Sitemap Generation

VitePress comes with out-of-the-box support for generating a sitemap.xml file for your site. To enable it, add the following to your .vitepress/config.js:

export default {
  sitemap: {
    hostname: 'https://example.com'
  }
}

To have <lastmod> tags in your sitemap.xml, you can enable the lastUpdated option.

Options

Sitemap support is powered by the sitemap module. You can pass any options supported by it to the sitemap option in your config file. These will be passed directly to the SitemapStream constructor. Refer to the sitemap documentation for more details. Example:

export default {
  sitemap: {
    hostname: 'https://example.com',
    lastmodDateOnly: false
  }
}

If you're using base in your config, you should append it to the hostname option:

export default {
  base: '/my-site/',
  sitemap: {
    hostname: 'https://example.com/my-site/'
  }
}

transformItems Hook

You can use the sitemap.transformItems hook to modify the sitemap items before they are written to the sitemap.xml file. This hook is called with an array of sitemap items and expects an array of sitemap items to be returned. Example:

export default {
  sitemap: {
    hostname: 'https://example.com',
    transformItems: (items) => {
      // add new items or modify/filter existing items
      items.push({
        url: '/extra-page',
        changefreq: 'monthly',
        priority: 0.8
      })
      return items
    }
  }
}
