This ensures your SSH client pings the server regularly.

That’s it. With these changes, your SSH session will stay alive and won’t drop after just a minute.

Update App.js:

import React from 'react';
import { useTranslation } from 'react-i18next';
import { BrowserRouter, Routes, Route, useNavigate } from 'react-router-dom';
import { routes } from './routes';
import './i18n';

const LanguageSwitcher = () => {
  const { i18n } = useTranslation();
  const navigate = useNavigate();

  const switchLang = (lang) => {
    const currentPath = window.location.pathname;
    const currentPage = currentPath.split('/')[1];

    i18n.changeLanguage(lang).then(() => {
      // Re-map path using new language
      const t = i18n.getFixedT(lang);
      const mappedRoutes = {
        en: { accueil: 'home', 'a-propos': 'about-us' },
        fr: { home: 'accueil', 'about-us': 'a-propos' },
      };

      const newPath = `/${mappedRoutes[lang][currentPage] || ''}`;
      navigate(newPath);
    });
  };

  return (
    <div className="lang-switch">
      <button onClick={() => switchLang('en')}>EN</button>
      <button onClick={() => switchLang('fr')}>FR</button>
    </div>
  );
};

const App = () => {
  const { t } = useTranslation();

  return (
    <BrowserRouter>
      <LanguageSwitcher />
      <Routes>
        {routes(t).map((route, idx) => (
          <Route key={idx} path={route.path} element={route.element} />
        ))}
      </Routes>
    </BrowserRouter>
  );
};

export default App;

• GDPR requires local-language privacy policies
• China's Cybersecurity Law needs local hosting + Mandarin support
• Saudi localization laws mandate Arabic for all government services

Your React app must support legal localization where applicable.

{
  "welcome": "Bienvenue sur notre plateforme !",
  "language": "Langue",
  "date_example": "La date d'aujourd'hui est {{date, datetime}}",
  "price_example": "Prix : {{price, currency}}"
}

Edit src/index.js:

Then start the host app (React):

cd app-shell
npx webpack serve
