# Internationalization
|
||||
|
||||
To use the built-in i18n features, one needs to create a directory structure as follows:
|
||||
|
||||
```
|
||||
docs/
|
||||
├─ es/
|
||||
│ ├─ foo.md
|
||||
├─ fr/
|
||||
│ ├─ foo.md
|
||||
├─ foo.md
|
||||
```
|
||||
|
||||
Then in `docs/.vitepress/config.ts`:
|
||||
|
||||
```ts
|
||||
import { defineConfig } from 'vitepress'
|
||||
|
||||
export default defineConfig({
|
||||
// shared properties and other top-level stuff...
|
||||
|
||||
locales: {
|
||||
root: {
|
||||
label: 'English',
|
||||
lang: 'en'
|
||||
},
|
||||
fr: {
|
||||
label: 'French',
|
||||
lang: 'fr', // optional, will be added as `lang` attribute on `html` tag
|
||||
link: '/fr/guide' // default /fr/ -- shows on navbar translations menu, can be external
|
||||
|
||||
// other locale specific properties...
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
The following properties can be overridden for each locale (including root):
|
||||
|
||||
```ts
|
||||
interface LocaleSpecificConfig<ThemeConfig = any> {
|
||||
lang?: string
|
||||
dir?: string
|
||||
title?: string
|
||||
titleTemplate?: string | boolean
|
||||
description?: string
|
||||
head?: HeadConfig[] // will be merged with existing head entries, duplicate meta tags are automatically removed
|
||||
themeConfig?: ThemeConfig // will be shallow merged, common stuff can be put in top-level themeConfig entry
|
||||
}
|
||||
```
|
||||
|
||||
Refer [`DefaultTheme.Config`](https://github.com/vuejs/vitepress/blob/main/types/default-theme.d.ts) interface for details on customizing the placeholder texts of the default theme. Don't override `themeConfig.algolia` or `themeConfig.carbonAds` at locale-level. Refer [Algolia docs](./theme-search#i18n) for using multilingual search.
|
||||
|
||||
**Pro tip:** Config file can be stored at `docs/.vitepress/config/index.ts` too. It might help you organize stuff by creating a configuration file per locale and then merge and export them from `index.ts`.
|
||||
|
||||
## Separate directory for each locale
|
||||
|
||||
The following is a perfectly fine structure:
|
||||
|
||||
```
|
||||
docs/
|
||||
├─ en/
|
||||
│ ├─ foo.md
|
||||
├─ es/
|
||||
│ ├─ foo.md
|
||||
├─ fr/
|
||||
├─ foo.md
|
||||
```
|
||||
|
||||
However, VitePress won't redirect `/` to `/en/` by default. You'll need to configure your server for that. For example, on Netlify, you can add a `docs/public/_redirects` file like this:
|
||||
|
||||
```
|
||||
/* /es/:splat 302 Language=es
|
||||
/* /fr/:splat 302 Language=fr
|
||||
/* /en/:splat 302
|
||||
```
|
||||
|
||||
**Pro tip:** If using the above approach, you can use `nf_lang` cookie to persist user's language choice. A very basic way to do this is register a watcher inside the [setup](./theme-introduction#using-a-custom-theme) function of custom theme:
|
||||
|
||||
```ts
|
||||
// docs/.vitepress/theme/index.ts
|
||||
import DefaultTheme from 'vitepress/theme'
|
||||
|
||||
export default {
|
||||
...DefaultTheme,
|
||||
setup() {
|
||||
const { lang } = useData()
|
||||
watchEffect(() => {
|
||||
if (inBrowser) {
|
||||
document.cookie = `nf_lang=${lang.value}; expires=Mon, 1 Jan 2024 00:00:00 UTC; path=/`
|
||||
}
|
||||
})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## RTL Support (Experimental)
|
||||
|
||||
For RTL support, specify `dir: 'rtl'` in config and use some RTLCSS PostCSS plugin like <https://github.com/MohammadYounes/rtlcss>, <https://github.com/vkalinichev/postcss-rtl> or <https://github.com/elchininet/postcss-rtlcss>. You'll need to configure your PostCSS plugin to use `:where([dir="ltr"])` and `:where([dir="rtl"])` as prefixes to prevent CSS specificity issues.

# Search
|
||||
|
||||
Documentation coming soon...
|
||||
VitePress supports searching your docs site using [Algolia DocSearch](https://docsearch.algolia.com/docs/what-is-docsearch). Refer their getting started guide. In your `.vitepress/config.ts` you'll need to provide at least the following to make it work:
|
||||
|
||||
```ts
|
||||
import { defineConfig } from 'vitepress'
|
||||
|
||||
export default defineConfig({
|
||||
themeConfig: {
|
||||
algolia: {
|
||||
appId: '...',
|
||||
apiKey: '...',
|
||||
indexName: '...'
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
If you are not eligible for DocSearch, you might wanna use some community plugins like <https://github.com/emersonbottero/vitepress-plugin-search> or explore some custom solutions on [this GitHub thread](https://github.com/vuejs/vitepress/issues/670).
|
||||
|
||||
## i18n
|
||||
|
||||
You can use a config like this to use multilingual search:
|
||||
|
||||
```ts
|
||||
import { defineConfig } from 'vitepress'
|
||||
|
||||
export default defineConfig({
|
||||
// ...
|
||||
themeConfig: {
|
||||
// ...
|
||||
|
||||
algolia: {
|
||||
appId: '...',
|
||||
apiKey: '...',
|
||||
indexName: '...',
|
||||
locales: {
|
||||
zh: {
|
||||
placeholder: '搜索文档',
|
||||
translations: {
|
||||
button: {
|
||||
buttonText: '搜索文档',
|
||||
buttonAriaLabel: '搜索文档'
|
||||
},
|
||||
modal: {
|
||||
searchBox: {
|
||||
resetButtonTitle: '清除查询条件',
|
||||
resetButtonAriaLabel: '清除查询条件',
|
||||
cancelButtonText: '取消',
|
||||
cancelButtonAriaLabel: '取消'
|
||||
},
|
||||
startScreen: {
|
||||
recentSearchesTitle: '搜索历史',
|
||||
noRecentSearchesText: '没有搜索历史',
|
||||
saveRecentSearchButtonTitle: '保存至搜索历史',
|
||||
removeRecentSearchButtonTitle: '从搜索历史中移除',
|
||||
favoriteSearchesTitle: '收藏',
|
||||
removeFavoriteSearchButtonTitle: '从收藏中移除'
|
||||
},
|
||||
errorScreen: {
|
||||
titleText: '无法获取结果',
|
||||
helpText: '你可能需要检查你的网络连接'
|
||||
},
|
||||
footer: {
|
||||
selectText: '选择',
|
||||
navigateText: '切换',
|
||||
closeText: '关闭',
|
||||
searchByText: '搜索提供者'
|
||||
},
|
||||
noResultsScreen: {
|
||||
noResultsText: '无法找到相关结果',
|
||||
suggestedQueryText: '你可以尝试查询',
|
||||
reportMissingResultsText: '你认为该查询应该有结果？',
|
||||
reportMissingResultsLinkText: '点击反馈'
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
[These options](https://github.com/vuejs/vitepress/blob/main/types/docsearch.d.ts) can be overridden. Refer official Algolia docs to learn more about them.
