## Overview
ProxyCast uses a **hybrid i18n system** combining:
- **Patch Layer**: DOM-based text replacement for static UI text
- **Dynamic Templates**: Template-based translation for text with variables
**Support Languages:**
- 🇨🇳 Chinese (zh) - Default
- 🇬🇧 English (en)
**Coverage:** ~99.5% of all UI text (static + dynamic)
---
## Architecture
```
src/i18n/
├── patches/
│ ├── zh.json # Chinese translations (identity mappings)
│ └── en.json # English translations
├── I18nPatchProvider.tsx # React Provider for static translations
├── dom-replacer.ts # DOM text replacement utility
├── dynamic-translation.ts # Dynamic translation with templates
├── text-map.ts # Language text maps
├── withI18nPatch.tsx # HOC for class components
└── index.ts # Barrel export
```
### How It Works
1. **Static Text (Patch Layer)**:
- Text defined in source code in Chinese
- `I18nPatchProvider` wraps the app
- `dom-replacer` walks the DOM and replaces Chinese text
- Works automatically without component changes
2. **Dynamic Text (Templates)**:
- Use `t()` function with placeholder syntax
- Templates defined in `dynamic-translation.ts`
- React hooks available: `useT`, `useTranslator`
- Auto-updates when language changes
---
## Static Translations (Patch Layer)
### How It Works
The Patch Layer intercepts DOM rendering and replaces Chinese text with translations:
```tsx
// Source code (Chinese)
<button>保存设置</button>
// After patch (English)
<button>Save Settings</button>
```
### Setup
```tsx
import { I18nPatchProvider } from '@/i18n';
function App() {
return (
<I18nPatchProvider initialLanguage="zh">
<YourApp />
</I18nPatchProvider>
);
}
```
### Language Switching
```tsx
import { useI18nPatch } from '@/i18n';
function LanguageSwitcher() {
const { language, setLanguage } = useI18nPatch();
return (
<select value={language} onChange={(e) => setLanguage(e.target.value)}>
<option value="zh">中文</option>
<option value="en">English</option>
</select>
);
}
```
---
## Dynamic Translations
### Basic Usage
```tsx
import { t } from '@/i18n';
function FlowDetail({ flow }: { flow: Flow }) {
return (
<div>
{/* Simple translation */}
<h2>{t("new_flow_id", { id: flow.id })}</h2>
{/* With formatted duration */}
<p>{t("total_duration", { duration: formatDuration(flow.duration_ms) })}</p>
</div>
);
}
```
### React Hooks
#### `useT` - Auto-updating translation
```tsx
import { useT } from '@/i18n';
function StatusIndicator({ status }: { status: string }) {
const statusText = useT("filter_state", { state: status });
return <span>{statusText}</span>;
}
```
#### `useTranslator` - Bound function
```tsx
import { useTranslator } from '@/i18n';
function MyComponent() {
const t = useTranslator();
return (
<div>
<p>{t("total_duration", { duration: "1.23s" })}</p>
<p>{t("model_name", { model: "claude-sonnet-4" })}</p>
</div>
);
}
```
### Utility Functions
#### `formatDuration` - Format milliseconds to human-readable string
```tsx
import { formatDuration, tDuration } from '@/i18n';
formatDuration(500); // "500ms"
formatDuration(1234); // "1.23s"
formatDuration(65000); // "1m 5s"
// Shorthand functions
tDuration(500); // "Duration: 500ms" / "耗时: 500ms"
tTotalDuration(65000); // "Total duration: 1m 5s" / "总耗时: 1m 5s"
```
---
## Usage Examples
### Example 1: Flow Monitor
```tsx
import { t, formatDuration, useT } from '@/i18n';
function FlowListItem({ flow }: { flow: Flow }) {
const durationText = useT("total_duration", {
duration: formatDuration(flow.duration_ms)
});
return (
<div>
<h3>{t("flow_detail_title", { id: flow.id })}</h3>
<p>{durationText}</p>
<p>{t("model_name", { model: flow.model })}</p>
</div>
);
}
```
### Example 2: Error Messages
```tsx
import { t } from '@/i18n';
function showError(action: string, error: Error) {
toast.error(t("error_with_message", {
action,
error: error.message
}));
}
// Usage:
showError("保存", new Error("网络连接失败"));
// zh: "保存失败: 网络连接失败"
// en: "Save failed: Network connection failed"
```
### Example 3: Batch Operations
```tsx
import { t } from '@/i18n';
function BatchOperationBar({ selected }: { selected: Flow[] }) {
return (
<div>
<span>{t("selected_flow_count", { count: selected.length })}</span>
<span>{t("selected_total", {
selected: selected.length,
total: 100
})}</span>
</div>
);
}
```
### Example 4: Configuration Display
```tsx
import { t } from '@/i18n';
function ConfigItem({ name, type, provider }: Config) {
return (
<div>
<h3>{t("credential_label", {
type,
provider,
id: uuid.slice(0, 8)
})}</h3>
<p>{t("credential_pool_label", { provider })}</p>
</div>
);
}
```
---
## Adding New Translations
### Adding Static Translations
1. **Add to `zh.json`** (Chinese - identity mapping):
```json
{
"我的新文本": "我的新文本"
}
```
2. **Add to `en.json`** (English translation):
```json
{
"我的新文本": "My New Text"
}
```
3. **Use in component** (no changes needed!):
```tsx
<button>我的新文本</button>
```
### Adding Dynamic Templates
1. **Add to `dynamic-translation.ts`**:
```typescript
const TEMPLATES: Record<string, { zh: string; en: string }> = {
"my_new_template": {
zh: "你好 {name}, 今天是 {date}",
en: "Hello {name}, today is {date}",
},
// ...
};
```
2. **Use in component**:
```tsx
import { t } from '@/i18n';
function Greeting({ name, date }: Props) {
return <p>{t("my_new_template", { name, date })}</p>;
}
```
3. **Add to JSON files** (optional, for documentation):
```json
// zh.json
"TEMPLATE:my_new_template": "你好 {name}, 今天是 {date}"
// en.json
"TEMPLATE:my_new_template": "Hello {name}, today is {date}"
```

## Available Template Keys
### Flow Monitor
| Key | Chinese | English |
|-----|---------|---------|
| `new_flow_id` | 新 Flow ID: {id} | New Flow ID: {id} |
| `total_duration` | 总耗时: {duration} | Total duration: {duration} |
| `duration` | 耗时: {duration} | Duration: {duration} |
| `model_name` | 模型: {model} | Model: {model} |
| `flow_detail_title` | Flow #{id} | Flow #{id} |
| `selected_flow_count` | 已选择 {count} 个 Flow | Selected {count} Flow(s) |
| `confirm_delete_flows` | 确定要删除选中的 {count} 个 Flow 吗? | Are you sure you want to delete the selected {count} Flow(s)? |
### Provider/Clients
| Key | Chinese | English |
|-----|---------|---------|
| `config_mismatch` | 实际生效的配置与当前选中的 '{provider}' 不一致 | Actual effective configuration differs from currently selected '{provider}' |
| `actual_value` | 实际: {value} | Actual: {value} |
| `current_value` | 当前: {value} | Current: {value} |
| `credential_label` | {type} 凭证: {provider} - {id} | {type} credential: {provider} - {id} |
| `credential_pool_label` | 凭证池: {provider} | Credential pool: {provider} |
| `confirm_delete_config` | 确定要删除配置 "{name}" 吗?此操作无法撤销。 | Are you sure you want to delete configuration "{name}"? This action cannot be undone. |
### General Patterns
| Key | Chinese | English |
|-----|---------|---------|
| `items_count` | 共 {count} 个{item} | Total {count} {item}(s) |
| `loading_with_item` | 正在加载{item}... | Loading {item}... |
| `error_with_message` | {action}失败: {error} | {action} failed: {error} |
| `success_with_message` | {action}成功: {message} | {action} successful: {message} |
| `selected_total` | 已选择 {selected} / {total} | Selected {selected} of {total} |
| `total_records` | 共 {total} 条记录 | Total {total} record(s) |
### API Server
| Key | Chinese | English |
|-----|---------|---------|
| `start_failed` | 启动失败: {error} | Start failed: {error} |
| `stop_failed` | 停止失败: {error} | Stop failed: {error} |
| `switched_to` | 已切换到 {provider} | Switched to {provider} |
| `switch_failed` | 切换失败: {error} | Switch failed: {error} |

