Different domains

You might want to use a different domain name for each language your app supports. To achieve this:

• Set differentDomains option to true
• Configure the locales option as an array of objects, where each object has a domain key whose value is the domain name you'd like to use for that locale. Optionally include a port (if non-standard) and/or a protocol. If the protocol is not provided then an attempt will be made to auto-detect it but that might not work correctly in some cases like when the pages are statically generated.
• Optionally set detectBrowserLanguage to false. When enabled (which it is by default), user can get redirected to a different domain on first visit. Set to false if you want to ensure that visiting given domain always shows page in the corresponding locale.

i18n: {
  locales: [
    {
      code: 'en',
      domain: 'mydomain.com'
    },
    {
      code: 'es',
      domain: 'es.mydomain.com'
    },
    {
      code: 'fr',
      domain: 'fr.mydomain.com'
    },
    {
      code: 'ru',
      domain: 'http://ru.mydomain.com'
    },
    {
      code: 'ua',
      domain: 'https://ua.mydomain.com'
    }
  ],
  differentDomains: true
  // Or enable the option in production only
  // differentDomains: (process.env.NODE_ENV === 'production')
}

When using different domain names, your lang switcher should use regular <a> tags:

<a v-for="locale in $i18n.locales" :href="switchLocalePath(locale.code)" :key="locale.code">
  {{ locale.code }}
</a>

Runtime environment variables

Sometimes there's a need to change domains in different environments, e.g. staging and production. As nuxt.config.js is used at build time it would be necessary to create different builds for different environments.

The alternative way is to keep the domains in Vuex store under localeDomains property. It can be accessed by the plugin during the initialisation, saving the trouble building multiple images.

module.exports = {
  uk: process.env.DOMAIN_UK,
  fr: process.env.DOMAIN_FR
}

const localeDomains = require('./config/locale-domains')
[
  '@nuxtjs/i18n',
  {
    differentDomains: process.env.NODE_ENV === 'production',
    locales: [
      {
        code: 'uk',
        domain: localeDomains.uk, // optional
      },
      {
        code: 'fr',
        domain: localeDomains.fr, // optional
      },
    ],
  },
]

const localeDomains = require('~~/config/locale-domains')

export const state = () => ({
  localeDomains
})
