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:

npm install i18next react-i18next i18next-browser-languagedetector

Set up your translation files, detect user language, and switch languages dynamically using:

As businesses go global, your frontend must cater to users from different regions, languages, and cultures. A well-implemented internationalization (i18n) strategy in your React app ensures:

• Seamless language switching
• Proper formatting of dates, numbers, and currencies
• Better accessibility and user retention
• Improved SEO in multilingual search queries

import React from 'react';

// Lazy load the remote Vue component
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;

By selecting only the necessary state slices, you can optimize component rendering and improve performance.

While Redux remains a powerful tool for state management, there are scenarios where Zustand might be a better fit:
