Nuxt I18n

Nuxt I18n owns locale messages, localized routes, language detection, and locale metadata. Nuxt owns the surrounding page, rendering, and server lifecycle.

Workflow

Inspect the installed
```
@nuxtjs/i18n
```
version,
```
nuxt.config.*
```
,
```
i18n/i18n.config.*
```
, locale files, and affected pages. The setup is understood when locale codes, files,
```
defaultLocale
```
, and the routing strategy agree.
Open the smallest matching guide below. Keep module options in
```
nuxt.config
```
, Vue I18n options in
```
i18n.config
```
, and translated messages in locale files.
Implement with localized links and module composables so routing, message loading, and SEO share one locale state.
Run
```
nuxi prepare
```
and the project's typecheck, then visit the affected route in the default and one secondary locale. The change is complete when both locales render the expected message, URL, language metadata, and fallback behavior.

Task	Open
Installation, locale objects, file layout, browser detection, or Vue I18n config	Configuration
Translation keys, interpolation, plurals, dates, numbers, or runtime message loading	Messages

Nuxt pages, middleware, data fetching, SSR state, or server routes	`nuxt` skill

Baseline

bash

npx nuxi@latest module add @nuxtjs/i18n

ts

export default defineNuxtConfig({
  modules: ['@nuxtjs/i18n'],
  i18n: {
    defaultLocale: 'en',
    locales: [
      { code: 'en', language: 'en-US', name: 'English', file: 'en.json' },
      { code: 'fr', language: 'fr-FR', name: 'Français', file: 'fr.json' },
    ],
  },
})

json

{
  "welcome": "Welcome"
}

Locale files resolve from

i18n/locales/

by default. Use the same locale code in configuration, route helpers, locale files, and fallback rules.
