I’m building a web application using Next.js and need to implement internationalization (i18n) to support multiple languages. I’ve researched various approaches but haven’t found a clear, comprehensive guide tailored specifically to Next.js.

What is the recommended way to set up internationalization in a Next.js project? I’m particularly interested in solutions that allow for easy management of translations, dynamic language switching, and SEO optimization.

If there are any popular libraries or best practices for i18n in Next.js, I’d appreciate recommendations and guidance on how to integrate them into my project effectively.

Thank you for your assistance!

Additional Info:

Next.js version: 12.3.0
React version: 18.0.0
Desired outcome: Implement internationalization in a Next.js application to support multiple languages with ease of management and SEO optimization

Code Snippet:

// Example of how I currently render text in my Next.js application
import { useRouter } from 'next/router';
import { useEffect, useState } from 'react';

const HomePage = () => {
  const router = useRouter();
  const [language, setLanguage] = useState('en');

  useEffect(() => {
    // Fetch user's preferred language or use default
    const userLanguage = navigator.language || navigator.userLanguage;
    setLanguage(userLanguage);
  }, []);

  // Assume translations are stored in language-specific JSON files
  const translations = {
    en: {
      greeting: 'Hello, world!',
      about: 'About Us',
      contact: 'Contact Us',
    },
    fr: {
      greeting: 'Bonjour le monde!',
      about: 'À Propos',
      contact: 'Contactez-nous',
    },
    // Add translations for other languages as needed
  };

  return (
    <div>
      <h1>{translations[language].greeting}</h1>
      <nav>
        <ul>
          <li>{translations[language].about}</li>
          <li>{translations[language].contact}</li>
        </ul>
      </nav>
    </div>
  );
};

export default HomePage;

In this code snippet, I’ve provided an example of how I currently render text in my Next.js application. I’m looking for guidance on how to improve this approach to implement internationalization effectively.
