1.1 前端性能優化
當前性能狀況分析
基於 463 個組件的大型應用,發現以下性能瓶頸:
JavaScript Bundle 分析
bash
# 當前 bundle 大小分析 (估算)
dist/
├── index-[hash].js # ~800KB (主要 chunk)
├── vendor-[hash].js # ~1.2MB (第三方庫)
├── charts-[hash].js # ~300KB (圖表庫)
└── views-[hash].js # ~600KB (頁面組件)
總計: ~2.9MB (未壓縮)具體優化方案
typescript
// 1. 圖表組件懶加載優化
// charts/index.ts
export const LazyAreaChart = defineAsyncComponent({
loader: () => import('./pure/AreaChart.vue'),
loadingComponent: ChartSkeleton,
errorComponent: ChartError,
delay: 200,
timeout: 5000
})
// 2. 路由級別的代碼分割
// router/index.ts
const routes = [
{
path: '/insights',
children: [
{
path: 'executive-health',
component: () => import(
/* webpackChunkName: "insights-executive" */
'@/views/DashboardExecutiveHealth.vue'
)
}
]
}
]
// 3. 第三方庫按需導入
// 替換全量導入
import * as echarts from 'echarts'
// 改為按需導入
import { init, use } from 'echarts/core'
import { LineChart, BarChart } from 'echarts/charts'內存優化策略
typescript
// composables/useListVirtualization.ts
import { useVirtualList } from '@tanstack/vue-virtual'
export const useOptimizedList = <T>(
items: Ref<T[]>,
estimateSize = 50
) => {
const containerRef = ref<HTMLElement>()
const virtualizer = useVirtualList({
count: computed(() => items.value.length),
getScrollElement: () => containerRef.value,
estimateSize: () => estimateSize,
overscan: 10 // 預渲染項目數
})
return {
containerRef,
virtualizer,
visibleItems: computed(() =>
virtualizer.getVirtualItems().map(item => ({
...item,
data: items.value[item.index]
}))
)
}
}1.2 數據加載優化
API 請求優化
typescript
// composables/useOptimizedQuery.ts
import { useQuery, useInfiniteQuery } from '@tanstack/vue-query'
// 智能快取策略
export const useCustomersQuery = (filters: Ref<CustomerFilters>) => {
return useQuery({
queryKey: ['customers', filters],
queryFn: ({ queryKey }) => {
const [_, filters] = queryKey
return customerApi.getFiltered(filters)
},
staleTime: 5 * 60 * 1000, // 5分鐘內認為數據是新鮮的
gcTime: 30 * 60 * 1000, // 30分鐘後清理緩存
refetchOnWindowFocus: false, // 避免頻繁刷新
retry: (failureCount, error) => {
// 智能重試邏輯
if (error.status === 404) return false
return failureCount < 3
}
})
}
// 無限滾動優化
export const useInfiniteCustomers = () => {
return useInfiniteQuery({
queryKey: ['customers', 'infinite'],
queryFn: ({ pageParam = 1 }) =>
customerApi.getPaginated({ page: pageParam, limit: 20 }),
getNextPageParam: (lastPage) =>
lastPage.hasMore ? lastPage.nextPage : undefined,
initialPageParam: 1
})
}圖片與資源優化
typescript
// utils/imageOptimization.ts
export class ImageOptimizer {
private static cache = new Map<string, string>()
static async optimizeAvatar(url: string, size: number = 40): Promise<string> {
const cacheKey = `${url}-${size}`
if (this.cache.has(cacheKey)) {
return this.cache.get(cacheKey)!
