Page Configuration

In Nextra, the site and page structure can be configured via the co-located _meta.js files. In the docs theme, there are some extra options available to customize it further.

Those configurations affect the overall layout of the theme, especially the navigation bar and the sidebar.

Pages

The title and order of a page shown in the sidebar should be configured in the _meta.js file as key-value pairs. For example, if you have the following file structure:

You can define how the pages are shown in the sidebar via the _meta.js file:

export default {
  index: 'My Homepage',
  contact: 'Contact Us',
  about: 'About Us'
}

Folders

Folders can be configured in the same way as pages. For example:

The top-level _meta.js file contains the meta information for the top-level pages and folders:

export default {
  index: 'My Homepage',
  contact: 'Contact Us',
  fruits: 'Delicious Fruits',
  about: 'About Us'
}

And the nested _meta.js file contains the meta information for pages in the same folder:

export default {
  apple: 'Apple',
  banana: 'Banana'
}

This way, information for pages are grouped together in directories. You can move directories around without having to change the _meta.js file.

Folders with Index Page

What if I want to have a folder with an index page? We can add a MDX page with the same name and in the same directory as the folder. Let’s say we want to add /fruits route in the example above, we can create a fruits.mdx file in pages:

Then Nextra knows that the fruits key in _meta.js defines a folder with an index page. If you click that folder in the sidebar, it will open the folder and show you the fruits.mdx page at the same time.

External Links

You can add external links to the sidebar by adding an item with href in _meta.js:

export default {
  index: 'My Homepage',
  contact: 'Contact Us',
  fruits: 'Delicious Fruits',
  about: 'About Us',
  github_link: {
    title: 'Nextra',
    href: 'https://github.com/shuding/nextra'
  }
}

To always open the link in a new tab, enable the "newWindow": true option:

export default {
  index: 'My Homepage',
  contact: 'Contact Us',
  fruits: 'Delicious Fruits',
  about: 'About Us',
  github_link: {
    title: 'Nextra',
    href: 'https://github.com/shuding/nextra',
    newWindow: true
  }
}

Hidden Routes

By default, all MDX routes in the filesystem will be shown on the sidebar. But you can hide a specific pages or folders by using the "display": "hidden" configuration:

export default {
  index: 'My Homepage',
  contact: {
    display: 'hidden'
  },
  about: 'About Us'
}

The page will still be accessible via the /contact URL, but it will not be shown in the sidebar.

Navbar Items

Sub Docs

By defining a top-level page or folder as "type": "page", it will be shown as a special page on the navigation bar, instead of the sidebar. With this feature, you can have multiple “sub docs”, and special pages or links such as “Contact Us” that are always visible.

For example, you can have 2 docs folders frameworks and fruits in your project:

In your top-level _meta.js file, you can set everything as a page, instead of a normal sidebar item:

export default {
  index: {
    title: 'Home',
    type: 'page'
  },
  frameworks: {
    title: 'Frameworks',
    type: 'page'
  },
  fruits: {
    title: 'Fruits',
    type: 'page'
  },
  about: {
    title: 'About',
    type: 'page'
  }
}

And it will look like this:

You can also hide links like Home from the navbar with the "display": "hidden" option.

Menus

You can also add menus to the navbar using "type": "menu" and the "items" option:

export default {
  company: {
    title: 'Company',
    type: 'menu',
    items: {
      about: {
        title: 'About',
        href: '/about'
      },
      contact: {
        title: 'Contact Us',
        href: 'mailto:hi@example.com'
      }
    }
  }
}

Links

Same as the External Links option, you can have external links in the navbar too:

export default {
  index: {
    title: 'Home',
    type: 'page'
  },
  about: {
    title: 'About',
    type: 'page'
  },
  contact: {
    title: 'Contact Us',
    type: 'page',
    href: 'https://example.com/contact',
    newWindow: true
  }
}

Fallbacks

In the Sub Docs example above, we have to define the "type": "page" option for every page. To make it easier, you can use the "*" key to define the fallback configuration for all items in this folder:

export default {
  '*': {
    type: 'page'
  },
  index: 'Home',
  frameworks: 'Frameworks',
  fruits: 'Fruits',
  about: 'About'
}

They are equivalent where all items have "type": "page" set.

Separators

You can use a “placeholder” item with "type": "separator" to create a separator line between items in the sidebar:

export default {
  index: 'My Homepage',
  '---': {
    type: 'separator'
  },
  contact: 'Contact Us'
}

Advanced

Theme Components

You can configure the theme for each page using the "theme" option. For example, you can disable or enable specific components for specific pages:

export default {
  index: {
    title: 'Home',
    theme: {
      breadcrumb: false,
      footer: true,
      sidebar: false,
      toc: true,
      pagination: false
    }
  }
}

This option will be inherited by all child pages if set to a folder.

Layouts

By default, each page has "layout": "default" in their theme config, which is the default behavior.

Raw Layout

By default, Nextra renders the MDX content (such as h1, h2, h3 etc.) with themed components, inside a content container. You can use the "raw" layout to let Nextra to not inject any styles to the content:

export default {
  index: {
    title: 'Home',
    theme: {
      layout: 'raw'
    }
  }
}

Full Layout

You might want to render some page with the full container width and height, but keep all the other styles. You can use the "full" layout to do that:

export default {
  index: {
    title: 'Home',
    theme: {
      layout: 'full'
    }
  }
}

Typesetting

The "typesetting" option controls typesetting details like font features, heading styles and components like li and code. There are "default" and "article" typesettings available in the docs theme.

The default one is suitable for most cases like documentation, but you can use the "article" typesetting to make it look like an elegant article page:

export default {
  about: {
    title: 'About Us',
    theme: {
      typesetting: 'article'
    }
  }
}
