Version: (fr) 2.0.0-alpha.69

Migrating from v1 to v2

caution

For v1 translated sites, the migration doc is not available yet.

This doc guides you through migrating an existing Docusaurus 1 site to Docusaurus 2.

Your Docusaurus 1 site should have the following structure:

β”œβ”€β”€ docs
└── website
β”œβ”€β”€ blog
β”œβ”€β”€ core
β”‚ └── Footer.js
β”œβ”€β”€ package.json
β”œβ”€β”€ pages
β”œβ”€β”€ sidebars.json
β”œβ”€β”€ siteConfig.js
└── static

After the migration, your Docusaurus 2 site could look like:

website
β”œβ”€β”€ blog
β”œβ”€β”€ docs
β”œβ”€β”€ src
β”‚ β”œβ”€β”€ components
β”‚ β”œβ”€β”€ css
β”‚ └── pages
β”œβ”€β”€ static
β”œβ”€β”€ package.json
β”œβ”€β”€ sidebars.json
β”œβ”€β”€ docusaurus.config.js
tip

You can use the migration command to take care of some of the migration chores.

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-alpha.48",
+ "@docusaurus/preset-classic": "^2.0.0-alpha.48",
}
}
tip

Please use the most recent Docusaurus 2 alpha version, which you can check out here (it's tagged next).

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-alpha.66",
"@docusaurus/preset-classic": "^2.0.0-alpha.66",
"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. Now 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;

footerIcon, copyright, ogImage, twitterImage, docsSideNavCollapsible#

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',
// Equivalent to `docsSideNavCollapsible`.
sidebarCollapsible: false,
// ...
},
};

headerIcon, headerLinks#

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: { //... },
},
// ...
},
};

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/master/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 themeConfig.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#

Sidebar#

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']
},

Footer#

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 (permalink is important, as it defines the canonical url of your page).

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://facebookincubator.github.io/infima/ 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 useBaseUrl from '@docusaurus/useBaseUrl';
import Layout from '@theme/Layout';
const MyPage = () => {
const {siteConfig} = useDocusaurusContext();
return (
<Layout
permalink="/"
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={useBaseUrl('/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#

Remove AUTOGENERATED_TABLE_OF_CONTENTS#

This feature is deprecated. You may read more about it in this issue. If you need the feature, use remark-toc instead and pass it to docs plugin's remarkPlugins option.

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 author_image_url field.

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

Migration command#

The migration command automatically migrates your v1 website to a v2 website.

The migration command migrates:

  • Site configurations (from siteConfig.js to docusaurus.config.js)
  • package.json
  • sidebars.json
  • /docs
  • /blog
  • /static
  • versioned_sidebar.json and /versioned_docs if your site uses versioning
info

Manual tweaking is still required after using the migration command. You still need to migrate your footer, pages and content.

To use the migration command, follow these steps:

  1. Before using the migration command, ensure that /docs, /blog, /static, sidebars.json, siteConfig.js, package.json follow the structure shown at the start of this page.

  2. To migrate your v1 website, run the migration command with the appropriate filesystem paths:

# migration command format
npx @docusaurus/migrate migrate <v1 website directory> <desired v2 website directory>
# example
npx @docusaurus/migrate migrate ./v1-website ./v2-website
  1. To view your new website locally, go into your v2 website's directory and start your development server.
cd ./v2-website
yarn install
yarn start

Options#

You can add option flags to the migration command to automatically migrate Markdown content and pages to v2. It is likely that you will still need to make some manual changes to achieve your desired result.

NameDescription
--mdxAdd this flag to convert Markdown to MDX automatically
--pageAdd this flag to migrate pages automatically
# example using options
npx docusaurus-migrate migrate --mdx --page ./v1-website ./v2-website
danger

The migration of pages and MDX is still a work in progress.

We recommend you to try to run the pages without these options, commit, and then try to run the migration again with the --page and --mdx options.

This way, you'd be able to easily inspect and fix the diff.

Example migration PRs#

You might want to refer to our migration PRs for Create React App and Flux as examples of how a migration for a basic Docusaurus v1 site can be done.

Support#

For any questions, you can ask in the #docusaurus-1-to-2-migration Discord channel. Feel free to tag @yangshun in any migration PRs if you would like us to have a look.


Versioned Site#

Read up https://v2.docusaurus.io/blog/2018/09/11/Towards-Docusaurus-2#versioning first for problems in v1's approach.

