docs: update build pattern conversion plan with consistent naming and mode handling

- Change build:* naming from hyphen to colon (build:web-dev → build:web:dev)
- Add missing build:web:test and build:web:prod scripts
- Update build:electron:dev to include electron startup (build + start)
- Remove hardcoded --mode electron to allow proper mode override
- Add comprehensive mode override behavior documentation
- Fix mode conflicts between hardcoded and passed --mode arguments

The plan now properly supports:
- Development builds with default --mode development
- Testing builds with explicit --mode test override
- Production builds with explicit --mode production override
- Consistent naming across all platforms (web, capacitor, electron)

# Cursor Markdown Ruleset for TimeSafari Documentation
## Overview
This ruleset enforces consistent markdown formatting standards across all project
documentation, ensuring readability, maintainability, and compliance with
markdownlint best practices.
## General Formatting Standards
### Line Length
- **Maximum line length**: 80 characters
- **Exception**: Code blocks (JSON, shell, TypeScript, etc.) - no line length
enforcement
- **Rationale**: Ensures readability across different screen sizes and terminal
widths
### Blank Lines
- **Headings**: Must be surrounded by blank lines above and below
- **Lists**: Must be surrounded by blank lines above and below
- **Code blocks**: Must be surrounded by blank lines above and below
- **Maximum consecutive blank lines**: 1 (no multiple blank lines)
- **File start**: No blank lines at the beginning of the file
- **File end**: Single newline character at the end
### Whitespace
- **No trailing spaces**: Remove all trailing whitespace from lines
- **No tabs**: Use spaces for indentation
- **Consistent indentation**: 2 spaces for list items and nested content
## Heading Standards
### Format
- **Style**: ATX-style headings (`#`, `##`, `###`, etc.)
- **Case**: Title case for general headings
- **Code references**: Use backticks for file names and technical terms
- ✅ `### Current package.json Scripts`
- ❌ `### Current Package.json Scripts`
### Hierarchy
- **H1 (#)**: Document title only
- **H2 (##)**: Major sections
- **H3 (###)**: Subsections
- **H4 (####)**: Sub-subsections
- **H5+**: Avoid deeper nesting
## List Standards
### Unordered Lists
- **Marker**: Use `-` (hyphen) consistently
- **Indentation**: 2 spaces for nested items
- **Blank lines**: Surround lists with blank lines
### Ordered Lists
- **Format**: `1.`, `2.`, `3.` (sequential numbering)
- **Indentation**: 2 spaces for nested items
- **Blank lines**: Surround lists with blank lines
### Task Lists
- **Format**: `- [ ]` for incomplete, `- [x]` for complete
- **Use case**: Project planning, checklists, implementation tracking
## Code Block Standards
### Fenced Code Blocks
- **Syntax**: Triple backticks with language specification
- **Languages**: `json`, `bash`, `typescript`, `javascript`, `yaml`, `markdown`
- **Blank lines**: Must be surrounded by blank lines above and below
- **Line length**: No enforcement within code blocks
### Inline Code
- **Format**: Single backticks for inline code references
- **Use case**: File names, commands, variables, properties
## Special Content Standards
### JSON Examples
```json
{
"property": "value",
"nested": {
"property": "value"
}
}
```
### Shell Commands
```bash
# Command with comment
npm run build:web
# Multi-line command
VITE_GIT_HASH=`git log -1 --pretty=format:%h` \
vite build --config vite.config.web.mts
```
### TypeScript Examples
```typescript
// Function with JSDoc
/**
* Get environment configuration
* @param env - Environment name
* @returns Environment config object
*/
const getEnvironmentConfig = (env: string) => {
switch (env) {
case 'prod':
return { /* production settings */ };
default:
return { /* development settings */ };
}
};
```

# Build Pattern Conversion Plan
**Author**: Matthew Raymer
**Date**: 2025-07-09
**Status**: 🎯 **PLANNING** - Ready for Implementation
## Overview
Convert TimeSafari's build instruction pattern from the current script-based
approach to a new Vite `mode`-based pattern that provides better environment
management and consistency across all build targets.
## Why Vite Mode Instead of NODE_ENV?
### ✅ Vite's Native Mode System
Vite is designed to work with `mode`, which:
- Determines the `.env` file to load (e.g. `.env.production`, `.env.test`, etc.)
