# Runtime API
|
|
|
|
VitePress offers several built-in APIs to let you access app data. VitePress also comes with a few built-in components that can be used globally.
|
|
|
|
The helper methods are globally importable from `vitepress` and are typically used in custom theme Vue components. However, they are also usable inside `.md` pages because markdown files are compiled into Vue [Single-File Components](https://vuejs.org/guide/scaling-up/sfc.html).
|
|
|
|
Methods that start with `use*` indicates that it is a [Vue 3 Composition API](https://vuejs.org/guide/introduction.html#composition-api) function ("Composable") that can only be used inside `setup()` or `<script setup>`.
|
|
|
|
## `useData` <Badge type="info" text="composable" />
|
|
|
|
Returns page-specific data. The returned object has the following type:
|
|
|
|
```ts
|
|
interface VitePressData<T = any> {
|
|
/**
|
|
* Site-level metadata
|
|
*/
|
|
site: Ref<SiteData<T>>
|
|
/**
|
|
* themeConfig from .vitepress/config.js
|
|
*/
|
|
theme: Ref<T>
|
|
/**
|
|
* Page-level metadata
|
|
*/
|
|
page: Ref<PageData>
|
|
/**
|
|
* Page frontmatter
|
|
*/
|
|
frontmatter: Ref<PageData['frontmatter']>
|
|
/**
|
|
* Dynamic route params
|
|
*/
|
|
params: Ref<PageData['params']>
|
|
title: Ref<string>
|
|
description: Ref<string>
|
|
lang: Ref<string>
|
|
isDark: Ref<boolean>
|
|
dir: Ref<string>
|
|
localeIndex: Ref<string>
|
|
}
|
|
|
|
interface PageData {
|
|
title: string
|
|
titleTemplate?: string | boolean
|
|
description: string
|
|
relativePath: string
|
|
filePath: string,
|
|
headers: Header[]
|
|
frontmatter: Record<string, any>
|
|
params?: Record<string, any>
|
|
isNotFound?: boolean
|
|
lastUpdated?: number
|
|
}
|
|
```
|
|
|
|
**Example:**
|
|
|
|
```vue
|
|
<script setup>
|
|
import { useData } from 'vitepress'
|
|
|
|
const { theme } = useData()
|
|
</script>
|
|
|
|
<template>
|
|
<h1>{{ theme.footer.copyright }}</h1>
|
|
</template>
|
|
```
|
|
|
|
## `useRoute` <Badge type="info" text="composable" />
|
|
|
|
Returns the current route object with the following type:
|
|
|
|
```ts
|
|
interface Route {
|
|
path: string
|
|
data: PageData
|
|
component: Component | null
|
|
}
|
|
```
|
|
|
|
## `useRouter` <Badge type="info" text="composable" />
|
|
|
|
Returns the VitePress router instance so you can programmatically navigate to another page.
|
|
|
|
```ts
|
|
interface Router {
|
|
/**
|
|
* Current route.
|
|
*/
|
|
route: Route
|
|
/**
|
|
* Navigate to a new URL.
|
|
*/
|
|
go: (to?: string) => Promise<void>
|
|
/**
|
|
* Called before the route changes. Return `false` to cancel the navigation.
|
|
*/
|
|
onBeforeRouteChange?: (to: string) => Awaitable<void | boolean>
|
|
/**
|
|
* Called before the page component is loaded (after the history state is
|
|
* updated). Return `false` to cancel the navigation.
|
|
*/
|
|
onBeforePageLoad?: (to: string) => Awaitable<void | boolean>
|
|
/**
|
|
* Called after the route changes.
|
|
*/
|
|
onAfterRouteChanged?: (to: string) => Awaitable<void>
|
|
}
|
|
```
|
|
|
|
## `withBase` <Badge type="info" text="helper" />
|
|
|
|
- **Type**: `(path: string) => string`
|
|
|
|
Appends the configured [`base`](./site-config#base) to a given URL path. Also see [Base URL](../guide/asset-handling#base-url).
|
|
|
|
## `<Content />` <Badge type="info" text="component" />
|
|
|
|
The `<Content />` component displays the rendered markdown contents. Useful [when creating your own theme](../guide/custom-theme).
|
|
|
|
```vue
|
|
<template>
|
|
<h1>Custom Layout!</h1>
|
|
<Content />
|
|
</template>
|
|
```
|
|
|
|
## `<ClientOnly />` <Badge type="info" text="component" />
|
|
|
|
The `<ClientOnly />` component renders its slot only at client side.
|
|
|
|
Because VitePress applications are server-rendered in Node.js when generating static builds, any Vue usage must conform to the universal code requirements. In short, make sure to only access Browser / DOM APIs in beforeMount or mounted hooks.
|
|
|
|
If you are using or demoing components that are not SSR-friendly (for example, contain custom directives), you can wrap them inside the `ClientOnly` component.
|
|
|
|
```vue-html
|
|
<ClientOnly>
|
|
<NonSSRFriendlyComponent />
|
|
</ClientOnly>
|
|
```
|

|
```md

|
