# Task 04: Locale Store - Compilation Evidence
## Date: 2026-03-13
## Files Created
- src/renderer/src/stores/localeStore.ts
## Verification
### TypeScript Check
```bash
npx tsc --noEmit
# Result: PASSED (no errors)
```
### Store Implementation
- Uses Zustand with persist middleware
- Imports LocaleCode and DEFAULT_LOCALE from @shared/types/locale
- Persists only the locale state value (partialize pattern)
- Exports useLocaleStore hook
### State Shape
```typescript
interface LocaleState {
locale: LocaleCode; // "zh-CN" | "ja-JP" | "en-US"
setLocale: (locale: LocaleCode) => void;
}
```
### Default Value
- locale: "zh-CN" (from DEFAULT_LOCALE constant)

# Task 06: Configure @lobehub/i18n-cli
## Completed Actions
1. **Installed @lobehub/i18n-cli@^1.26.1** as dev dependency
2. **Added npm script**: `"i18n": "lobe-i18n"` to package.json
3. **Verified CLI works**: `npm run i18n -- --help` returns usage info
## Existing Configuration (.i18nrc.js)
```javascript
module.exports = {
entry: ['src/renderer/src/locales/default/*.json'],
output: 'src/renderer/src/locales',
entryLocale: 'zh-CN',
outputLocales: ['en-US', 'ja-JP'],
apiKey: process.env.OPENAI_API_KEY || '',
apiModel: 'gpt-4o-mini',
};
```
## CLI Usage
```bash
# Run translation
npm run i18n
# With markdown translation
npm run i18n -- --with-md
# Lint translations
npm run i18n -- --lint
```
## Notes
- Source locale: zh-CN (in `locales/default/`)
- Output locales: en-US, ja-JP
- API key must be set via `OPENAI_API_KEY` environment variable
- Uses gpt-4o-mini model for translation

## [2026-03-14] Locale Not Synced Between Processes
### 问题描述
Renderer process 和 Main process 的 locale 状态没有同步。
### 复现步骤
1. 用户在 UI 中切换语言 (例如从 zh-CN 到 en-US)
2. localeStore 更新 localStoragei18next 切换语言
3. 但是 Main process 的 `config.json` 仍然是旧值
4. Main process 的错误消息使用旧语言
### 根本原因
- `localeStore.setLocale()` 只更新 Zustand state
- 没有调用 `window.api.setLocale()` 同步到 Main process
### 解决方案
需要在以下位置添加同步逻辑:
1. **localeStore.ts**: 修改 `setLocale` action
```typescript
setLocale: async (locale) => {
set({ locale });
await window.api.setLocale({ locale });
}
```
2. **App.tsx**: 在初始化时从 Main process 读取 locale
```typescript
useEffect(() => {
const initLocale = async () => {
const result = await window.api.getLocale();
if (result.success) {
useLocaleStore.getState().setLocale(result.data);
i18n.changeLanguage(result.data);
}
};
initLocale();
}, []);
```
### 影响范围
- `src/renderer/src/stores/localeStore.ts`
- `src/renderer/src/App.tsx` 或 `src/renderer/src/main.tsx`
### 优先级
高 - 影响用户体验Main process 错误消息语言不一致

# i18n Integration Learnings
## 2026-03-13 - Locale File Structure
### Structure Created
- **Directory**: `src/renderer/src/locales/`
- **Subdirectories**: `default/`, `zh-CN/`, `ja-JP/`, `en-US/`
- **Files per language**: `common.json`, `domain.json`, `settings.json`, `errors.json`
### Translation Key Format
- Use flat key structure (no nested objects): `"app.title"` instead of `{"app": {"title": ""}}`
- Each file contains 20+ translation keys (exceeds minimum 5)
- Keys are organized by feature area:
- `common.json`: UI buttons, labels, status messages
- `domain.json`: Domain management specific translations
- `settings.json`: Settings page translations
- `errors.json`: Error messages and validation errors
### Language Codes
- `default/`: Source language (Chinese)
- `zh-CN/`: Simplified Chinese
- `en-US/`: English (US)
- `ja-JP/`: Japanese
### Best Practices
1. Keep translation keys descriptive (e.g., `collapseSidebar` not `cs`)
2. Group related keys together in the same file
3. Use consistent naming convention (camelCase for keys)
## [2026-03-13] - Locale Store Implementation
### Pattern: Zustand Store with Persist Middleware
Created `localeStore.ts` following the existing `domainStore.ts` pattern:
```typescript
export const useLocaleStore = create<LocaleState>()(
persist(
(set) => ({
locale: DEFAULT_LOCALE,
setLocale: (locale) => set({ locale }),
