Next.js I18n

⚠️

This feature is only available in nextra-theme-docs.

Nextra supports Next.js Internationalized Routing out of the box. These docs explain how to configure and use it.

Add I18n Config

To add multi-language pages to your Nextra application, you need to config i18n in next.config.mjs first:

next.config.mjs

import nextra from 'nextra'
 
const withNextra = nextra({
  theme: 'nextra-theme-docs',
  themeConfig: './theme.config.tsx'
})
 
export default withNextra({
  i18n: {
    locales: ['en', 'zh', 'de'],
    defaultLocale: 'en'
  }
})

Note: You can use any format of UTS Locale Identifiers for defining your locales in the next.config file, e.g. language with region format en-US (English as spoken in the United States).

Configure the Docs Theme

Add the i18n option to your theme.config.jsx to configure the language dropdown:

theme.config.jsx

i18n: [
  { locale: 'en', name: 'English' },
  { locale: 'zh', name: '中文' },
  { locale: 'de', name: 'Deutsch' },
  { locale: 'ar', name: 'العربية', direction: 'rtl' }
]
