Points importants

Tags files

The docs and blog plugins both already supported a tags front matter attribute, enabling you to group related content. But tags declared inline in the front matter are not always ideal.

With #10137, you can now declare a list of pre-defined tags in a tags.yml file:

label: 'Tag 1'
description: 'Tag 1 description'
permalink: /tag-1-permalink

label: 'Tag 2'
description: 'Tag 2 description'
permalink: /tag-2-permalink

These predefined tags can be used in the front matter of your blog or docs files:

tags: [tag1, tag2]

# Title

Keeping tags usage consistent

Use the new onInlineTags: 'throw' plugin option to enforce the usage of predefined tags and prevent contributors from creating new unwanted tags.

Hash Router - Experimental

With 9859, we added a new experimental hash router config option, useful for offline browsing by opening your site locally through the file:// protocol.

export default {
future: {
experimental_router: 'hash',

This mode is not recommended for sites deployed through a web server.

When this mode is turned on, Docusaurus will opt out of static site rendering, and build a client-side single page application where all routes are prefixed with /#/. A single index.html file is generated. This file can be opened locally in your browser by simply clicking it, using the browser file:// protocol. This makes it possible to distribute a Docusaurus site as a .zip file so that readers can browse it offline, without having to install anything complex on their computer apart a web browser.

Docusaurus hash router - local browsing using the file:// protocol

Try browsing our own Docusaurus site built with the hash router:


This feature is experimental. If you try it out, please let us know how it works for you here.

Site Storage - Experimental

Docusaurus uses the browser localStorage API to persist UI state.

But sometimes the storage space is "shared" between multiple sites using the same domain, leading to storage key conflicts. This generally happens in two cases

  • when working on multiple http://localhost:3000 sites
  • when hosting multiple sites under the same domain: and

For this reason, we introduced a new experimental siteStorage configuration option:

export default {
future: {
experimental_storage: {
type: 'localStorage',
namespace: true,

When namespace: true is set, we apply a hash suffix to all the storage keys, making them unique to the current site (based on config.url and config.baseUrl. For example, the theme storage key becomes theme-x6f. It is also possible to provide your own custom suffix namespace: 'suffix'. We also made it possible to use type: 'sessionStorage' instead of the default localStorage.


This feature is experimental. If you try it out, please let us know how it works for you here.
