+title: 国际化
+---
+
+目前的默认文案是中文(`zh-CN`)，如果需要使用其他语言，可以在初始化时进行配置，也可以在运行时切换，可以参考下面的方案。
+
+## 初始化
+
+```typescript
+import { useI18n } from '@idux/components'
+import { en_US } from '@idux/components/i18n/languages'
+
+
+useI18n(en_US)
+
+```
+
+## 运行时切换
+
+```typescript
+import { addI18n, useI18n } from '@idux/components'
+import { es_ES, en_US } from '@idux/components/i18n/languages'
+
+// 首先需要先添加多语言包
+addI18n([es_ES, en_US])
+
+useI18n('es_ES')
+
+// 运行时切换
+setTimeout(()=> useI18n('en_US'), 3000)
+
+```
+
+注意：`es_ES`, `en_US` 是语言包名称，以下表格也遵循同样的规则。
+
+## 支持语言
+
+| 语言             | 语言包名 |
+| ---------------- | ------ |
+| 英语（美式）     | en_US  |
+| 西班牙语         | es_ES  |
+| 中文简体         | zh_CN  |
+| 中文繁体         | zh_TW  |
