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.

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.

Introducing Slash

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.

Unless you're spinning up a documentation team with engineering resources, you probably want Docusaurus!

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!

Using Docusaurus for my tech blog has been a fantastic choice. It looks tremendous out-of-the-box and the awesome DX means I write way more

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!

Birth of Slash

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.


Notice that the sample sites above use different colors, but still look quite the same.

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:

NPM downloads: v2 outgrows v1

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

GitHub stars: Docusaurus is well-positioned

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

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 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';


Give it a try: press that button!


MDX has its own plugin system. You to customize your Markdown authoring experience, and even create your own Markdown syntax.

Docusaurus + MDX is great: we were able to implement a beautiful two-pane layout and give the author fine-grained control on the placement of code and corresponding prose.

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.

Using the auto-generated sidebars makes it so simple to just create a page and not worry about any other configuration.

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:

The plugin API was a breeze to use, and powerful enough that I could port the code sample renderer from the TypeScript website site in a couple of hours.

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

I love Docusaurus Swizzling feature. It’s opinionated and flexible at the same time. This is super cool since a framework usually needs to sacrifice one for the other.

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

So far it’s working out really nicely. It’s been really easy to style up the way that we wanted it to look. No blockers at all.

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.


From now on, Docusaurus will release new major versions more frequently. In practice, you can expect a new major version every 2 to 4 months.

Major version numbers are not sacred, but we still group breaking changes together and avoid releasing major versions too often.

Check our release process documentation for details.

What's Next?

Slash Up and Running

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:

Thank You

We'd like to express our gratitude to all our contributors, including:
