`docusaurus.config.js`

Overview

docusaurus.config.js contains configurations for your site and is placed in the root directory of your site.

Required fields

`title`

Type: string

Title for your website.

docusaurus.config.js

module.exports = {
  title: 'Docusaurus',
};

`url`

Type: string

URL for your website. This can also be considered the top-level hostname. For example, https://facebook.github.io is the URL of https://facebook.github.io/metro/, and https://docusaurus.io is the URL for https://docusaurus.io. This field is related to the baseUrl field.

docusaurus.config.js

module.exports = {
  url: 'https://docusaurus.io',
};

`baseUrl`

Type: string

Base URL for your site. This can also be considered the path after the host. For example, /metro/ is the baseUrl of https://facebook.github.io/metro/. For URLs that have no path, the baseUrl should be set to /. This field is related to the url field.

docusaurus.config.js

module.exports = {
  baseUrl: '/',
};

Optional fields

`favicon`

Type: string | undefined

Path to your site favicon

Example, if your favicon is in static/img/favicon.ico:

docusaurus.config.js

module.exports = {
  favicon: '/img/favicon.ico',
};

`trailingSlash`

Type: boolean | undefined

Allow to customize the presence/absence of a trailing slash at the end of URLs/links, and how static HTML files are generated:

undefined (default): keeps URLs untouched, and emit /docs/myDoc/index.html for /docs/myDoc.md
true: add trailing slashes to URLs/links, and emit /docs/myDoc/index.html for /docs/myDoc.md
false: remove trailing slashes from URLs/links, and emit /docs/myDoc.html for /docs/myDoc.md

tip

Each static hosting provider serve static files differently (this behavior may even change over time).

Refer to the deployment guide and slorber/trailing-slash-guide to choose the appropriate setting.

`i18n`

Type: Object

The i18n configuration object to localize your site.

Example:

docusaurus.config.js

    localeConfigs: {
      en: {
        label: 'English',
        direction: 'ltr',
      },
      fr: {

      },
    },
  },
};

label: the label to use for this locale
direction: ltr (default) or rtl (for right-to-left languages like Araric, Hebrew, etc.)

`noIndex`

Type: boolean

This option adds <meta name="robots" content="noindex, nofollow"> in pages, to tell search engines to avoid indexing your site (more information here).

module.exports = {
  noIndex: true, // Defaults to `false`
};

`onBrokenLinks`

Type: 'ignore' | 'log' | 'warn' | 'error' | 'throw'

`onBrokenMarkdownLinks`

Type: 'ignore' | 'log' | 'warn' | 'error' | 'throw'

The behavior of Docusaurus, when it detects any broken markdown link.

docusaurus.config.js

module.exports = {
  customFields: {
    admin: 'endi',
    superman: 'lol',

Attempting to add unknown field in the config will lead to error in build time:

Error: The field(s) 'foo', 'bar' are not recognized in docusaurus.config.js

`scripts`

An array of scripts to load. The values can be either strings or plain objects of attribute-value maps. The <script> tags will be inserted in the HTML <head>.

Note that <script> added here are render-blocking so you might want to add async: true/defer: true to the objects.

Type: (string | Object)[]

Example:

docusaurus.config.js

module.exports = {
  scripts: [
    // String format.
    'https://docusaurus.io/script.js',
    // Object format.
    {
      src: 'https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/2.0.0/clipboard.min.js',
      async: true,
    },
  ],
};

`clientModules`

An array of client modules to load globally on your site:

Example:

docusaurus.config.js

  clientModules: [
    require.resolve('./mySiteGlobalJs.js'),

  ],
};

`ssrTemplate`

An HTML template written in Eta's syntax that will be used to render your application. This can be used to set custom attributes on the body tags, additional meta tags, customize the viewport, etc. Please note that Docusaurus will rely on the template to be correctly structured in order to function properly, once you do customize it, you will have to make sure that your template is compliant with the requirements from upstream.

Type: string

Example:

docusaurus.config.js

module.exports = {
  ssrTemplate: `<!DOCTYPE html>
<html <%~ it.htmlAttributes %>>
  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta name="generator" content="Docusaurus v<%= it.version %>">
    <% if (it.noIndex) { %>
      <meta name="robots" content="noindex, nofollow" />
    <% } %>
    <%~ it.headTags %>
    <% it.metaAttributes.forEach((metaAttribute) => { %>
      <%~ metaAttribute %>
    <% }); %>
    <% it.stylesheets.forEach((stylesheet) => { %>
      <link rel="stylesheet" href="<%= it.baseUrl %><%= stylesheet %>" />
    <% }); %>
    <% it.scripts.forEach((script) => { %>
      <link rel="preload" href="<%= it.baseUrl %><%= script %>" as="script">
    <% }); %>
  </head>
  <body <%~ it.bodyAttributes %>>
    <%~ it.preBodyTags %>
    <div id="__docusaurus">
      <%~ it.appHtml %>
    </div>
    <% it.scripts.forEach((script) => { %>
      <script src="<%= it.baseUrl %><%= script %>"></script>
    <% }); %>
    <%~ it.postBodyTags %>
  </body>
</html>`,
};

`stylesheets`

An array of CSS sources to load. The values can be either strings or plain objects of attribute-value maps. The <link> tags will be inserted in the HTML <head>.

Type: (string | Object)[]

Example:

docusaurus.config.js

module.exports = {
  stylesheets: [
    // String format.
    'https://docusaurus.io/style.css',
    // Object format.
    {
      href: 'http://mydomain.com/style.css',
    },
  ],
};

`titleDelimiter`

Type: string

A string that will be used as title delimiter in the generated <title> tag.

module.exports = {
  titleDelimiter: '🦖', // Defaults to `|`

Type: boolean

When enabled, will show a banner in case your site can't load its CSS or JavaScript files, which is a very common issue, often related to a wrong baseUrl in site config.

};

baseUrlIssueBanner
