Create i18n.js:

• Text translation (i18n)
• Locale-aware formatting (dates, numbers, currencies)
• Cultural UX adaptations (e.g., RTL layouts, color symbolism)
• Language switching + SEO compatibility
• Region-based content rendering (e.g., laws, units, timezones)

In 2025, more users are accessing the web from non-English regions than ever before. Some reasons to globalize your React app:

{
  "welcome": "Bienvenue sur notre plateforme !",
  "language": "Langue",
  "date_example": "La date d'aujourd'hui est {{date, datetime}}",
  "price_example": "Prix : {{price, currency}}"
}

Edit src/index.js:

• 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

In 2025, micro-frontends are not just a buzzword — they are a proven way to scale modern frontend architectures. With Webpack Module Federation, teams can deliver independently developed features without sacrificing user experience or performance.

Zustand allows you to select specific parts of the state to prevent unnecessary re-renders:

const count = useStore((state) => state.count);
