Javascript Programming Tutorials, Guides & Best Practices

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;

• Wider reach
• Better SEO
• User trust and satisfaction
• Competitive advantage

• Integrate with Next.js for SSR & SEO boost
• Enable dynamic locale loading for performance
• Add translation CMS support (Locize, Phrase)

npm install i18next-icu

Update i18n.js:

Micro-frontends allow different teams to work independently on isolated UI components, which are then stitched together at runtime. This enables:

• Faster deployment cycles
• Independent scaling of frontend parts
• Team autonomy across tech stacks (e.g., React, Vue, Angular)

   import React from 'react';
   import useStore from './store';

   function Counter() {
     const { count, increase, decrease } = useStore();
     return (
       <div>
         <h1>{count}</h1>
         <button onClick={increase}>Increase</button>
         <button onClick={decrease}>Decrease</button>
       </div>
     );
   }

   export default Counter;

With these steps, you've set up a basic state management system using Zustand without the need for additional boilerplate or context providers.
