+description: API reference for Docusaurus configuration file.
+slug: /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.
+
+```js title="docusaurus.config.js"
+module.exports = {
+ title: 'Docusaurus',
+};
+```
+
+### `favicon`
+
+- Type: `string`
+
+URL for site favicon. Example:
+
+```js title="docusaurus.config.js"
+module.exports = {
+ favicon: 'https://v2.docusaurus.io/favicon.ico',
+};
+```
+
+You can also use the favicon URL relative to the `static` directory of your site. For example, your site has the following directory structure:
+
+```bash
+.
+├── README.md
+├ # ... other files in root directory
+└─ static
+ └── img
+ └── favicon.ico
+```
+
+So you can refer it like below:
+
+```js title="docusaurus.config.js"
+module.exports = {
+ favicon: 'img/favicon.ico',
+};
+```
+
+### `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](#baseurl) field.
+
+```js title="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](#url) field.
+
+```js title="docusaurus.config.js"
+module.exports = {
+ baseUrl: '/',
+};
+```
+
+## Optional fields
+
+### `noIndex`
+
+- Type: `boolean`
+
+This option adds `` in pages, to tell search engines to avoid indexing your site (more information [here](https://moz.com/learn/seo/robots-meta-directives)).
+
+Example:
+
+```js title="docusaurus.config.js"
+module.exports = {
+ noIndex: true, // Defaults to `false`
+};
+```
+
+### `onBrokenLinks`
+
+- Type: `'ignore' | 'log' | 'warn' | 'error' | 'throw'`
+
+The behavior of Docusaurus, when it detects any broken link.
+
+By default, it throws an error, to ensure you never ship any broken link, but you can lower this security if needed.
+
+:::note
+
+The broken links detection is only available for a production build (`docusaurus build`).
+
+:::
+
+### `onBrokenMarkdownLinks`
+
+- Type: `'ignore' | 'log' | 'warn' | 'error' | 'throw'`
+
+The behavior of Docusaurus, when it detects any broken markdown link.
+
+By default, it prints a warning, to let you know about your broken markdown link, but you can change this security if needed.
+
+### `onDuplicateRoutes`
+
+- Type: `'ignore' | 'log' | 'warn' | 'error' | 'throw'`
+
+The behavior of Docusaurus when it detects any [duplicate routes](/guides/creating-pages.md#duplicate-routes).
+
+By default, it displays a warning after you run `yarn start` or `yarn build`.
+
+### `tagline`
+
+- Type: `string`
+
+The tagline for your website.
+
+```js title="docusaurus.config.js"
+module.exports = {
+ tagline:
+ 'Docusaurus makes it easy to maintain Open Source documentation websites.',
+};
+```
+
+### `organizationName`
+
+- Type: `string`
+
+The GitHub user or organization that owns the repository. Used by the deployment command.
+
+```js title="docusaurus.config.js"
+module.exports = {
+ // Docusaurus' organization is facebook
+ organizationName: 'facebook',
+};
+```
+
+### `projectName`
+
+- Type: `string`
+
+The name of the GitHub repository. Used by the deployment command.
+
+```js title="docusaurus.config.js"

+
+### `themeConfig`
+
+- Type: `Object`
+
+
+
+An object containing data needed by the theme you use.

+For Docusaurus' default theme _classic_, we use `themeConfig` to customize your navbar and footer links:

+module.exports = {
+ themeConfig: {
+ colorMode: {
+ defaultMode: 'light',
+ disableSwitch: false,
+ respectPrefersColorScheme: true,
+ switchConfig: {
+ darkIcon: '🌙',
+ lightIcon: '\u2600',
+ // React inline style object
+ // see https://reactjs.org/docs/dom-elements.html#style
+ darkIconStyle: {
+ marginLeft: '2px',
+ },
+ lightIconStyle: {
+ marginLeft: '1px',
+ },
+ },
+ },
+ navbar: {
+ title: 'Site Title',
+ logo: {
+ alt: 'Site Logo',
+ src: 'img/logo.svg',
+ },
+ items: [
+ {
+ to: 'docs/docusaurus.config.js',
+ activeBasePath: 'docs',
+ label: 'docusaurus.config.js',
+ position: 'left',
+ },
+ // ... other links
+ ],
+ },
+ footer: {
+ style: 'dark',
+ links: [
+ {
+ title: 'Docs',
+ items: [
+ {
+ label: 'Docs',
+ to: 'docs/doc1',
+ },
+ ],
+ },
+ // ... other links
+ ],
+ logo: {
+ alt: 'Facebook Open Source Logo',
+ src: 'https://docusaurus.io/img/oss_logo.png',
+ },
+ copyright: `Copyright © ${new Date().getFullYear()} Facebook, Inc.`, // You can also put own HTML here
+ },
+ },
+};
+```
+

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