App Config

App config is where you can define the global settings of the site. App config options define settings that apply to every VitePress site, regardless of what theme it is using. For example, the base directory or the title of the site.

export default {
  // app level config options
  lang: 'en-US',
  title: 'VitePress',
  description: 'Vite & Vue powered static site generator.',
  ...
}

appearance

Type: boolean | 'dark'
Default: true

Whether to enable dark mode or not.

If the option is set to true, the default theme will be determined by the user's preferred color scheme.
If the option is set to dark, the theme will be dark by default, unless the user manually toggles it.
If the option is set to false, users will not be able to toggle the theme.

It also injects inline script that tries to read users settings from local storage by vitepress-theme-appearance key and restores users preferred color mode.

export default {
  appearance: true
}

base

Type: string
Default: /

The base URL the site will be deployed at. You will need to set this if you plan to deploy your site under a sub path, for example, GitHub pages. If you plan to deploy your site to https://foo.github.io/bar/, then you should set base to '/bar/'. It should always start and end with a slash.

The base is automatically prepended to all the URLs that start with / in other options, so you only need to specify it once.

export default {
  base: '/base/'
}

description

Type: string
Default: A VitePress site

Description for the site. This will render as a <meta> tag in the page HTML.

export default {
  description: 'A VitePress site'
}

head

Type: HeadConfig[]
Default: []

Additional elements to render in the <head> tag in the page HTML. The user-added tags are rendered before the closing head tag, after VitePress tags.

export default {
  head: [
    [
      'link',
      { rel: 'preconnect', href: 'https://fonts.gstatic.com', crossorigin: '' }
    ]
    // would render: <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin />
  ]
}

type HeadConfig =
  | [string, Record<string, string>]
  | [string, Record<string, string>, string]

ignoreDeadLinks

Type: boolean | 'localhostLinks'
Default: false

When set to true, VitePress will not fail builds due to dead links. When set to localhostLinks, the build will fail on dead links, but won't check localhost links.

export default {
  ignoreDeadLinks: true
}

lang

Type: string
Default: en-US

The lang attribute for the site. This will render as a <html lang="en-US"> tag in the page HTML.

export default {
  lang: 'en-US'
}

lastUpdated

Type: boolean
Default: false

Use git commit to get the timestamp. This option enables the default theme to display the page's last updated time. You can customize the text via themeConfig.lastUpdatedText option.

export default {
  lastUpdated: true
}

markdown

Type: MarkdownOption

Configure Markdown parser options. VitePress uses Markdown-it as the parser, and Shiki to highlight language syntax. Inside this option, you may pass various Markdown related options to fit your needs.

export default {
  markdown: {
    theme: 'material-theme-palenight',
    lineNumbers: true
  }
}

Below are all the options that you can have in this object:

interface MarkdownOptions extends MarkdownIt.Options {
  // Custom theme for syntax highlighting.
  // You can use an existing theme.
  // See: https://github.com/shikijs/shiki/blob/main/docs/themes.md#all-themes
  // Or add your own theme.
  // See: https://github.com/shikijs/shiki/blob/main/docs/themes.md#loading-theme
  theme?:
    | Shiki.IThemeRegistration
    | { light: Shiki.IThemeRegistration; dark: Shiki.IThemeRegistration }

  // Enable line numbers in code block.
  lineNumbers?: boolean

}

outDir

Type: string
Default: ./.vitepress/dist

The build output location for the site, relative to project root (docs folder if you're running vitepress build docs).

export default {
  outDir: '../public'
}

cacheDir

Type: string
Default: ./.vitepress/cache

The directory for cache files, relative to project root (docs folder if you're running vitepress build docs). See also: cacheDir.

export default {
  cacheDir: './.vitepress/.vite'
}

srcDir

Type: string
Default: .

The directory where your markdown pages are stored, relative to project root.

export default {
  srcDir: './src'

title

Type: string
Default: VitePress

Title for the site. This will be displayed in the nav bar. Also used as the suffix for all page titles unless titleTemplate is defined.

export default {
  title: 'VitePress'
}

titleTemplate

Type: string | boolean

The suffix for the title. For example, if you set title as VitePress and set titleTemplate as My Site, the html title becomes VitePress | My Site.

Set false to disable the feature. If the option is undefined, then the value of title option will be used.

export default {
  title: 'VitePress',
  titleTemplate: 'Vite & Vue powered static site generator'
}

To configure a title separator other than |, you can omit title and use the :title symbol in titleTemplate.

  titleTemplate: ':title - Vitepress'
}

cleanUrls

Type: boolean
Default: false

Allows removing trailing .html from URLs.

export default {
  cleanUrls: true

WARNING

Enabling this may require additional configuration on your hosting platform. For it to work, your server must serve /foo.html on requesting /foo without a redirect.

export default {
  rewrites: {

Build Hooks

VitePress build hooks allow you to add new functionality and behaviors to your website:

Sitemap
Search Indexing
PWA
Teleports

buildEnd

Type: (siteConfig: SiteConfig) => Awaitable<void>

buildEnd is a build CLI hook, it will run after build (SSG) finish but before VitePress CLI process exits.

export default {
  async buildEnd(siteConfig) {
    // ...
  }
}

postRender

Type: (context: SSGContext) => Awaitable<SSGContext | void>

postRender is a build hook, called when SSG rendering is done. It will allow you to handle the teleports content during SSG.

export default {
  async postRender(context) {
    // ...
  }
}

interface SSGContext {
  content: string
  teleports?: Record<string, string>
  [key: string]: any
}

transformHead

Type: (context: TransformContext) => Awaitable<HeadConfig[]>

transformHead is a build hook to transform the head before generating each page. It will allow you to add head entries that cannot be statically added to your VitePress config. You only need to return extra entries, they will be merged automatically with the existing ones.

WARNING

Don't mutate anything inside the ctx.

export default {
  async transformHead(context) {
    // ...
  }
}

interface TransformContext {
  siteConfig: SiteConfig
  siteData: SiteData
  pageData: PageData
  title: string
  description: string
  head: HeadConfig[]
  content: string
}

transformHtml

Type: (code: string, id: string, ctx: TransformContext) => Awaitable<string | void>

transformHtml is a build hook to transform the content of each page before saving to disk.

WARNING

Don't mutate anything inside the ctx. Also, modifying the html content may cause hydration problems in runtime.

export default {
  async transformHtml(code, id, context) {
    // ...
  }
}

transformPageData

Type: (pageData: PageData) => Awaitable<Partial<PageData> | { [key: string]: any } | void>

transformPageData is a hook to transform the pageData of each page. You can directly mutate pageData or return changed values which will be merged into PageData.

export default {
  async transformPageData(pageData) {
    pageData.contributors = await getPageContributors(pageData.relativePath)
  }

  // or return data to be merged
  async transformPageData(pageData) {
    return {
      contributors: await getPageContributors(pageData.relativePath)
    }
  }
}
