App Configs ​

App configs are where you can define the global settings of the site. App configs define fundamental settings that are not only limited to the theme configs such as configuration for "base directory", or the "title" of the site.

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

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.

typescript
export default {
  base: '/base/'
}

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.

typescript
export default {
  lang: 'en-US'
}

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.

typescript
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.

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

description ​

  • Type: string
  • Default: A VitePress site

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

typescript
export default {
  description: 'A VitePress site'
}

markdown ​

  • Type: MarkdownOption

Configre 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.

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

Below shows the the full option you may define within this object.

typescript
interface MarkdownOptions extends MarkdownIt.Options {
  // Syntax highlight theme for Shiki.
  // See: https://github.com/shikijs/shiki/blob/main/docs/themes.md#all-themes
  theme?: Shiki.Theme | { light: Shiki.Theme, dark: Shiki.Theme }

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

  // markdown-it-anchor plugin options.
  // See: https://github.com/valeriangalliat/markdown-it-anchor
  anchor?: {
    permalink?: anchor.AnchorOptions['permalink']
  }

  // markdown-it-attrs plugin options.
  // See: https://github.com/arve0/markdown-it-attrs
  attrs?: {
    leftDelimiter?: string
    rightDelimiter?: string
    allowedAttributes?: string[]
    disable?: boolean
  }

  // markdown-it-toc-done-right plugin options
  // https://github.com/nagaozen/markdown-it-toc-done-right
  toc?: any

  // Configure the Markdown-it instance to fully customize
  // how it works.
  config?: (md: MarkdownIt) => void
}

appearance ​

  • Type: boolean
  • Default: true

Whether to enable "Dark Mode" or not. If the option is set to true, it adds .dark class to the <html> tag depending on the users preference.

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.

typescript
export default {
  appearance: true
}

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.

typescript
export default {
  lastUpdated: true
}