}
// 使用 Canvas API 或 URL 參數優化圖片
const optimizedUrl = `${url}?w=${size}&h=${size}&f=webp&q=80`
this.cache.set(cacheKey, optimizedUrl)
return optimizedUrl
}
static preloadCriticalImages(urls: string[]) {
urls.forEach(url => {
const link = document.createElement('link')
link.rel = 'preload'
link.as = 'image'
link.href = url
document.head.appendChild(link)
})
}
}🧪 測試策略完善
2.1 測試覆蓋率提升計劃
當前測試狀況詳析
bash
# 現有測試文件統計
tests/unit/composables/ # 11個測試文件 ✅ 覆蓋完整
tests/unit/components/ # 僅部分組件有測試 ❌
tests/integration/ # 整合測試基礎架構 ⚠️ 需要擴充
e2e/ # 1個 E2E 測試 ❌ 嚴重不足優先測試清單
高優先級 (業務關鍵組件)
typescript
// 1. 認證相關組件測試
describe('LoginForm', () => {
it('should validate email format', () => {
// 測試郵件格式驗證
})
it('should handle login errors', () => {
// 測試登入錯誤處理
})
it('should redirect after successful login', () => {
// 測試登入後重導向
})
})
// 2. 權限系統測試
describe('PermissionMatrix', () => {
it('should display user permissions correctly', () => {
// 測試權限顯示
})
it('should handle permission changes', () => {
// 測試權限變更
})
})
// 3. 數據表格測試
describe('DataTable', () => {
it('should render large datasets efficiently', () => {
// 測試大數據集渲染
})
it('should handle sorting and filtering', () => {
// 測試排序篩選功能
})
})中優先級 (用戶體驗組件)
- 圖表組件 (charts/**)
- 通知組件 (notify/**)
- 表單組件 (common/forms/**)
E2E 測試場景規劃
typescript
// e2e/critical-flows.spec.ts
describe('Critical User Flows', () => {
test('Complete customer management flow', async ({ page }) => {
// 1. 登入系統
await page.goto('/login')
await page.fill('[data-testid=email]', 'admin@test.com')
await page.fill('[data-testid=password]', 'password')
await page.click('[data-testid=login-button]')
// 2. 導航到客戶頁面
await page.click('[data-testid=nav-customers]')
await expect(page).toHaveURL('/customers')
// 3. 新增客戶
await page.click('[data-testid=add-customer]')
await page.fill('[data-testid=customer-name]', 'Test Customer')
await page.fill('[data-testid=customer-email]', 'test@example.com')
await page.click('[data-testid=save-customer]')
// 4. 驗證客戶已新增
await expect(page.locator('[data-testid=customer-list]')).toContainText('Test Customer')
})
test('Order creation and payment flow', async ({ page }) => {
// 完整訂單創建流程測試
})
test('Permission management flow', async ({ page }) => {
// 權限管理流程測試
})
})2.2 自動化測試流程

path: test-results/API 服務與錯誤處理強化
3.1 統一錯誤處理系統
現有 API 服務優化
基於現有的 ServiceFactory 模式,添加統一錯誤處理:
typescript
// api/services/base/ErrorHandler.ts
export interface ApiError {
code: string
message: string
status: number
timestamp: string
path: string
details?: Record<string, unknown>
}
export class ApiErrorHandler {
private static errorMessages: Record<string, string> = {
'NETWORK_ERROR': '網路連線異常,請檢查網路設定',
'TIMEOUT_ERROR': '請求逾時,請稍後重試',
'AUTH_ERROR': '認證失敗,請重新登入',
'PERMISSION_ERROR': '權限不足,無法執行此操作',
'VALIDATION_ERROR': '資料格式不正確,請檢查輸入',
'SERVER_ERROR': '伺服器暫時無法回應,請稍後重試'
}
static classify(error: any): ApiError {
const now = new Date().toISOString()
// 網路錯誤
if (!error.response) {
return {
code: 'NETWORK_ERROR',
message: this.errorMessages.NETWORK_ERROR,
status: 0,
timestamp: now,
path: error.config?.url || 'unknown'
}
}
// HTTP 錯誤
const status = error.response.status
const path = error.config?.url || 'unknown'
if (status === 401) {
return {
code: 'AUTH_ERROR',
message: this.errorMessages.AUTH_ERROR,
status,
timestamp: now,
path
}
}
if (status === 403) {
return {
code: 'PERMISSION_ERROR',
message: this.errorMessages.PERMISSION_ERROR,
status,
timestamp: now,
path
}
}
if (status >= 400 && status < 500) {
return {
code: 'VALIDATION_ERROR',
message: error.response.data?.message || this.errorMessages.VALIDATION_ERROR,
status,
timestamp: now,
path,
details: error.response.data
}
}
return {
code: 'SERVER_ERROR',
message: this.errorMessages.SERVER_ERROR,
status,
timestamp: now,
path
}
}
static async handle(error: any): Promise<ApiError> {
const apiError = this.classify(error)
// 記錄錯誤
console.error('API Error:', apiError)
// 特殊處理
if (apiError.code === 'AUTH_ERROR') {
const authStore = useAuthStore()
await authStore.signOut()
window.location.href = '/login'
}
// 顯示用戶通知
const toast = useToast()
toast.error(apiError.message)
return apiError
}
}重試機制實現
typescript
// api/services/base/RetryHandler.ts
export class RetryHandler {
