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:

In 2025, Google rewards localized content.

• Use language-based subpaths: /en, /fr, /ar
• Generate hreflang tags for each locale
• Translate meta tags: <title>, <meta description>
• Avoid client-only routing for indexable pages
• Pre-render pages via SSR (e.g., with Next.js)

/src
  /locales
    en.json
    fr.json

Example en.json:

We’ll build two apps:

/app-shell         (React)
   webpack.config.js
   src/
       bootstrap.js

/analytics-app     (Vue)
   webpack.config.js
   src/
       main.js