- Is passed to `defineConfig(({ mode }) => {...})` in `vite.config.ts`
- Is used to set behavior for dev/prod/test at config level
- Provides better integration with Vite's build system
### 🚫 NODE_ENV Limitations
`NODE_ENV` is legacy from Webpack-era tooling:
- You can't change `NODE_ENV` manually and expect Vite to adapt
- Vite does not map `NODE_ENV` back to `mode`
- It's redundant with `mode` and might conflict with assumptions
- Limited integration with Vite's environment loading system
### Usage Pattern
```bash
# ✅ Correct: Use Vite's mode system
vite build --mode production
vite build --mode development
vite build --mode test
# ⚠️ Only if third-party libraries require NODE_ENV
NODE_ENV=production vite build --mode production
```
### Development vs Build Environments
**Development Environment:**
- **Build with defaults**: `npm run build:*` - Uses `--mode development` by default
- **Purpose**: Development builds for testing and debugging
- **Output**: Bundled files with development optimizations
**Testing/Production Environments:**
- **Build with explicit mode**: `npm run build:* -- --mode test/production`
- **Purpose**: Validate and deploy the bundled application
- **Output**: Optimized, bundled files for specific environment
### Mode Override Behavior
**How `--mode` Override Works:**
```bash
# Base script (no hardcoded mode)
"build:electron": "vite build --config vite.config.electron.mts"
# Development (uses Vite's default: --mode development)
npm run build:electron
# Executes: vite build --config vite.config.electron.mts
# Testing (explicitly overrides with --mode test)
npm run build:electron -- --mode test
# Executes: vite build --config vite.config.electron.mts --mode test
# Production (explicitly overrides with --mode production)
npm run build:electron -- --mode production
# Executes: vite build --config vite.config.electron.mts --mode production
```
**Key Points:**
- Base scripts have **no hardcoded `--mode`** to allow override
- `npm run build:electron` defaults to `--mode development`
- `npm run build:electron -- --mode test` overrides to `--mode test`
- Vite uses the **last `--mode` argument** if multiple are provided
### Capacitor Platform-Specific Commands
Capacitor requires platform-specific sync commands after building:
```bash
# General sync (copies web assets to all platforms)
npm run build:capacitor && npx cap sync
# Platform-specific sync
npm run build:capacitor && npx cap sync android
npm run build:capacitor && npx cap sync ios
# Environment-specific with platform sync
npm run build:capacitor -- --mode production && npx cap sync android
npm run build:capacitor -- --mode development && npx cap sync ios
```
### Electron Platform-Specific Commands
Electron requires platform-specific build commands after the Vite build:
```bash
# General Electron build (Vite build only)
npm run build:electron
# Platform-specific builds
npm run build:electron:windows # Windows executable
npm run build:electron:mac # macOS app bundle
npm run build:electron:linux # Linux executable
# Package-specific builds
npm run build:electron:appimage # Linux AppImage
npm run build:electron:dmg # macOS DMG installer
# Environment-specific builds
npm run build:electron -- --mode development
npm run build:electron -- --mode test
npm run build:electron -- --mode production
# Environment-specific with platform builds
npm run build:electron:windows -- --mode development
npm run build:electron:windows -- --mode test
npm run build:electron:windows -- --mode production
npm run build:electron:mac -- --mode development
npm run build:electron:mac -- --mode test
npm run build:electron:mac -- --mode production
npm run build:electron:linux -- --mode development
npm run build:electron:linux -- --mode test
npm run build:electron:linux -- --mode production
# Environment-specific with package builds
npm run build:electron:appimage -- --mode development
npm run build:electron:appimage -- --mode test
npm run build:electron:appimage -- --mode production
npm run build:electron:dmg -- --mode development
npm run build:electron:dmg -- --mode test
npm run build:electron:dmg -- --mode production
```
## Current State Analysis
### Existing Build Scripts
- **Web**: `build:web` - Uses vite.config.web.mts
