Javascript Programming Tutorials, Guides & Best Practices

• 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

• How to structure language-specific routes
• How to integrate URL translation with react-router-dom
• How to switch routes with language changes
• Bonus: how to integrate with react-i18next

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

Use shared in Module Federation to prevent loading duplicate libraries (like react, vue, etc.).

import create from 'zustand';
import { devtools } from 'zustand/middleware';

const useStore = create(devtools((set) => ({
  count: 0,
  increase: () => set((state) => ({ count: state.count + 1 })),
})));

You can persist state to localStorage or sessionStorage:
