Javascript Programming Tutorials, Guides & Best Practices

Create i18n.js:

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;

document.documentElement.setAttribute('dir', i18n.language === 'ar' ? 'rtl' : 'ltr');

• Use locale-sensitive images and icons

Install i18next-format plugin (optional):

npm install i18next-icu

To improve Google indexing:

• Use SSR (Server-Side Rendering) for public pages
• Add <meta> tags and Open Graph data dynamically
• Ensure Lighthouse scores are optimized (especially for CLS, LCP)
• Avoid client-only routing for key landing pages

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.