- **Capacitor**: `build:capacitor` - Uses vite.config.capacitor.mts
- **Android**: `build:android` - Shell script wrapper
- **iOS**: `build:ios` - Shell script wrapper
- **Electron**: `build:electron` - Uses vite.config.electron.mts
- **Windows**: `build:electron:windows` - Windows executable
- **macOS**: `build:electron:mac` - macOS app bundle
- **Linux**: `build:electron:linux` - Linux executable
- **AppImage**: `build:electron:appimage` - Linux AppImage
- **DMG**: `build:electron:dmg` - macOS DMG installer
### Current `package.json` Scripts
```json
{
"build:capacitor": "VITE_GIT_HASH=`git log -1 --pretty=format:%h` vite build --mode capacitor --config vite.config.capacitor.mts",
"build:web": "VITE_GIT_HASH=`git log -1 --pretty=format:%h` vite build --config vite.config.web.mts",
"build:electron": "VITE_GIT_HASH=`git log -1 --pretty=format:%h` vite build --mode electron --config vite.config.electron.mts"
}
```
## Target Pattern
### New Vite Mode-Based Pattern
```bash
# Development builds (defaults to --mode development)
npm run build:web-dev
npm run build:capacitor-dev
npm run build:electron-dev
# Testing builds (bundle required)
npm run build:web -- --mode test
npm run build:capacitor -- --mode test && npx cap sync
npm run build:electron -- --mode test
# Production builds (bundle required)
npm run build:web -- --mode production
npm run build:capacitor -- --mode production && npx cap sync
npm run build:electron -- --mode production
# Docker builds
npm run build:web-docker -- --mode test
npm run build:web-docker -- --mode production
# Capacitor platform-specific builds
npm run build:capacitor:android -- --mode test
npm run build:capacitor:android -- --mode production
npm run build:capacitor:ios -- --mode test
npm run build:capacitor:ios -- --mode production
# Electron platform-specific builds
npm run build:electron:windows -- --mode test
npm run build:electron:windows -- --mode production
npm run build:electron:mac -- --mode test
npm run build:electron:mac -- --mode production
npm run build:electron:linux -- --mode test
npm run build:electron:linux -- --mode production
# Electron package-specific builds
npm run build:electron:appimage -- --mode test
npm run build:electron:appimage -- --mode production
npm run build:electron:dmg -- --mode test
npm run build:electron:dmg -- --mode production
```

## Implementation Plan
### Phase 1: Environment Configuration (Day 1)
#### 1.1 Update Vite Configurations
- [ ] **vite.config.web.mts**: Add mode-based configuration
- [ ] **vite.config.capacitor.mts**: Add mode-based configuration
- [ ] **vite.config.electron.mts**: Add mode-based configuration
- [ ] **vite.config.common.mts**: Add environment-specific variables
#### 1.2 Environment Variables Setup
- [ ] Create `.env.development` file for development settings
- [ ] Create `.env.test` file for testing settings
- [ ] Create `.env.production` file for production settings
- [ ] Update `.env.example` with new pattern
#### 1.3 Environment Detection Logic
```typescript
// vite.config.common.mts
export default defineConfig(({ mode }) => {
const getEnvironmentConfig = (mode: string) => {
switch (mode) {
case 'production':
return { /* production settings */ };
case 'test':
return { /* testing settings */ };
default:
return { /* development settings */ };
}
};
return {
define: {
__DEV__: mode === 'development',
__TEST__: mode === 'test',
__PROD__: mode === 'production'
},
// ... other config
};
});
```

## Why Lazy Loading Matters
### Performance Benefits
- **Faster Initial Load**: Only load code needed for the current view
- **Reduced Bundle Size**: Split large applications into smaller chunks
- **Better Caching**: Independent chunks can be cached separately
- **Improved User Experience**: Progressive loading with loading states
### When to Use Lazy Loading
✅ **Good Candidates for Lazy Loading:**
- Heavy components (data processing, 3D rendering)
- Feature-specific components (QR scanner, file uploader)
- Route-based components
- Large third-party libraries (ThreeJS, Chart.js)
- Components with conditional rendering
❌ **Avoid Lazy Loading:**
- Core UI components used everywhere
- Small utility components
- Components needed for initial render
- Components with frequent usage patterns
