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:

• Adapt units and metrics

°C vs °F, km vs miles, 12h vs 24h clock.

Edit src/index.js:

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import './i18n'; //  import i18n config

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<App />);

As web applications grow larger and teams become more distributed, the traditional monolithic frontend architecture becomes harder to scale. Enter micro-frontends — the 2025-ready solution that brings backend microservices thinking to the frontend world.

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

Key Features:

• Simplicity: Create stores using a straightforward API without the need for reducers or action types.
• Performance: Optimized for performance with selective rendering and minimal re-renders.
• Flexibility: Supports custom hooks, middleware, and integration with other libraries.
• No Providers: Unlike Redux, Zustand doesn't require wrapping your app with context providers.
