 # 代码编写规范
 本文档定义了 Testing Tools 浏览器扩展项目的编码规范和最佳实践。所有代码贡献者应遵循这些规范以保持代码库的一致性和可维护性。
 ## 1. TypeScript 规范
 ### 1.1 类型定义：`interface` vs `type`
 - **`interface`**：用于组件 Props、对象结构、Context 类型等可扩展结构
 - **`type`**：用于联合类型、工具类型、不可扩展的类型别名
 ```typescript
 // ✅ interface — 组件 Props / 对象结构
 export interface GlobalSnackbarProps {
  message: string;
  open: boolean;
  onClose: () => void;
  severity?: SnackbarSeverity;
 }
 // ✅ interface — 继承 HTML 属性
 interface LiveClockProps extends React.HTMLAttributes<HTMLDivElement> {
  unit: UnitType;
  onUseNow: (val: number) => void;
 }
 // ✅ type — 联合类型
 export type ThemeMode = 'light' | 'dark' | 'system';
 export type PageType = 'dashboard' | 'timestamp' | 'storageCleaner' | ...;
 // ✅ type — 工具类型
 export type ResolvedThemeMode = 'light' | 'dark';
 ```
 ### 1.2 泛型使用
 广泛使用泛型约束，结合 `extends` 进行类型守卫：
 ```typescript
 // ✅ 泛型 + extends 约束
 export interface SwitchOption<T extends string | number = string> {
  value: T;
  label: React.ReactNode;
 }
 // ✅ 泛型 + StorageSchema 键约束
 async get<K extends keyof StorageSchema>(
  key: K,
  defaultValue?: StorageSchema[K],
 ): Promise<StorageSchema[K] | undefined> { ... }
 // ✅ 泛型 Hook
 export const useStorageState = <K extends keyof StorageSchema>(
  key: K,
  defaultValue: StorageSchema[K],
  validator?: (val: unknown) => val is StorageSchema[K],
 ) => { ... }
 ```
 ### 1.3 类型守卫
 优先使用类型守卫函数（`val is Type` 谓词），避免 `as` 强转：
 ```typescript
 // ✅ 类型守卫谓词函数
 const isValidMode = (v: unknown): v is ThemeMode => VALID_MODES.includes(v as ThemeMode);
 const isValidPage = (page: unknown): page is PageType => {
  return typeof page === 'string' && (getAllFeatureKeys() as string[]).includes(page);
 };
 // ✅ 安全的 as 断言，仅在类型守卫验证后使用
 export function isSupportedImageType(mimeType: string): boolean {
  return (SUPPORTED_IMAGE_TYPES as readonly string[]).includes(mimeType);
 }
 ```
 ### 1.4 导出模式
 | 场景        | 导出方式                                         | 示例                              |
 | ----------- | ------------------------------------------------ | --------------------------------- |
 | 页面组件    | `export default function ComponentName()`        | `src/pages/Timestamp/index.tsx`   |
 | 业务组件    | `const X = React.memo(...)` + `export default X` | `LiveClock.tsx`, `ResultView.tsx` |
 | UI 原子组件 | `React.forwardRef(...)` + `export { X }`         | `src/components/ui/button.tsx`    |
 | 工具函数    | `export function xxx()`                          | `src/utils/clipboard.ts`          |
 | 自定义 Hook | `export function useXxx()`                       | `src/utils/useStorageState.ts`    |
 | 类型/接口   | `export interface` / `export type`               | `src/types/storage.d.ts`          |
 ```typescript
 // ✅ 页面组件 — default export
 export default function Index() { ... }
 // ✅ 需要 memo 的组件 — 箭头函数 + React.memo + displayName
 const LiveClock = React.memo(({ ... }: LiveClockProps) => { ... });
 LiveClock.displayName = 'LiveClock';
 export default LiveClock;
 // ✅ UI 组件 — forwardRef + 命名导出
 const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(...);
 Button.displayName = 'Button';
 export { Button, buttonVariants };
 ```
 ---
 ## 2. React 组件规范
 ### 2.1 组件定义方式
 - **标准组件**：使用 `function` 声明
 - **需要 memo 的组件**：使用箭头函数 + `React.memo`
 - **需要 ref 的组件**：使用 `React.forwardRef`
 - **错误边界**：使用 Class 组件（React 要求）
 ```typescript
 // ✅ 标准页面组件
 export default function Index() { ... }
 // ✅ 需要 memo 的组件
 const LiveClock = React.memo(({ unit, onUseNow, className, ...props }: LiveClockProps) => {
  ...
