[i18n] Is translating the complete URL possible?

I try to integrate multi language with @nuxxtjs/i18n v8. Lots of things work, but URLs, while prefixed with the language code, won't get translated. What is /about in English, becomes /de/about in German (instead of /de/ueber-uns ) and /fr/about (instead of /fr/a-propos). Here is a reproduction: https://stackblitz.com/edit/multi-language-test-app?file=README.md Am I wrong in assuming that the complete URL has to be translated? If not, what is wrong with my setup?

Hi @rowild. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the knowledge sources provided, I can answer your question about translating complete URLs with @nuxtjs/i18n v8 in Nuxt. Yes, it is possible to translate the complete URL using @nuxtjs/i18n. The issue in your setup is likely related to the configuration of custom routes. To achieve URL translation, you need to define custom routes in your Nuxt configuration. Here's how you can do it: 1. In your nuxt.config.ts file, add a pages property under the i18n configuration. This property allows you to define custom routes for different languages. 2. Define your routes for each language using the following structure:

i18n: {
  // other i18n config options...
  pages: {
    'about': {
      en: '/about',
      de: '/ueber-uns',
      fr: '/a-propos'
    }
    // Add other pages as needed
  }
}

i18n: {
  // other i18n config options...
  pages: {
    'about': {
      en: '/about',
      de: '/ueber-uns',
      fr: '/a-propos'
    }
    // Add other pages as needed
  }
}

This configuration tells Nuxt to use the specified paths for each language when generating routes. Here's an example of a more complete i18n configuration that includes custom routes:

i18n: {
  defaultLocale: 'en',
  lazy: true,
  langDir: 'lang',
  locales: [
    { code: 'en', iso: 'en-US', file: 'en.json' },
    { code: 'de', iso: 'de-DE', file: 'de.json' },
    { code: 'fr', iso: 'fr-FR', file: 'fr.json' }
  ],
  strategy: 'prefix_except_default',
  customRoutes: 'config',
  pages: {
    'about': {
      en: '/about',
      de: '/ueber-uns',
      fr: '/a-propos'
    }
    // Add other pages as needed
  }
}

i18n: {
  defaultLocale: 'en',
  lazy: true,
  langDir: 'lang',
  locales: [
    { code: 'en', iso: 'en-US', file: 'en.json' },
    { code: 'de', iso: 'de-DE', file: 'de.json' },
    { code: 'fr', iso: 'fr-FR', file: 'fr.json' }
  ],
  strategy: 'prefix_except_default',
  customRoutes: 'config',
  pages: {
    'about': {
      en: '/about',
      de: '/ueber-uns',
      fr: '/a-propos'
    }
    // Add other pages as needed
  }
}

By implementing this configuration, your URLs should be fully translated as you expected: /about for English, /de/ueber-uns for German, and /fr/a-propos for French. For more detailed information on configuring custom routes with @nuxtjs/i18n, you can refer to the Stack Overflow post on Nuxt i18n configuration. Remember to adjust your page components and navigation links to use the localized routes. You can use the localePath composable provided by @nuxtjs/i18n to generate the correct URLs in your application. If you're still experiencing issues after implementing these changes, please provide more details about your specific setup or any error messages you're encountering. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Ok, that indeed works. Partly. Now the following happens: When I switch from English to French, the page does not display the text, but instead the variable that holds the text. That is: menu.home in the navigation, or about.title in the about.vue component. What could be the reason for that?

