Translate meta tags using react-helmet or next/head

Enable proper sitemap and routing strategy per locale

Make this dynamic in React:

const formatCurrency = (value, lng) => {
  const currency = lng === 'ar' ? 'EGP' : 'USD';
  return new Intl.NumberFormat(lng, {
    style: 'currency',
    currency
  }).format(value);
};

In large apps, structure your translation files modularly:

/locales
  /en
    home.json
    dashboard.json
  /fr
    home.json
    dashboard.json

• 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.

With these steps, you've set up a basic state management system using Zustand without the need for additional boilerplate or context providers.

While both Zustand and Redux serve the purpose of state management in React applications, they differ significantly in their approach and complexity.