 });
 LiveClock.displayName = 'LiveClock';
 export default LiveClock;
 // ✅ 需要 ref 的组件
 const TextInputArea = forwardRef<HTMLTextAreaElement, TextInputAreaProps>((props, ref) => {
  ...
 });
 TextInputArea.displayName = 'TextInputArea';
 export default TextInputArea;
 // ✅ Class 组件（仅用于 ErrorBoundary）
 export class ErrorBoundary extends Component<Props, State> { ... }
 ```
 ### 2.2 Props 模式
 - 使用 `interface` 定义 Props
 - 继承 `React.HTMLAttributes` 以支持原生属性透传
 - 使用 `Omit` 排除冲突属性
 - 解构 `className` 和 `...rest props`
 ```typescript
 // ✅ 继承 HTML 属性 + className 透传
 interface ResultViewProps extends React.HTMLAttributes<HTMLDivElement> {
  result: string;
  mode: 'ts2dt' | 'dt2ts';
  unit: UnitType;
  zone: string;
  showEmptyPlaceholder?: boolean;
 }
 // 使用时解构 className 和 rest props
 const ResultView = React.memo(({
  result, mode, unit, zone,
  showEmptyPlaceholder = false,
  className, ...props
 }: ResultViewProps) => {
  return <div className={cn('flex flex-col w-full', className)} {...props}>...</div>;
 });
 // ✅ Omit 排除冲突属性
 export interface TextInputAreaProps extends Omit<
  React.TextareaHTMLAttributes<HTMLTextAreaElement>, 'onChange'
 > { ... }
 ```
 ### 2.3 状态管理
 - **本地状态**：`useState` + 惰性初始化
 - **衍生状态**：`useMemo` 响应式计算管线
 - **持久化状态**：Chrome Storage + `localStorage` 快照
 - **全局状态**：React Context
 ```typescript
 // ✅ useState + 惰性初始化
 const [input, setInput] = useState(() => String(Date.now()));
 // ✅ useMemo 响应式计算管线（零延迟，无需手动 convert 按钮）
 const conversionPipeline = useMemo(() => {
  const rawInput = input.trim();
  if (!rawInput) return { result: '', error: '' };
  // ... 自动计算结果
 }, [input, mode, unit, zone, t]);
 // ✅ Chrome Storage 持久化状态
 export const useStorageState = <K extends keyof StorageSchema>(
  key: K, defaultValue: StorageSchema[K], validator?: ...
 ) => { ... }
 ```
 ### 2.4 副作用模式
 - **取消标志**：防止异步竞态
 - **ref 回调指针**：保持回调最新避免依赖膨胀
 - **事件监听 cleanup**：始终在 cleanup 中移除监听器
 - **定时器 cleanup**：始终在 cleanup 中清除定时器
 ```typescript
 // ✅ 取消标志模式 — 防止异步竞态
 useEffect(() => {
  let cancelled = false;
  storageUtil.get(THEME_MODE_KEY, 'system').then((saved) => {
    if (cancelled) return;
    if (isValidMode(saved)) { ... }
  });
  return () => { cancelled = true; };
 }, [updateResolved]);
 // ✅ ref 回调指针 — 保持回调最新避免依赖膨胀
 const onUseNowRef = useRef(onUseNow);
 useEffect(() => { onUseNowRef.current = onUseNow; }, [onUseNow]);
 // ✅ setInterval + cleanup
 useEffect(() => {
  const tickId = setInterval(tick, 200);
  return () => clearInterval(tickId);
 }, [unit]);
 // ✅ 事件监听 cleanup
 useEffect(() => {
  const handleClickOutside = (event: MouseEvent) => { ... };
  document.addEventListener('mousedown', handleClickOutside);
  return () => document.removeEventListener('mousedown', handleClickOutside);
 }, []);
 ```
 ### 2.5 `memo` / `useCallback` / `useMemo` 使用
 | 场景                               | 使用方式      |
 | ---------------------------------- | ------------- |
 | 高频渲染组件（列表子项、实时时钟） | `React.memo`  |
 | 事件处理函数、回调引用             | `useCallback` |
 | 响应式计算管线、衍生数据           | `useMemo`     |
 | 避免重复创建对象/集合              | `useMemo`     |
 ```typescript
 // ✅ React.memo — 高频更新组件
 const LiveClock = React.memo(({ ... }) => { ... });
 const ResultView = React.memo(({ ... }) => { ... });
 // ✅ useCallback — 事件处理
