# `docusaurus.config.js`
import APITable from '@site/src/components/APITable';
:::info
Refer to the Getting Started [**Configuration**](../configuration.mdx) for examples.
:::
## Overview {#overview}
`docusaurus.config.js` contains configurations for your site and is placed in the root directory of your site.
This file is run in Node.js and should export a site configuration object, or a function that creates it.
The `docusaurus.config.js` file supports:
- [**ES Modules**](https://flaviocopes.com/es-modules/)
- [**CommonJS**](https://flaviocopes.com/commonjs/)
- [**TypeScript**](../typescript-support.mdx#typing-config)
Examples:
```js title="docusaurus.config.js"
export default {
title: 'Docusaurus',
url: 'https://docusaurus.io',
// your site config ...
};
```
```js title="docusaurus.config.js"
export default async function createConfigAsync() {
return {
title: 'Docusaurus',
url: 'https://docusaurus.io',
// your site config ...
};
}
```
:::tip
Refer to [**Syntax to declare `docusaurus.config.js`**](../configuration.mdx#syntax-to-declare-docusaurus-config) for a more exhaustive list of examples and explanations.
:::
## Required fields {#required-fields}
### `title` {#title}
- Type: `string`
Title for your website. Will be used in metadata and as browser tab title.
```js title="docusaurus.config.js"
export default {
title: 'Docusaurus',
};
```
### `url` {#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"
export default {
url: 'https://docusaurus.io',
};
```
### `baseUrl` {#baseUrl}
- Type: `string`
Base URL for your site. Can be considered as the path after the host. For example, `/metro/` is the base URL 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. Always has both leading and trailing slash.
```js title="docusaurus.config.js"
export default {
baseUrl: '/',
};
```
## Optional fields {#optional-fields}
### `favicon` {#favicon}
- Type: `string | undefined`
Path to your site favicon; must be a URL that can be used in link's href. For example, if your favicon is in `static/img/favicon.ico`:
```js title="docusaurus.config.js"
export default {
favicon: '/img/favicon.ico',
};
```
### `trailingSlash` {#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 serves static files differently (this behavior may even change over time).
Refer to the [deployment guide](../deployment.mdx) and [slorber/trailing-slash-guide](https://github.com/slorber/trailing-slash-guide) to choose the appropriate setting.
:::
### `i18n` {#i18n}
- Type: `Object`
The i18n configuration object to [localize your site](../i18n/i18n-introduction.mdx).
Example:
{/* cSpell:ignore فارسی */}
```js title="docusaurus.config.js"
export default {
i18n: {
defaultLocale: 'en',
locales: ['en', 'fa'],
path: 'i18n',
localeConfigs: {
en: {
label: 'English',
direction: 'ltr',
htmlLang: 'en-US',
calendar: 'gregory',
path: 'en',
},
fa: {
label: 'فارسی',
direction: 'rtl',
htmlLang: 'fa-IR',
calendar: 'persian',
path: 'fa',
},
},
},
};
```
- `defaultLocale`: The locale that (1) does not have its name in the base URL (2) gets started with `docusaurus start` without `--locale` option (3) will be used for the `<link hrefLang="x-default">` tag
- `locales`: List of locales deployed on your site. Must contain `defaultLocale`.
- `path`: Root folder which all locale folders are relative to. Can be absolute or relative to the config file. Defaults to `i18n`.
- `localeConfigs`: Individual options for each locale.
- `label`: The label displayed for this locale in the locales dropdown.
- `direction`: `ltr` (default) or `rtl` (for [right-to-left languages](https://developer.mozilla.org/en-US/docs/Glossary/rtl) like Farsi, Arabic, Hebrew, etc.). Used to select the locale's CSS and HTML meta attribute.
- `htmlLang`: BCP 47 language tag to use in `<html lang="...">` (or any other DOM tag name) and in `<link ... hreflang="...">`
- `calendar`: the [calendar](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/Locale/calendar) used to calculate the date era. Note that it doesn't control the actual string displayed: `MM/DD/YYYY` and `DD/MM/YYYY` are both `gregory`. To choose the format (`DD/MM/YYYY` or `MM/DD/YYYY`), set your locale name to `en-GB` or `en-US` (`en` means `en-US`).
- `path`: Root folder that all plugin localization folders of this locale are relative to. Will be resolved against `i18n.path`. Defaults to the locale's name. Note: this has no effect on the locale's `baseUrl`—customization of base URL is a work-in-progress.
### `noIndex` {#noIndex}
- Type: `boolean`
This option adds `<meta name="robots" content="noindex, nofollow">` to every page 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"
export default {
noIndex: true, // Defaults to `false`
};
```
### `onBrokenLinks` {#onBrokenLinks}
- Type: `'ignore' | 'log' | 'warn' | '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.
:::note
The broken links detection is only available for a production build (`docusaurus build`).
:::
### `onBrokenAnchors` {#onBrokenAnchors}
- Type: `'ignore' | 'log' | 'warn' | 'throw'`
The behavior of Docusaurus when it detects any broken anchor declared with the `Heading` component of Docusaurus.
By default, it prints a warning, to let you know about your broken anchors.
### `onBrokenMarkdownLinks` {#onBrokenMarkdownLinks}
- Type: `'ignore' | 'log' | 'warn' | '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.
### `onDuplicateRoutes` {#onDuplicateRoutes}
- Type: `'ignore' | 'log' | 'warn' | 'throw'`
The behavior of Docusaurus when it detects any [duplicate routes](/guides/creating-pages.mdx#duplicate-routes).
By default, it displays a warning after you run `yarn start` or `yarn build`.
### `tagline` {#tagline}
- Type: `string`
The tagline for your website.
```js title="docusaurus.config.js"
export default {
tagline:
'Docusaurus makes it easy to maintain Open Source documentation websites.',

export default {
presets: [],
};
```
### `markdown` {#markdown}
The global Docusaurus Markdown config.
- Type: `MarkdownConfig`
```ts
type MarkdownPreprocessor = (args: {
filePath: string;
fileContent: string;
}) => string;
type MDX1CompatOptions =
| boolean
| {
comments: boolean;
admonitions: boolean;
headingIds: boolean;
};
export type ParseFrontMatter = (params: {
filePath: string;
fileContent: string;
defaultParseFrontMatter: ParseFrontMatter;
}) => Promise<{
frontMatter: {[key: string]: unknown};
content: string;
}>;
type MarkdownConfig = {
format: 'mdx' | 'md' | 'detect';
mermaid: boolean;
preprocessor?: MarkdownPreprocessor;
parseFrontMatter?: ParseFrontMatter;
mdx1Compat: MDX1CompatOptions;
remarkRehypeOptions: object; // see https://github.com/remarkjs/remark-rehype#options
};
```
Example:
```js title="docusaurus.config.js"
export default {
markdown: {
format: 'mdx',
mermaid: true,
preprocessor: ({filePath, fileContent}) => {
return fileContent.replaceAll('{{MY_VAR}}', 'MY_VALUE');
},
parseFrontMatter: async (params) => {
const result = await params.defaultParseFrontMatter(params);
result.frontMatter.description =
result.frontMatter.description?.replaceAll('{{MY_VAR}}', 'MY_VALUE');
return result;
},
mdx1Compat: {
comments: true,
admonitions: true,
headingIds: true,
},
},
};
```
```mdx-code-block
<APITable>
```
| Name | Type | Default | Description |
| --- | --- | --- | --- |
| `format` | `'mdx' \| 'md' \| 'detect'` | `'mdx'` | The default parser format to use for Markdown content. Using 'detect' will select the appropriate format automatically based on file extensions: `.md` vs `.mdx`. |
| `mermaid` | `boolean` | `false` | When `true`, allows Docusaurus to render Markdown code blocks with `mermaid` language as Mermaid diagrams. |
| `preprocessor` | `MarkdownPreprocessor` | `undefined` | Gives you the ability to alter the Markdown content string before parsing. Use it as a last-resort escape hatch or workaround: it is almost always better to implement a Remark/Rehype plugin. |
| `parseFrontMatter` | `ParseFrontMatter` | `undefined` | Gives you the ability to provide your own front matter parser, or to enhance the default parser. Read our [front matter guide](../guides/markdown-features/markdown-features-intro.mdx#front-matter) for details. |
| `mdx1Compat` | `MDX1CompatOptions` | `{comments: true, admonitions: true, headingIds: true}` | Compatibility options to make it easier to upgrade to Docusaurus v3+. |
| `remarkRehypeOptions` | `object` | `undefined` | Makes it possible to pass custom [`remark-rehype` options](https://github.com/remarkjs/remark-rehype#options). |
```mdx-code-block
</APITable>
```
### `customFields` {#customFields}
Docusaurus guards `docusaurus.config.js` from unknown fields. To add a custom field, define it on `customFields`.