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the information provided in the knowledge sources and your new question, I can offer some insights into why you're seeing variables like menu.home or about.title instead of the translated text when switching from English to French. This issue is likely related to how your translations are set up and how you're using them in your components. Here are a few potential reasons and solutions: 1. Translation files: Make sure your translation files (e.g., en.json, fr.json) are properly structured and contain the correct key-value pairs for all your translations. For example:

   {
     "menu": {
       "home": "Accueil"
     },
     "about": {
       "title": "À propos"
     }
   }

   {
     "menu": {
       "home": "Accueil"
     },
     "about": {
       "title": "À propos"
     }
   }

2. Using the correct translation function: Ensure you're using the correct translation function in your components. In Nuxt with @nuxtjs/i18n, you typically use the $t function to translate strings. For example:

   <template>
     <div>
       <h1>{{ $t('about.title') }}</h1>
       <nav>
         <a href="/">{{ $t('menu.home') }}</a>
       </nav>
     </div>
   </template>

   <template>
     <div>
       <h1>{{ $t('about.title') }}</h1>
       <nav>
         <a href="/">{{ $t('menu.home') }}</a>
       </nav>
     </div>
   </template>

3. Proper setup of i18n in your components: Make sure you've set up i18n correctly in your components. You might need to use the useI18n composable. Here's an example:

   <script setup>
   const { t } = useI18n()
   </script>

   <template>
     <div>
       <h1>{{ t('about.title') }}</h1>
     </div>
   </template>

   <script setup>
   const { t } = useI18n()
   </script>

   <template>
     <div>
       <h1>{{ t('about.title') }}</h1>
     </div>
   </template>

4. Lazy loading of language files: If you're using lazy loading for your language files, make sure they are being loaded correctly when you switch languages. Check your network tab in the browser developer tools to see if the language file is being fetched when you switch languages. 5. Correct language switching: Ensure you're switching the language correctly. You can use the setLocale function provided by @nuxtjs/i18n:

   const { setLocale } = useI18n()
   
   // To switch to French
   setLocale('fr')

   const { setLocale } = useI18n()
   
   // To switch to French
   setLocale('fr')

If you've checked all these points and are still experiencing issues, it would be helpful to see your specific component code and i18n configuration. The problem might be in how you're implementing the translations in your components or how your i18n is configured. For more detailed information on setting up and using i18n in Nuxt, you can refer to the @nuxtjs/i18n documentation. Remember, without seeing your specific code, these are general suggestions based on common issues. If the problem persists, please provide more details about your implementation, including relevant code snippets from your components and i18n configuration. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Thank you! I found the problem. In the i18n configuration in the nuxt.config.ts file, the lazy option must be set to false, then it works.

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I'm glad you found the solution to your problem! You're correct that setting the lazy option to false in the i18n configuration can resolve the issue you were experiencing. Let me explain why this works and provide some additional context. When the lazy option is set to true, it enables lazy loading of language files. This means that the language files are loaded on-demand when a user switches to a specific language. While this can be beneficial for performance in larger applications with many languages, it can sometimes lead to issues like the one you encountered, where translation keys are displayed instead of the actual translated text. By setting lazy: false, you're telling Nuxt to load all language files upfront. This ensures that all translations are available immediately, preventing the display of raw translation keys. Here's how your i18n configuration in nuxt.config.ts should look now:

i18n: {
  lazy: false,
  langDir: 'lang',
  locales: [
    { code: 'en', iso: 'en-US', file: 'en.json' },
    { code: 'fr', iso: 'fr-FR', file: 'fr.json' },
    // other locales...
  ],
  defaultLocale: 'en',
  // other i18n options...
}

i18n: {
  lazy: false,
  langDir: 'lang',
  locales: [
    { code: 'en', iso: 'en-US', file: 'en.json' },
    { code: 'fr', iso: 'fr-FR', file: 'fr.json' },
    // other locales...
  ],
  defaultLocale: 'en',
  // other i18n options...
}

This change should resolve the issue of seeing variables like menu.home or about.title instead of the translated text when switching languages. However, it's worth noting that for larger applications with many languages, lazy loading (i.e., lazy: true) can be beneficial for performance. If you decide to switch back to lazy loading in the future, you might need to ensure that your language files are being loaded correctly when switching languages. For more information on configuring i18n in Nuxt, you can refer to the @nuxtjs/i18n documentation. I'm glad you were able to resolve your issue. If you have any more questions about Nuxt or i18n, feel free to ask! ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
