Final Error Fixes - October 10, 2025

Round 2 Fixes - Remaining Errors Resolved

1. Unused Import Warnings ✅

Flash Persistence Guide Component

• Fixed: Removed unused JsonPipe, inject, computed, and ThemeApplicationService imports
• File: flash-persistence-guide.component.ts
• Action: Kept only signal and FormsModule

Statistics Modal Component

• Fixed: Removed unused JsonPipe import
• File: statistics-modal.component.ts
• Action: Changed imports: [JsonPipe] to imports: []

2. Theme System Import Paths ✅

Issue: Components were using @theme-system which doesn't exist in path mappings

Fixed Files:

• add-data-modal.component.ts
• flash-persistence-demo.component.ts
• intelligent-storage-demo.component.ts

Solution: Changed all imports from:

import { ThemeApplicationService } from '@theme-system';

To:

import { ThemeApplicationService } from '@theme-runtime';

3. SCSS Import Paths ✅

Issue: storage-inspector.component.scss was using incorrect relative paths

Fixed: Changed from:

@use '../../../../../../theme-system/theme-styles/src/lib/styles/utilities/_index' as utilities;

To:

@use '@theme-styles/scss/utilities/_index' as utilities;

Files Updated:

• storage-inspector.component.scss
• Updated 3 SCSS imports to use path mappings

4. TypeScript Type Errors ✅

Flash Persistence Demo - clearAllData()

Issue: Setting signals to empty objects {} when they expect specific interfaces

Fixed: Changed clearAllData() to properly reset with typed default values:

clearAllData(): void {
  this.userPreferences.set({
    theme: 'dark',
    language: 'en',
    notifications: true,
    autoSave: false
  });
  this.appState.set({
    currentPage: 'home',
    lastVisit: new Date().toISOString(),
    visitCount: 0
  });
  this.todoList.set([]);
}

5. MongoDB Config - process.env ✅

Issue: process is not defined in browser context

Fixed: Added runtime check before accessing process.env:

connectionString: (typeof process !== 'undefined' && process.env?.['MONGODB_CONNECTION_STRING']) || '',
defaultDatabase: (typeof process !== 'undefined' && process.env?.['MONGODB_DATABASE']) || 'storage-system',

File: environments/mongodb.config.ts
