Basics on Translation in Docusaurus​

This template has a French translation for docs, but only one doc, i18n/fr/docusaurus-plugin-content-docs/start.md, is translated.

Because English is set to the default language, for other languages, if there is no translation file, the English one will be used.

Pre-configs for Chinese (zh) 🇨🇳🇭🇰🇲🇴🇹🇼🇸🇬​

This boilerplate is using a Local Search plugin with index for Chinese (zh) support pre-configurated.

The local search plugin uses nodejieba to index Chinese language. It requires specified nodejs versions, and this is pre-configured in .nvmrc file.

If you won't be doing Chinese translation or using other search index services, you can remove .nvmrc file and remove nodejieba from your project:

yarn remove nodejieba

Add/remove a language​

This example will guide you to add Spanish (es) 🇪🇸 to your website.

Configure i18n​

Update defaultLocale and locales in docusaurus config file

  • defaultLocale: default language
  • locales: languages in this site

Add es to locales:

docusaurus.config.js
const config = {
  i18n: {
    defaultLocale: 'en',
    locales: ['en', 'fr', 'es'],
  },

Update search setting in docusaurus config file, add es to the language:

docusaurus.config.js
const config = {
  plugins: [
    [require.resolve('@cmfcmf/docusaurus-search-local'), {
      // language of your documentation, see next section
      language: ["en", "fr", "es"],
    }]
  ],

Translate a doc​

Docs for es are placed under i18n/es/docusaurus-plugin-content-docs/current/

mkdir -p i18n/es/docusaurus-plugin-content-docs/current/

cp docs/start.md i18n/es/docusaurus-plugin-content-docs/current/start.md

Translate i18n/es/docusaurus-plugin-content-docs/current/start.md in Spanish.

Translate a blog post​

Blog posts for es are placed under i18n/es/docusaurus-plugin-content-blog

Copy your blog Markdown files to i18n/es/docusaurus-plugin-content-blog, and translate them:

Translate pages​

Pages for es are placed under i18n/es/docusaurus-plugin-content-pages

mkdir -p i18n/es/docusaurus-plugin-content-pages
cp -r src/pages/**.md i18n/es/docusaurus-plugin-content-pages
cp -r src/pages/**.mdx i18n/es/docusaurus-plugin-content-pages

Translate other strings​

Translate Navbar, Footer, Global strings in Docs and Blog, i18n strings in code is a ton of works. This template is using docusaurus-theme-classic, and it should be no setup for the UI translation out of the box.

Docusaurus provide a quick way to generate json files for all strings supports i18n by running:

# replace `es` for your desired language
yarn run write-translations -- --locale es

This will generate the following files:

  project-root
  ├── i18n
  │   └── es
  │       ├── docusaurus-plugin-content-blog
+ │       │   └── options.json
  │       │
  │       ├── docusaurus-plugin-content-docs
+ │       │   └── current.json
  │       │
  │       └── docusaurus-theme-classic
+ │       │   ├── footer.json
+ │       │   └── navbar.json
  │       │
+ │       └── code.json
  .

You can continue translating other strings with the generated json files.

Run local dev server in another language​

yarn start -- --locale es