## Vite Configuration for Optimal Code Splitting
### Enhanced Build Configuration
```typescript
// vite.config.optimized.mts
export async function createOptimizedBuildConfig(mode: string): Promise<UserConfig> {
return {
build: {
rollupOptions: {
output: {
// Enhanced manual chunks for better code splitting
manualChunks: {
// Vendor chunks for better caching
'vue-vendor': ['vue', 'vue-router', 'pinia'],
'ui-vendor': ['@fortawesome/fontawesome-svg-core', '@fortawesome/vue-fontawesome'],
'crypto-vendor': ['@ethersproject/wallet', '@ethersproject/hdnode'],
'sql-vendor': ['@jlongster/sql.js', 'absurd-sql', 'dexie'],
'qr-vendor': ['qrcode', 'jsqr', 'vue-qrcode-reader'],
'three-vendor': ['three', '@tweenjs/tween.js'],
'utils-vendor': ['luxon', 'ramda', 'zod', 'axios'],
// Platform-specific chunks
...(isCapacitor && {
'capacitor-vendor': ['@capacitor/core', '@capacitor/app']
})
}
}
}
}
};
}
```
### Key Configuration Features
1. **Manual Chunks**: Group related dependencies for better caching
2. **Platform-Specific Chunks**: Separate native and web dependencies
3. **Vendor Separation**: Keep third-party libraries separate from app code
4. **Dynamic Imports**: Enable automatic code splitting for dynamic imports
## Lazy Loading Patterns
### 1. Component-Level Lazy Loading
#### Basic Pattern with defineAsyncComponent
```typescript
import { Component, Vue } from 'vue-facing-decorator';
import { defineAsyncComponent } from 'vue';
@Component({
name: 'LazyLoadingExample',
components: {
LazyHeavyComponent: defineAsyncComponent({
loader: () => import('./sub-components/HeavyComponent.vue'),
loadingComponent: {
template: '<div class="loading">Loading...</div>'
},
errorComponent: {
template: '<div class="error">Failed to load</div>'
},
delay: 200,
timeout: 10000
})
}
})
export default class LazyLoadingExample extends Vue {
// Component logic
}
```
#### Advanced Pattern with Suspense
```vue
<template>
<Suspense>
<template #default>
<LazyHeavyComponent v-if="showComponent" />
</template>
<template #fallback>
<div class="loading-fallback">
<div class="spinner"></div>
<p>Loading component...</p>
</div>
</template>
</Suspense>
</template>
```
### 2. Conditional Loading
```typescript
@Component({
name: 'ConditionalLazyLoading'
})
export default class ConditionalLazyLoading extends Vue {
showHeavyComponent = false;
showQRScanner = false;
// Lazy load based on user interaction
async toggleHeavyComponent(): Promise<void> {
this.showHeavyComponent = !this.showHeavyComponent;
if (this.showHeavyComponent) {
// Preload component for better UX
await this.preloadComponent(() => import('./HeavyComponent.vue'));
}
}
private async preloadComponent(loader: () => Promise<any>): Promise<void> {
try {
await loader();
} catch (error) {
console.warn('Preload failed:', error);
}
}
}
```
### 3. Library-Level Lazy Loading
```typescript
@Component({
name: 'LibraryLazyLoading'
})
export default class LibraryLazyLoading extends Vue {
private threeJS: any = null;
async loadThreeJS(): Promise<void> {
if (!this.threeJS) {
// Lazy load ThreeJS only when needed
this.threeJS = await import('three');
console.log('ThreeJS loaded successfully');
}
}
async initialize3DScene(): Promise<void> {
await this.loadThreeJS();
// Use ThreeJS after loading
const scene = new this.threeJS.Scene();
// ... rest of 3D setup
}
}
```
## Component-Level Lazy Loading
### Heavy Data Processing Component
```typescript
// HeavyComponent.vue
@Component({
name: 'HeavyComponent'
})
export default class HeavyComponent extends Vue {
@Prop({ required: true }) readonly data!: any;
async processData(): Promise<void> {
// Process data in batches to avoid blocking UI
const batchSize = 10;
const items = this.data.items;
for (let i = 0; i < items.length; i += batchSize) {
const batch = items.slice(i, i + batchSize);
await this.processBatch(batch);
// Allow UI to update
await this.$nextTick();
await new Promise(resolve => setTimeout(resolve, 10));
}
}
}
```
### Camera-Dependent Component
```typescript
// QRScannerComponent.vue
@Component({
name: 'QRScannerComponent'
})
export default class QRScannerComponent extends Vue {
async mounted(): Promise<void> {
// Initialize camera only when component is mounted
await this.initializeCamera();
}
async initializeCamera(): Promise<void> {
try {
