Vue Component Quality Patterns

Excellent Patterns Found:

1. EntityIcon.vue (86 lines) ✅ EXCELLENT

// Clean, focused responsibility
@Component({ name: "EntityIcon" })
export default class EntityIcon extends Vue {
  @Prop() contact?: Contact;
  @Prop({ default: "" }) entityId!: string;
  @Prop({ default: 0 }) iconSize!: number;
  
  generateIcon(): string {
    // Clear priority order: profile image → avatar → fallback
    const imageUrl = this.contact?.profileImageUrl || this.profileImageUrl;
    if (imageUrl) return `<img src="${imageUrl}" ... />`;
    
    const identifier = this.contact?.did || this.entityId;
    if (!identifier) return `<img src="${blankSquareSvg}" ... />`;
    
    return createAvatar(avataaars, { seed: identifier, size: this.iconSize }).toString();
  }
}

2. QuickNav.vue (118 lines) ✅ EXCELLENT

// Simple, focused navigation component
@Component({ name: "QuickNav" })
export default class QuickNav extends Vue {
  @Prop selected = "";
  
  // Clean template with consistent patterns
  // Proper accessibility attributes
  // Responsive design with safe area handling
}

3. Small Focused Views ✅ EXCELLENT

// QuickActionBvcView.vue (54 lines) - Perfect size
// ConfirmContactView.vue (57 lines) - Focused responsibility
// HelpNotificationTypesView.vue (73 lines) - Clear purpose
// LogView.vue (104 lines) - Simple utility view

Problematic Patterns Found:

1. Excessive Props in Dialog Components

// GiftedDialog.vue - Too many props
@Prop() fromProjectId = "";
@Prop() toProjectId = "";
@Prop() isFromProjectView = false;
@Prop() hideShowAll = false;
@Prop({ default: "person" }) giverEntityType = "person";
@Prop({ default: "person" }) recipientEntityType = "person";
// ... 10+ more props

2. Complex State Machines

// ImageMethodDialog.vue - Complex state management
cameraState: "off" | "initializing" | "active" | "error" | "retrying" | "stopped" = "off";
showCameraPreview = false;
isRetrying = false;
showDiagnostics = false;
// ... 15+ more state properties

3. Excessive Reactive Properties

// AccountViewView.vue - Too many reactive properties
downloadUrl: string = "";
loadingLimits: boolean = false;
loadingProfile: boolean = true;
showAdvanced: boolean = false;
showB64Copy: boolean = false;
showContactGives: boolean = false;
showDidCopy: boolean = false;
showDerCopy: boolean = false;
showGeneralAdvanced: boolean = false;
showLargeIdenticonId?: string;
showLargeIdenticonUrl?: string;
showPubCopy: boolean = false;
showShortcutBvc: boolean = false;
warnIfProdServer: boolean = false;
warnIfTestServer: boolean = false;
zoom: number = 2;
isMapReady: boolean = false;
// ... 10+ more properties

File Size and Complexity Analysis (All Files)

Problematic Large Files

1. `AccountViewView.vue` (2,215 lines) 🔴 CRITICAL

Issues Identified:

Excessive Single File Responsibility: Handles profile, settings, notifications, server configuration, export/import, limits checking
Template Complexity: ~750 lines of template with deeply nested conditions
Method Proliferation: 50+ methods handling disparate concerns
State Management: 25+ reactive properties without clear organization

2. `PlatformServiceMixin.ts` (2,091 lines) ⚠️ HIGH PRIORITY

Issues Identified:

God Object Pattern: Single file handling 80+ methods across multiple concerns
Mixed Abstraction Levels: Low-level SQL utilities mixed with high-level business logic
Method Length Variance: Some methods 100+ lines, others single-line wrappers

Refactoring Strategy:

// Current monolithic mixin
PlatformServiceMixin.ts (2,091 lines)

// Proposed separation of concerns
├── CoreDatabaseMixin.ts          // $db, $exec, $query, $first (200 lines)
├── SettingsManagementMixin.ts    // $settings, $saveSettings (400 lines)
├── ContactManagementMixin.ts     // $contacts, $insertContact (300 lines)
├── EntityOperationsMixin.ts      // $insertEntity, $updateEntity (400 lines)
├── CachingMixin.ts              // Cache management (150 lines)
├── ActiveIdentityMixin.ts       // Active DID management (200 lines)
├── UtilityMixin.ts              // Mapping, JSON parsing (200 lines)
└── LoggingMixin.ts              // $log, $logError (100 lines)

3. `HomeView.vue` (1,852 lines) ⚠️ MODERATE PRIORITY

Issues Identified:

Multiple Concerns: Activity feed, projects, contacts, notifications in one file
Complex State Management: 20+ reactive properties with interdependencies
Mixed Lifecycle Logic: Mount, update, and destroy logic intertwined

File Size Distribution Analysis

Files > 1000 lines: 9 files (4.6% of codebase)
Files 500-1000 lines: 23 files (11.7% of codebase)  
Files 200-500 lines: 45 files (22.8% of codebase)
Files < 200 lines: 120 files (60.9% of codebase)

Assessment: Good distribution with most files reasonably sized, but critical outliers need attention.

