Version: 2.0.0-beta.10 🚧

Manual migration

This manual migration process should be run after the automated migration process, to complete the missing parts, or debug issues in the migration CLI output.

Project setup

package.json

Scoped package names

In Docusaurus 2, we use scoped package names:

  • docusaurus -> @docusaurus/core

This provides a clear distinction between Docusaurus' official packages and community maintained packages. In another words, all Docusaurus' official packages are namespaced under @docusaurus/.

Meanwhile, the default doc site functionalities provided by Docusaurus 1 are now provided by @docusaurus/preset-classic. Therefore, we need to add this dependency as well:

package.json
{
dependencies: {
- "docusaurus": "^1.x.x",
+ "@docusaurus/core": "^2.0.0-beta.0",
+ "@docusaurus/preset-classic": "^2.0.0-beta.0",
}
}
tip

Please use the most recent Docusaurus 2 version, which you can check out here (using the latest tag).

CLI commands

Meanwhile, CLI commands are renamed to docusaurus <command> (instead of docusaurus-command).

The "scripts" section of your package.json should be updated as follows:

package.json
{
"scripts": {
"start": "docusaurus start",
"build": "docusaurus build",
"swizzle": "docusaurus swizzle",
"deploy": "docusaurus deploy"
// ...
}
}

A typical Docusaurus 2 package.json may look like this:

package.json
{
"scripts": {
"docusaurus": "docusaurus",
"start": "docusaurus start",
"build": "docusaurus build",
"swizzle": "docusaurus swizzle",
"deploy": "docusaurus deploy",
"serve": "docusaurus serve",
"clear": "docusaurus clear"
},
"dependencies": {
"@docusaurus/core": "^2.0.0-beta.0",
"@docusaurus/preset-classic": "^2.0.0-beta.0",
"clsx": "^1.1.1",
"react": "^16.8.4",
"react-dom": "^16.8.4"
},
"browserslist": {
"production": [">0.5%", "not dead", "not op_mini all"],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}

Update references to the build directory

In Docusaurus 1, all the build artifacts are located within website/build/<PROJECT_NAME>.

In Docusaurus 2, it is now moved to just website/build. Make sure that you update your deployment configuration to read the generated files from the correct build directory.

If you are deploying to GitHub pages, make sure to run yarn deploy instead of yarn publish-gh-pages script.

.gitignore

The .gitignore in your website should contain:

.gitignore
# dependencies
/node_modules

# production
/build

# generated files
.docusaurus
.cache-loader

# misc
.DS_Store
.env.local
.env.development.local
.env.test.local
.env.production.local

npm-debug.log*
yarn-debug.log*
yarn-error.log*

README

The D1 website may have an existing README file. You can modify it to reflect the D2 changes, or copy the default Docusaurus v2 README.

Site configurations

docusaurus.config.js

Rename siteConfig.js to docusaurus.config.js.

In Docusaurus 2, we split each functionality (blog, docs, pages) into plugins for modularity. Presets are bundles of plugins and for backward compatibility we built a @docusaurus/preset-classic preset which bundles most of the essential plugins present in Docusaurus 1.

Add the following preset configuration to your docusaurus.config.js.

docusaurus.config.js
module.exports = {
// ...
presets: [
[
'@docusaurus/preset-classic',
{
docs: {
// Docs folder path relative to website dir.
path: '../docs',
// Sidebars file relative to website dir.
sidebarPath: require.resolve('./sidebars.json'),
},
// ...
},
],
],
};

We recommend moving the docs folder into the website folder and that is also the default directory structure in v2. Vercel supports Docusaurus project deployments out-of-the-box if the docs directory is within the website. It is also generally better for the docs to be within the website so that the docs and the rest of the website code are co-located within one website directory.

If you are migrating your Docusaurus v1 website, and there are pending documentation pull requests, you can temporarily keep the /docs folder to its original place, to avoid producing conflicts.

Refer to migration guide below for each field in siteConfig.js.

