Edit Link

Edit Link lets you display a link to edit the page on Git management services such as GitHub, or GitLab. To enable it, add themeConfig.editLink options to your config.

export default {
  themeConfig: {
    editLink: {
      pattern: 'https://github.com/vuejs/vitepress/edit/main/docs/:path'
    }
  }
}

The pattern option defines the URL structure for the link, and :path is going to be replaced with the page path.

By default, this will add the link text "Edit this page" at the bottom of the doc page. You may customize this text by defining the text option.

export default {
  themeConfig: {
    editLink: {
      pattern: 'https://github.com/vuejs/vitepress/edit/main/docs/:path',
      text: 'Edit this page on GitHub'
    }
  }
}
