Javascript Programming Tutorials, Guides & Best Practices

When building a multilingual React application, translating the visible content is just part of the job. To make your app SEO-friendly and user-centric, you also need to:

• Translate URLs/slugs (e.g., /about-us → /fr/a-propos)
• Maintain SEO with hreflang for each language
• Improve UX by aligning URLs with user language
• Ensure route accessibility via browser language or manual switching

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

Languages like Arabic and Hebrew need RTL layouts. Use CSS:

detection: {
  order: ['localStorage', 'navigator', 'htmlTag'],
  caches: ['localStorage'],
}

This saves the user's preferred language so it's remembered on the next visit.

• Increased complexity
• More testing needed (integration)
• SEO handling is trickier in client-rendered apps

To improve Google indexing:

• 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.

These features make Zustand an attractive choice for developers looking to manage state in a more concise and efficient manner.