- Type: `Object`
```js title="docusaurus.config.js"
export default {
customFields: {
admin: 'endi',
superman: 'lol',
},
};
```
Attempting to add unknown fields in the config will lead to errors during build time:
```bash
Error: The field(s) 'foo', 'bar' are not recognized in docusaurus.config.js
```
### `staticDirectories` {#staticDirectories}
An array of paths, relative to the site's directory or absolute. Files under these paths will be copied to the build output as-is.
- Type: `string[]`
Example:
```js title="docusaurus.config.js"
export default {
staticDirectories: ['static'],
};
```
### `headTags` {#headTags}
An array of tags that will be inserted in the HTML `<head>`. The values must be objects that contain two properties; `tagName` and `attributes`. `tagName` must be a string that determines the tag being created; eg `"link"`. `attributes` must be an attribute-value map.
- Type: `{ tagName: string; attributes: Object; }[]`
Example:
```js title="docusaurus.config.js"
export default {
headTags: [
{
tagName: 'link',
attributes: {
rel: 'icon',
href: '/img/docusaurus.png',
},
},
],
};
```
This would become `<link rel="icon" href="img/docusaurus.png" />` in the generated HTML.
### `scripts` {#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>`. If you use a plain object, the only required attribute is `src`, and any other attributes are permitted (each one should have boolean/string values).
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:
```js title="docusaurus.config.js"
export default {
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,
},
],
};
```
### `stylesheets` {#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>`. If you use an object, the only required attribute is `href`, and any other attributes are permitted (each one should have boolean/string values).
- Type: `(string | Object)[]`
Example:
```js title="docusaurus.config.js"
export default {
stylesheets: [
// String format.
'https://docusaurus.io/style.css',
// Object format.
{
href: 'http://mydomain.com/style.css',
},
],
};
```
:::info
By default, the `<link>` tags will have `rel="stylesheet"`, but you can explicitly add a custom `rel` value to inject any kind of `<link>` tag, not necessarily stylesheets.
:::
### `clientModules` {#clientModules}
An array of [client modules](../advanced/client.mdx#client-modules) to load globally on your site.
Example:
```js title="docusaurus.config.js"
export default {
clientModules: ['./mySiteGlobalJs.js', './mySiteGlobalCss.css'],
};
```
### `ssrTemplate` {#ssrTemplate}
An HTML template written in [Eta's syntax](https://eta.js.org/docs/syntax#syntax-overview) 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:
```js title="docusaurus.config.js"
export default {
ssrTemplate: `<!DOCTYPE html>
<html <%~ it.htmlAttributes %>>
<head>
<meta charset="UTF-8">
<meta name="generator" content="Docusaurus v<%= it.version %>">
<% it.metaAttributes.forEach((metaAttribute) => { %>
<%~ metaAttribute %>
<% }); %>
<%~ it.headTags %>
<% 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>`,
};
```
### `titleDelimiter` {#titleDelimiter}
- Type: `string`
Will be used as title delimiter in the generated `<title>` tag.
Example:
```js title="docusaurus.config.js"
export default {
titleDelimiter: '🦖', // Defaults to `|`
};
```
### `baseUrlIssueBanner` {#baseUrlIssueBanner}
- 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.
Example:
```js title="docusaurus.config.js"
export default {
baseUrlIssueBanner: true, // Defaults to `true`
};
```
![A sample base URL issue banner. The style is very raw since the stylesheets failed to load. The text says "Your Docusaurus site did not load properly... Current configured baseUrl = / (default value); We suggest trying baseUrl = /build/](/img/baseUrlIssueBanner.png)
:::warning
This banner needs to inline CSS / JS in case all asset loading fails due to wrong base URL.
If you have a strict [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP), you should rather disable it.

# 📦 create-docusaurus
A scaffolding utility to help you instantly set up a functional Docusaurus app.
## Usage {#usage}
```bash
npx create-docusaurus@latest [name] [template] [rootDir]
```
The `name` argument will be used as the site's path as well as the `name` field in the created app's package.json. It can be an absolute path, or a path relative to `rootDir`.
The `template` argument can be one of the following:
- `classic`: Uses the classic template (recommended)
- `facebook`: Uses the Facebook/Meta template, which contains some Meta-specific setup
- A git repo URL (beginning with `https://` or `git@`), which can be cloned to the destination
- A local file path relative to CWD, which contains the files to be copied to destination
The `rootDir` will be used to resolve the absolute path to the site directory. The default is CWD.
:::warning
This command should be preferably used in an interactive shell so all features are available.
:::
## Options {#options}
### `-t, --typescript` {#typescript}
Used when the template argument is a recognized name. Currently, only `classic` provides a TypeScript variant.
### `-g, --git-strategy` {#git-strategy}
Used when the template argument is a git repo. It needs to be one of:
- `deep`: preserves full git history
- `shallow`: clones with `--depth=1`
- `copy`: does a shallow clone, but does not create a git repo
- `custom`: enter your custom git clone command. We will prompt you for it. You can write something like `git clone --depth 10`, and we will append the repository URL and destination directory.
### `-p, --package-manager` {#package-manager}
Value should be one of `npm`, `yarn`, `pnpm`, or `bun`. If it's not explicitly provided, Docusaurus will infer one based on:
- The lockfile already present in the CWD (e.g. if you are setting up website in an existing project)
- The command used to invoke `create-docusaurus` (e.g. `npm init`, `npx`, `yarn create`, `bunx`, etc.)
- Interactive prompting, in case all heuristics are not present
### `-s, --skip-install` {#skip-install}
If provided, Docusaurus will not automatically install dependencies after creating the app. The `--package-manager` option is only useful when you are actually installing dependencies.

# 📦 eslint-plugin
[ESLint](https://eslint.org/) is a tool that statically analyzes your code and reports problems or suggests best practices through editor hints and command line. Docusaurus provides an ESLint plugin to enforce best Docusaurus practices.
## Installation
```bash npm2yarn
npm install --save-dev @docusaurus/eslint-plugin
```
## Usage
### Recommended config
Add `plugin:@docusaurus/recommended` to the `extends` section of your `.eslintrc` configuration file:
```json title=".eslintrc"
{
"extends": ["plugin:@docusaurus/recommended"]
}
```
This will enable the `@docusaurus` eslint plugin and use the `recommended` config. See [Supported rules](#supported-rules) below for a list of rules that this will enable.
### Manual config
For more fine-grained control, you can also enable the plugin manually and configure the rules you want to use directly:
```json title=".eslintrc"
{
"plugins": ["@docusaurus"],
"rules": {
"@docusaurus/string-literal-i18n-messages": "error",
"@docusaurus/no-untranslated-text": "warn"
}
}
```
## Supported configs
- Recommended: recommended rule set for most Docusaurus sites that should be extended from.
- All: **all** rules enabled. This will change between minor versions, so you should not use this if you want to avoid unexpected breaking changes.
## Supported rules
| Name | Description | |
| --- | --- | --- |
| [`@docusaurus/no-untranslated-text`](./no-untranslated-text.mdx) | Enforce text labels in JSX to be wrapped by translate calls | |
| [`@docusaurus/string-literal-i18n-messages`](./string-literal-i18n-messages.mdx) | Enforce translate APIs to be called on plain text labels | ✅ |
| [`@docusaurus/no-html-links`](./no-html-links.mdx) | Ensures @docusaurus/Link is used instead of `<a>` tags | ✅ |
| [`@docusaurus/prefer-docusaurus-heading`](./prefer-docusaurus-heading.mdx) | Ensures @theme/Heading is used instead of `<hn>` tags for headings | ✅ |
✅ = recommended
## Example configuration
Here's an example configuration:
```js title=".eslintrc.js"
module.exports = {
extends: ['plugin:@docusaurus/recommended'],
rules: {
'@docusaurus/no-untranslated-text': [
'warn',
{ignoredStrings: ['·', '—', '×']},
],
},
};

# no-html-links
import APITable from '@site/src/components/APITable';
Ensure that the Docusaurus [`<Link>`](../../../docusaurus-core.mdx#link) component is used instead of `<a>` tags.
