You can follow this guide inside the docs, to create a powerful internationalation: https://nextjs.org/docs/app/building-your-application/routing/internationalization#terminology
@Tonkinese

You will also able to choose if you want to do it via subdomains e.g.:
example.de/
example.fr/
example.com/
…

Or doing it inside the path:
example.com/de
example.com/fr
example.com/en

Internationalisation already in the project i just want to prefix country code after domain url on base of user country from his ip countrycode will be prefix in all routes

Yea, you can do it via the middleware

@B33fb0n3 can you suggest some code i tried it but didnt work

Yea, I do this one:


let locales = ['en-US', 'nl-NL', 'nl']

// Get the preferred locale, similar to the above or using a library
function getLocale(request) { ... }

export function middleware(request) {
// Check if there is any supported locale in the pathname
const { pathname } = request.nextUrl
const pathnameHasLocale = locales.some(
(locale) => pathname.startsWith(/${locale}/) || pathname === /${locale}
)

if (pathnameHasLocale) return

// Redirect if there is no locale
const locale = getLocale(request)
request.nextUrl.pathname = /${locale}${pathname}
// e.g. incoming request is /products
// The new URL is now /en-US/products
return Response.redirect(request.nextUrl)
}

export const config = {
matcher: [
// Skip all internal paths (_next)
'/((?!_next).*)',
// Optional: only run on root (/) URL
// '/'
],
}


Inside the getLocale you can choose if you want to get the language based on the user browser preferences or depending on the location or whatever