}),
{
name: "locale-storage",
partialize: (state) => ({ locale: state.locale }),
},
),
);
```
### Key Decisions
- Use `partialize` to only persist the `locale` value, not actions
- Import `DEFAULT_LOCALE` from shared types to ensure consistency
- Store key is `locale-storage` in localStorage
### File Location
- Store: `src/renderer/src/stores/localeStore.ts`
- Types: `src/shared/types/locale.ts` (LocaleCode, DEFAULT_LOCALE)
## [2026-03-13] - i18n Instance Configuration
### Pattern: Static Import Configuration
Created `i18n.ts` with static imports for all locale files:
```typescript
// Import locale files statically
import commonZHCN from "./locales/zh-CN/common.json";
import domainZHCN from "./locales/zh-CN/domain.json";
// ... (all 12 files imported)
const resources = {
"zh-CN": { common: commonZHCN, domain: domainZHCN, ... },
"ja-JP": { ... },
"en-US": { ... },
};
```
### Key Configuration Options
- **fallbackLng**: `zh-CN` - fallback to Chinese if translation missing
- **defaultNS**: `common` - default namespace for `t()` calls
- **ns**: `['common', 'domain', 'settings', 'errors']` - 4 namespaces
- **escapeValue**: `false` - React handles XSS protection
- **detection**: localStorage + navigator order, caches to localStorage
### Language Detector Configuration
```typescript
detection: {
order: ["localStorage", "navigator"],
caches: ["localStorage"],
lookupLocalStorage: "i18nextLng",
}
```
This ensures:
1. First check localStorage for saved preference
2. Fall back to browser language
3. Persist detected/selected language to localStorage
### File Location
- Configuration: `src/renderer/src/i18n.ts`
- Must be imported in `main.tsx` before React renders
## [2026-03-13] - Dependencies Installation
### Installed Packages
- `i18next@25.8.18` - Core i18n framework
- `react-i18next@16.5.8` - React bindings for i18next
- `i18next-browser-languagedetector@8.2.1` - Browser language detection
- `@lobehub/i18n-cli@1.26.1` - LobeHub i18n CLI tool
### Notes
- React-i18next correctly dedupes i18next dependency
- All packages are latest stable versions
- LobeHub UI uses @emoji-mart/react which has peer dependency warning for React 19 (non-blocking)
## [2026-03-13] - @lobehub/i18n-cli Configuration
### Configuration Pattern
- Binary name: `lobe-i18n` (not `@lobehub/i18n-cli`)
- Config file: `.i18nrc.js` (CommonJS format)
- Uses environment variable for API key: `OPENAI_API_KEY`
### Locale Structure for CLI
- `locales/default/` - Source files (Chinese)
- `locales/zh-CN/` - Same as default (for consistency)
- `locales/en-US/` - English translations
- `locales/ja-JP/` - Japanese translations
### Important Notes
- entryLocale = source language (zh-CN = Chinese)
- outputLocales = target languages for AI translation
- Do NOT put zh-CN in outputLocales if it's the source
- The CLI supports markdown translation with `--with-md` flag
### npm script
```json
"i18n": "lobe-i18n"
```
Run with: `npm run i18n`
## 2026-03-14 - I18nextProvider Integration
### Changes Made
- Added `I18nextProvider` import from `react-i18next`
- Added `i18n` instance import from `./i18n`
- Wrapped `<ThemeProvider>` with `<I18nextProvider i18n={i18n}>` to enable i18n throughout the app
### Integration Pattern
```tsx
<I18nextProvider i18n={i18n}>
<ThemeProvider>
<AntdApp>
<App />
</AntdApp>
</ThemeProvider>
</I18nextProvider>
```
### Notes
- The i18n instance from `./i18n` is already initialized (chained `.use().init()`)
- No additional initialization needed in main.tsx
- I18nextProvider wraps ThemeProvider (not the other way around)
- I18nextProvider wraps ThemeProvider (not the other way around)
## [2026-03-14] - Ant Design Locale Synchronization
### Pattern: Locale Mapping
- Use a mapping function to convert i18next locale codes to Ant Design locale objects
- Supported mapping:
- `zh-CN``zhCN` (antd/locale/zh_CN)
- `ja-JP``jaJP` (antd/locale/ja_JP)
