Theme configuration

This configuration applies to all main themes.

Common​

Color mode​

The classic theme provides by default light and dark mode support, with a navbar switch for the user.

It is possible to customize the color mode support within the colorMode object.

Accepted fields:

NameTypeDefaultDescription
defaultMode'light' | 'dark''light'The color mode when user first visits the site.
disableSwitchbooleanfalseHides the switch in the navbar. Useful if you want to support a single color mode.
respectPrefersColorSchemebooleanfalseWhether to use the prefers-color-scheme media-query, using user system preferences, instead of the hardcoded defaultMode.
switchConfigSee belowSee belowDark/light switch icon options.
switchConfig.darkIconstring'🌜'Icon for the switch while in dark mode.
switchConfig.darkIconStyleJSX style object (see documentation){}CSS to apply to dark icon.
switchConfig.lightIconstring'🌞'Icon for the switch while in light mode.
switchConfig.lightIconStyleJSX style object{}CSS to apply to light icon.

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    colorMode: {
      defaultMode: 'light',
      disableSwitch: false,
      respectPrefersColorScheme: false,
      switchConfig: {
        darkIcon: '🌙',
        darkIconStyle: {
          marginLeft: '2px',
        },
        // Unicode icons such as '\u2600' will work
        // Unicode with 5 chars require brackets: '\u{1F602}'
        lightIcon: '\u{1F602}',
        lightIconStyle: {
          marginLeft: '1px',
        },
      },
    },
  },
};
caution

With respectPrefersColorScheme: true, the defaultMode is overridden by user system preferences.

If you only want to support one color mode, you likely want to ignore user system preferences.

Meta image​

You can configure a default image that will be used for your meta tag, in particular og:image and twitter:image.

Accepted fields:

NameTypeDefaultDescription
imagestringundefinedThe meta image URL for the site. Relative to your site's "static" directory. Cannot be SVGs. Can be external URLs too.

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    image: 'img/docusaurus.png',
  },
};

Metadata​

You can configure additional html metadata (and override existing ones).

Accepted fields:

NameTypeDefaultDescription
metadataMetadata[][]Any field will be directly passed to the <meta /> tag. Possible fields include id, name, property, content, itemprop, etc.

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    metadata: [{name: 'twitter:card', content: 'summary'}],
  },
};

Announcement bar​

Sometimes you want to announce something in your website. Just for such a case, you can add an announcement bar. This is a non-fixed and optionally dismissable panel above the navbar. All configuration are in the announcementBar object.

Accepted fields:

NameTypeDefaultDescription
idstring'announcement-bar'Any value that will identify this message.
contentstring''The text content of the announcement. HTML will be interpolated.
backgroundColorstring'#fff'Background color of the entire bar.
textColorstring'#000'Announcement text color.
isCloseablebooleantrueWhether this announcement can be dismissed with a '×' button.

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    announcementBar: {
      id: 'support_us',
      content:
        'We are looking to revamp our docs, please fill <a target="_blank" rel="noopener noreferrer" href="#">this survey</a>',
      backgroundColor: '#fafbfc',
      textColor: '#091E42',
      isCloseable: false,
    },
  },
};

Accepted fields:

NameTypeDefaultDescription

The logo can be placed in static folder. Logo URL is set to base URL of your site by default. Although you can specify your own URL for the logo, if it is an external link, it will open in a new tab. In addition, you can override a value for the target attribute of logo link, it can come in handy if you are hosting docs website in a subdirectory of your main website, and in which case you probably do not need a link in the logo to the main website will open in a new tab.

To improve dark mode support, you can also set a different logo for this mode.

Accepted fields:

NameTypeDefaultDescription

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      title: 'Site Title',
      logo: {
        alt: 'Site Logo',
        src: 'img/logo.svg',
        srcDark: 'img/logo_dark.svg',
        href: 'https://docusaurus.io/',
        target: '_self',
        width: 32,
        height: 32,
      },
    },
  },
};

You can add items to the navbar via themeConfig.navbar.items.

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          type: 'doc',
          position: 'left',
          docId: 'introduction',
          label: 'Docs',
        },
        {to: 'blog', label: 'Blog', position: 'left'},
        {
          type: 'docsVersionDropdown',
          position: 'right',
        },
        {
          type: 'localeDropdown',
          position: 'right',
        },
        {
          href: 'https://github.com/facebook/docusaurus',
          position: 'right',
          className: 'header-github-link',
          'aria-label': 'GitHub repository',
        },
      ],
    },
  },
};

The items can have different behaviors based on the type field. The sections below will introduce you to all the types of navbar items available.

By default, Navbar items are regular links (internal or external).

React Router should automatically apply active link styling to links, but you can use activeBasePath in edge cases. For cases in which a link should be active on several different paths (such as when you have multiple doc folders under the same sidebar), you can use activeBaseRegex. activeBaseRegex is a more flexible alternative to activeBasePath and takes precedence over it -- Docusaurus parses it into a regular expression that is tested against the current URL.

Outbound (external) links automatically get target="_blank" rel="noopener noreferrer" attributes.

Accepted fields:

NameTypeDefaultDescription
note

In addition to the fields above, you can specify other arbitrary attributes that can be applied to a HTML link.

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          to: 'docs/introduction',
          // Only one of "to" or "href" should be used
          // href: 'https://www.facebook.com',
          label: 'Introduction',
          position: 'left',
          activeBaseRegex: 'docs/(next|v8)',
          target: '_blank',
        },
      ],
    },
  },
};

Navbar items of the type dropdown has the additional items field, an inner array of navbar items.