const devices = await navigator.mediaDevices.enumerateDevices();
this.cameras = devices.filter(device => device.kind === 'videoinput');
this.hasCamera = this.cameras.length > 0;
} catch (error) {
console.error('Camera initialization failed:', error);
this.hasCamera = false;
}
}
}
```
## Route-Level Lazy Loading
### Vue Router Configuration
```typescript
// router/index.ts
import { createRouter, createWebHistory } from 'vue-router';
const routes = [
{
path: '/',
name: 'Home',
component: () => import('@/views/HomeView.vue')
},
{
path: '/heavy-feature',
name: 'HeavyFeature',
component: () => import('@/views/HeavyFeatureView.vue'),
// Preload on hover for better UX
beforeEnter: (to, from, next) => {
if (from.name) {
// Preload component when navigating from another route
import('@/views/HeavyFeatureView.vue');
}
next();
}
}
];
export default createRouter({
history: createWebHistory(),
routes
});
```
### Route Guards with Lazy Loading
```typescript
// router/guards.ts
export async function lazyLoadGuard(to: any, from: any, next: any): Promise<void> {
if (to.meta.requiresHeavyFeature) {
try {
// Preload heavy feature before navigation
await import('@/components/HeavyFeature.vue');
next();
} catch (error) {
console.error('Failed to load heavy feature:', error);
next('/error');
}
} else {
next();
}
}
```
## Library-Level Lazy Loading
### Dynamic Library Loading
```typescript
@Component({
name: 'DynamicLibraryLoader'
})
export default class DynamicLibraryLoader extends Vue {
private libraries: Map<string, any> = new Map();
async loadLibrary(name: string): Promise<any> {
if (this.libraries.has(name)) {
return this.libraries.get(name);
}
let library: any;
switch (name) {
case 'three':
library = await import('three');
break;
case 'chart':
library = await import('chart.js');
break;
case 'qr':
library = await import('jsqr');
break;
default:
throw new Error(`Unknown library: ${name}`);
}
this.libraries.set(name, library);
return library;
}
}
```
### Conditional Library Loading
```typescript
@Component({
name: 'ConditionalLibraryLoader'
})
export default class ConditionalLibraryLoader extends Vue {
async loadPlatformSpecificLibrary(): Promise<void> {
if (process.env.VITE_PLATFORM === 'capacitor') {
// Load Capacitor-specific libraries
await import('@capacitor/camera');
await import('@capacitor/filesystem');
} else {
// Load web-specific libraries
await import('file-saver');
await import('jszip');
}
}
}
```
## Performance Monitoring
### Bundle Analysis
```bash
# Analyze bundle size
npm run build
npx vite-bundle-analyzer dist
# Monitor chunk sizes
npx vite-bundle-analyzer dist --mode=treemap
```
### Runtime Performance Monitoring
```typescript
@Component({
name: 'PerformanceMonitor'
})
export default class PerformanceMonitor extends Vue {
private performanceMetrics = {
componentLoadTime: 0,
renderTime: 0,
memoryUsage: 0
};
private measureComponentLoad(componentName: string): void {
const startTime = performance.now();
return () => {
const loadTime = performance.now() - startTime;
this.performanceMetrics.componentLoadTime = loadTime;
console.log(`${componentName} loaded in ${loadTime.toFixed(2)}ms`);
// Send to analytics
this.trackPerformance(componentName, loadTime);
};
}
private trackPerformance(component: string, loadTime: number): void {
// Send to analytics service
if (window.gtag) {
window.gtag('event', 'component_load', {
component_name: component,
load_time: loadTime
});
}
}
}
```
## Best Practices
### 1. Loading States
Always provide meaningful loading states:
```vue
<template>
<Suspense>
<template #default>
<LazyComponent />
</template>
<template #fallback>
<div class="loading-state">
<div class="spinner"></div>
<p>Loading {{ componentName }}...</p>
<p class="loading-tip">{{ loadingTip }}</p>
</div>
</template>
</Suspense>
</template>
```
### 2. Error Handling
Implement comprehensive error handling:
```typescript
const LazyComponent = defineAsyncComponent({
loader: () => import('./HeavyComponent.vue'),
errorComponent: {
template: `
<div class="error-state">
<h3>Failed to load component</h3>
<p>{{ error.message }}</p>
<button @click="retry">Retry</button>
</div>
`,
props: ['error'],
methods: {
retry() {
this.$emit('retry');
}
}
},
onError(error, retry, fail, attempts) {
if (attempts <= 3) {
console.warn(`Retrying component load (attempt ${attempts})`);