Updated fields

baseUrl, tagline, title, url, favicon, organizationName, projectName, githubHost, scripts, stylesheets

No actions needed, these configuration fields were not modified.

colors

Deprecated. We wrote a custom CSS framework for Docusaurus 2 called Infima which uses CSS variables for theming. The docs are not quite ready yet and we will update here when it is. To overwrite Infima's CSS variables, create your own CSS file (e.g. ./src/css/custom.css) and import it globally by passing it as an option to @docusaurus/preset-classic:

docusaurus.config.js
module.exports = {
// ...
presets: [
[
'@docusaurus/preset-classic',
{
theme: {
customCss: [require.resolve('./src/css/custom.css')],
},
},
],
],
};

Infima uses 7 shades of each color.

/src/css/custom.css
/**
* You can override the default Infima variables here.
* Note: this is not a complete list of --ifm- variables.
*/
:root {
--ifm-color-primary: #25c2a0;
--ifm-color-primary-dark: rgb(33, 175, 144);
--ifm-color-primary-darker: rgb(31, 165, 136);
--ifm-color-primary-darkest: rgb(26, 136, 112);
--ifm-color-primary-light: rgb(70, 203, 174);
--ifm-color-primary-lighter: rgb(102, 212, 189);
--ifm-color-primary-lightest: rgb(146, 224, 208);
}

We recommend using ColorBox to find the different shades of colors for your chosen primary color.

Alteratively, use the following tool to generate the different shades for your website and copy the variables into src/css/custom.css.

CSS Variable NameHexAdjustment
--ifm-color-primary-lightest#80aaef
--ifm-color-primary-lighter#5a91ea
--ifm-color-primary-light#4e89e8
--ifm-color-primary#3578e50
--ifm-color-primary-dark#1d68e1
--ifm-color-primary-darker#1b62d4
--ifm-color-primary-darkest#1751af

Replace the variables in src/css/custom.css with these new variables.

--ifm-color-primary: #3578e5;
--ifm-color-primary-dark: #1d68e1;
--ifm-color-primary-darker: #1b62d4;
--ifm-color-primary-darkest: #1751af;
--ifm-color-primary-light: #4e89e8;
--ifm-color-primary-lighter: #5a91ea;
--ifm-color-primary-lightest: #80aaef;

Site meta info such as assets, SEO, copyright info are now handled by themes. To customize them, use the themeConfig field in your docusaurus.config.js:

docusaurus.config.js
module.exports = {
// ...
themeConfig: {
footer: {
logo: {
alt: 'Facebook Open Source Logo',
src: 'https://docusaurus.io/img/oss_logo.png',
href: 'https://opensource.facebook.com/',
},
copyright: `Copyright Β© ${new Date().getFullYear()} Facebook, Inc.`, // You can also put own HTML here.
},
image: 'img/docusaurus.png',
// ...
},
};

In Docusaurus 1, header icon and header links were root fields in siteConfig:

siteConfig.js
headerIcon: 'img/docusaurus.svg',
headerLinks: [
{ doc: "doc1", label: "Getting Started" },
{ page: "help", label: "Help" },
{ href: "https://github.com/", label: "GitHub" },
{ blog: true, label: "Blog" },
],

Now, these two fields are both handled by the theme:

docusaurus.config.js
module.exports = {
// ...
themeConfig: {
navbar: {
title: 'Docusaurus',
logo: {
alt: 'Docusaurus Logo',
src: 'img/docusaurus.svg',
},
items: [
{to: 'docs/doc1', label: 'Getting Started', position: 'left'},
{to: 'help', label: 'Help', position: 'left'},
{
href: 'https://github.com/',
label: 'GitHub',
position: 'right',
},
{to: 'blog', label: 'Blog', position: 'left'},
],
},
// ...
},
};

algolia

docusaurus.config.js
module.exports = {
// ...
themeConfig: {
algolia: {
apiKey: '47ecd3b21be71c5822571b9f59e52544',
indexName: 'docusaurus-2',
algoliaOptions: { //... },
},
// ...
},
};
caution

Your Algolia DocSearch v1 config (found here) should be updated for Docusaurus v2 (example).