The `<Link>` component has prefetching and preloading built-in. It also does build-time broken link detection, and helps Docusaurus understand your site's structure better.

# no-untranslated-text
import APITable from '@site/src/components/APITable';
Enforce text labels in JSX to be wrapped by translate calls.
When the [i18n feature](../../../i18n/i18n-introduction.mdx) is used, this rule ensures that all labels appearing on the website are translatable, so no string accidentally slips through untranslated.
## Rule Details {#details}
Examples of **incorrect** code for this rule:

# string-literal-i18n-messages
Enforce translate APIs to be called on plain text labels.
Docusaurus offers the [`docusaurus write-translations`](../../../cli.mdx#docusaurus-write-translations-sitedir) API, which statically extracts the text labels marked as translatable. Dynamic values used in `<Translate>` or `translate()` calls will fail to be extracted. This rule will ensure that all translate calls are statically extractable.
## Rule Details {#details}
Examples of **incorrect** code for this rule:
```js
const text = 'Some text to be translated'
// Invalid <Translate> child
<Translate>{text}</Translate>
// Invalid message attribute
translate({message: text})
```
Examples of **correct** code for this rule:
```js
// Valid <Translate> child
<Translate>Some text to be translated</Translate>
// Valid message attribute
translate({message: 'Some text to be translated'})
// Valid <Translate> child using values object as prop
<Translate values={{firstName: 'Sébastien'}}>
{'Welcome, {firstName}! How are you?'}
</Translate>
// Valid message attribute using values object as second argument
translate({message: 'The logo of site {siteName}'}, {siteName: 'Docusaurus'})
```
## When Not To Use It {#when-not-to-use}
If you're not using the [i18n feature](../../../i18n/i18n-introduction.mdx), you can disable this rule.

# 📦 logger
An encapsulated logger for semantically formatting console messages.
Authors of packages in the Docusaurus ecosystem are encouraged to use this package to provide unified log formats.
## APIs
It exports a single object as default export: `logger`. `logger` has the following properties:
- Some useful colors.
- `red`
- `yellow`
- `green`
- `bold`
- `dim`
- Formatters. These functions all have the signature `(msg: unknown) => string`. Note that their implementations are not guaranteed. You should only care about their semantics.
- `path`: formats a file path.
- `url`: formats a URL.
- `name`: formats an identifier.
- `code`: formats a code snippet.
- `subdue`: subdues the text.
- `num`: formats a number.
- The `interpolate` function. It is a template literal tag. The syntax can be found below.
- Logging functions. All logging functions can both be used as normal functions (similar to the `console.log` family, but only accepts one parameter) or template literal tags.
- `info`: prints information.
- `warn`: prints a warning that should be paid attention to.
- `error`: prints an error (not necessarily halting the program) that signals significant problems.
- `success`: prints a success message.
- The `report` function. It takes a `ReportingSeverity` value (`ignore`, `log`, `warn`, `throw`) and reports a message according to the severity.
:::warning A word on the `error` formatter
Beware that an `error` message, even when it doesn't hang the program, is likely going to cause confusion. When users inspect logs and find an `[ERROR]`, even when the build succeeds, they will assume something is going wrong. Use it sparingly.
Docusaurus only uses `logger.error` when printing messages immediately before throwing an error, or when user has set the reporting severity of `onBrokenLink`, etc. to `"error"`.
In addition, `warn` and `error` will color the **entire** message for better attention. If you are printing large blocks of help text about an error, better use `logger.info`.
:::
### Using the template literal tag
The template literal tag evaluates the template and expressions embedded. `interpolate` returns a new string, while other logging functions prints it. Below is a typical usage:
```js
import logger from '@docusaurus/logger';
logger.info`Hello name=${name}! You have number=${money} dollars. Here are the ${
items.length > 1 ? 'items' : 'item'
} on the shelf: ${items}
To buy anything, enter code=${'buy x'} where code=${'x'} is the item's name; to quit, press code=${'Ctrl + C'}.`;
```
An embedded expression is optionally preceded by a flag in the form `[a-z]+=` (a few lowercase letters, followed by an equals sign, directly preceding the embedded expression). If the expression is not preceded by any flag, it's printed out as-is. Otherwise, it's formatted with one of the formatters:
- `path=`: `path`
- `url=`: `url`
- `name=`: `name`
- `code=`: `code`
- `subdue=`: `subdue`
- `number=`: `num`
If the expression is an array, it's formatted by `` `\n- ${array.join('\n- ')}\n` `` (note it automatically gets a leading line end). Each member is formatted by itself and the bullet is not formatted. So you would see the above message printed as:
![Some text output in the terminal, containing array, code, name, and number formatting](./demo.png)

# Plugin Method References
:::warning
This section is a work in progress. Anchor links or even URLs are not guaranteed to be stable.
:::
Plugin APIs are shared by themes and plugins—themes are loaded just like plugins.
## Plugin module {#plugin-module}
Every plugin is imported as a module. The module is expected to have the following members:
- A **default export**: the constructor function for the plugin.
- **Named exports**: the [static methods](./static-methods.mdx) called before plugins are initialized.
## Plugin constructor {#plugin-constructor}
The plugin module's default export is a constructor function with the signature `(context: LoadContext, options: PluginOptions) => Plugin | Promise<Plugin>`.
### `context` {#context}
`context` is plugin-agnostic, and the same object will be passed into all plugins used for a Docusaurus website. The `context` object contains the following fields:
```ts
type LoadContext = {
siteDir: string;
generatedFilesDir: string;
siteConfig: DocusaurusConfig;
outDir: string;
baseUrl: string;
};
```
### `options` {#options}
`options` are the [second optional parameter when the plugins are used](../../using-plugins.mdx#configuring-plugins). `options` are plugin-specific and are specified by users when they use them in `docusaurus.config.js`. If there's a [`validateOptions`](./static-methods.mdx#validateOptions) function exported, the `options` will be validated and normalized beforehand.
Alternatively, if a preset contains the plugin, the preset will then be in charge of passing the correct options into the plugin. It is up to the individual plugin to define what options it takes.
## Example {#example}
Here's a mental model for a presumptuous plugin implementation.
```js
// A JavaScript function that returns an object.
// `context` is provided by Docusaurus. Example: siteConfig can be accessed from context.
// `opts` is the user-defined options.
export default async function myPlugin(context, opts) {
return {
// A compulsory field used as the namespace for directories to cache
// the intermediate data for each plugin.
// If you're writing your own local plugin, you will want it to
// be unique in order not to potentially conflict with imported plugins.
// A good way will be to add your own project name within.
name: 'docusaurus-my-project-cool-plugin',
async loadContent() {
// The loadContent hook is executed after siteConfig and env has been loaded.
// You can return a JavaScript object that will be passed to contentLoaded hook.
},
async contentLoaded({content, actions}) {
// The contentLoaded hook is done after loadContent hook is done.
// `actions` are set of functional API provided by Docusaurus (e.g. addRoute)
},
async postBuild(props) {
// After docusaurus <build> finish.
},
// TODO
async postStart(props) {
// docusaurus <start> finish
},
// TODO
afterDevServer(app, server) {
// https://webpack.js.org/configuration/dev-server/#devserverbefore
},
// TODO
beforeDevServer(app, server) {
// https://webpack.js.org/configuration/dev-server/#devserverafter
},
configureWebpack(config, isServer, utils, content) {
// Modify internal webpack config. If returned value is an Object, it
// will be merged into the final config using webpack-merge;
// If the returned value is a function, it will receive the config as the 1st argument and an isServer flag as the 2nd argument.
},
getPathsToWatch() {
// Paths to watch.
},
getThemePath() {
// Returns the path to the directory where the theme components can
// be found.
},
getClientModules() {
// Return an array of paths to the modules that are to be imported
// in the client bundle. These modules are imported globally before
// React even renders the initial UI.
},
extendCli(cli) {
// Register an extra command to enhance the CLI of Docusaurus
},
injectHtmlTags({content}) {
// Inject head and/or body HTML tags.
},
async getTranslationFiles({content}) {
// Return translation files
},
translateContent({content, translationFiles}) {
// translate the plugin content here
},
translateThemeConfig({themeConfig, translationFiles}) {
// translate the site themeConfig here
},
async getDefaultCodeTranslationMessages() {
// return default theme translations here
},
};
}
export function validateOptions({options, validate}) {
const validatedOptions = validate(myValidationSchema, options);
return validatedOptions;
}
export function validateThemeConfig({themeConfig, validate}) {
const validatedThemeConfig = validate(myValidationSchema, options);
return validatedThemeConfig;
}

# Extending infrastructure
Docusaurus has some infrastructure like hot reloading, CLI, and swizzling, that can be extended by external plugins.