 const handleUseNow = useCallback((now: number) => {
  if (mode === 'ts2dt') {
    setInput(String(unit === 'ms' ? now : Math.floor(now / 1000)));
  } else {
    setInput(dayjs(now).tz(zone).format(DATE_FORMAT));
  }
 }, [mode, unit, zone]);
 // ✅ useMemo — 避免重复创建集合
 const visibleSet = useMemo(() => new Set<string>(visiblePages), [visiblePages]);
 ```
 ---
 ## 3. 导入规范
 ### 3.1 导入顺序
 按来源分组，顺序如下：
 1. React 核心
 2. 第三方库（图标、UI 库等）
 3. 业务 Provider / Context
 4. 配置 / 存储
 5. i18n
 6. 本地页面组件
 7. UI 组件
 8. 工具函数 / Hook
 9. 类型
 10. 常量
 ```typescript
 // 1. React 核心
 import React, { useEffect, useMemo, useRef, useState } from 'react';
 // 2. 第三方库
 import { ArrowLeft, ExternalLink, Globe } from 'lucide-react';
 import { toast } from 'sonner';
 // 3. 业务 Provider
 import { useRouter } from '@/providers/RouterProvider';
 import { useThemeMode } from '@/providers/ThemeModeProvider';
 // 4. 配置 / 存储
 import { FeatureConfig, FEATURES } from '@/config/features';
 import { storageUtil } from '@/utils/chromeStorage';
 // 5. i18n
 import { useTranslation } from 'react-i18next';
 import { normalizeLanguage, SUPPORTED_LANGUAGES } from '@/i18n';
 // 6. 本地组件
 import TextMode from './TextMode';
 import { ZONES } from './constants';
 // 7. UI 组件
 import SwitchButtonGroup from '@/components/SwitchButtonGroup';
 import { Button } from '@/components/ui/button';
 // 8. 工具函数 / Hook
 import { cn } from '@/lib/utils';
 import { useLazyTranslation } from '@/utils/useLazyTranslation';
 // 9. 类型
 import type { PageType, StorageSchema } from '@/types/storage';
 ```
 ### 3.2 路径别名
 - `@/` 映射到项目根目录
 - **跨目录导入**：使用 `@/` 绝对别名
 - **同目录导入**：使用相对路径 `./`
 ```typescript
 // ✅ 绝对别名导入 — 跨目录
 import { cn } from '@/lib/utils';
 import { storageUtil } from '@/utils/chromeStorage';
 import type { StorageSchema } from '@/types/storage';
 import { Button } from '@/components/ui/button';
 // ✅ 相对导入 — 仅限同目录
 import TextMode from './TextMode';
 import { ZONES } from './constants';
 import { useTimestampConverter } from './useTimestampConverter';
 ```
 ---
 ## 4. 样式规范
 ### 4.1 `cn()` 工具函数
 统一使用 `cn()` 合并 Tailwind 类名（来自 `clsx` + `tailwind-merge`），导入自 `@/lib/utils`：
 ```typescript
 import { cn } from '@/lib/utils';
 // ✅ 条件类名 + 合并外部 className
 <div className={cn(
  'flex items-center gap-3 px-3 h-10 rounded-lg border border-border/80 bg-secondary/50',
  className,   // 外部传入的覆盖
 )} {...props}>
 // ✅ 错误状态变体
 <Input className={cn(
  'font-mono font-semibold h-10 shadow-sm placeholder:text-muted-foreground/60',
  error && 'border-destructive focus-visible:ring-destructive',
 )} />
 // ✅ 选中/未选中状态
 className={cn(
  'flex-1 inline-flex items-center justify-center font-medium whitespace-nowrap transition-all',
  sizeClasses[size],
  isSelected
    ? 'bg-background text-foreground shadow-sm font-semibold'
    : 'hover:bg-background/50 hover:text-foreground/80',
  buttonClassName,
 )}
 ```
 ### 4.2 主题 / 暗色模式
 使用 shadcn/ui 的 CSS 变量语义化类名，**禁止硬编码颜色值**：
 ```typescript
 // ✅ 语义化颜色 token — 亮/暗模式自适应
 <div className="min-h-screen bg-background text-foreground antialiased selection:bg-primary/20">
 <div className="p-5 rounded-xl border border-border bg-card text-card-foreground shadow-sm">
 // ✅ 暗色模式特殊处理
 'fixed ... bg-white dark:bg-gray-900 p-6 ...'