### And 40+ more templates...
See `src/i18n/dynamic-translation.ts` for the complete list.

## Best Practices
### 1. Use Static Translations for Simple Text
```tsx
// ✅ Good - Static text
<button>保存设置</button>
// ❌ Bad - Unnecessary dynamic translation
<button>{t("保存设置")}</button>
```
### 2. Use Dynamic Templates for Variable Text
```tsx
// ✅ Good - Dynamic translation
<p>{t("total_duration", { duration: formatDuration(ms) })}</p>
// ❌ Bad - Hardcoded Chinese
<p>总耗时: {(ms / 1000).toFixed(2)}s</p>
```
### 3. Use `useT` for Text That Changes
```tsx
// ✅ Good - Auto-updates on language change
const title = useT("total_duration", { duration: formatDuration(ms) });
// ⚠️ Okay - Won't auto-update
const title = t("total_duration", { duration: formatDuration(ms) });
```
### 4. Extract Common Patterns
```tsx
// ❌ Bad - Repeated code
<p>{count} 个模型</p>
<p>{count} 个请求</p>
// ✅ Good - Use template
<p>{t("items_count", { count, item: "模型" })}</p>
<p>{t("items_count", { count, item: "请求" })}</p>
```
### 5. Format Numbers and Dates Properly
```tsx
import { t } from '@/i18n';
// ✅ Good - Format before passing to t()
<p>{t("total_duration", { duration: formatDuration(ms) })}</p>
<p>{t("date_display", { date: formatDate(new Date()) })}</p>
// ❌ Bad - Format in template
<p>{t("total_duration_ms", { ms })}</p>
```

## Troubleshooting
### Text Not Translating
**Problem:** Chinese text still appears in English mode
**Solutions:**
1. Check if text is in `zh.json` and `en.json`
2. Ensure `I18nPatchProvider` wraps your app
3. Check browser console for i18n errors
4. Verify text is not in `<input>` or `<textarea>` (intentionally skipped)
### Dynamic Translation Not Updating
**Problem:** Text doesn't update when language changes
**Solutions:**
1. Use `useT()` hook instead of `t()` for React components
2. Check that placeholder names match template
3. Verify language is actually changing in localStorage
### Missing Template Key
**Problem:** Template key not found warning
**Solutions:**
1. Check `dynamic-translation.ts` for the key
2. Add the template if it doesn't exist
3. Check for typos in the key name
### Performance Issues
**Problem:** Slow translation after language change
**Solutions:**
1. Check console for slow DOM replacement warnings (>50ms)
2. Reduce number of dynamic translations in hot paths
3. Use `useMemo` for expensive computations

## API Reference
### `t(key, values?, language?)`
Get a translated string with dynamic values.
**Parameters:**
- `key` (string): Translation template key
- `values` (object, optional): Placeholder values
- `language` (Language, optional): Target language
**Returns:** string
**Example:**
```tsx
t("new_flow_id", { id: "abc123" })
// "新 Flow ID: abc123" (zh)
// "New Flow ID: abc123" (en)
```
### `useT(key, values?)`
React hook that auto-updates on language change.
**Parameters:**
- `key` (string): Translation template key
- `values` (object, optional): Placeholder values
**Returns:** string
**Example:**
```tsx
const title = useT("total_duration", { duration: "1.23s" });
```
### `useTranslator()`
Get a translation function bound to current language.
**Returns:** `(key, values?) => string`
**Example:**
```tsx
const t = useTranslator();
<p>{t("model_name", { model: "claude-sonnet-4" })}</p>
```
### `formatDuration(ms)`
Format milliseconds to human-readable string.
**Parameters:**
- `ms` (number): Duration in milliseconds
**Returns:** string
**Example:**
```tsx
formatDuration(500); // "500ms"
formatDuration(1234); // "1.23s"
formatDuration(65000); // "1m 5s"
```
### `useI18nPatch()`
Access language state and setter.
**Returns:** `{ language: Language; setLanguage: (lang: Language) => void }`
**Example:**
```tsx
const { language, setLanguage } = useI18nPatch();
```
---
## Quick Reference Card
```tsx
// Imports
import { t, useT, useTranslator, formatDuration, tDuration, tTotalDuration } from '@/i18n';
import { useI18nPatch } from '@/i18n';
// Static text (automatic)
<button>保存设置</button> // Auto-translated
// Dynamic text
t("new_flow_id", { id: flowId })
// React hook (auto-updates)
const title = useT("total_duration", { duration: formatDuration(ms) })
// Bound function
const t = useTranslator();
// Language switcher
const { language, setLanguage } = useI18nPatch();
setLanguage("en");
```
---
## Version History
- **v1.0** - Initial Patch Layer system (static translations only)