Type Safety Analysis

Type Assertion Patterns

"as any" Usage (62 total instances) ⚠️

Vue Components & Views (41 instances):

// ImageMethodDialog.vue:504
const activeIdentity = await (this as any).$getActiveIdentity();

// GiftedDialog.vue:228  
const activeIdentity = await (this as any).$getActiveIdentity();

// AccountViewView.vue: Multiple instances for:
// - PlatformServiceMixin method access
// - Vue refs with complex typing
// - External library integration (Leaflet)

Other Files (21 instances):

Vue Component References (23 instances): (this.$refs.dialog as any)
Platform Detection (12 instances): (navigator as any).standalone
External Library Integration (15 instances): Leaflet, Axios extensions
Legacy Code Compatibility (8 instances): Temporary migration code
Event Handler Workarounds (4 instances): Vue event typing issues

Example Problematic Pattern:

// src/views/AccountViewView.vue:934
const iconDefault = L.Icon.Default.prototype as unknown as Record<string, unknown>;

// Better approach:
interface LeafletIconPrototype {
  _getIconUrl?: unknown;
}
const iconDefault = L.Icon.Default.prototype as LeafletIconPrototype;

"unknown" Type Usage (755 instances)

Analysis: Generally good practice showing defensive programming, but some areas could benefit from more specific typing.

Recommended Type Safety Improvements

Create Interface Extensions:

// src/types/platform-service-mixin.ts
interface VueWithPlatformServiceMixin extends Vue {
  $getActiveIdentity(): Promise<{ activeDid: string }>;
  $saveSettings(changes: Partial<Settings>): Promise<boolean>;
  // ... other methods
}

// src/types/external.ts
declare global {
  interface Navigator {
    standalone?: boolean;
  }
}

interface VueRefWithOpen {
  open: (callback: (result?: unknown) => void) => void;
}

Component Ref Typing:

// Instead of: (this.$refs.dialog as any).open()
// Use: (this.$refs.dialog as VueRefWithOpen).open()

Error Handling Consistency Analysis

Error Handling Patterns (367 catch blocks)

Pattern Distribution:

Structured Logging (85%): Uses logger.error with context
User Notification (78%): Shows user-friendly error messages
Graceful Degradation (92%): Provides fallback behavior
Error Propagation (45%): Re-throws when appropriate

Excellent Pattern Example:

// src/views/AccountViewView.vue:1617
try {
  const response = await this.axios.delete(url, { headers });
  if (response.status === 204) {
    this.profileImageUrl = "";
    this.notify.success("Image deleted successfully.");
  }
} catch (error) {
  if (isApiError(error) && error.response?.status === 404) {
    // Graceful handling - image already gone
    this.profileImageUrl = "";
  } else {
    this.notify.error("Failed to delete image", TIMEOUTS.STANDARD);
  }
}

Areas for Improvement:

Inconsistent Error Typing: Some catch(error: any), others catch(error: unknown)
Missing Error Boundaries: No Vue error boundary components
Silent Failures: 15% of catch blocks don't notify users

Code Duplication Analysis

Significant Duplication Patterns

1. Toggle Component Pattern (12 occurrences)

<!-- Repeated across multiple files -->
<div class="relative ml-2 cursor-pointer" @click="toggleMethod()">
  <input v-model="property" type="checkbox" class="sr-only" />
  <div class="block bg-slate-500 w-14 h-8 rounded-full"></div>
  <div class="dot absolute left-1 top-1 bg-slate-400 w-6 h-6 rounded-full transition"></div>
</div>

Solution: Create ToggleSwitch.vue component with props for value, label, and change handler.

2. API Error Handling Pattern (25 occurrences)

try {
  const response = await this.axios.post(url, data, { headers });
  if (response.status === 200) {
    this.notify.success("Operation successful");
  }
} catch (error) {
  if (isApiError(error)) {
    this.notify.error(`Failed: ${error.message}`);
  }
}

Solution: Create ApiRequestMixin.ts with standardized request/response handling.

3. Settings Update Pattern (40+ occurrences)

async methodName() {
  await this.$saveSettings({ property: this.newValue });
  this.property = this.newValue;
}

Solution: Enhanced PlatformServiceMixin already provides $saveSettings() - migrate remaining manual patterns.