private static readonly DEFAULT_RETRIES = 3
private static readonly RETRY_DELAY = 1000
static async withRetry<T>(
operation: () => Promise<T>,
maxRetries = this.DEFAULT_RETRIES,
delayMs = this.RETRY_DELAY
): Promise<T> {
let lastError: any
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
return await operation()
} catch (error: any) {
lastError = error
// 不需要重試的錯誤類型
if (error.response?.status >= 400 && error.response?.status < 500) {
throw error
}
if (attempt < maxRetries) {
// 指數退避重試
const delay = delayMs * Math.pow(2, attempt - 1)
await this.sleep(delay)
console.warn(`API call failed, retrying... (${attempt}/${maxRetries})`)
}
}
}
throw lastError
}
private static sleep(ms: number): Promise<void> {
return new Promise(resolve => setTimeout(resolve, ms))
}
}3.2 API 性能監控
請求時間監控
typescript
// api/services/base/PerformanceMonitor.ts
export class ApiPerformanceMonitor {
private static metrics: Map<string, number[]> = new Map()
static startTimer(endpoint: string): string {
const timerId = `${endpoint}-${Date.now()}`
performance.mark(`api-start-${timerId}`)
return timerId
}
static endTimer(timerId: string, endpoint: string): number {
performance.mark(`api-end-${timerId}`)
const measureName = `api-duration-${timerId}`
performance.measure(measureName, `api-start-${timerId}`, `api-end-${timerId}`)
const measure = performance.getEntriesByName(measureName)[0]
const duration = measure.duration
// 記錄性能數據
if (!this.metrics.has(endpoint)) {
this.metrics.set(endpoint, [])
}
this.metrics.get(endpoint)!.push(duration)
// 性能警告
if (duration > 2000) {
console.warn(`Slow API call: ${endpoint} took ${duration.toFixed(2)}ms`)
}
// 清理性能標記
performance.clearMarks(`api-start-${timerId}`)
performance.clearMarks(`api-end-${timerId}`)
performance.clearMeasures(measureName)
return duration
}
static getMetrics(): Record<string, { avg: number; min: number; max: number; count: number }> {
const result: Record<string, any> = {}
this.metrics.forEach((durations, endpoint) => {
result[endpoint] = {
avg: durations.reduce((a, b) => a + b, 0) / durations.length,
min: Math.min(...durations),
max: Math.max(...durations),
count: durations.length
}
})
return result
}
}監控與分析系統
4.1 前端監控實現
用戶行為追蹤
typescript
// utils/analytics.ts
export class AnalyticsTracker {
private static events: AnalyticsEvent[] = []
static track(event: AnalyticsEvent) {
this.events.push({
...event,
timestamp: Date.now(),
sessionId: this.getSessionId(),
userId: this.getUserId()
})
// 批量發送到後端
if (this.events.length >= 10) {
this.flush()
}
}
static trackPageView(path: string) {
this.track({
type: 'page_view',
properties: { path }
})
}
static trackUserAction(action: string, target: string, properties?: Record<string, any>) {
this.track({
type: 'user_action',
properties: { action, target, ...properties }
})
}
static trackError(error: Error, context?: string) {
this.track({
type: 'error',
properties: {
message: error.message,
stack: error.stack,
context
}
})
}
private static async flush() {
if (this.events.length === 0) return
try {
await fetch('/api/analytics', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ events: this.events })
})
this.events = []
} catch (error) {
console.error('Failed to send analytics:', error)
}
}
}性能指標收集
typescript
// utils/performanceMetrics.ts
export class PerformanceMetrics {
static collectWebVitals() {
// Core Web Vitals
import('web-vitals').then(({ getCLS, getFID, getFCP, getLCP, getTTFB }) => {
getCLS(this.sendMetric)
getFID(this.sendMetric)
getFCP(this.sendMetric)
getLCP(this.sendMetric)
getTTFB(this.sendMetric)
})
}
static collectCustomMetrics() {
// 自定義性能指標
const navigationStart = performance.timeOrigin
const domContentLoaded = performance.getEntriesByName('DOMContentLoaded')[0]?.startTime
const loadComplete = performance.getEntriesByName('load')[0]?.startTime
this.sendMetric({
name: 'dom_content_loaded',
value: domContentLoaded || 0,
id: 'custom-dcl'
})
this.sendMetric({
name: 'load_complete',
value: loadComplete || 0,
id: 'custom-load'
})
}
private static sendMetric(metric: any) {
// 發送性能指標到監控系統
fetch('/api/metrics', {
method: 'POST',
body: JSON.stringify(metric),
headers: { 'Content-Type': 'application/json' }
}).catch(console.error)
}
}開發流程與工具鏈優化
