Javascript Programming Tutorials, Guides & Best Practices

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

• Add 404 fallbacks for non-matching paths
• Integrate i18next-http-backend to load translations from a CMS
• Use language subdomains (e.g., fr.site.com) for region-specific experiences

body[dir='rtl'] {
  direction: rtl;
  text-align: right;
}

Switch dir dynamically:

import ICU from 'i18next-icu';

i18n
  .use(ICU) // Enables datetime and currency formatting
  .use(LanguageDetector)
  .use(initReactI18next)
  .init({
    ...
    interpolation: {
      format: (value, format, lng) => {
        if (format === 'datetime') {
          return new Intl.DateTimeFormat(lng).format(value);
        }
        if (format === 'currency') {
          return new Intl.NumberFormat(lng, {
            style: 'currency',
            currency: lng === 'fr' ? 'EUR' : 'USD',
          }).format(value);
        }
        return value;
      },
    }
  });