You can contact the DocSearch team (@shortcuts, @s-pace) for support. They can update it for you and trigger a recrawl of your site to restore the search (otherwise you will have to wait up to 24h for the next scheduled crawl)

blogSidebarCount

Deprecated. Pass it as a blog option to @docusaurus/preset-classic instead:

docusaurus.config.js
module.exports = {
// ...
presets: [
[
'@docusaurus/preset-classic',
{
blog: {
postsPerPage: 10,
},
// ...
},
],
],
};

cname

Deprecated. Create a CNAME file in your static folder instead with your custom domain. Files in the static folder will be copied into the root of the build folder during execution of the build command.

customDocsPath, docsUrl, editUrl, enableUpdateBy, enableUpdateTime

BREAKING: editUrl should point to (website) Docusaurus project instead of docs directory.

Deprecated. Pass it as an option to @docusaurus/preset-classic docs instead:

docusaurus.config.js
module.exports = {
// ...
presets: [
[
'@docusaurus/preset-classic',
{
docs: {
// Equivalent to `customDocsPath`.
path: 'docs',
// Equivalent to `editUrl` but should point to `website` dir instead of `website/docs`.
editUrl: 'https://github.com/facebook/docusaurus/edit/main/website',
// Equivalent to `docsUrl`.
routeBasePath: 'docs',
// Remark and Rehype plugins passed to MDX. Replaces `markdownOptions` and `markdownPlugins`.
remarkPlugins: [],
rehypePlugins: [],
// Equivalent to `enableUpdateBy`.
showLastUpdateAuthor: true,
// Equivalent to `enableUpdateTime`.
showLastUpdateTime: true,
},
// ...
},
],
],
};

gaTrackingId

docusaurus.config.js
module.exports = {
// ...
themeConfig: {
googleAnalytics: {
trackingID: 'UA-141789564-1',
},
// ...
},
};

gaGtag

docusaurus.config.js
module.exports = {
// ...
themeConfig: {
gtag: {
trackingID: 'UA-141789564-1',
},
// ...
},
};

Removed fields

The following fields are all deprecated, you may remove from your configuration file.

  • blogSidebarTitle
  • cleanUrl - Clean URL is used by default now.
  • defaultVersionShown - Versioning is not ported yet. You'd be unable to migration to Docusaurus 2 if you are using versioning. Stay tuned.
  • disableHeaderTitle
  • disableTitleTagline
  • docsSideNavCollapsible is available at docsPluginOptions.sidebarCollapsible, and this is turned on by default now.
  • facebookAppId
  • facebookComments
  • facebookPixelId
  • fonts
  • highlight - We now use Prism instead of highlight.js.
  • markdownOptions - We use MDX in v2 instead of Remarkable. Your markdown options have to be converted to Remark/Rehype plugins.
  • markdownPlugins - We use MDX in v2 instead of Remarkable. Your markdown plugins have to be converted to Remark/Rehype plugins.
  • manifest
  • onPageNav - This is turned on by default now.
  • separateCss - It can imported in the same manner as custom.css mentioned above.
  • scrollToTop
  • scrollToTopOptions
  • translationRecruitingLink
  • twitter
  • twitterUsername
  • useEnglishUrl
  • users
  • usePrism - We now use Prism instead of highlight.js
  • wrapPagesHTML

We intend to implement many of the deprecated config fields as plugins in future. Help will be appreciated!

Urls

In v1, all pages were available with or without the .html extension.

For example, these 2 pages exist:

If cleanUrl was:

  • true: links would target /installation
  • false: links would target /installation.html

In v2, by default, the canonical page is /installation, and not /installation.html.

If you had cleanUrl: false in v1, it's possible that people published links to /installation.html.

For SEO reasons, and avoiding breaking links, you should configure server-side redirect rules on your hosting provider.

As an escape hatch, you could use @docusaurus/plugin-client-redirects to create client-side redirects from /installation.html to /installation.

module.exports = {
plugins: [
[
'@docusaurus/plugin-client-redirects',
{
fromExtensions: ['html'],
},
],
],
};

If you want to keep the .html extension as the canonical url of a page, docs can declare a slug: installation.html frontmatter.

Components

In previous version, nested sidebar category is not allowed and sidebar category can only contain doc id. However, v2 allows infinite nested sidebar and we have many types of Sidebar Item other than document.

