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

• Color psychology changes per region

npm install i18next react-i18next i18next-browser-languagedetector

Create a new file: src/i18n.js

import('./App');

Update src/App.js:

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

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