Next.js Internationalization Made Simple with next-i18n-router

Internationalizing Next.js applications could make them truly globalized applications for an audience. Somehow, next-i18n-router simplifies and improves this: automatic direction by users to the correct localized pages. However, Next itself provides internal support for internationalization.

next-i18n-router is a library that helps manage locale-based routing in Next.js applications. It provides automatic redirects based on the user's preferred language and ensures a smooth experience when handling multi-language URLs.

• Automatic Language Detection – Redirects users based on browser language settings.

• SEO-Friendly URLs – Enables clean, localized URLs (e.g., /en/about, /fr/about).

• Seamless Navigation – Works well with Next.js' next/router for smooth locale switching.

To install next-i18n-router, run:

npm install next-i18n-router

Integrate next-i18n-router in your _app.tsx to handle language-based routing:

import { appWithI18nRouter } from 'next-i18n-router';
import i18nConfig from '../i18nConfig';
function MyApp({ Component, pageProps }) {
return <Component {...pageProps} />;
}
export default appWithI18nRouter(MyApp, i18nConfig);
Define your i18nConfig.js:
const i18nConfig = {
locales: ['en', 'fr', 'de'],
defaultLocale: 'en',
localeDetection: true
};
export default i18nConfig;

• Improves User Experience – Users land on their preferred language automatically.

• Boosts SEO – Search engines can index language-specific pages correctly.

• Simplifies Navigation – Developers can manage locale switching efficiently.

You've heard right. Next-i18n-router is a tool for Next.js for simplifying the routing and localization in multilingual applications running in a Next.js setting. You could really use this plugin inside your application in order to serve a better, seamless experience across the globe for your user.