retry();
} else {
console.error('Component failed to load after 3 attempts');
fail();
}
}
});
```
### 3. Preloading Strategy
Implement intelligent preloading:
```typescript
@Component({
name: 'SmartPreloader'
})
export default class SmartPreloader extends Vue {
private preloadQueue: Array<() => Promise<any>> = [];
private isPreloading = false;
// Preload based on user behavior
onUserHover(componentLoader: () => Promise<any>): void {
this.preloadQueue.push(componentLoader);
this.processPreloadQueue();
}
private async processPreloadQueue(): Promise<void> {
if (this.isPreloading || this.preloadQueue.length === 0) return;
this.isPreloading = true;
while (this.preloadQueue.length > 0) {
const loader = this.preloadQueue.shift();
if (loader) {
try {
await loader();
} catch (error) {
console.warn('Preload failed:', error);
}
}
// Small delay between preloads
await new Promise(resolve => setTimeout(resolve, 100));
}
this.isPreloading = false;
}
}
```
### 4. Bundle Optimization
Optimize bundle splitting:
```typescript
// vite.config.ts
export default defineConfig({
build: {
rollupOptions: {
output: {
manualChunks: (id) => {
// Group by feature
if (id.includes('qr')) return 'qr-feature';
if (id.includes('three')) return '3d-feature';
if (id.includes('chart')) return 'chart-feature';
// Group by vendor
if (id.includes('node_modules')) {
if (id.includes('vue')) return 'vue-vendor';
if (id.includes('lodash')) return 'utils-vendor';
return 'vendor';
}
}
}
}
}
});
```
## Common Pitfalls
### 1. Over-Lazy Loading
❌ **Don't lazy load everything:**
```typescript
// Bad: Lazy loading small components
const SmallButton = defineAsyncComponent(() => import('./SmallButton.vue'));
```
✅ **Do lazy load strategically:**
```typescript
// Good: Lazy load heavy components only
const HeavyDataProcessor = defineAsyncComponent(() => import('./HeavyDataProcessor.vue'));
```
### 2. Missing Loading States
❌ **Don't leave users hanging:**
```vue
<template>
<LazyComponent v-if="show" />
</template>
```
✅ **Do provide loading feedback:**
```vue
<template>
<Suspense>
<template #default>
<LazyComponent v-if="show" />
</template>
<template #fallback>
<LoadingSpinner />
</template>
</Suspense>
</template>
```
### 3. Ignoring Error States
❌ **Don't ignore loading failures:**
```typescript
const LazyComponent = defineAsyncComponent(() => import('./Component.vue'));
```
✅ **Do handle errors gracefully:**
```typescript
const LazyComponent = defineAsyncComponent({
loader: () => import('./Component.vue'),
errorComponent: ErrorFallback,
onError: (error, retry, fail) => {
console.error('Component load failed:', error);
// Retry once, then fail
retry();
}
});
```
## Examples
### Complete Lazy Loading Example

1. **`src/components/LazyLoadingExample.vue`** - Main example component
2. **`src/components/sub-components/HeavyComponent.vue`** - Data processing component
3. **`src/components/sub-components/QRScannerComponent.vue`** - Camera-dependent component
4. **`src/components/sub-components/ThreeJSViewer.vue`** - 3D rendering component
5. **`vite.config.optimized.mts`** - Optimized Vite configuration
### Usage Example
```vue
<template>
<div class="app">
<h1>Lazy Loading Demo</h1>
<LazyLoadingExample
:initial-load-heavy="false"
@qr-detected="handleQRCode"
@model-loaded="handleModelLoaded"
/>
</div>
</template>
<script lang="ts">
import { Component, Vue } from 'vue-facing-decorator';
import LazyLoadingExample from '@/components/LazyLoadingExample.vue';
@Component({
name: 'App',
components: {
LazyLoadingExample
}
})
export default class App extends Vue {
handleQRCode(data: string): void {
console.log('QR code detected:', data);
}
handleModelLoaded(info: any): void {
console.log('3D model loaded:', info);
}
}
</script>
```
## Conclusion
Lazy loading with Vue 3 + Vite + `vue-facing-decorator` provides powerful tools for optimizing application performance. By implementing these patterns strategically, you can significantly improve initial load times while maintaining excellent user experience.
Remember to:
- Use lazy loading for heavy components and features
- Provide meaningful loading and error states
- Monitor performance and bundle sizes
- Implement intelligent preloading strategies
- Handle errors gracefully