- `en-US``enUS` (antd/locale/en_US)
### Implementation
```typescript
// Import all locales
import zhCN from "antd/locale/zh_CN";
import jaJP from "antd/locale/ja_JP";
import enUS from "antd/locale/en_US";
import type { Locale } from "antd/es/locale";
// Map locale code to Ant Design locale
const getAntdLocale = React.useCallback((localeCode: string): Locale => {
switch (localeCode) {
case "ja-JP":
return jaJP;
case "en-US":
return enUS;
case "zh-CN":
default:
return zhCN;
}
}, []);
// Memoize the result
const antdLocale = React.useMemo(
() => getAntdLocale(locale),
[locale, getAntdLocale]
);
// Use in ConfigProvider
<ConfigProvider locale={antdLocale}>
```
### Key Points
- Use `React.useCallback` for the mapping function to prevent unnecessary re-renders
- Use `React.useMemo` to memoize the locale result based on locale changes
- Import `Locale` type from `antd/es/locale` for type safety
- Default fallback to `zhCN` for unsupported locales
## [2026-03-14] - Preload Locale API Exposure
### Files Modified
- `src/shared/types/ipc.ts` - Added `SetLocaleParams` interface
- `src/preload/index.ts` - Added `getLocale` and `setLocale` IPC invocations
- `src/preload/index.d.ts` - Added type declarations for locale API
### Pattern: IPC Exposure in Preload
```typescript
// In preload/index.ts
const api: SelfAPI = {
// ... other APIs
// Locale
getLocale: () => ipcRenderer.invoke("getLocale"),
setLocale: (params) => ipcRenderer.invoke("setLocale", params),
};
```
### Type Declaration Pattern
```typescript
// In preload/index.d.ts
import type { SetLocaleParams } from "@shared/types/ipc";
import type { LocaleCode } from "@shared/types/locale";
export interface SelfAPI {
// ... other methods
// ==================== Locale ====================
getLocale: () => Promise<Result<LocaleCode>>;
setLocale: (params: SetLocaleParams) => Promise<Result<void>>;
}
```
### Key Points
- Follow existing IPC patterns (invoke with channel name and params)
- Use `Result<T>` wrapper for return types
- Import types from `@shared/types/` path alias
- Add IPC type params interface to `ipc.ts`
## 2026-03-14 - Main Process IPC Locale Synchronization
### Implementation Pattern
**Storage Layer** (`src/main/storage.ts`):
- Added `locale?: LocaleCode` to `AppConfig` interface
- Implemented `getLocale()` - reads locale from config.json, returns `DEFAULT_LOCALE` if not set
- Implemented `setLocale(locale: LocaleCode)` - saves locale to config.json
- Uses existing `readJsonFile`/`writeJsonFile` pattern for consistency
**IPC Handlers** (`src/main/ipc-handlers.ts`):
- `getLocale` handler: Returns `Promise<Result<LocaleCode>>`
- `setLocale` handler: Takes `SetLocaleParams`, returns `Promise<Result<void>>`
- Uses existing `handle<P, T>` helper wrapper for error handling
**Types** (`src/shared/types/ipc.ts`):
- `SetLocaleParams` interface already exists with `locale: LocaleCode` property
- Follows pattern of other params objects (e.g., `CreateDomainParams`, `UpdateDomainParams`)
**Preload** (`src/preload/index.ts`):
- `getLocale: () => ipcRenderer.invoke("getLocale")`
- `setLocale: (params) => ipcRenderer.invoke("setLocale", params)`
### Key Decisions
1. **Not using react-i18next in main process**: Main process uses simple locale string storage, not full i18n library
2. **Params object pattern**: `setLocale` uses `SetLocaleParams` object instead of `LocaleCode` directly for consistency with other IPC handlers
3. **Default fallback**: `getLocale()` returns `DEFAULT_LOCALE` ("zh-CN") when no locale is set
4. **Storage location**: Locale stored in `config.json` alongside domains array
### File Changes Summary
- `src/main/storage.ts`: Added `getLocale()` and `setLocale()` functions
- `src/main/ipc-handlers.ts`: Added `registerGetLocale()` and `registerSetLocale()` handlers
- `src/shared/types/ipc.ts`: `SetLocaleParams` already existed
- `src/preload/index.d.ts`: Locale API types already existed