## `getPathsToWatch()` {#getPathsToWatch}
Specifies the paths to watch for plugins and themes. The paths are watched by the dev server so that the plugin lifecycles are reloaded when contents in the watched paths change. Note that the plugins and themes modules are initially called with `context` and `options` from Node, which you may use to find the necessary directory information about the site.
Use this for files that are consumed server-side, because theme files are automatically watched by Webpack dev server.
Example:
```js title="docusaurus-plugin/src/index.js"
import path from 'path';
export default function (context, options) {
return {
name: 'docusaurus-plugin',
// highlight-start
getPathsToWatch() {
const contentPath = path.resolve(context.siteDir, options.path);
return [`${contentPath}/**/*.{ts,tsx}`];
},
// highlight-end
};
}
```
## `extendCli(cli)` {#extendCli}
Register an extra command to enhance the CLI of Docusaurus. `cli` is a [commander](https://www.npmjs.com/package/commander/v/5.1.0) object.
:::warning
The commander version matters! We use commander v5, and make sure you are referring to the right version documentation for available APIs.
:::
Example:
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'docusaurus-plugin',
// highlight-start
extendCli(cli) {
cli
.command('roll')
.description('Roll a random number between 1 and 1000')
.action(() => {
console.log(Math.floor(Math.random() * 1000 + 1));
});
},
// highlight-end
};
}
```
## `getThemePath()` {#getThemePath}
Returns the path to the directory where the theme components can be found. When your users call `swizzle`, `getThemePath` is called and its returned path is used to find your theme components. Relative paths are resolved against the folder containing the entry point.
For example, your `getThemePath` can be:
```js title="my-theme/src/index.js"
export default function (context, options) {
return {
name: 'my-theme',
// highlight-start
getThemePath() {
return './theme';
},
// highlight-end
};
}
```
## `getTypeScriptThemePath()` {#getTypeScriptThemePath}
Similar to `getThemePath()`, it should return the path to the directory where the source code of TypeScript theme components can be found. This path is purely for swizzling TypeScript theme components, and theme components under this path will **not** be resolved by Webpack. Therefore, it is not a replacement for `getThemePath()`. Typically, you can make the path returned by `getTypeScriptThemePath()` be your source directory, and make the path returned by `getThemePath()` be the compiled JavaScript output.
:::tip
For TypeScript theme authors: you are strongly advised to make your compiled output as human-readable as possible. Only strip type annotations and don't transpile any syntaxes, because they will be handled by Webpack's Babel loader based on the targeted browser versions.
You should also format these files with Prettier. Remember—JS files can and will be directly consumed by your users.
:::
Example:
```js title="my-theme/src/index.js"
export default function (context, options) {
return {
name: 'my-theme',
// highlight-start
getThemePath() {
// Where compiled JavaScript output lives
return '../lib/theme';
},
getTypeScriptThemePath() {
// Where TypeScript source code lives
return '../src/theme';
},
// highlight-end
};
}
```
## `getSwizzleComponentList()` {#getSwizzleComponentList}
**This is a static method, not attached to any plugin instance.**
Returns a list of stable components that are considered safe for swizzling. These components will be swizzlable without `--danger`. All components are considered unstable by default. If an empty array is returned, all components are considered unstable. If `undefined` is returned, all components are considered stable.
```js title="my-theme/src/index.js"
export function getSwizzleComponentList() {
return [
'CodeBlock',
'DocSidebar',
'Footer',
'NotFound',
'SearchBar',
'hooks/useTheme',
'prism-include-languages',
];
}
```

# I18n lifecycles
Plugins use these lifecycles to load i18n-related data.
## `getTranslationFiles({content})` {#getTranslationFiles}
Plugins declare the JSON translation files they want to use.
Returns translation files `{path: string, content: ChromeI18nJSON}`:
- `path`: relative to the plugin localized folder `i18n/[locale]/[pluginName]`. Extension `.json` should be omitted to remain generic.
- `content`: using the Chrome i18n JSON format.
These files will be written by the [`write-translations` CLI](../../cli.mdx#docusaurus-write-translations-sitedir) to the plugin i18n subfolder, and will be read in the appropriate locale before calling [`translateContent()`](#translateContent) and [`translateThemeConfig()`](#translateThemeConfig)
Example:
```js title="my-plugin.js"
export default function (context, options) {
return {
name: 'my-plugin',
// highlight-start
async getTranslationFiles({content}) {
return [
{
path: 'sidebar-labels',
content: {
someSidebarLabel: {
message: 'Some Sidebar Label',
description: 'A label used in my plugin in the sidebar',
},
someLabelFromContent: content.myLabel,
},
},
];
},
// highlight-end
};
}
```
## `translateContent({content,translationFiles})` {#translateContent}
Translate the plugin content, using the localized translation files.
Returns the localized plugin content.
The `contentLoaded()` lifecycle will be called with the localized plugin content returned by `translateContent()`.
Example:
```js title="my-plugin.js"
export default function (context, options) {
return {
name: 'my-plugin',
// highlight-start
translateContent({content, translationFiles}) {
const myTranslationFile = translationFiles.find(
(f) => f.path === 'myTranslationFile',
);
return {
...content,
someContentLabel: myTranslationFile.someContentLabel.message,
};
},
// highlight-end
};
}
```
## `translateThemeConfig({themeConfig,translationFiles})` {#translateThemeConfig}
Translate the site `themeConfig` labels, using the localized translation files.
Returns the localized `themeConfig`.
Example:
```js title="my-plugin.js"
export default function (context, options) {
return {
name: 'my-theme',
// highlight-start
translateThemeConfig({themeConfig, translationFiles}) {
const myTranslationFile = translationFiles.find(
(f) => f.path === 'myTranslationFile',
);
return {
...themeConfig,
someThemeConfigLabel: myTranslationFile.someThemeConfigLabel.message,
};
},
// highlight-end
};
}
```
## `async getDefaultCodeTranslationMessages()` {#getDefaultCodeTranslationMessages}
Themes using the `<Translate>` API can provide default code translation messages.
It should return messages in `Record<string, string>`, where keys are translation IDs and values are messages (without the description) localized using the site's current locale.
Example:
```js title="my-plugin.js"
export default function (context, options) {
return {
name: 'my-theme',
// highlight-start
async getDefaultCodeTranslationMessages() {
return readJsonFile(`${context.i18n.currentLocale}.json`);
},
// highlight-end
};
}

# Lifecycle APIs
During the build, plugins are loaded in parallel to fetch their own contents and render them to routes. Plugins may also configure webpack or post-process the generated files.
## `async loadContent()` {#loadContent}
Plugins should use this lifecycle to fetch from data sources (filesystem, remote API, headless CMS, etc.) or do some server processing. The return value is the content it needs.
For example, this plugin below returns a random integer between 1 and 10 as content.
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'docusaurus-plugin',
// highlight-start
async loadContent() {
return 1 + Math.floor(Math.random() * 10);
},
// highlight-end
};
}
```
## `async contentLoaded({content, actions})` {#contentLoaded}
The data that was loaded in `loadContent` will be consumed in `contentLoaded`. It can be rendered to routes, registered as global data, etc.
### `content` {#content}
`contentLoaded` will be called _after_ `loadContent` is done. The return value of `loadContent()` will be passed to `contentLoaded` as `content`.
### `actions` {#actions}
`actions` contain three functions:
#### `addRoute(config: RouteConfig): void` {#addRoute}
Create a route to add to the website.
```ts
export type RouteConfig = {
/**
* With leading slash. Trailing slash will be normalized by config.
*/
path: string;
/**
* Component used to render this route, a path that the bundler can `require`.
*/
component: string;
/**
* Props. Each entry should be `[propName]: pathToPropModule` (created with
* `createData`)
*/
modules?: RouteModules;
/**
* The route context will wrap the `component`. Use `useRouteContext` to
* retrieve what's declared here. Note that all custom route context declared
* here will be namespaced under {@link RouteContext.data}.
*/
context?: RouteModules;
/**
* Nested routes config, useful for "layout routes" having subroutes.
*/
routes?: RouteConfig[];
/**
* React router config option: `exact` routes would not match subroutes.
*/
exact?: boolean;
/**
* React router config option: `strict` routes are sensitive to the presence
* of a trailing slash.
