Default Theme Config

Theme config lets you customize your theme. You can define theme config via the themeConfig option in the config file:

export default {
  lang: 'en-US',
  title: 'VitePress',
  description: 'Vite & Vue powered static site generator.',

  // Theme related configurations.
  themeConfig: {
    logo: '/logo.svg',
    nav: [...],
    sidebar: { ... }
  }
}

The options documented on this page only apply to the default theme. Different themes expect different theme config. When using a custom theme, the theme config object will be passed to the theme so the theme can define conditional behavior based on it.

i18nRouting

• Type: boolean

Changing locale to say zh will change the URL from /foo (or /en/foo/) to /zh/foo. You can disable this behavior by setting themeConfig.i18nRouting to false.

logo

• Type: ThemeableImage

Logo file to display in nav bar, right before the site title. Accepts a path string, or an object to set a different logo for light/dark mode.

export default {
  themeConfig: {
    logo: '/logo.svg'
  }
}

type ThemeableImage =
  | string
  | { src: string; alt?: string }
  | { light: string; dark: string; alt?: string }

siteTitle

• Type: string | false

You can customize this item to replace the default site title (title in app config) in nav. When set to false, title in nav will be disabled. Useful when you have logo that already contains the site title text.

    siteTitle: 'Hello World'
  }
}