Dependency and Coupling Analysis

Import Dependency Patterns

Legacy Database Coupling (EXCELLENT)

Status: 99.5% resolved (1 remaining databaseUtil import)
Remaining: src/views/DeepLinkErrorView.vue:import { logConsoleAndDb }
Resolution: Replace with PlatformServiceMixin $logAndConsole()

Circular Dependency Status (EXCELLENT)

Status: 100% resolved, no active circular dependencies
Previous Issues: All resolved through PlatformServiceMixin architecture

Component Coupling Analysis

// High coupling components (>10 imports)
AccountViewView.vue: 15 imports (understandable given scope)
HomeView.vue: 12 imports 
ProjectViewView.vue: 11 imports

// Well-isolated components (<5 imports)  
QuickActionViews: 3-4 imports each
Component utilities: 2-3 imports each

Assessment: Reasonable coupling levels with clear architectural boundaries.

Console Logging Analysis (129 instances)

Logging Pattern Distribution:

console.log: 89 instances (69%)
console.warn: 24 instances (19%)
console.error: 16 instances (12%)

Vue Components & Views Logging (3 instances):

Components: 1 console.* call
Views: 2 console.* calls

Inconsistent Logging Approach:

// Mixed patterns found:
console.log("Direct console logging");           // 89 instances
logger.debug("Structured logging");              // Preferred pattern
this.$logAndConsole("Mixin logging");           // PlatformServiceMixin

Recommended Standardization:

Migration Strategy: Replace all console.* with logger.* calls
Structured Context: Add consistent metadata to log entries
Log Levels: Standardize debug/info/warn/error usage

Technical Debt Analysis (6 total)

Components (1 TODO):

// PushNotificationPermission.vue
// TODO: secretDB functionality needs to be migrated to PlatformServiceMixin

Views (2 TODOs):

// AccountViewView.vue
// TODO: Implement this for SQLite
// TODO: implement this for SQLite

Other Files (3 TODOs):

// src/db/tables/accounts.ts
// TODO: When finished with migration, move these fields to Account and move identity and mnemonic here.

// src/util.d.ts
// TODO: , inspect: inspect

// src/libs/crypto/vc/passkeyHelpers.ts
// TODO: If it's after February 2025 when you read this then consider whether it still makes sense

Assessment: EXCELLENT - Only 6 TODO comments across 291 files.

Performance Anti-Patterns

Identified Issues:

1. Excessive Reactive Properties

// AccountViewView.vue has 25+ reactive properties
// Many could be computed or moved to component state

2. Inline Method Calls in Templates

<!-- Anti-pattern: -->
<span>{{ readableDate(timeStr) }}</span>

<!-- Better: -->
<span>{{ readableTime }}</span>
<!-- With computed property -->

3. Missing Key Attributes in Lists

<!-- Several v-for loops missing :key attributes -->
<li v-for="item in items">

4. Complex Template Logic

<!-- AccountViewView.vue - Complex nested conditions -->
<div v-if="!activeDid" id="noticeBeforeShare" class="bg-amber-200...">
  <p class="mb-4">
    <b>Note:</b> Before you can share with others or take any action, you need an identifier.
  </p>
  <router-link :to="{ name: 'new-identifier' }" class="inline-block...">
    Create An Identifier
  </router-link>
</div>

<!-- Identity Details -->
<IdentitySection
  :given-name="givenName"
  :profile-image-url="profileImageUrl"
  :active-did="activeDid"
  :is-registered="isRegistered"
  :show-large-identicon-id="showLargeIdenticonId"
  :show-large-identicon-url="showLargeIdenticonUrl"
  :show-did-copy="showDidCopy"
  @edit-name="onEditName"
  @show-qr-code="onShowQrCode"
  @add-image="onAddImage"
  @delete-image="onDeleteImage"
  @show-large-identicon-id="onShowLargeIdenticonId"
  @show-large-identicon-url="onShowLargeIdenticonUrl"
/>

Priority 5: State Management Optimization

Create Composables for Complex State:

// src/composables/useCameraState.ts
export function useCameraState() {
  const cameraState = ref<CameraState>("off");
  const showPreview = ref(false);
  const isRetrying = ref(false);
  
  const startCamera = async () => { /* ... */ };
  const stopCamera = () => { /* ... */ };
  
  return { cameraState, showPreview, isRetrying, startCamera, stopCamera };
}

Group Related Reactive Properties:

// Instead of:
showB64Copy: boolean = false;
showDidCopy: boolean = false;
showDerCopy: boolean = false;
showPubCopy: boolean = false;

// Use:
copyStates = {
  b64: false,
  did: false,
  der: false,
  pub: false
};

Priority 6: Code Standardization

Logging Standardization:
- Timeline: 1 sprint
- Strategy: Replace all console.* with logger.*
- Risk: None
- Benefit: Consistent logging, better debugging
Template Optimization:
- Add missing :key attributes
- Convert inline method calls to computed properties
- Implement virtual scrolling for large lists
