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.

export default defineNuxtConfig({
// ...
i18n: {
vueI18n: {
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']
// ...
