import I18n from "i18n-js";
// allows nl-NL to fallback to nl if no nl-NL translation is defined
I18n.fallbacks = true;
I18n.autoDetectLocale = ({ defaultLocale }) => {
const userLocale = navigator.userLanguage || navigator.language;
I18n.defaultLocale = defaultLocale;
if (userLocale in I18n.translations) {
// exact locale is supported, use that
return (I18n.locale = userLocale);
}
const language = userLocale.match(/^[a-z]{2}/i)[0];
for (const locale in I18n.translations) {
if (locale.match(/^[a-z]{2}/i)[0] === language) {
// we've got a match on language, use that
return (I18n.locale = locale);
}
}