- `src/preload/index.ts`: Locale methods already existed
## 2026-03-14 - App.tsx Internationalization
### Pattern Used
- Import: `import { useTranslation } from "react-i18next";`
- Hook usage: `const { t } = useTranslation();`
- Translation call: `{t('translationKey')}`
### Translation Keys Added
- `deployFiles` - "部署文件" / "Deploy Files" / "ファイルをデプロイ"
- `versionHistory` - "版本历史" / "Version History" / "バージョン履歴"
- `settings` - "设置" / "Settings" / "設定"
### Existing Keys Used
- `collapseSidebar` - "收起侧边栏"
- `expandSidebar` - "展开侧边栏"
### Files Modified
1. `src/renderer/src/App.tsx` - Added useTranslation hook, replaced hardcoded text
2. `src/renderer/src/locales/zh-CN/common.json` - Added new keys
3. `src/renderer/src/locales/en-US/common.json` - Added new keys
4. `src/renderer/src/locales/ja-JP/common.json` - Added new keys
5. `src/renderer/src/locales/default/common.json` - Added new keys
### i18n Setup
- Uses `react-i18next` with `I18nextProvider` wrapper in main.tsx
- Default namespace: `common`
- Fallback language: `zh-CN`
- Locale files: `./locales/{lang}/{namespace}.json`
## [2026-03-14] - DomainManager Component Internationalization
### Files Modified
- `src/renderer/src/components/DomainManager/DomainManager.tsx`
- `src/renderer/src/locales/default/domain.json`
### Pattern: useTranslation Hook with Namespace
```typescript
import { useTranslation } from "react-i18next";
const DomainManager: React.FC<DomainManagerProps> = ({...}) => {
const { t } = useTranslation("domain");
// ...
return <h2>{t("domainManagement")}</h2>;
};
```
### Translation Keys Added
- `noDomainSelected`: "未选择 Domain"
- `addDomainTooltip`: "添加 Domain"
- `domainManagement`: "Domain 管理"
- `add`: "添加"
- `noDomainConfig`: "暂无 Domain 配置"
- `addFirstDomainConfig`: "添加第一个 Domain"
### Key Points
1. Use `useTranslation("domain")` to specify the namespace
2. Replace all hardcoded Chinese text with `t("key")` calls
3. Use regex `[\u4e00-\u9fff]` to find remaining Chinese characters for verification
4. Keep translation keys in camelCase format
## [2026-03-14] - Main Process Error Message Internationalization
### Challenge: Cannot Use react-i18next in Main Process
The main process cannot use `react-i18next` because:
1. It's designed for React rendering, not Node.js/Electron main process
2. Main process needs synchronous error message access
3. Main process errors can be thrown before renderer initializes
### Solution: Simple Custom i18n Module
Created `src/main/errors.ts` with a simple translation approach:
```typescript
import type { LocaleCode } from "@shared/types/locale";
import { getLocale } from "./storage";
const errorMessages: Record<LocaleCode, Record<MainErrorKey, string>> = {
"zh-CN": { domainNotFound: "域名未找到", ... },
"en-US": { domainNotFound: "Domain not found", ... },
"ja-JP": { domainNotFound: "ドメインが見つかりません", ... },
};
export function getErrorMessage(
key: MainErrorKey,
params?: ErrorParams,
locale?: LocaleCode,
): string {
const targetLocale = locale ?? getLocale();
const messages = errorMessages[targetLocale] || errorMessages["zh-CN"];
return interpolate(messages[key], params);
}
```
### Files Modified
1. `src/main/errors.ts` - NEW: Error message module with translations
2. `src/main/ipc-handlers.ts` - Updated all error throws to use `getErrorMessage()`
3. `src/main/kintone-api.ts` - Updated fallback errors to use i18n
### Error Keys Added
- `domainNotFound` - Domain not found errors
- `domainDuplicate` - Duplicate domain+username errors
- `connectionFailed` - Connection test failures
- `unknownError` - Generic fallback error
- `rollbackNotImplemented` - Feature not implemented error
- `encryptPasswordFailed` - Password encryption errors
- `decryptPasswordFailed` - Password decryption errors
### Circular Dependency Consideration
**IMPORTANT**: `errors.ts` imports `getLocale` from `storage.ts`. Therefore, `storage.ts` CANNOT import from `errors.ts`.
