import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';
import LanguageDetector from 'i18next-browser-languagedetector';

import en from './locales/en.json';
import fr from './locales/fr.json';

i18n
  .use(LanguageDetector)
  .use(initReactI18next)
  .init({
    resources: { en: { translation: en }, fr: { translation: fr } },
    fallbackLng: 'en',
    interpolation: {
      escapeValue: false,
    },
  });

export default i18n;

Sample en.json:

i18n.changeLanguage('ar');

new Intl.DateTimeFormat('fr-FR').format(new Date());
// Output: 04/05/2025 (French format)

npm install i18next react-i18next i18next-browser-languagedetector