You'll have to migrate your sidebar if it contains category type. Rename subcategory to category and ids to items.

sidebars.json
{
- type: 'subcategory',
+ type: 'category',
label: 'My Example Subcategory',
+ items: ['doc1'],
- ids: ['doc1']
},

website/core/Footer.js is no longer needed. If you want to modify the default footer provided by Docusaurus, swizzle it:

npm run swizzle @docusaurus/theme-classic Footer

This will copy the current <Footer /> component used by the theme to a src/theme/Footer directory under the root of your site, you may then edit this component for customization.

Do not swizzle the Footer just to add the logo on the left. The logo is intentionally removed in v2 and moved to the bottom. Just configure the footer in docusaurus.config.js with themeConfig.footer:

module.exports = {
themeConfig: {
footer: {
logo: {
alt: 'Facebook Open Source Logo',
src: 'img/oss_logo.png',
href: 'https://opensource.facebook.com',
},
},
},
};

Pages

Please refer to creating pages to learn how Docusaurus 2 pages work. After reading that, notice that you have to move pages/en files in v1 to src/pages instead.

In Docusaurus v1, pages received the siteConfig object as props.

In Docusaurus v2, get the siteConfig object from useDocusaurusContext instead.

In v2, you have to apply the theme layout around each page. The Layout component takes metadata props.

CompLibrary is deprecated in v2, so you have to write your own React component or use Infima styles (Docs will be available soon, sorry about that! In the meanwhile, inspect the V2 website or view https://infima.dev/ to see what styles are available).

You can migrate CommonJS to ES6 imports/exports.

Here's a typical Docusaurus v2 page:

import React from 'react';
import Link from '@docusaurus/Link';
import useDocusaurusContext from '@docusaurus/useDocusaurusContext';
import Layout from '@theme/Layout';

const MyPage = () => {
const {siteConfig} = useDocusaurusContext();
return (
<Layout title={siteConfig.title} description={siteConfig.tagline}>
<div className="hero text--center">
<div className="container ">
<div className="padding-vert--md">
<h1 className="hero__title">{siteConfig.title}</h1>
<p className="hero__subtitle">{siteConfig.tagline}</p>
</div>
<div>
<Link
to="/docs/get-started"
className="button button--lg button--outline button--primary">
Get started
</Link>
</div>
</div>
</div>
</Layout>
);
};

export default MyPage;

The following code could be helpful for migration of various pages:

Content

Replace AUTOGENERATED_TABLE_OF_CONTENTS

This feature is replaced by inline table of content

Update Markdown syntax to be MDX-compatible

In Docusaurus 2, the markdown syntax has been changed to MDX. Hence there might be some broken syntax in the existing docs which you would have to update. A common example is self-closing tags like <img> and <br> which are valid in HTML would have to be explicitly closed now ( <img/> and <br/>). All tags in MDX documents have to be valid JSX.

Frontmatter is parsed by gray-matter. If your frontmatter use special characters like :, you now need to quote it: title: Part 1: my part1 title -> title: Part 1: "my part1 title".

Tips: You might want to use some online tools like HTML to JSX to make the migration easier.

Language-specific code tabs

Refer to the multi-language support code blocks section.

Front matter

The Docusaurus front matter fields for the blog have been changed from camelCase to snake_case to be consistent with the docs.

The fields authorFBID and authorTwitter have been deprecated. They are only used for generating the profile image of the author which can be done via the authors field.

Deployment

The CNAME file used by GitHub Pages is not generated anymore, so be sure you have created it in /static/CNAME if you use a custom domain.

The blog RSS feed is now hosted at /blog/rss.xml instead of /blog/feed.xml. You may want to configure server-side redirects so that users' subscriptions keep working.

Test your site

After migration, your folder structure should look like this:

my-project
β”œβ”€β”€ docs
└── website
β”œβ”€β”€ blog
β”œβ”€β”€ src
β”‚ β”œβ”€β”€ css
β”‚ β”‚ └── custom.css
β”‚ └── pages
β”‚ └── index.js
β”œβ”€β”€ package.json
β”œβ”€β”€ sidebars.json
β”œβ”€β”€ .gitignore
β”œβ”€β”€ docusaurus.config.js
└── static

Start the development server and fix any errors:

cd website
yarn start

You can also try to build the site for production:

yarn build
