At itselftools.com, we’ve built over 30 robust applications using Next.js and Firebase, accumulating a wealth of development insights. Today, we’re sharing how to implement multilingual support in your Next.js applications using the next-i18next package. This approach enhances user experience by catering content in various languages, crucial for global reach.
Understanding the Code Snippet
Here’s a closer look at the code snippet involved in setting up next-i18next:
import NextI18Next from ‘next-i18next‘
const nextI18n = new NextI18Next({ defaultLanguage: ‘en‘, otherLanguages: [‘de‘] })
export const getServerSideProps = async ({ req, res }) => {
await nextI18NextMiddleware(req, res, nextI18n)
return { props: { …await serverSideTranslations(req.locale, [‘common‘, ‘footer‘]) } }
}
Step-by-Step Breakdown
Importing Modules: The nextI18NextMiddleware and NextI18Next are imported to facilitate internationalization.
Initializing nextI18Next: NextI18Next is instantiated with English as the default language and German as another option. This sets the foundation for translating content based on user preference/language setting.
getServerSideProps Function: This async function is crucial for server-side rendering in Next.js. The middleware nextI18NextMiddleware is applied to the request and response objects, ensuring the translations are loaded as per the incoming request’s locale.
Returning Translations: The final return from getServerSideProps includes the translated strings needed for the page, specifically from ‘common’ and ‘footer’ namespaces. This makes these translations available as props in your Next.js page components.
Practical Use and Benefits
Utilizing next-i18next not only simplifies managing translations but also automates a lot of the language switching complexities. This setup ensures that your application can serve a wider audience by adapting to their language preferences, which is key for international applications.