 // ✅ 需要固定颜色的特殊场景（如二维码白色背景保护）
 <div className="p-3 bg-white rounded-lg shadow-sm border border-border/40">
 ```
 **常用语义化 token：**
 | 用途 | 类名                                                               |
 | ---- | ------------------------------------------------------------------ |
 | 背景 | `bg-background`, `bg-card`, `bg-muted`, `bg-secondary`             |
 | 文字 | `text-foreground`, `text-card-foreground`, `text-muted-foreground` |
 | 边框 | `border-border`, `border-border/80`                                |
 | 主色 | `text-primary`, `bg-primary`, `border-primary`                     |
 | 危险 | `text-destructive`, `bg-destructive`, `border-destructive`         |
 ### 4.3 响应式设计
 移动优先，使用 `sm:` / `md:` / `lg:` 断点：
 ```typescript
 // ✅ Grid 自适应布局
 <div className="grid grid-cols-1 md:grid-cols-2 gap-4 items-stretch">
 // ✅ Dashboard 自动填充网格
 <div className="grid grid-cols-1 sm:grid-cols-[repeat(auto-fill,minmax(290px,1fr))] auto-rows-auto gap-3.5 p-3.5 w-full h-auto">
 // ✅ 弹性方向切换
 <div className="flex flex-col sm:flex-row items-stretch gap-3 w-full">
 // ✅ 内边距响应式
 <div className="p-4 sm:p-6 space-y-4">
 ```
 ---
 ## 5. 错误处理
 ### 5.1 工具函数：结果对象模式
 工具函数**不抛异常**，返回包含 `hasError` 和 `error` 字段的结果对象：
 ```typescript
 // ✅ 结果对象模式
 export function markdownToHtml(markdown: string): MarkdownToHtmlResult {
  try {
    ...
    return { html, originalLength, htmlLength, hasError: false };
  } catch (error) {
    return {
      html: '', ...
      hasError: true,
      error: error instanceof Error ? error.message : 'Markdown 解析失败',
    };
  }
 }
 ```
 ### 5.2 UI 层：try-catch + Toast
 UI 层异步操作使用 try-catch，通过 `sonner` 的 `toast` 显示错误：
 ```typescript
 import { toast } from 'sonner';
 const handleCopy = useCallback(async () => {
  try {
    await navigator.clipboard.writeText(value);
    toast.success('复制成功');
  } catch {
    toast.error('复制失败');
  }
 }, [value]);
 ```
 ### 5.3 Promise 异常隔离
 对不关心返回值的异步操作，使用 `void` + `.catch()` 隔离异常：
 ```typescript
 // ✅ void + .catch 模式
 void storageUtil.set(THEME_MODE_KEY, next).catch((err) => {
  console.error('[Theme Storage Error] Failed to persistent theme state:', err);
 });
 // ✅ async 函数调用 + .catch
 loadConfig().catch(console.error);
 ```
 ### 5.4 ErrorBoundary
 在应用顶层使用 `ErrorBoundary` 组件捕获子组件树异常：
 ```typescript
 import ErrorBoundary from '@/components/ErrorBoundary';
 <ErrorBoundary>
  <RouterContainer />
 </ErrorBoundary>
 ```
 ---
 ## 6. 命名规范
 ### 6.1 文件命名
 | 类型        | 命名模式                   | 示例                                                     |
 | ----------- | -------------------------- | -------------------------------------------------------- |
 | 页面目录    | PascalCase                 | `Timestamp/`, `Base64Converter/`, `StorageCleaner/`      |
 | 页面入口    | `index.tsx`                | `src/pages/Timestamp/index.tsx`                          |
 | 组件文件    | PascalCase `.tsx`          | `TopBar.tsx`, `LiveClock.tsx`, `ResultView.tsx`          |
 | 自定义 Hook | camelCase `.ts`            | `useTimestampConverter.ts`, `useStorageCleaner.ts`       |
 | 工具函数    | camelCase `.ts`            | `chromeStorage.ts`, `base64Converter.ts`, `clipboard.ts` |
 | 测试文件    | 与源文件同名 `.test.ts(x)` | `jwt.test.ts`, `SwitchButtonGroup.test.tsx`              |
 | 类型文件    | camelCase `.d.ts`          | `storage.d.ts`                                           |
 | 常量文件    | camelCase `.ts`            | `constants.ts`                                           |
 ### 6.2 变量 / 函数命名
 ```typescript
 // ✅ camelCase — 变量、函数、Hook
 const conversionPipeline = useMemo(...);
 const handleUseNow = useCallback(...);
 export function useTimestampConverter(): UseTimestampConverterReturn { ... }
 export function textToBase64(text: string): TextToBase64Result { ... }
 // ✅ PascalCase — 组件、类型、接口
 const LiveClock = React.memo(...);
 export interface GlobalSnackbarProps { ... }
 export type ThemeMode = 'light' | 'dark' | 'system';
 // ✅ SCREAMING_SNAKE_CASE — 常量
 const SEARCH_HISTORY_LIMIT = 10;
 const THEME_MODE_KEY = 'app/themeMode' as const;
 export const MAX_FILE_SIZE = 10 * 1024 * 1024;
 export const SUPPORTED_IMAGE_TYPES = [...] as const;
 // ✅ 布尔值 — is/has/should 前缀
 const isControlled = controlledValue !== undefined;
 const isDashboard = currentPage === 'dashboard';
 const hasError = true;
 ```
 ### 6.3 事件处理函数
 使用 `handle` 前缀命名组件内事件处理函数：
 ```typescript
 const handleUseNow = useCallback((now: number) => { ... }, []);
 const handleSelectFeature = (feature: FeatureConfig) => { ... };
 const handleFileChange = useCallback((file: File) => { ... }, []);
 const handleClean = useCallback(async () => { ... }, []);
 ```
 ---
 ## 7. 测试规范
 ### 7.1 文件组织
 测试文件放在源代码同级的 `__tests__/` 目录下：
 ```
 src/utils/__tests__/jwt.test.ts
 src/utils/__tests__/base64Converter.test.ts
 src/utils/__tests__/useStorageState.test.ts
 src/components/__tests__/SwitchButtonGroup.test.tsx
 src/components/__tests__/ErrorBoundary.test.tsx
 src/pages/Timestamp/__tests__/index.test.tsx
 ```
 ### 7.2 describe / it 命名
 `describe` 使用模块/函数名，`it` 使用中文描述行为（"应该..."）：
 ```typescript
 // ✅ 中文 describe + 中文 it
 describe('textToBase64', () => {
  it('应该编码 ASCII 文本', () => { ... });
  it('应该编码中文文本', () => { ... });
  it('应该编码空字符串', () => { ... });
 });
 // ✅ 中文 describe + 中文 it（组件测试）
 describe('SwitchButtonGroup 组件', () => {
  it('应渲染所有选项按钮', () => { ... });
  it('应高亮当前选中的按钮', () => { ... });
  it('点击未选中按钮时应触发 onChange 并传入选中值', () => { ... });
 });
 ```
 ### 7.3 Mock 模式
 - 使用 `vi.mock()` 进行模块级 Mock
 - 使用 `vi.fn()` 进行函数级 Mock
 - 使用 `vi.useFakeTimers()` 控制时间
 - **避免重复 mock `vitest.setup.ts` 中已有的内容**（chrome API、i18n、matchMedia 等）
 ```typescript
 // ✅ 模块级 Mock
 vi.mock('@/utils/chromeStorage', () => ({
  storageUtil: {
    get: vi.fn(),
    set: vi.fn(() => Promise.resolve()),
  },
 }));
 // ✅ 函数级 Mock + 断言
 const handleChange = vi.fn();
 render(<SwitchButtonGroup value="a" options={options} onChange={handleChange} />);
 fireEvent.click(screen.getByRole('button', { name: /选项B/i }));
 expect(handleChange).toHaveBeenCalledTimes(1);
 expect(handleChange).toHaveBeenCalledWith('b');
 // ✅ 定时器 Mock
 beforeEach(() => {
  vi.useFakeTimers();
  vi.clearAllMocks();
 });
 afterEach(() => {
  vi.restoreAllMocks();
  vi.useRealTimers();
 });
 ```
 ### 7.4 断言模式
 使用 Testing Library 的 DOM 查询 + Vitest 匹配器：
 ```typescript
 // ✅ 语义化查询
 expect(screen.getByRole('button', { name: /选项A/i })).toBeInTheDocument();
