Today we are extremely happy to finally announce Docusaurus 2.0! 🥳️

At Meta Open Source, we believe Docusaurus will help you build the best documentation websites with minimal effort, letting you focus on what really matters: writing the content.

After 4 years of work, 75 alphas and 22 betas, the next generation of Docusaurus is ready for prime time. From now on, we now plan to respect Semantic Versioning and will release major versions more frequently.

We are on ProductHunt and Hacker News!

Now is the best time to show your love for Docusaurus!

What is Docusaurus exactly?​

Docusaurus is a static site generator that helps you ship beautiful documentation websites in no time.

Focus on your content: just write Markdown files. Docusaurus will generate an optimized website for you that's easy to host anywhere.

Docusaurus is full-featured and very flexible: we ship with well-designed docs and blog layout, as well as out-of-the-box versioning, search, and internationalization functionalities, with a call to accessibility and search engine optimizations. Its flexible theming system permits to adapt the UI to match your branding so that it integrates nicely with your main website or documentation portal. Its usage of React enables a modern client-side navigation, and the ability to build an interactive documentation.

The Docusaurus philosophy is akin to the Pareto principle: you can get 80% of the results for 20% of the effort. This enables you to compete with top-notch documentation sites with minimal effort.

Docusaurus aims to be the best documentation tool, but you can use it for other use-cases as well: a blog, a knowledge base, a developer portfolio, a second brain, or even to scaffold landing pages!

The story behind Docusaurus​

Docusaurus was created at Facebook Open Source in 2017 (now Meta Open Source). We had a lot of internal and open source projects to document. It's complicated enough to write good documentation, let alone to create the HTML, CSS, and JavaScript for a good-looking website. We wanted project leaders to be able to focus on the content, and Markdown is great for that.

At that time, our solution was to copy/paste a Jekyll template over and over again. This naturally became hard to maintain, so we created a tool to solve our own pain once for all.

Docusaurus v1 was born!

It quickly built momentum at Facebook and in the frontend ecosystem, adopted by many popular projects such as Prettier, Babel, React-Native, KaTeX, and of course Docusaurus v1 itself.

Toward Docusaurus 2.0​

Docusaurus v1 has been very successful, but we started to question some architectural choices:

• React was only used as a server-side templating language, and not used on the client
• Theming system was pretty limited, and apart from changing a few colors with CSS, it was difficult to do more advanced customizations
• The docs versioning system was confusing, since it was based on a diff algorithm
• The codebase was monolithic, neither well-tested nor easy to extend

Docusaurus v2 was rebuilt from the ground up with a new modular architecture:

• React is now also used on the client, enabling a modern Single Page Application navigation
• Plugins empower the community to contribute useful features as third-party packages
• Theming is more flexible than ever
• Docs versioning is now based on snapshot copies, much easier to understand
• We kept everything good from v1: docs, blog, pages, versioning, i18n...
• We implemented several new features

Who uses Docusaurus 2.0?​

Despite being in pre-release, it didn't take long for Docusaurus v2 to outgrow Docusaurus v1 in terms of NPM downloads:

Our GitHub star trend is very positive, competing with major frameworks:

Today, Docusaurus v2 has already been a great success even before its launch:

• We received so many lovely testimonials
• Companies like 1Password and Courier are writing down their positive experience
• Our site showcase references hundreds of sites, and this is only the tip of the iceberg.

What's New in 2.0?​

It would be difficult to describe every single new feature coming with Docusaurus v2. Let's focus on the features we believe are the most impactful.

MDX​

MDX allows you to interleave React components in Markdown. This enables you to build top-notch interactive documentation experiences very easily.

A demo is worth a thousand words:

### Give it a try: press that button!

import ColorModeToggle from '@theme/ColorModeToggle';

<ColorModeToggle/>

File system conventions​

Our goal is to make Docusaurus very intuitive to use. We added file system conventions, and adding a doc page is as easy as creating one Markdown file.

プラグイン​

Docusaurus now has a modular architecture with a plugin system — our core features like docs, blog, pages, and search are all powered by individual plugins.

More importantly, it enables our community to enhance Docusaurus with additional features.

Let's highlight some examples:

• redocusaurus: seamless integration with OpenAPI and Redoc

• docusaurus-preset-shiki-twoslash: use Shiki code block syntax highlighting with TwoSlash TypeScript compiler hints

• docusaurus-search-local: one of the various local search alternatives to the built-in Algolia plugin

テーマ​

Theming is one of the most important features of Docusaurus: we believe a professional documentation site should respect your company's branding and create a consistent experience.

Docusaurus theming gives a lot of flexibility on multiple levels:

• Customize CSS variables to adjust colors, fonts, and more
• Provide your own CSS stylesheets
• Implement your own theme from scratch
• Override any React component provided by our default theme: we call this swizzling

This enables users willing to invest a bit more time on customizations to build sites that look different from others.

Other features​

Docusaurus 2 comes with a very long list of useful features:

• Theme: dark mode, better UI and UX, flexible themeConfig options...
• Docs versioning: flexible plugin options to adapt to your workflow
• Docs sidebar: collapsible category, category index pages...
• Blog: multiple authors, authors map, archive page...
• Markdown: tabs, math equations, live code blocks, linking, flexible front matter...
• Search: use the new Algolia DocSearch 3 experience
• Assets: make it easy to incorporate images and other kinds of files
• Internationalization: config options, default theme translations...
• Accessibility: aria labels, color contrasts, skip-to-content, keyboard navigation, progressive enhancement...
• SEO: sensible defaults, easy to customize, canonical url, social card, no-index, sitemap, microdata, hreflang...
• PWA: add offline support to your site, and make it installable
• Fail-fast: strict config validation, detect broken links, and prevent bad production deployments
• TypeScript support for config files, plugins, custom pages and theme authors
• Playgrounds: assess Docusaurus easily from your browser with docusaurus.new
• Canary releases: use the @canary npm tag to use the upcoming release before anyone else
• Tests: Docusaurus is well-tested, we dogfood features and ensure they keep working

Why 2.0 now?​

Many enthusiastic followers of ours have been curious why it took us 4 years to release Docusaurus 2.0, considering the beta is already successful and widely used in production.

The reason is that we aim to respect Semantic Versioning, which means we will be incrementing the major version number whenever we release a breaking change.

It is important for multiple reasons:

• It guarantees simple minor version upgrades, as long as you only use the public API
• It follows front-end ecosystem conventions
• A new major version is an opportunity to thoroughly document breaking changes
• A new major/minor version is an opportunity to communicate new features through a blog post

The problem is that our flexible theming system inherently creates a very implicit API surface on which it is hard to know what is a breaking change in the first place. Highly customized Docusaurus sites sometimes have a hard time upgrading Docusaurus because they achieve customizations using internal APIs. We dedicated time to extensive theme refactors and clearly defining our public API, so that future code changes can be made more safely. We will continue to expand this public theming API so that the most common site customizations do not need to use any internal API.

What's Next?​

The work on Docusaurus 3.0 has started, and this next version will be released only in a few months. We will backport retro-compatible changes in Docusaurus 2.x minor versions to make them available as soon as possible to the community on a stable channel.

A sample of the features on our roadmap for the upcoming major versions of Docusaurus:

• Upgrade to MDX 2.0
• Improve Markdown infrastructure
• Improve theming and swizzle
• TailwindCSS theme
• Theme; support custom item types for navbar, doc sidebar, blog sidebar, footer
• Dynamic navbar: navbar item activation strategies
• Custom Social Cards
• CSS-in-JS support
• Use Node.js ES Modules
• Improve build time performance
• Extend Docusaurus plugins, CMS integration