Migrate your versioned_docs front matter#

Unlike v1, The markdown header for each versioned doc is no longer altered by using version-${version}-${original_id} as the value for the actual id field. See scenario below for better explanation.

For example, if you have a docs/hello.md.

---
id: hello
title: Hello, World !
---
Hi, Endilie here :)

When you cut a new version 1.0.0, in Docusaurus v1, website/versioned_docs/version-1.0.0/hello.md looks like this:

---
id: version-1.0.0-hello
title: Hello, World !
original_id: hello
---
Hi, Endilie here :)

In comparison, Docusaurus 2 website/versioned_docs/version-1.0.0/hello.md looks like this (exactly same as original)

---
id: hello
title: Hello, World !
---
Hi, Endilie here :)

Since we're going for snapshot and allow people to move (and edit) docs easily inside version. The id frontmatter is no longer altered and will remain the same. Internally, it is set as version-${version}/${id}.

Essentially, here are the necessary changes in each versioned_docs file:

---
- id: version-1.0.0-hello
+ id: hello
title: Hello, World !
- original_id: hello
---
Hi, Endilie here :)

Migrate your versioned_sidebars#

  • Refer to versioned_docs id as version-${version}/${id} (v2) instead of version-${version}-${original_id} (v1).

Because in v1 there is a good chance someone created a new file with front matter id "version-${version}-${id}" that can conflict with versioned_docs id.

For example, Docusaurus 1 can't differentiate docs/xxx.md

---
id: version-1.0.0-hello
---
Another content

vs website/versioned_docs/version-1.0.0/hello.md

---
id: version-1.0.0-hello
title: Hello, World !
original_id: hello
---
Hi, Endilie here :)

Since we don't allow / in v1 & v2 for frontmatter, conflicts are less likely to occur.

So v1 users need to migrate their versioned_sidebars file

Example versioned_sidebars/version-1.0.0-sidebars.json:

versioned_sidebars/version-1.0.0-sidebars.json
{
+ "version-1.0.0/docs": {
- "version-1.0.0-docs": {
"Test": [
+ "version-1.0.0/foo/bar",
- "version-1.0.0-foo/bar",
],
"Guides": [
+ "version-1.0.0/hello",
- "version-1.0.0-hello"
]
}
}

Populate your versioned_sidebars and versioned_docs#

In v2, we use snapshot approach for documentation versioning. Every versioned docs does not depends on other version. It is possible to have foo.md in version-1.0.0 but it doesn't exist in version-1.2.0. This is not possible in previous version due to Docusaurus v1 fallback functionality (https://docusaurus.io/docs/en/versioning#fallback-functionality).

For example, if your versions.json looks like this in v1

versions.json
["1.1.0", "1.0.0"]

Docusaurus v1 creates versioned docs if and only if the doc content is different. Your docs structure might look like this if the only doc changed from v1.0.0 to v1.1.0 is hello.md.

website
β”œβ”€β”€ versioned_docs
β”‚ β”œβ”€β”€ version-1.1.0
β”‚ β”‚ └── hello.md
β”‚ └── version-1.0.0
β”‚ β”œβ”€β”€ foo
β”‚ β”‚ └── bar.md
β”‚ └── hello.md
β”œβ”€β”€ versioned_sidebars
β”‚ └── version-1.0.0-sidebars.json

In v2, you have to populate the missing versioned_docs and versioned_sidebars (with the right frontmatter and id reference too).

website
β”œβ”€β”€ versioned_docs
β”‚ β”œβ”€β”€ version-1.1.0
β”‚ β”‚ β”œβ”€β”€ foo
β”‚ β”‚ β”‚ └── bar.md
β”‚ β”‚ └── hello.md
β”‚ └── version-1.0.0
β”‚ β”œβ”€β”€ foo
β”‚ β”‚ └── bar.md
β”‚ └── hello.md
β”œβ”€β”€ versioned_sidebars
β”‚ β”œβ”€β”€ version-1.1.0-sidebars.json
β”‚ └── version-1.0.0-sidebars.json

Convert style attributes to style objects in MDX#

Docusaurus 2 uses JSX for doc files. If you have any style attributes in your Docusaurus 1 docs, convert them to style objects, like this:

---
id: demo
title: Demo
---
## Section
hello world
- pre style="background: black">zzz</pre>
+ pre style={{background: 'black'}}>zzz</pre>

Translated Site#

We don't provide yet a migration path for v1 translated sites.

v2 i18n support is a work in progress, and will be added before the end of 2020 with a migration guide to help you migrate from v1 + Crowdin to v2 + Crowdin.
