Locale fallback

How a fallback gets selected when a translation is missing.

Nuxt i18n module takes advantage of Vue I18n ability to handle localization fallback. It is possible to define a single fallback locale, an array of locales, or a decision map for more specific needs.

i18n.config.ts
export default {
  fallbackLocale: 'en',
  // or
  fallbackLocale: ['en', 'fr'],
  // or
  fallbackLocale: {
    'de-CH':   ['fr', 'it'],
    'zh-Hant': ['zh-Hans'],
    'es-CL':   ['es-AR'],
    'es':      ['en-GB'],
    'pt':      ['es-AR'],
    'default': ['en', 'da']
  }
  // ...
}