- `storage.ts` password encrypt/decrypt errors remain hardcoded (they are internal system errors)
- Only user-facing errors in IPC handlers are internationalized
### Interpolation Pattern
For errors with dynamic values, use `{{placeholder}}` syntax:
```typescript
// In errors.ts
const messages = {
domainDuplicate: "Domain \"{{domain}}\" with user \"{{username}}\" already exists.",
};
// Usage
getErrorMessage("domainDuplicate", { domain: "example.com", username: "admin" });
```
### Test Verification
Tests show i18n working correctly:
```
Invalid credentials test result: { success: false, error: '连接失败' }
```
The error message '连接失败' is in Chinese (the current locale setting).
## [2026-03-14] Locale Persistence Verification
### 验证结果
#### ✅ Renderer Process Persistence (正常)
1. **localeStore** (`src/renderer/src/stores/localeStore.ts`)
- 使用 Zustand 的 `persist` 中间件
- localStorage key: `locale-storage`
- 只持久化 `locale` 字段 (通过 `partialize`)
- 实现正确
2. **i18next** (`src/renderer/src/i18n.ts`)
- 使用 `i18next-browser-languagedetector`
- localStorage key: `i18nextLng`
- 检测顺序: localStorage → navigator
- 实现正确
#### ✅ Main Process Persistence (正常)
1. **storage.ts** (`src/main/storage.ts`)
- `getLocale()`: 从 `config.json` 读取 locale
- `setLocale()`: 写入 `config.json`
- 默认值: `DEFAULT_LOCALE` (zh-CN)
- 实现正确
2. **IPC Handlers** (`src/main/ipc-handlers.ts`)
- `registerGetLocale()`: 返回存储的 locale
- `registerSetLocale()`: 保存 locale 到 config.json
- 实现正确
3. **Error Messages** (`src/main/errors.ts`)
- `getErrorMessage()`: 使用 `getLocale()` 获取当前语言
- 支持错误消息本地化
- 实现正确
#### ❌ CRITICAL ISSUE: Renderer 和 Main Process 没有同步!
**问题**:
- Renderer 修改语言时,只更新 localStorage**没有调用 `window.api.setLocale()`**
- Main process 的 `config.json` 与 localStorage 不同步
- Main process 错误消息可能使用错误的语言
**证据**:
- `localeStore.ts``setLocale` action 只更新 Zustand state
- `App.tsx` 使用 `useLocaleStore().locale` 但没有同步到 main process
- `i18n.ts` 的 LanguageDetector 只检测 localStorage不涉及 main process
**影响**:
- 重启应用后main process 的错误消息语言可能与 UI 不一致
- `getErrorMessage()` 会使用 `config.json` 中可能过时的 locale
### 修复建议
需要在 renderer 和 main process 之间建立同步机制:
1. **方案 A (推荐): App 启动时同步**
- 在 App 初始化时,读取 main process 的 locale
- 设置 localeStore 和 i18next
- 用户修改语言时,同时调用 `window.api.setLocale()`
2. **方案 B: 双向绑定**
- localeStore 的 `setLocale` 同时调用 IPC
- 使用 useEffect 监听 locale 变化并同步
### 首次启动处理
当前实现已经正确处理:
- `getLocale()` 返回 `DEFAULT_LOCALE` 如果没有存储
- i18next 的 detector 会尝试使用系统语言 (`navigator`)
- 首次启动会使用系统语言 (如果支持) 或 fallback 到 zh-CN
## [2026-03-14] - Settings Component with Language Switcher
### Component Structure
- **Directory**: `src/renderer/src/components/Settings/`
- **Files**: `Settings.tsx`, `index.ts`
- **Pattern**: Functional component with antd-style
### Implementation Pattern
```typescript
import { useTranslation } from "react-i18next";
import { Radio, Typography } from "antd";
import { createStyles } from "antd-style";
import { useLocaleStore } from "@renderer/stores/localeStore";
import { LOCALES, type LocaleCode } from "@shared/types/locale";
const Settings: React.FC = () => {
const { t } = useTranslation("settings");
const { styles } = useStyles();
const { locale, setLocale } = useLocaleStore();
const i18n = useTranslation().i18n;
const handleLocaleChange = (newLocale: LocaleCode) => {
setLocale(newLocale); // Update Zustand store
i18n.changeLanguage(newLocale); // Update i18next
};
return (
<Radio.Group value={locale} onChange={(e) => handleLocaleChange(e.target.value)}>
{LOCALES.map((loc) => (
<Radio key={loc.code} value={loc.code}>
{loc.nativeName}
</Radio>
))}
</Radio.Group>
);
};
```
### Key Design Decisions
1. **Use LOCALES constant**: Import from `@shared/types/locale` for consistent locale data
2. **Dual update**: Update both localeStore and i18n when language changes
3. **Radio.Group styling**: Custom CSS for better UX with native name and English name display
4. **Namespace usage**: Use `useTranslation("settings")` for settings-specific translations
### Translation Keys Used
- `settings.json`: `language` - "语言" / "Language" / "言語"
### UI Design
- Radio options styled as cards with border
- Shows both native name (e.g., "简体中文") and English name (e.g., "Chinese Simplified")
- Hover effect with primary color border and background
- Selected state highlighted with primary color
### Note on Synchronization
The component updates both `localeStore` and `i18n`, but does NOT call `window.api.setLocale()` to sync with main process. This is a known limitation documented in the learnings file above. Future work should add main process sync.

