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;

Create pages/Home.js:

i18n.changeLanguage('ar');

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

Create folder structure:

/src
  /locales
    en.json
    fr.json

Module Federation is a feature in Webpack 5 that enables one JavaScript application (host) to dynamically load code from another (remote) at runtime.

• Load remote components/apps on demand
• Share dependencies to avoid duplication
• Enable code splitting across teams
• Works with different JS frameworks

These features make Zustand an attractive choice for developers looking to manage state in a more concise and efficient manner.

Getting started with Zustand is straightforward. Here's how you can integrate it into your React application:
