CLI

Docusaurus provides a set of scripts to help you generate, serve, and deploy your website.

Once your website is bootstrapped, the website source will contain the Docusaurus scripts that you can invoke with your package manager:

package.json

{
  // ...
  "scripts": {
    "docusaurus": "docusaurus",
    "start": "docusaurus start",
    "build": "docusaurus build",
    "swizzle": "docusaurus swizzle",
    "deploy": "docusaurus deploy",
    "clear": "docusaurus clear",
    "serve": "docusaurus serve",
    "write-translations": "docusaurus write-translations",
    "write-heading-ids": "docusaurus write-heading-ids"
  }
}

Docusaurus CLI commands

Below is a list of Docusaurus CLI commands and their usages:

docusaurus start [siteDir]

Builds and serves a preview of your site locally with Webpack Dev Server.

Options

Name	Default	Description
--port	3000	Specifies the port of the dev server.
--host	localhost	Specify a host to use. For example, if you want your server to be accessible externally, you can use --host 0.0.0.0.
--locale		Specify site locale to be used.
--hot-only	false	Enables Hot Module Replacement without page refresh as a fallback in case of build failures. More information here.
--no-open	false	Do not open the page automatically in the browser.
--config	undefined	Path to Docusaurus config file, default to [siteDir]/docusaurus.config.js
--poll [optionalIntervalMs]	false	Use polling of files rather than watching for live reload as a fallback in environments where watching doesn't work. More information here.
--no-minify	false	Build website without minimizing JS/CSS bundles.

info

Please note that some functionality (for example, anchor links) will not work in development. The functionality will work as expected in production.

Development over network

When forwarding port 3000 from a remote server or VM (e.g. GitHub Codespaces), you can run the dev server on 0.0.0.0 to make it listen on the local IP.

npm

npm run start -- --host 0.0.0.0

Yarn

yarn run start --host 0.0.0.0

pnpm

pnpm run start --host 0.0.0.0

Bun

bun run start --host 0.0.0.0

Enabling HTTPS

There are multiple ways to obtain a certificate. We will use mkcert as an example.

1. Run mkcert localhost to generate localhost.pem + localhost-key.pem

2. Run mkcert -install to install the cert in your trust store, and restart your browser

3. Start the app with Docusaurus HTTPS env variables:

HTTPS=true SSL_CRT_FILE=localhost.pem SSL_KEY_FILE=localhost-key.pem yarn start

4. Open https://localhost:3000/

docusaurus build [siteDir]

Compiles your site for production.

Options

Name	Default	Description
--dev		Builds the website in dev mode, including full React error messages.
--bundle-analyzer	false	Analyze your bundle with the webpack bundle analyzer.
--out-dir	build	The full path for the new output directory, relative to the current workspace.
--config	undefined	Path to Docusaurus config file, default to [siteDir]/docusaurus.config.js
--locale		Build the site in the specified locale(s). If not specified, all known locales are built.
--no-minify	false	Build website without minimizing JS/CSS bundles.

info

For advanced minification of CSS bundle, we use the advanced cssnano preset (along with additional several PostCSS plugins) and level 2 optimization of clean-css. If as a result of this advanced CSS minification you find broken CSS, build your website with the environment variable USE_SIMPLE_CSS_MINIFIER=true to minify CSS with the default cssnano preset. Please fill out an issue if you experience CSS minification bugs.

You can skip the HTML minification with the environment variable SKIP_HTML_MINIFICATION=true.

docusaurus swizzle [themeName] [componentName] [siteDir]

Swizzle a theme component to customize it.

npm

npm run swizzle [themeName] [componentName