*/
strict?: boolean;
/**
* Used to sort routes.
* Higher-priority routes will be matched first.
*/
priority?: number;
/**
* Optional route metadata
*/
metadata?: RouteMetadata;
/**
* Extra props; will be available on the client side.
*/
[propName: string]: unknown;
};
/**
* Plugin authors can assign extra metadata to the created routes
* It is only available on the Node.js side, and not sent to the browser
* Optional: plugin authors are encouraged but not required to provide it
*
* Some plugins might use this data to provide additional features.
* This is the case of the sitemap plugin to provide support for "lastmod".
* See also: https://github.com/facebook/docusaurus/pull/9954
*/
export type RouteMetadata = {
/**
* The source code file path that led to the creation of the current route
* In official content plugins, this is usually a Markdown or React file
* This path is expected to be relative to the site directory
*/
sourceFilePath?: string;
/**
* The last updated date of this route
* This is generally read from the Git history of the sourceFilePath
* but can also be provided through other means (usually front matter)
*
* This has notably been introduced for adding "lastmod" support to the
* sitemap plugin, see https://github.com/facebook/docusaurus/pull/9954
*/
lastUpdatedAt?: number;
};
type RouteModules = {
[module: string]: Module | RouteModules | RouteModules[];
};
type Module =
| {
path: string;
__import?: boolean;
query?: ParsedUrlQueryInput;
}
| string;
```
#### `createData(name: string, data: any): Promise<string>` {#createData}
A declarative callback to create static data (generally JSON or string) which can later be provided to your routes as props. Takes the file name and data to be stored, and returns the actual data file's path.
For example, this plugin below creates a `/friends` page which displays `Your friends are: Yangshun, Sebastien`:
```jsx title="website/src/components/Friends.js"
import React from 'react';
export default function FriendsComponent({friends}) {
return <div>Your friends are {friends.join(',')}</div>;
}
```
```js title="docusaurus-friends-plugin/src/index.js"
export default function friendsPlugin(context, options) {
return {
name: 'docusaurus-friends-plugin',
// highlight-start
async contentLoaded({content, actions}) {
const {createData, addRoute} = actions;
// Create friends.json
const friends = ['Yangshun', 'Sebastien'];
const friendsJsonPath = await createData(
'friends.json',
JSON.stringify(friends),
);
// Add the '/friends' routes, and ensure it receives the friends props
addRoute({
path: '/friends',
component: '@site/src/components/Friends.js',
modules: {
// propName -> JSON file path
friends: friendsJsonPath,
},
exact: true,
});
},
// highlight-end
};
}
```
#### `setGlobalData(data: any): void` {#setGlobalData}
This function permits one to create some global plugin data that can be read from any page, including the pages created by other plugins, and your theme layout.
This data becomes accessible to your client-side/theme code through the [`useGlobalData`](../../docusaurus-core.mdx#useGlobalData) and [`usePluginData`](../../docusaurus-core.mdx#usePluginData) hooks.
:::warning
Global data is... global: its size affects the loading time of all pages of your site, so try to keep it small. Prefer `createData` and page-specific data whenever possible.
:::
For example, this plugin below creates a `/friends` page which displays `Your friends are: Yangshun, Sebastien`:
```jsx title="website/src/components/Friends.js"
import React from 'react';
import {usePluginData} from '@docusaurus/useGlobalData';
export default function FriendsComponent() {
const {friends} = usePluginData('docusaurus-friends-plugin');
return <div>Your friends are {friends.join(',')}</div>;
}
```
```js title="docusaurus-friends-plugin/src/index.js"
export default function friendsPlugin(context, options) {
return {
name: 'docusaurus-friends-plugin',
// highlight-start
async contentLoaded({content, actions}) {
const {setGlobalData, addRoute} = actions;
// Create friends global data
setGlobalData({friends: ['Yangshun', 'Sebastien']});
// Add the '/friends' routes
addRoute({
path: '/friends',
component: '@site/src/components/Friends.js',
exact: true,
});
},
// highlight-end
};
}
```
## `configureWebpack(config, isServer, utils, content)` {#configureWebpack}
Modifies the internal webpack config. If the return value is a JavaScript object, it will be merged into the final config using [`webpack-merge`](https://github.com/survivejs/webpack-merge). If it is a function, it will be called and receive `config` as the first argument and an `isServer` flag as the second argument.
:::warning
The API of `configureWebpack` will be modified in the future to accept an object (`configureWebpack({config, isServer, utils, content})`)
:::
### `config` {#config}
`configureWebpack` is called with `config` generated according to client/server build. You may treat this as the base config to be merged with.
### `isServer` {#isServer}
`configureWebpack` will be called both in server build and in client build. The server build receives `true` and the client build receives `false` as `isServer`.
### `utils` {#utils}
`configureWebpack` also receives an util object:
- `getStyleLoaders(isServer: boolean, cssOptions: {[key: string]: any}): Loader[]`
- `getJSLoader(isServer: boolean, cacheOptions?: {}): Loader | null`
You may use them to return your webpack configuration conditionally.
For example, this plugin below modify the webpack config to transpile `.foo` files.
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'custom-docusaurus-plugin',
// highlight-start
configureWebpack(config, isServer, utils) {
const {getJSLoader} = utils;
return {
module: {
rules: [
{
test: /\.foo$/,
use: [getJSLoader(isServer), 'my-custom-webpack-loader'],
},
],
},
};
},
// highlight-end
};
}
```
### `content` {#content-1}
`configureWebpack` will be called both with the content loaded by the plugin.
### Merge strategy {#merge-strategy}
We merge the Webpack configuration parts of plugins into the global Webpack config using [webpack-merge](https://github.com/survivejs/webpack-merge).
It is possible to specify the merge strategy. For example, if you want a webpack rule to be prepended instead of appended:
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'custom-docusaurus-plugin',
configureWebpack(config, isServer, utils) {
return {
// highlight-start
mergeStrategy: {'module.rules': 'prepend'},
module: {rules: [myRuleToPrepend]},
// highlight-end
};
},
};
}
```
Read the [webpack-merge strategy doc](https://github.com/survivejs/webpack-merge#merging-with-strategies) for more details.
### Configuring dev server {#configuring-dev-server}
The dev server can be configured through returning a `devServer` field.
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'custom-docusaurus-plugin',
configureWebpack(config, isServer, utils) {
return {
// highlight-start
devServer: {
open: '/docs', // Opens localhost:3000/docs instead of localhost:3000/
},
// highlight-end
};
},
};
}
```
## `configurePostCss(options)` {#configurePostCss}
Modifies [`postcssOptions` of `postcss-loader`](https://webpack.js.org/loaders/postcss-loader/#postcssoptions) during the generation of the client bundle.
Should return the mutated `postcssOptions`.
By default, `postcssOptions` looks like this:
```js
const postcssOptions = {
ident: 'postcss',
plugins: [require('autoprefixer')],
};
```
Example:
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'docusaurus-plugin',
// highlight-start
configurePostCss(postcssOptions) {
// Appends new PostCSS plugin.
postcssOptions.plugins.push(require('postcss-import'));
return postcssOptions;
},
// highlight-end
};
}
```
## `postBuild(props)` {#postBuild}
Called when a (production) build finishes.
```ts
interface Props {
siteDir: string;
generatedFilesDir: string;
siteConfig: DocusaurusConfig;
outDir: string;
baseUrl: string;
headTags: string;
preBodyTags: string;
postBodyTags: string;
routesPaths: string[];
plugins: Plugin<any>[];
content: Content;
}
```
Example:
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'docusaurus-plugin',
// highlight-start
async postBuild({siteConfig = {}, routesPaths = [], outDir}) {
// Print out to console all the rendered routes.
routesPaths.map((route) => {
console.log(route);
});
},
// highlight-end
};
}
```
## `injectHtmlTags({content})` {#injectHtmlTags}
Inject head and/or body HTML tags to Docusaurus generated HTML.
`injectHtmlTags` will be called both with the content loaded by the plugin.
```ts
function injectHtmlTags(): {
headTags?: HtmlTags;
preBodyTags?: HtmlTags;
postBodyTags?: HtmlTags;
};
type HtmlTags = string | HtmlTagObject | (string | HtmlTagObject)[];
type HtmlTagObject = {
/**
* Attributes of the HTML tag
* E.g. `{'disabled': true, 'value': 'demo', 'rel': 'preconnect'}`
*/
attributes?: {
[attributeName: string]: string | boolean;
};
/**
* The tag name e.g. `div`, `script`, `link`, `meta`
*/
tagName: string;
/**
* The inner HTML
*/
innerHTML?: string;
};
```
Example:
```js title="docusaurus-plugin/src/index.js"
export default function (context, options) {
return {
name: 'docusaurus-plugin',
loadContent: async () => {
return {remoteHeadTags: await fetchHeadTagsFromAPI()};
},
// highlight-start
injectHtmlTags({content}) {
return {
headTags: [
{
tagName: 'link',
attributes: {
rel: 'preconnect',
href: 'https://www.github.com',
},
},
...content.remoteHeadTags,
],
preBodyTags: [
{
tagName: 'script',
attributes: {
charset: 'utf-8',
src: '/noflash.js',
},
},
],
postBodyTags: [`<div> This is post body </div>`],
};
},
// highlight-end
};
}
```
Tags will be added as follows:
- `headTags` will be inserted before the closing `</head>` tag after scripts added by config.
- `preBodyTags` will be inserted after the opening `<body>` tag before any child elements.
- `postBodyTags` will be inserted before the closing `</body>` tag after all child elements.
## `getClientModules()` {#getClientModules}
Returns an array of paths to the [client modules](../../advanced/client.mdx#client-modules) that are to be imported into the client bundle.
As an example, to make your theme load a `customCss` or `customJs` file path from `options` passed in by the user:
```js title="my-theme/src/index.js"
export default function (context, options) {
const {customCss, customJs} = options || {};
return {
name: 'name-of-my-theme',
// highlight-start
getClientModules() {
return [customCss, customJs];
},
// highlight-end
};
}
```

# Static methods
Static methods are not part of the plugin instance—they are attached to the constructor function. These methods are used to validate and normalize the plugin options and theme config, which are then used as constructor parameters to initialize the plugin instance.
## `validateOptions({options, validate})` {#validateOptions}
Returns validated and normalized options for the plugin. This method is called before the plugin is initialized. You must return the options since they will be passed to the plugin during initialization.
### `options` {#options}
`validateOptions` is called with `options` passed to plugin for validation and normalization.
### `validate` {#validate}
`validateOptions` is called with `validate` function which takes a **[Joi](https://www.npmjs.com/package/joi)** schema and options as the arguments, returns validated and normalized options. `validate` will automatically handle error and validation config.
:::tip
[Joi](https://www.npmjs.com/package/joi) is recommended for validation and normalization of options.
To avoid mixing Joi versions, use `import {Joi} from '@docusaurus/utils-validation'`
:::
If you don't use **[Joi](https://www.npmjs.com/package/joi)** for validation you can throw an Error in case of invalid options and return options in case of success.
```js title="my-plugin/src/index.js"
export default function myPlugin(context, options) {
return {
name: 'docusaurus-plugin',
// rest of methods
};
}
// highlight-start
export function validateOptions({options, validate}) {
const validatedOptions = validate(myValidationSchema, options);
return validatedOptions;
}
// highlight-end
```
## `validateThemeConfig({themeConfig, validate})` {#validateThemeConfig}
Return validated and normalized configuration for the theme.
### `themeConfig` {#themeConfig}
`validateThemeConfig` is called with `themeConfig` provided in `docusaurus.config.js` for validation and normalization.
### `validate` {#validate-1}
`validateThemeConfig` is called with `validate` function which takes a **[Joi](https://www.npmjs.com/package/joi)** schema and `themeConfig` as the arguments, returns validated and normalized options. `validate` will automatically handle error and validation config.
:::tip
[Joi](https://www.npmjs.com/package/joi) is recommended for validation and normalization of theme config.
To avoid mixing Joi versions, use `import {Joi} from '@docusaurus/utils-validation'`
:::
If you don't use **[Joi](https://www.npmjs.com/package/joi)** for validation you can throw an Error in case of invalid options.
```js title="my-theme/src/index.js"
export default function myPlugin(context, options) {
return {
name: 'docusaurus-plugin',
// rest of methods
};
}
// highlight-start
export function validateThemeConfig({themeConfig, validate}) {
const validatedThemeConfig = validate(myValidationSchema, options);
return validatedThemeConfig;
}
// highlight-end

# 📦 plugin-client-redirects
import APITable from '@site/src/components/APITable';
Docusaurus Plugin to generate **client-side redirects**.
This plugin will write additional HTML pages to your static site that redirect the user to your existing Docusaurus pages with JavaScript.
:::warning production only
This plugin is always inactive in development and **only active in production** because it works on the build output.
:::
:::warning
It is better to use server-side redirects whenever possible.
Before using this plugin, you should look if your hosting provider doesn't offer this feature.
:::
## Installation {#installation}
```bash npm2yarn
npm install --save @docusaurus/plugin-client-redirects
```
## Configuration {#configuration}
Accepted fields:
```mdx-code-block
<APITable>
```
| Option | Type | Default | Description |
| --- | --- | --- | --- |
| `fromExtensions` | `string[]` | `[]` | The extensions to be removed from the route after redirecting. |
| `toExtensions` | `string[]` | `[]` | The extensions to be appended to the route after redirecting. |
| `redirects` | <code>[RedirectRule](#RedirectRule)[]</code> | `[]` | The list of redirect rules. |
| `createRedirects` | <code>[CreateRedirectsFn](#CreateRedirectsFn)</code> | `undefined` | A callback to create a redirect rule. Docusaurus query this callback against every path it has created, and use its return value to output more paths. |
```mdx-code-block
</APITable>
```
:::note
This plugin will also read the [`siteConfig.onDuplicateRoutes`](../docusaurus.config.js.mdx#onDuplicateRoutes) config to adjust its logging level when multiple files will be emitted to the same location.
:::
### Types {#types}
#### `RedirectRule` {#RedirectRule}
```ts
type RedirectRule = {
to: string;
from: string | string[];
};
```
:::note
The idea of "from" and "to" is central in this plugin. "From" means a path that you want to _create_, i.e. an extra HTML file that will be written; "to" means a path to want to redirect _to_, usually a route that Docusaurus already knows about.
This is why you can have multiple "from" for the same "to": we will create multiple HTML files that all redirect to the same destination. On the other hand, one "from" can never have more than one "to": the written HTML file needs to have a determinate destination.
:::
#### `CreateRedirectsFn` {#CreateRedirectsFn}
```ts
// The parameter `path` is a route that Docusaurus has already created. It can
// be seen as the "to", and your return value is the "from". Returning a falsy
// value will not create any redirect pages for this particular path.