Navbar dropdown items only accept the following "link-like" item types:

Note that the dropdown base item is a clickable link as well, so this item can receive any of the props of a plain navbar link.

Accepted fields:

NameTypeDefaultDescription

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          type: 'dropdown',
          label: 'Community',
          position: 'left',
          items: [
            {
              label: 'Facebook',
              href: 'https://www.facebook.com',
            },
            {
              type: 'doc',
              label: 'Social',
              docId: 'social',
            },
            // ... more items
          ],
        },
      ],
    },
  },
};

If you want to link to a specific doc, this special navbar item type will render the link to the doc of the provided docId. It will get the class navbar__link--active as long as you browse a doc of the same sidebar.

Accepted fields:

NameTypeDefaultDescription

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          type: 'doc',
          position: 'left',
          docId: 'introduction',
          label: 'Docs',
        },
      ],
    },
  },
};

If you use docs with versioning, this special navbar item type that will render a dropdown with all your site's available versions.

The user will be able to switch from one version to another, while staying on the same doc (as long as the doc id is constant across versions).

Accepted fields:

NameTypeDefaultDescription

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          type: 'docsVersionDropdown',
          position: 'left',
          dropdownItemsAfter: [{to: '/versions', label: 'All versions'}],
          dropdownActiveClassDisabled: true,
        },
      ],
    },
  },
};

If you use docs with versioning, this special navbar item type will link to the active/browsed version of your doc (depends on the current URL), and fallback to the latest version.

Accepted fields:

NameTypeDefaultDescription

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          type: 'docsVersion',
          position: 'left',
          to: '/path',
          label: 'label',
        },
      ],
    },
  },
};

If you use the i18n feature, this special navbar item type will render a dropdown with all your site's available locales.

The user will be able to switch from one locale to another, while staying on the same page.

Accepted fields:

NameTypeDefaultDescription

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          type: 'localeDropdown',
          position: 'left',
          dropdownItemsAfter: [
            {
              to: 'https://my-site.com/help-us-translate',
              label: 'Help us translate',
            },
          ],
        },
      ],
    },
  },
};

If you use the search, the search bar will be the rightmost element in the navbar.

However, with this special navbar item type, you can change the default location.

NameTypeDefaultDescription
docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      items: [
        {
          type: 'search',
          position: 'right',
        },
      ],
    },
  },
};

Auto-hide sticky navbar​

You can enable this cool UI feature that automatically hides the navbar when a user starts scrolling down the page, and show it again when the user scrolls up.

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      hideOnScroll: true,
    },
  },
};

You can set the static Navbar style without disabling the theme switching ability. The selected style will always apply no matter which theme user have selected.

Currently, there are two possible style options: dark and primary (based on the --ifm-color-primary color). You can see the styles preview in the Infima documentation.

docusaurus.config.js
module.exports = {
  themeConfig: {
    navbar: {
      style: 'primary',
    },
  },
};

CodeBlock​

Docusaurus uses Prism React Renderer to highlight code blocks. All configuration are in the prism object.

Accepted fields:

NameTypeDefaultDescription
themePrismThemepalenightThe Prism theme to use for light-theme code blocks.
darkThemePrismThemepalenightThe Prism theme to use for dark-theme code blocks.
defaultLanguagestringundefinedThe side of the navbar this item should appear on.

Theme​

By default, we use Palenight as syntax highlighting theme. You can specify a custom theme from the list of available themes. You may also use a different syntax highlighting theme when the site is in dark mode.

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    prism: {
      theme: require('prism-react-renderer/themes/github'),
      darkTheme: require('prism-react-renderer/themes/dracula'),
    },
  },
};
note

If you use the line highlighting Markdown syntax, you might need to specify a different highlight background color for the dark mode syntax highlighting theme. Refer to the docs for guidance.

Default language​

You can set a default language for code blocks if no language is added after the opening triple backticks (i.e. ```). Note that a valid language name must be passed.

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    prism: {
      defaultLanguage: 'javascript',
    },
  },
};

You can add logo and a copyright to the footer via themeConfig.footer. Logo can be placed in static folder. Logo URL works in the same way of the navbar logo.

Accepted fields:

NameTypeDefaultDescription

Example configuration:

docusaurus.config.js
module.exports = {
  themeConfig: {
    footer: {
      logo: {
        alt: 'Facebook Open Source Logo',
        src: 'img/oss_logo.png',
        href: 'https://opensource.facebook.com',
        width: 160,
        height: 51,
      },
      copyright: `Copyright © ${new Date().getFullYear()} My Project, Inc. Built with Docusaurus.`,

Table of Contents​

You can adjust the default table of contents via themeConfig.tableOfContents.

NameTypeDefaultDescription

    tableOfContents: {
      minHeadingLevel: 2,
      maxHeadingLevel: 5,
    },
  },
};

Hooks​

useThemeContext​

React hook to access theme context. This context contains functions for setting light and dark mode and exposes boolean variable, indicating which mode is currently in use.

Usage example:

import React from 'react';
import useThemeContext from '@theme/hooks/useThemeContext';

const Example = () => {
  const {isDarkTheme, setLightTheme, setDarkTheme} = useThemeContext();

  return <h1>Dark mode is now {isDarkTheme ? 'on' : 'off'}</h1>;
};
note

The component calling useThemeContext must be a child of the Layout component.

function ExamplePage() {
  return (
    <Layout>
      <Example />
    </Layout>
  );
}

i18n​

Read the i18n introduction first.
