Javascript Programming Tutorials, Guides & Best Practices

With this setup, your app can:

• Dynamically switch between translated URLs
• Support SEO-friendly, localized routing
• Scale to additional languages easily

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

i18n.changeLanguage('ar');

import i18n from 'i18next';
import { initReactI18next } from 'react-i18next';
import LanguageDetector from 'i18next-browser-languagedetector';

// Import translation files
import en from './locales/en.json';
import fr from './locales/fr.json';

i18n
  .use(LanguageDetector) // Detects user language
  .use(initReactI18next)
  .init({
    resources: {
      en: { translation: en },
      fr: { translation: fr },
    },
    fallbackLng: 'en',
    interpolation: {
      escapeValue: false, // React already escapes
    },
    detection: {
      order: ['localStorage', 'navigator', 'htmlTag'],
      caches: ['localStorage'],
    },
  });

export default i18n;

Create folder structure:

Now let’s set up the main container app.

npx create-react-app app-shell
cd app-shell
npm install -D webpack webpack-cli webpack-dev-server html-webpack-plugin

   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.