type CreateRedirectsFn = (path: string) => string[] | string | null | undefined;
```
### Example configuration {#ex-config}
Here's an example configuration:
```js title="docusaurus.config.js"
export default {
plugins: [
[
'@docusaurus/plugin-client-redirects',
// highlight-start
{
fromExtensions: ['html', 'htm'], // /myPage.html -> /myPage
toExtensions: ['exe', 'zip'], // /myAsset -> /myAsset.zip (if latter exists)
redirects: [
// /docs/oldDoc -> /docs/newDoc
{
to: '/docs/newDoc',
from: '/docs/oldDoc',
},
// Redirect from multiple old paths to the new path
{
to: '/docs/newDoc2',
from: ['/docs/oldDocFrom2019', '/docs/legacyDocFrom2016'],
},
],
createRedirects(existingPath) {
if (existingPath.includes('/community')) {
// Redirect from /docs/team/X to /community/X and /docs/support/X to /community/X
return [
existingPath.replace('/community', '/docs/team'),
existingPath.replace('/community', '/docs/support'),
];
}
return undefined; // Return a falsy value: no redirect created
},
},
// highlight-end
],
],
};
```

<APITable>
```
| Name | Type | Default | Description |
| --- | --- | --- | --- |
| `path` | `string` | `'docs'` | Path to the docs content directory on the file system, relative to site directory. |
| `editUrl` | <code>string \| [EditUrlFunction](#EditUrlFunction)</code> | `undefined` | Base URL to edit your site. The final URL is computed by `editUrl + relativeDocPath`. Using a function allows more nuanced control for each file. Omitting this variable entirely will disable edit links. |
| `editLocalizedFiles` | `boolean` | `false` | The edit URL will target the localized file, instead of the original unlocalized file. Ignored when `editUrl` is a function. |
| `editCurrentVersion` | `boolean` | `false` | The edit URL will always target the current version doc instead of older versions. Ignored when `editUrl` is a function. |
| `routeBasePath` | `string` | `'docs'` | URL route for the docs section of your site. **DO NOT** include a trailing slash. Use `/` for shipping docs without base path. |
| `tagsBasePath` | `string` | `'tags'` | URL route for the tags list page of your site. It is prepended to the `routeBasePath`. |
| `include` | `string[]` | `['**/*.{md,mdx}']` | Array of glob patterns matching Markdown files to be built, relative to the content path. |
| `exclude` | `string[]` | _See example configuration_ | Array of glob patterns matching Markdown files to be excluded. Serves as refinement based on the `include` option. |
| `sidebarPath` | <code>false \| string</code> | `undefined` | Path to sidebar configuration. Use `false` to disable sidebars, or `undefined` to create a fully autogenerated sidebar. |
| `sidebarCollapsible` | `boolean` | `true` | Whether sidebar categories are collapsible by default. See also [Collapsible categories](/docs/sidebar/items#collapsible-categories) |
| `sidebarCollapsed` | `boolean` | `true` | Whether sidebar categories are collapsed by default. See also [Expanded categories by default](/docs/sidebar/items#expanded-categories-by-default) |
| `sidebarItemsGenerator` | <code>[SidebarGenerator](#SidebarGenerator)</code> | _Omitted_ | Function used to replace the sidebar items of type `'autogenerated'` with real sidebar items (docs, categories, links...). See also [Customize the sidebar items generator](/docs/sidebar/autogenerated#customize-the-sidebar-items-generator) |
| `numberPrefixParser` | <code>boolean \| [PrefixParser](#PrefixParser)</code> | _Omitted_ | Custom parsing logic to extract number prefixes from file names. Use `false` to disable this behavior and leave the docs untouched, and `true` to use the default parser. See also [Using number prefixes](/docs/sidebar/autogenerated#using-number-prefixes) |
| `docsRootComponent` | `string` | `'@theme/DocsRoot'` | Parent component of all the docs plugin pages (including all versions). Stays mounted when navigation between docs pages and versions. |
| `docVersionRootComponent` | `string` | `'@theme/DocVersionLayout'` | Parent component of all docs pages of an individual version (doc pages with sidebars, tags pages). Stays mounted when navigation between pages of that specific version. |
| `docRootComponent` | `string` | `'@theme/DocPage'` | Parent component of all doc pages with sidebars (regular docs pages, category generated index pages). Stays mounted when navigation between such pages. |
| `docItemComponent` | `string` | `'@theme/DocItem'` | Main doc container, with TOC, pagination, etc. |
| `docTagsListComponent` | `string` | `'@theme/DocTagsListPage'` | Root component of the tags list page |
| `docTagDocListComponent` | `string` | `'@theme/DocTagDocListPage'` | Root component of the "docs containing tag X" page. |
| `docCategoryGeneratedIndexComponent` | `string` | `'@theme/DocCategoryGeneratedIndexPage'` | Root component of the generated category index page. |
| `remarkPlugins` | `any[]` | `[]` | Remark plugins passed to MDX. |
| `rehypePlugins` | `any[]` | `[]` | Rehype plugins passed to MDX. |
| `beforeDefaultRemarkPlugins` | `any[]` | `[]` | Custom Remark plugins passed to MDX before the default Docusaurus Remark plugins. |
| `beforeDefaultRehypePlugins` | `any[]` | `[]` | Custom Rehype plugins passed to MDX before the default Docusaurus Rehype plugins. |
| `showLastUpdateAuthor` | `boolean` | `false` | Whether to display the author who last updated the doc. |
| `showLastUpdateTime` | `boolean` | `false` | Whether to display the last date the doc was updated. This requires access to git history during the build, so will not work correctly with shallow clones (a common default for CI systems). With GitHub `actions/checkout`, use`fetch-depth: 0`. |
| `breadcrumbs` | `boolean` | `true` | Enable or disable the breadcrumbs on doc pages. |
| `disableVersioning` | `boolean` | `false` | Explicitly disable versioning even when multiple versions exist. This will make the site only include the current version. Will error if `includeCurrentVersion: false` and `disableVersioning: true`. |
| `includeCurrentVersion` | `boolean` | `true` | Include the current version of your docs. |
| `lastVersion` | `string` | First version in `versions.json` | The version navigated to in priority and displayed by default for docs navbar items. |

# 📦 plugin-debug
```mdx-code-block
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';
```
The debug plugin will display useful debug information at [`http://localhost:3000/__docusaurus/debug`](http://localhost:3000/__docusaurus/debug).
It is mostly useful for plugin authors, that will be able to inspect more easily the content of the `.docusaurus` folder (like the creates routes), but also be able to inspect data structures that are never written to disk, like the plugin data loaded through the `contentLoaded` lifecycle.
:::info
If you use the plugin via the classic preset, the preset will **enable the plugin in development and disable it in production** by default (`debug: undefined`) to avoid exposing potentially sensitive information. You can use `debug: true` to always enable it or `debug: false` to always disable it.
If you use a standalone plugin, you may need to achieve the same effect by checking the environment:
```js title="docusaurus.config.js"
export default {
plugins: [
// highlight-next-line
process.env.NODE_ENV === 'production' && '@docusaurus/plugin-debug',
].filter(Boolean),
};
```
:::
:::note
If you report a bug, we will probably ask you to have this plugin turned on in the production, so that we can inspect your deployment config more easily.
If you don't have any sensitive information, you can keep it on in production [like we do](/__docusaurus/debug).
:::
## Installation {#installation}
```bash npm2yarn
npm install --save @docusaurus/plugin-debug
```
:::tip
If you use the preset `@docusaurus/preset-classic`, you don't need to install this plugin as a dependency.
You can configure this plugin through the [preset options](../../using-plugins.mdx#docusauruspreset-classic).

```js title="docusaurus.config.js"
export default {
presets: [

debug: true, // This will enable the plugin in production
},
],
],
};

import APITable from '@site/src/components/APITable';
The default [Google Analytics](https://developers.google.com/analytics/devguides/collection/analyticsjs/) plugin. It is a JavaScript library for measuring how users interact with your website **in the production build**. If you are using Google Analytics 4 you might need to consider using [plugin-google-gtag](./plugin-google-gtag.mdx) instead.
:::danger Deprecated
This plugin is **deprecated**, and will become useless on July 1, 2023.
Google is [moving away from Universal Analytics](https://blog.google/products/marketingplatform/analytics/prepare-for-future-with-google-analytics-4/).
If you are still using this plugin with a `UA-*` tracking id, you should create a Google Analytics 4 account as soon as possible, and use [`@docusaurus/plugin-google-gtag`](./plugin-google-gtag.mdx) instead of this plugin. More details [here](https://github.com/facebook/docusaurus/issues/7221).

| `size` | `number` | _original size_ | Specify one width you want to use; if the specified size exceeds the original image's width, the latter will be used (i.e. images won't be scaled up) |
| `min` | `number` | | As an alternative to manually specifying `sizes`, you can specify `min`, `max` and `steps`, and the sizes will be generated for you. |
| `max` | `number` | | See `min` above |
| `steps` | `number` | `4` | Configure the number of images generated between `min` and `max` (inclusive) |
| `quality` | `number` | `85` | JPEG compression quality |
| `disableInDev` | `boolean` | `true` | You can test ideal image behavior in dev mode by setting this to `false`. **Tip**: use [network throttling](https://www.browserstack.com/guide/how-to-perform-network-throttling-in-chrome) in your browser to simulate slow networks. |

# 📦 plugin-pwa
Docusaurus Plugin to add PWA support using [Workbox](https://developers.google.com/web/tools/workbox). This plugin generates a [Service Worker](https://developers.google.com/web/fundamentals/primers/service-workers) in production build only, and allows you to create fully PWA-compliant documentation site with offline and installation support.
## Installation {#installation}
```bash npm2yarn
npm install --save @docusaurus/plugin-pwa
```
## Configuration {#configuration}
Create a [PWA manifest](https://web.dev/add-manifest/) at `./static/manifest.json`.