 expect(screen.getByTestId('normal-content')).toHaveTextContent('正常内容');
 expect(screen.queryByText('糟糕，出了点问题')).not.toBeInTheDocument();
 // ✅ CSS 类断言
 expect(button).toHaveClass('bg-background', 'text-foreground', 'shadow-sm');
 // ✅ 异步断言
 await waitFor(() => {
  expect(result.current[0]).toBe(false);
  expect(result.current[2]).toBe(true);
 });
 // ✅ renderHook 测试自定义 Hook
 const { result } = renderHook(() => useStorageState('qrCode/urlExpanded', true));
 expect(result.current[0]).toBe(true);
 ```
 ---
 ## 8. 自定义 Hook 规范
 ### 8.1 命名和结构
 - 使用 `use` 前缀命名
 - 定义返回值接口类型
 - 添加 JSDoc 注释
 ```typescript
 // ✅ 完整的 Hook 结构
 /**
 * 自定义 Hook：处理右键菜单传递的数据
 *
 * @param options - 配置选项
 * @example
 * useContextMenuData({ featureKey: 'jwt', onData: handlePayload });
 */
 export function useContextMenuData({ featureKey, onData }: UseContextMenuDataOptions): void {
  const checkAndConsumeData = useCallback(async () => { ... }, [featureKey, onData]);
  useEffect(() => { checkAndConsumeData(); }, [checkAndConsumeData]);
 }
 // ✅ 返回值接口定义
 export interface UseTimestampConverterReturn {
  mode: 'ts2dt' | 'dt2ts';
  input: string;
  result: string;
  error: string;
  setMode: (mode: 'ts2dt' | 'dt2ts') => void;
  setInput: (value: string) => void;
  handleUseNow: (now: number) => void;
 }
 export function useTimestampConverter(): UseTimestampConverterReturn { ... }
 ```
 ### 8.2 Hook 存放位置
 - **全局通用 Hook**：放在 `src/utils/` 目录下
 - **页面专属 Hook**：与页面组件同目录
 ```
 src/utils/useStorageState.ts          — Chrome Storage 状态持久化
 src/utils/useLazyTranslation.ts       — i18n 懒加载
 src/utils/useContextMenuData.ts       — 右键菜单数据
 src/utils/useDebounce.ts              — 防抖
 src/pages/Timestamp/useTimestampConverter.ts    — 页面级 Hook
 src/pages/StorageCleaner/useStorageCleaner.ts  — 页面级 Hook
 ```
 ---
 ## 9. 国际化规范
 ### 9.1 翻译键格式
 - 命名空间：`common`（默认）、`features`
 - 翻译键格式：`namespace:key`（如 `features:timestamp.title`）
 - 语言：`zh`（默认）、`en`
 ### 9.2 翻译文件结构
 ```
 i18n/locales/{zh,en}/common.json           — 全局通用翻译
 i18n/locales/{zh,en}/features.json         — 功能模块标题和描述
 i18n/locales/{zh,en}/{功能名}.json         — 各功能独立翻译
 ```
 ### 9.3 使用方式
 ```typescript
 // ✅ 页面组件 — 使用 useLazyTranslation
 import { useLazyTranslation } from '@/utils/useLazyTranslation';
 export default function Index() {
  const { t } = useLazyTranslation('timestamp');
  return <h1>{t('timestamp:title')}</h1>;
 }
 // ✅ 全局组件 — 使用 useTranslation
 import { useTranslation } from 'react-i18next';
 export function TopBar() {
  const { t } = useTranslation(['common', 'features']);
  return <span>{t('common:settings')}</span>;
 }
 ```
 ### 9.4 添加新翻译
 1. 在 `i18n/locales/{zh,en}/features.json` 添加功能标题和描述
 2. 创建 `i18n/locales/{zh,en}/{功能名}.json` 添加功能专属翻译
 3. 在 `utils/useLazyTranslation.ts` 的 `localeModules` 中注册新命名空间
 ---
 ## 10. 存储规范
 ### 10.1 StorageSchema
 所有 Chrome Storage 键必须在 `types/storage.d.ts` 的 `StorageSchema` 中声明：
 ```typescript
 export interface StorageSchema {
  'app/currentRoute': PageType;
  'app/popupRoute': PageType;
  'app/theme': string;
  'app/themeMode': 'light' | 'dark' | 'system';
  'storageCleaner/preferences': StorageCleanerPreferences;
  // ...
