Migrate LogView.vue to PlatformServiceMixin with architectural compliance
Achieve total architectural compliance by eliminating both legacy database utilities and direct SQL queries from LogView.vue component. **Component Changes (LogView.vue):** - Replace databaseUtil.memoryLogs with this.$memoryLogs - Replace direct SQL query with this.$logs() abstraction - Remove PlatformServiceFactory and databaseUtil imports - Add PlatformServiceMixin to component mixins - Reduce component from database-aware to pure presentation layer **Mixin Enhancements (PlatformServiceMixin.ts):** - Add $memoryLogs computed property for memory logs access - Add $logs() method for abstracted database log retrieval - Update TypeScript interfaces (IPlatformServiceMixin, ComponentCustomProperties) - Enable components to access logs without SQL knowledge **Documentation:** - Add docs/migration-testing/TESTING_LOGVIEW.md - Quick testing guide - Add docs/migration-testing/migration-checklist-LogView.md - Comprehensive checklist - Document architectural compliance achievements and testing requirements **Architectural Benefits:** - Zero databaseUtil imports in LogView.vue - Zero direct SQL queries in component layer - Proper separation of concerns (View → Service → Database) - Reusable $logs() method for other components - Sets gold standard for future migrations **Migration Progress:** - Components using PlatformServiceMixin: 14/91 (15%) - LogView.vue achieves total architectural compliance - Reduces legacy databaseUtil imports from 52 to 51 **Testing:** Ready for testing at /logs route **Backwards Compatible:** Yes - no functional changes to end users

# LogView.vue Migration Testing Guide
|
||||
|
||||
## Quick Test (2025-07-06)
|
||||
|
||||
### Migration Summary
|
||||
- **Component**: LogView.vue (110 lines)
|
||||
- **Migration Type**: Database operations + Mixin Enhancement + Architecture Improvement
|
||||
- **Total Compliance**: ✅ **ACHIEVED** - Zero databaseUtil imports + Zero direct SQL queries
|
||||
- **Changes Made**:
|
||||
- **Enhanced PlatformServiceMixin**: Added `$memoryLogs` computed property
|
||||
- **Enhanced PlatformServiceMixin**: Added `$logs()` method for abstracted log retrieval
|
||||
- **Replaced**: `databaseUtil.memoryLogs` with `this.$memoryLogs`
|
||||
- **Replaced**: Direct SQL query with `this.$logs()` abstraction
|
||||
- **Eliminated**: All direct databaseUtil imports and SQL queries
|
||||
|
||||
### Architectural Improvement
|
||||
🏗️ **No More Direct SQL in Components**: LogView.vue now uses `this.$logs()` instead of raw SQL queries, following proper layered architecture principles.
|
||||
|
||||
### Test URL
|
||||
```
|
||||
http://localhost:3000/logs
|
||||
```
|
||||
|
||||
### Expected Behavior
|
||||
1. **Loading State**: Should show spinner while loading
|
||||
2. **Memory Logs Section**: Should display memory logs at bottom (via `this.$memoryLogs`)
|
||||
3. **Database Logs**: Should display logs from database in reverse chronological order (via `this.$logs()`)
|
||||
4. **Error Handling**: Should show error message if database query fails
|
||||
|
||||
### Test Steps
|
||||
1. Navigate to `/logs`
|
||||
2. Verify page loads without errors
|
||||
3. Check that memory logs are displayed at bottom
|
||||
4. Verify database logs are shown (if any exist)
|
||||
5. Check browser console for any errors
|
||||
|
||||
### Success Criteria
|
||||
- ✅ Page loads successfully
|
||||
- ✅ Memory logs section appears (populated from `this.$memoryLogs`)
|
||||
- ✅ Database logs load without errors (retrieved via `this.$logs()`)
|
||||
- ✅ No TypeScript/JavaScript errors in console
|
||||
- ✅ UI matches expected behavior
|
||||
- ✅ **Total Compliance**: No databaseUtil imports remaining
|
||||
- ✅ **Architectural Compliance**: No direct SQL queries in component
|
||||
|
||||
### Migration Details
|
||||
- **File**: `src/views/LogView.vue`
|
||||
- **Lines Changed**: 4 lines (imports, method calls)
|
||||
- **Backwards Compatible**: Yes
|
||||
- **Database Operations**: Pure PlatformServiceMixin (`$logs`, `$memoryLogs`)
|
||||
- **Mixin Enhancement**: Added `$memoryLogs` computed property + `$logs()` method
|
||||
|
||||
### Mixin Enhancement
|
||||
**NEW**: Enhanced PlatformServiceMixin with:
|
||||
```typescript
|
||||
// Added to PlatformServiceMixin computed properties
|
||||
$memoryLogs(): string[] {
|
||||
return memoryLogs;
|
||||
}
|
||||
|
||||
// Added to PlatformServiceMixin methods
|
||||
async $logs(): Promise<Array<Record<string, unknown>>> {
|
||||
return await this.$query("SELECT * FROM logs ORDER BY date DESC");
|
||||
}
|
||||
```
|
||||
|
||||
This enables **total architectural compliance** - components no longer need databaseUtil imports OR direct SQL queries.

|
||||
- **Component**: LogView.vue
|
||||
- **Migration Date**: 2025-07-06
|
||||

|
||||
- **File Size**: 110 lines (small component)
|
||||
- **Complexity**: Low
|
||||
- **Total Compliance**: ✅ **ACHIEVED** - Zero databaseUtil imports + Zero direct SQL queries
|
||||

||||
|
||||
### 3. Database Operations Migrated
|
||||
- ✅ **Memory Logs**: `memoryLogs` → `this.$memoryLogs`
|
||||
- ✅ **Database Queries**: Direct SQL query → `this.$logs()` abstraction
|
||||
|
||||
### 4. Mixin Enhancement
|
||||
- ✅ **Added**: `$memoryLogs` computed property to PlatformServiceMixin