## 2026-03-14 - Component Internationalization (Wave 3)
### New Namespaces Created
- `app.json` - AppDetail, AppList components
- `deploy.json` - DeployDialog component
- `file.json` - FileUploader, CodeViewer components
- `version.json` - VersionHistory component
### Translation Key Naming Convention
- Actions: `loadApps`, `saveConfig`, `testConnection`
- States: `loading`, `connected`, `deploying`
- Labels: `fileName`, `position`, `type`
- Messages: `loadAppsFailed`, `deploySuccess`
### Cross-Namespace Reference Pattern
```typescript
// Reference other namespace's translations
t("cancel", { ns: "common" })
t("selectApp", { ns: "app" })
```
### Interpolation Pattern
```typescript
// JSON file
"totalApps": "共 {{count}} 个应用"
// Component usage
t("totalApps", { count: displayApps.length })
```
### Components Internationalized
1. **DomainManager** - domain namespace
2. **DomainForm** - domain namespace
3. **DomainList** - domain namespace
4. **AppDetail** - app namespace
5. **AppList** - app namespace
6. **CodeViewer** - file namespace
7. **DeployDialog** - deploy namespace
8. **FileUploader** - file namespace
9. **VersionHistory** - version namespace
### i18n.ts Update Pattern
When adding new namespaces:
1. Add imports for all locales
2. Add to resources object for each language
3. Add to `ns` array
```typescript
// Example
import appZHCN from "./locales/zh-CN/app.json";
// ...
const resources = {
"zh-CN": { ..., app: appZHCN, ... },
// ...
};
// ...
ns: ["common", "domain", "settings", "errors", "app", "deploy", "file", "version"],
```
## [2026-03-14] - Renderer/Main Process Locale Synchronization Fix
### Problem
Renderer stored locale in localStorage (via Zustand persist), main process stored in config.json - they were NOT synced. When user changed language in UI, main process error messages still used old language.
### Solution: Bidirectional Sync
**1. Settings.tsx - Sync to Main Process on Change**
```typescript
const handleLocaleChange = async (newLocale: LocaleCode) => {
setLocale(newLocale);
i18n.changeLanguage(newLocale);
// Sync locale to main process
await window.api.setLocale({ locale: newLocale });
};
```
**2. App.tsx - Sync from Main Process on Mount**
```typescript
const setLocaleStore = useLocaleStore((state) => state.setLocale);
// Sync locale from main process on mount
React.useEffect(() => {
const syncLocaleFromMain = async () => {
const result = await window.api.getLocale();
if (result.success && result.data) {
setLocaleStore(result.data);
i18n.changeLanguage(result.data);
}
};
syncLocaleFromMain();
}, [setLocaleStore]);
```
### Key Points
1. **On language change**: Update localStorage (Zustand), i18next, AND main process config.json
2. **On app startup**: Read locale from main process and sync to renderer
3. **Use async/await**: IPC calls are asynchronous
4. **Import i18n directly**: Need direct reference to i18n instance for changeLanguage() in useEffect
### Files Modified
- `src/renderer/src/components/Settings/Settings.tsx` - Added `window.api.setLocale()` call
- `src/renderer/src/App.tsx` - Added useEffect to sync from main process on mount
```
## [2026-03-14] - Code Quality Review - Critical Parsing Errors Found
### VERDICT: FAIL
| Check | Status | Count |
|-------|--------|-------|
| TypeScript | PASS | 0 errors |
| ESLint | FAIL | 11 parsing errors, 1 warning |
| `as any` | PASS | 0 found |
| `@ts-ignore` | WARNING | 2 found (acceptable) |
| Empty catches | PASS | 0 found |
### Critical Issues (P0 - Parsing Errors)
**Root Cause**: Incomplete i18n integration - leftover duplicate code from merging translated and untranslated code versions.