 }
 ```
 ### 10.2 存储操作
 使用 `utils/chromeStorage.ts` 的类型安全封装：
 ```typescript
 import { storageUtil } from '@/utils/chromeStorage';
 import type { StorageSchema } from '@/types/storage';
 // ✅ 读取
 const theme = await storageUtil.get('app/theme', 'default');
 // ✅ 写入
 await storageUtil.set('app/theme', 'dark');
 // ✅ 删除
 await storageUtil.remove('app/theme');
 ```
 ### 10.3 持久化状态 Hook
 使用 `useStorageState` 自动同步 Chrome Storage：
 ```typescript
 import { useStorageState } from '@/utils/useStorageState';
 const [themeMode, setThemeMode, isInitialized] = useStorageState(
  'app/themeMode',
  'system',
  isValidMode, // 可选的类型守卫
 );
 ```
 ---
 ## 11. 文件组织
 ### 11.1 页面组件结构
 ```
 src/pages/FeatureName/
 ├── index.tsx              # 页面 UI（纯展示，使用 shadcn/ui 组件）
 ├── useFeatureName.ts      # 业务逻辑 Hook（状态管理 + 转换逻辑）
 ├── constants.ts           # 常量定义（可选）
 ├── LiveClock.tsx          # 子组件（可选）

 # Copilot 指令
 基于 WXT 框架的浏览器扩展项目（React 19 + TypeScript），为开发者和测试人员提供效率工具：时间戳转换、存储清理、JWT 解析、JSON 工具、二维码、Base64、Markdown 等。
 ## 核心命令
 ```bash
 npm run dev              # Chrome 开发模式（支持 HMR）
 npm run dev:firefox      # Firefox 开发模式
 npm run build            # Chrome 生产构建
 npm run build:firefox    # Firefox 生产构建
 npm run zip              # 打包 Chrome 扩展（.output/*.zip）
 npm run zip:firefox      # 打包 Firefox 扩展
 npm run lint             # ESLint 检查（--max-warnings=0）
 npm run typecheck        # TypeScript 类型检查（tsc --noEmit）
 npm run test             # 运行全部单元测试（vitest run）
 npm run test:watch       # Vitest 监视模式
 npm run test:coverage    # 带覆盖率的测试
 ```
 运行单个测试文件：`npx vitest run path/to/file.test.ts`
 修改 `package.json` 后需运行 `npm install`（会自动触发 `postinstall` → `wxt prepare` 重新生成 `.wxt/` 类型声明）。
 ## CI 流水线（GitHub Actions）
 严格顺序门控，任一步骤失败则终止：
 1. **setup** — 安装依赖，缓存 `node_modules`
 2. **lint**、**typecheck**、**test** — 三者并行运行，全部通过才继续
 3. **build** — Chrome + Firefox 矩阵构建（仅当步骤 2 全部通过时执行）
 Pre-commit 钩子（`.husky/pre-commit` → `lint-staged`）：
 1. 代码文件（`*.{ts,tsx,js,jsx,mjs}`）：运行 `eslint --fix --max-warnings=0`
 2. 同一代码文件：运行 `prettier --write`
 3. 其他文件（`*.{json,css,scss,md}`）：运行 `prettier --write`
 ## 项目架构
 ### 路由（不使用 React Router）
 路由完全通过 `config/features.tsx` 中的 `FEATURES` 数组管理。每个功能定义一个 `key`（类型为 `types/storage.d.ts` 中的 `PageType`）和三个懒加载组件，分别对应 `popup`、`sidepanel`、`tab` 三种渲染模式。`providers/RouterProvider.tsx` 中的 `RouterProvider` 根据存储状态渲染当前页面。
 存在三套独立的路由作用域：`app/popupRoute`、`app/sidepanelRoute`、`app/tabRoute`，各自维护独立的可见页面列表和页面排序。
 ### 存储
 所有 Chrome Storage 键必须在 `types/storage.d.ts` 的 `StorageSchema` 中声明，键名使用 kebab-case 格式（如 `app/currentRoute`）。使用 `utils/chromeStorage.ts` 中的类型安全封装（`storageUtil.get/set/remove`）。
 Router 同时使用 `chrome.storage.local` 持久化和 `localStorage` 快照来消除首屏闪烁。
 ### 扩展通信
 使用 `@webext-core/messaging`。通信协议在 `utils/messages.ts` 中通过 `ProtocolMap` 定义。使用该模块导出的 `sendMessage` / `onMessage`，不要直接使用原生 `chrome.runtime.sendMessage`。
 ### 页面组件模式
 功能页面遵循 **UI + Hook 分离** 模式：
 ```
 pages/FeatureName/
 ├── index.tsx              # UI 组件（纯展示，使用 shadcn/ui 组件）
 ├── useFeatureName.ts      # 业务逻辑 Hook（状态管理 + 转换逻辑）
 └── constants.ts           # 常量定义（可选）
 ```
 - 页面组件调用 `useLazyTranslation('featureName')` 获取翻译函数
