Translate meta tags using react-helmet or next/head

Enable proper sitemap and routing strategy per locale

• 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:

resources: {
  en: {
    home: require('./locales/en/home.json'),
    dashboard: require('./locales/en/dashboard.json'),
  },
  fr: {
    home: require('./locales/fr/home.json'),
    dashboard: require('./locales/fr/dashboard.json'),
  },
},
ns: ['home', 'dashboard'],
defaultNS: 'home',

In component:

Let’s say you’re building a dashboard app in React, but your analytics module is handled by another team using Vue. You don’t want to tightly couple the two.

With Webpack Module Federation, you can load the Vue-based analytics micro-frontend into the React host — all without bundling it directly.

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

By selecting only the necessary state slices, you can optimize component rendering and improve performance.
