Routing Strategies
pages directory to control routing.Routing
Nuxt i18n module overrides Nuxt default routes to add locale prefixes to every URL (except in no_prefix strategy).
Say your app supports two languages: French and English as the default language, and you have the following pages in your project:
└── pages
    ├── about
    │   └── index.vue
    └── index.vue
This would result in the following routes being generated
[
  {
    path: "/",
    name: "index___en",
    ...
  },
  {
    path: "/fr/",
    name: "index___fr",
    ...
  },
  {
    path: "/about",
    name: "about___en",
    ...
  },
  {
    path: "/fr/about",
    name: "about___fr",
    ...
  }
]
Note that routes for the English version do not have any prefix because it is the default language, see the routing strategies section for more details.
Strategies
There are 4 supported strategies that affect how app's routes are generated:
no_prefix
With this strategy, your routes won't have a locale prefix added. The locale will be detected & changed without changing the URL. This implies that you have to rely on browser & cookie detection, and implement locale switches by calling the i18n API.
differentDomains.prefix_except_default
Using this strategy, all of your routes will have a locale prefix added except for the default language.
prefix
With this strategy, all routes will have a locale prefix.
prefix_and_default
This strategy combines both previous strategies behaviours, meaning that you will get URLs with prefixes for every language, but URLs for the default language will also have a non-prefixed version (though the prefixed version will be preferred when detectBrowserLanguage is enabled).
Configuration
To configure the strategy, use the strategy option.
Make sure that you have a defaultLocale defined, especially if using prefix_except_default, prefix_and_default or no_prefix strategy. For other strategies it's also recommended to set this as it will be used as a fallback when attempting to redirect from a 404 page.

  i18n: {
    strategy: 'prefix_except_default',
    defaultLocale: 'en'
