x] **COMPLETE**: Helper methods for data formatting
- [x] **COMPLETE**: Clean template structure

## Migration Plan

### 🎯 **Step 1: Complete Notification Migration**
Replace the remaining direct `$notify` call with a helper method:

```typescript
// Before
this.$notify(
  {
    group: "modal",
    type: "confirm",
    title: NOTIFY_DELETE_IDENTITY_CONFIRM.title,
    text: NOTIFY_DELETE_IDENTITY_CONFIRM.text,
    onYes: async () => {
      await this.$exec(`DELETE FROM accounts WHERE id = ?`, [id]);
      this.otherIdentities = this.otherIdentities.filter(
        (ident) => ident.id !== id,
      );
    },
  },
  -1,
);

// After
this.notify.confirm(
  NOTIFY_DELETE_IDENTITY_CONFIRM.text,
  async () => {
    await this.$exec(`DELETE FROM accounts WHERE id = ?`, [id]);
    this.otherIdentities = this.otherIdentities.filter(
      (ident) => ident.id !== id,
    );
  },
  -1
);
```