 - Hook 负责所有状态管理，通过返回值暴露给页面
 - 子组件可进一步拆分（如 `LiveClock.tsx`、`ResultView.tsx`）
 ### 新功能开发清单
 1. 在 `types/storage.d.ts` 的 `PageType` 联合类型中添加新成员
 2. 在 `config/features.tsx` 的 `FEATURES` 数组中添加配置（key、翻译键、图标、三种渲染模式组件）
 3. 在 `pages/` 目录创建页面组件（懒加载）：
   - `index.tsx` — 使用 `useLazyTranslation` 的 UI 组件
   - `useFeatureName.ts` — 业务逻辑 Hook
   - `constants.ts` — 常量（可选）
 4. 在 `i18n/locales/{zh,en}/features.json` 添加翻译（复杂功能可新建独立 JSON 文件）
 5. 如需新权限，更新 `wxt.config.ts` 的 `manifest.permissions`
 6. 添加对应的单元测试
 ## 关键规范
 > 完整的代码编写规范详见 [CODING_STANDARDS.md](./CODING_STANDARDS.md)。
 ### 浏览器 API
 始终使用 `wxt/browser` 导出的 `browser` 对象，而非原生 `chrome` API，以确保跨浏览器兼容性。
 ### 路径别名
 `@/` 映射到项目根目录（已在 tsconfig 和 vitest.config 中配置）。跨目录导入使用 `@/` 绝对别名，同目录导入使用 `./` 相对路径。
 ### UI 组件
 - 使用 `components/ui/` 下的 shadcn/ui 组件（button、dialog、select、input 等）
 - 图标：`lucide-react`
 - 样式：Tailwind CSS + `@/lib/utils` 中的 `cn()` 工具函数（clsx + tailwind-merge）
 - 主题：使用 shadcn/ui 语义化 token（`bg-background`、`text-foreground`、`border-border` 等），禁止硬编码颜色
 ### 代码分割
 `wxt.config.ts` 通过 `manualChunksForHtmlOnly()` 自动分组 vendor 依赖（vendor-react、vendor-i18n、vendor-qr、vendor-dnd），无需手动配置。
 ### 代码风格
 - 禁止使用 `any`（测试文件除外）
 - 未使用的变量/参数：使用 `_` 前缀（如 `_unused`）
 - Prettier：100 字符宽、单引号、尾逗号 all、LF 换行
 - ESLint 使用 `typescript-eslint` 的 `projectService: true`
 - 导出模式：页面组件 default export，工具函数/Hook 命名导出，UI 组件 forwardRef + 命名导出
 ### 测试
 - 环境：jsdom
 - 全局变量：`vitest/globals`（describe、it、expect 等无需导入）
 - Setup 文件：`vitest.setup.ts` 自动 mock 以下内容：
  - `chrome.*` / `browser.*` API（storage、tabs、runtime、cookies 等）
  - `react-i18next`（返回 key 作为翻译）
  - `@/utils/useLazyTranslation`（返回 `ns:key` 格式）
  - `window.matchMedia`
 - 测试文件命名：`__tests__/*.test.{ts,tsx}` 或 `*.test.{ts,tsx}`
 - 使用 `vi.mock()` 进行模块级 mock；避免重复 mock `vitest.setup.ts` 中已有的内容
 - 测试工具：`@testing-library/react` + `@testing-library/user-event`
 ### 国际化（i18n）
 - 命名空间：`common`（默认）、`features`
 - 翻译键格式：`namespace:key`（如 `features:timestamp.title`）
 - 语言：`zh`（默认）、`en`
 - 翻译文件：`i18n/locales/{zh,en}/{common,features}.json` + 各功能独立 JSON 文件
 - 使用 `useLazyTranslation` Hook 加载功能专属翻译
 - 回退策略：缺失的翻译键回退到 `zh`，若仍缺失则返回占位格式 `namespace:key`
 ### WXT 生成文件
 - `.wxt/` 目录由 `postinstall`（`wxt prepare`）自动生成，包含 TypeScript 类型声明和扩展 tsconfig
 - 生产构建输出到 `.output/` 目录
 - `tsconfig.json` 继承自 `./.wxt/tsconfig.json`

 ## index.ts
 i18next 初始化配置：
 - 同步加载 `common` 和 `features` 核心命名空间
 - 自定义 `chromeStorage` 语言检测器，从 Chrome Storage 读取语言偏好
 - `normalizeLanguage()` 将任意语言标识归一化为 `zh` 或 `en`
 - 语言变更时同步更新 Day.js 本地化和 localStorage 快照
 ## 翻译键格式
 - 命名空间：`common`（默认）、`features`、各功能独立命名空间
 - 键格式：`namespace:key`（如 `features:timestamp.title`、`timestamp:unitMs`）
 ## 使用方式
 ```tsx
 // 页面组件 — 懒加载翻译
 import { useLazyTranslation } from '@/utils/useLazyTranslation';
 const { t } = useLazyTranslation('timestamp');
 t('timestamp:title');
 // 全局组件 — 直接使用
 import { useTranslation } from 'react-i18next';
 const { t } = useTranslation(['common', 'features']);
 t('common:settings');
 ```
 ## 添加新翻译
 1. 在 `locales/{zh,en}/features.json` 添加功能标题和描述
 2. 创建 `locales/{zh,en}/{功能名}.json` 添加功能专属翻译
 3. 在 `utils/useLazyTranslation.ts` 的 `localeModules` 中注册新命名空间