#### 1. Duplicate `import {` statements (5 files)
All files have duplicate `import {` on lines 8-9:
- `src/renderer/src/components/AppDetail/AppDetail.tsx`
- `src/renderer/src/components/AppList/AppList.tsx`
- `src/renderer/src/components/DeployDialog/DeployDialog.tsx`
- `src/renderer/src/components/VersionHistory/VersionHistory.tsx`
#### 2. Duplicate function parameters (2 files)
Parameters duplicated inside function body:
- `src/renderer/src/components/CodeViewer/CodeViewer.tsx` (lines 68-72)
- `src/renderer/src/components/FileUploader/FileUploader.tsx` (lines 68-72)
#### 3. Duplicate code blocks (2 files)
- `src/main/ipc-handlers.ts` (lines 127-128): Duplicate error message string - leftover hardcoded Chinese
- `src/renderer/src/components/DomainManager/DomainForm.tsx` (lines 166-169): Duplicate `else` block with hardcoded Chinese text
### ESLint Warning (P3)
- `src/renderer/src/App.tsx:242` - Missing dependency `setIsResizing` in useCallback
### Acceptable @ts-ignore (P2)
- `src/preload/index.ts:50,52` - Used for non-isolated context fallback (acceptable)
### Prevention
- After large-scale refactoring (like i18n integration), always run `npm run lint` before committing
- Use automated checks in CI/CD pipeline
- Code review should catch duplicate code blocks

- Wave 3 (Tasks 11-14): Component i18n, main process errors
- Wave 4 (Tasks 15-17): Settings page, language switcher, persistence
### Code Quality Issues Found
⚠️ **CRITICAL: Duplicate Code Blocks**
The following files contain duplicate code blocks that need cleanup:
1. **`src/renderer/src/i18n.ts`**:
- Lines 14-17 duplicate lines 6-13 (imports)
- Lines 26-28 duplicate lines 18-25 (imports)
- Lines 38-40 duplicate lines 30-37 (imports)
- Lines 75-94 duplicate lines 43-74 (resources object)
2. **`src/renderer/src/components/Settings/Settings.tsx`**:
- Lines 81-83 duplicate lines 76-80 (handleLocaleChange function)
3. **`src/renderer/src/App.tsx`**:
- Lines 159-160 duplicate line 158 (`const { styles } = useStyles();`)
- Lines 191-192 duplicate lines 176-177 (useState declarations)
4. **`src/main/ipc-handlers.ts`**:
- Lines 127-129 contain incomplete/duplicate code block after getErrorMessage call
5. **`src/renderer/src/main.tsx`**:
- Line 14: Ant Design locale hardcoded as `locale={zhCN}` instead of dynamic
### VERDICT
**Must Have**: 5/5 ✅ PASS
**Must NOT Have**: 4/4 ✅ PASS
**Tasks**: 17/17 ✅ PASS
**SCOPE FIDELITY: COMPLIANT**
However, **code quality issues must be fixed** before final approval. The duplicate code blocks are merge conflicts or copy-paste errors that will cause:
- TypeScript compilation errors
- Runtime errors
- Incorrect behavior
### Recommended Actions
1. Remove duplicate imports in `i18n.ts`
2. Remove duplicate `resources` object definition in `i18n.ts`
3. Remove duplicate `handleLocaleChange` body in `Settings.tsx`
4. Remove duplicate `useStyles()` call in `App.tsx`
5. Remove duplicate useState declarations in `App.tsx`
6. Fix incomplete code block in `ipc-handlers.ts`
7. Consider making Ant Design locale dynamic in `main.tsx` (currently hardcoded)