Modify `docusaurus.config.js` with a minimal PWA config, like:
```js title="docusaurus.config.js"
export default {
plugins: [
[
'@docusaurus/plugin-pwa',
{
debug: true,
offlineModeActivationStrategies: [
'appInstalled',
'standalone',
'queryString',
],
pwaHead: [
{
tagName: 'link',
rel: 'icon',
href: '/img/docusaurus.png',
},
{
tagName: 'link',
rel: 'manifest',
href: '/manifest.json', // your PWA manifest
},
{
tagName: 'meta',
name: 'theme-color',
content: 'rgb(37, 194, 160)',
},
],
},
],
],
};
```
## Progressive Web App {#progressive-web-app}
Having a service worker installed is not enough to make your application a PWA. You'll need to at least include a [Web App Manifest](https://developer.mozilla.org/en-US/docs/Web/Manifest) and have the correct tags in `<head>` ([Options > pwaHead](#pwahead)).
After deployment, you can use [Lighthouse](https://developers.google.com/web/tools/lighthouse) to run an audit on your site.
For a more exhaustive list of what it takes for your site to be a PWA, refer to the [PWA Checklist](https://developers.google.com/web/progressive-web-apps/checklist)
## App installation support {#app-installation-support}
If your browser supports it, you should be able to install a Docusaurus site as an app.
![A screen recording of the installation process. A button appears in the address bar of the browser, which displays a dialog asking "install this application?" when clicked. After clicking the "Install" button, a new application is opened in the operating system, opening to the Docusaurus homepage.](/img/pwa_install.gif)
:::note
App installation requires the HTTPS protocol and a valid manifest.
:::
## Offline mode (precaching) {#offline-mode-precaching}
We enable users to browse a Docusaurus site offline, by using service-worker precaching.
The [workbox-precaching](https://developers.google.com/web/tools/workbox/modules/workbox-precaching) page explains the idea:
> One feature of service workers is the ability to save a set of files to the cache when the service worker is installing. This is often referred to as "precaching", since you are caching content ahead of the service worker being used.
>
> The main reason for doing this is that it gives developers control over the cache, meaning they can determine when and how long a file is cached as well as serve it to the browser without going to the network, meaning it can be used to create web apps that work offline.
>
> Workbox takes a lot of the heavy lifting out of precaching by simplifying the API and ensuring assets are downloaded efficiently.
By default, offline mode is enabled when the site is installed as an app. See the `offlineModeActivationStrategies` option for details.
After the site has been precached, the service worker will serve cached responses for later visits. When a new build is deployed along with a new service worker, the new one will begin installing and eventually move to a waiting state. During this waiting state, a reload popup will show and ask the user to reload the page for new content. Until the user either clears the application cache or clicks the `reload` button on the popup, the service worker will continue serving the old content.
:::warning
Offline mode / precaching requires downloading all the static assets of the site ahead of time, and can consume unnecessary bandwidth. It may not be a good idea to activate it for all kind of sites.
:::
## Options {#options}
### `debug` {#debug}
- Type: `boolean`
- Default: `false`
Turn debug mode on:
- Workbox logs
- Additional Docusaurus logs
- Unoptimized SW file output
- Source maps
### `offlineModeActivationStrategies` {#offlinemodeactivationstrategies}
- Type: `('appInstalled' | 'mobile' | 'saveData'| 'queryString' | 'always')[]`
- Default: `['appInstalled', 'queryString', 'standalone']`
Strategies used to turn the offline mode on:
- `appInstalled`: activates for users having installed the site as an app (not 100% reliable)
- `standalone`: activates for users running the app as standalone (often the case once a PWA is installed)
- `queryString`: activates if queryString contains `offlineMode=true` (convenient for PWA debugging)
- `mobile`: activates for mobile users (`width <= 996px`)
- `saveData`: activates for users with `navigator.connection.saveData === true`
- `always`: activates for all users
:::warning
Use this carefully: some users may not like to be forced to use the offline mode.
:::
:::danger
It is not possible to detect if a page is rendered as a PWA in a reliable manner.
The `appinstalled` event has been [removed from the specification](https://github.com/w3c/manifest/pull/836), and the [`navigator.getInstalledRelatedApps()`](https://web.dev/get-installed-related-apps/) API is only supported in recent Chrome versions and require `related_applications` declared in the manifest.
The [`standalone` strategy](https://petelepage.com/blog/2019/07/is-my-pwa-installed/) is a nice fallback to activate the offline mode (at least when running the installed app).
:::
### `injectManifestConfig` {#injectmanifestconfig}
[Workbox options](https://developer.chrome.com/docs/workbox/reference/workbox-build/#type-InjectManifestOptions) to pass to `workbox.injectManifest()`. This gives you control over which assets will be precached, and be available offline.
- Type: `InjectManifestOptions`
- Default: `{}`
```js title="docusaurus.config.js"
export default {
plugins: [
[
'@docusaurus/plugin-pwa',
{
injectManifestConfig: {
manifestTransforms: [
//...
],
modifyURLPrefix: {
//...
},
// We already add regular static assets (HTML, images...) to be available offline
// You can add more files according to your needs
globPatterns: ['**/*.{pdf,docx,xlsx}'],
// ...
},
},
],
],
};
```
### `pwaHead` {#pwahead}
- Type: `({ tagName: string; [attributeName: string]: string })[]`
- Default: `[]`
Array of objects containing `tagName` and key-value pairs for attributes to inject into the `<head>` tag. Technically you can inject any head tag through this, but it's ideally used for tags to make your site PWA compliant. Here's a list of tag to make your app fully compliant:
```js
export default {
plugins: [
[
'@docusaurus/plugin-pwa',
{
pwaHead: [
{
tagName: 'link',
rel: 'icon',
href: '/img/docusaurus.png',
},
{
tagName: 'link',
rel: 'manifest',
href: '/manifest.json',
},
{
tagName: 'meta',
name: 'theme-color',
content: 'rgb(37, 194, 160)',
},
{
tagName: 'meta',
name: 'apple-mobile-web-app-capable',
content: 'yes',
},
{
tagName: 'meta',
name: 'apple-mobile-web-app-status-bar-style',
content: '#000',
},
{
tagName: 'link',
rel: 'apple-touch-icon',
href: '/img/docusaurus.png',
},
{
tagName: 'link',
rel: 'mask-icon',
href: '/img/docusaurus.svg',
color: 'rgb(37, 194, 160)',
},
{
tagName: 'meta',
name: 'msapplication-TileImage',
content: '/img/docusaurus.png',
},
{
tagName: 'meta',
name: 'msapplication-TileColor',
content: '#000',
},
],
},
],
],
};
```
### `swCustom` {#swcustom}
- Type: `string | undefined`
- Default: `undefined`
Useful for additional Workbox rules. You can do whatever a service worker can do here, and use the full power of workbox libraries. The code is transpiled, so you can use modern ES6+ syntax here.
For example, to cache files from external routes:
```js
import {registerRoute} from 'workbox-routing';
import {StaleWhileRevalidate} from 'workbox-strategies';
// default fn export receiving some useful params
export default function swCustom(params) {
const {
debug, // :boolean
offlineMode, // :boolean
} = params;
// Cache responses from external resources
registerRoute((context) => {
return [
/graph\.facebook\.com\/.*\/picture/,
/netlify\.com\/img/,
/avatars1\.githubusercontent/,
].some((regex) => context.url.href.match(regex));
}, new StaleWhileRevalidate());
}
```
The module should have a `default` function export, and receives some params.
### `swRegister` {#swregister}
- Type: `string | false`
- Default: `'docusaurus-plugin-pwa/src/registerSW.js'`
Adds an entry before the Docusaurus app so that registration can happen before the app runs. The default `registerSW.js` file is enough for simple registration.
Passing `false` will disable registration entirely.
## Manifest example {#manifest-example}
The Docusaurus site manifest can serve as an inspiration:
```mdx-code-block
import CodeBlock from '@theme/CodeBlock';
<CodeBlock className="language-json">
{JSON.stringify(require('@site/static/manifest.json'),null,2)}
</CodeBlock>
```
## Customizing reload popup {#customizing-reload-popup}
The `@theme/PwaReloadPopup` component is rendered when a new service worker is waiting to be installed, and we suggest a reload to the user. You can [swizzle](../../swizzling.mdx) this component and implement your own UI. It will receive an `onReload` callback as props, which should be called when the `reload` button is clicked. This will tell the service worker to install the waiting service worker and reload the page.
The default theme includes an implementation for the reload popup and uses [Infima Alerts](https://infima.dev/docs/components/alert).
![A screen recording of the reload process. An alert box shows in the bottom right of the window, saying "New content available". After clicking the "Refresh" button, the page's main heading changes from "Introduction" to "PWA :))".](/img/pwa_reload.gif)
Your component can render `null`, but this is not recommended: users won't have a way to get up-to-date content.
