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.
Read more about Nextra’s _meta.js
files
here.
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:
- _meta.js
- about.mdx
- contact.mdx
- index.mdx
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'
}
If any routes are not listed in the _meta.js
file, they will be appended to
the end of the sidebar and sorted alphabetically, and the title will be
formatted with Title based on filename.
Folders
Folders can be configured in the same way as pages. For example:
- _meta.js
- apple.mdx
- banana.mdx
- _meta.js
- about.mdx
- contact.mdx
- index.mdx
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:
- _meta.js
- apple.mdx
- banana.mdx
- _meta.js
- about.mdx
- contact.mdx
- fruits.mdx
- index.mdx
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
}
}
You can use this option to link to relative internal links too.
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:
- react.mdx
- svelte.mdx
- vue.mdx
- apple.mdx
- banana.mdx
- _meta.js
- about.mdx
- index.mdx
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:[email protected]'
}
}
}
}
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'
}
Use JSX elements to change the look of titles and separator lines in the sidebar.
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'
}
}
}
