||||||
|
|
||||||
|
1. **Code Reviews**: Check ARIA usage in PR reviews
|
||||||
|
2. **Testing**: Include keyboard navigation in manual testing
|
||||||
|
3. **Monitoring**: Run axe scan monthly
|
||||||
|
4. **Updates**: Test new components before merge
|
||||||
|
5. **Training**: Team familiarization with WCAG 2.1 AA

# Performance Optimization Guide
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This guide outlines performance best practices for the K-ArtSell Aegis frontend application.
|
||||||
|
|
||||||
|
## 1. Code Splitting
|
||||||
|
|
||||||
|
### Route-Based Code Splitting
|
||||||
|
|
||||||
|
All pages are lazy-loaded to reduce initial bundle size:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// router.ts
|
||||||
|
import { defineAsyncComponent } from 'vue'
|
||||||
|
|
||||||
|
const ShadowRunQueue = defineAsyncComponent(() =>
|
||||||
|
import('./features/shadow-run/pages/ShadowRunQueue.vue')
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Dynamic Imports
|
||||||
|
|
||||||
|
For large components, use dynamic imports:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
const HeavyComponent = defineAsyncComponent(() =>
|
||||||
|
import('./components/HeavyComponent.vue')
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
## 2. Bundle Analysis
|
||||||
|
|
||||||
|
Check bundle size:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm run build -- --report
|
||||||
|
```
|
||||||
|
|
||||||
|
Current budgets:
|
||||||
|
- Main bundle: < 200KB (gzipped)
|
||||||
|
- Vendor bundle: < 300KB (gzipped)
|
||||||
|
- Per-route chunk: < 50KB (gzipped)
|
||||||
|
|
||||||
|
## 3. Image Optimization
|
||||||
|
|
||||||
|
### Image Sizes
|
||||||
|
|
||||||
|
All images should be optimized before deployment:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Optimize PNG
|
||||||
|
optipng -o2 image.png
|
||||||
|
|
||||||
|
# Optimize JPEG
|
||||||
|
jpegoptim --max=85 image.jpg
|
||||||
|
|
||||||
|
# Use WebP for modern browsers
|
||||||
|
cwebp image.png -o image.webp
|
||||||
|
```
|
||||||
|
|
||||||
|
### Lazy Loading
|
||||||
|
|
||||||
|
Use native lazy loading:
|
||||||
|
|
||||||
|
```html
|
||||||
|
<img src="image.jpg" loading="lazy" alt="Description" />
|
||||||
|
```
|
||||||
|
|
||||||
|
## 4. Caching Strategy
|
||||||
|
|
||||||
|
### Service Worker
|
||||||
|
|
||||||
|
Caching strategy (if enabled):
|
||||||
|
- Static assets: Cache indefinitely
|
||||||
|
- API responses: Network first, fallback to cache
|
||||||
|
- HTML: Network first, always
|
||||||
|
|
||||||
|
### Browser Caching
|
||||||
|
|
||||||
|
Headers set by server:
|
||||||
|
```
|
||||||
|
Cache-Control: max-age=31536000 (1 year) for /assets/*
|
||||||
|
Cache-Control: max-age=3600 (1 hour) for /index.html
|
||||||
|
```
|
||||||
|
|
||||||
|
## 5. Rendering Performance
|
||||||
|
|
||||||
|
### Virtual Scrolling
|
||||||
|
|
||||||
|
For large lists (>100 items), use virtual scrolling:
|
||||||
|
|
||||||
|
```vue
|
||||||
|
<virtual-scroller
|
||||||
|
:items="items"
|
||||||
|
:item-size="50"
|
||||||
|
class="list-container"
|
||||||
|
>
|
||||||
|
<template #default="{ item }">
|
||||||
|
<div>{{ item.name }}</div>
|
||||||
|
</template>
|
||||||
|
</virtual-scroller>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Lighthouse Scores Target
|
||||||
|
|
||||||
|
Current targets (Lighthouse v10):
|
||||||
|
- **Performance**: 90+
|
||||||
|
- **Accessibility**: 95+
|
||||||
|
- **Best Practices**: 90+
|
||||||
|
- **SEO**: 90+
|
||||||
|
- **PWA**: 90+
|
||||||
|
|
||||||
|
## 6. Monitoring
|
||||||
|
|
||||||
|
### Core Web Vitals
|
||||||
|
|
||||||
|
Monitor these key metrics:
|
||||||
|
- **LCP** (Largest Contentful Paint): < 2.5s
|
||||||
|
- **FID** (First Input Delay): < 100ms
|
||||||
|
- **CLS** (Cumulative Layout Shift): < 0.1
|
||||||
|
|
||||||
|
### Performance API
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Custom timing
|
||||||
|
performance.mark('operation-start')
|
||||||
|
// ... do work ...
|
||||||
|
performance.mark('operation-end')
|
||||||
|
performance.measure('operation', 'operation-start', 'operation-end')
|
||||||
|
|
||||||
|
const measure = performance.getEntriesByName('operation')[0]
|
||||||
|
console.log(`Operation took ${measure.duration}ms`)
|
||||||
|
```
|
||||||
|
|
||||||
|
## 7. Network Optimization
|
||||||
|
|
||||||
|
### HTTP/2 Server Push
|
||||||
|
|
||||||
|
Critical assets are pushed by server:
|
||||||
|
- `tokens.css`
|
||||||
|
- `main.js` (critical path)
|
||||||
|
|
||||||
|
### Compression
|
||||||
|
|
||||||
|
All text assets are gzip compressed (75% reduction typical).
|
||||||
|
|
||||||
|
## 8. Development Performance
|
||||||
|
|
||||||
|
### Vite Config
|
||||||
|
|
||||||
|
Current Vite settings for optimal DX:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// vite.config.ts
|
||||||
|
export default {
|
||||||
|
build: {
|
||||||
|
rollupOptions: {
|
||||||
|
output: {
|
||||||
|
manualChunks: {
|
||||||
|
'vendor': ['vue', 'vue-router', '@tanstack/vue-query'],
|
||||||
|
'ui': ['@kbx/ui', 'primevue'],
|
||||||
|
}
|
||||||
|
}
|
||||||
|
},
|
||||||
|
minify: 'terser',
|
||||||
|
target: 'esnext',
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Build Metrics
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Analyze build time
|
||||||
|
npm run build -- --debug-time
|
||||||
|
|
||||||
|
# Expected: < 30s total build time
|
||||||
|
```
|
||||||
|
|
||||||
|
