Enable proper sitemap and routing strategy per locale

Translating URLs in React improves both UX and SEO, especially in 2025 where Google increasingly favors language-aware URLs over query parameters like ?lang=fr.

Languages like Arabic and Hebrew need RTL layouts. Use CSS:

body[dir='rtl'] {
  direction: rtl;
  text-align: right;
}

import React from 'react';
import { useTranslation } from 'react-i18next';

const Home = () => {
  const { t, i18n } = useTranslation();

  const changeLanguage = (lng) => {
    i18n.changeLanguage(lng);
  };

  const today = new Date();
  const price = 199.99;

  return (
    <div className="p-4">
      <h1>{t('welcome')}</h1>

      <div className="mt-4">
        <strong>{t('language')}:</strong>
        <button onClick={() => changeLanguage('en')} className="ml-2">EN</button>
        <button onClick={() => changeLanguage('fr')} className="ml-2">FR</button>
      </div>

      <p>{t('date_example', { date: today })}</p>
      <p>{t('price_example', { price })}</p>
    </div>
  );
};

export default Home;

import React from 'react';

const Analytics = React.lazy(() => import('analytics_app/Analytics'));

function App() {
  return (
    <div className="App">
      <h1>Host Dashboard</h1>
      <React.Suspense fallback={<div>Loading Analytics...</div>}>
        <Analytics />
      </React.Suspense>
    </div>
  );
}

export default App;

Start the remote app (Vue):
