Next.js App Router Internationalization (i18n)

You can pick from two options when setting up an app with next-intl and Next.js' App Router, depending on if you'd like to use unique pathnames for every language that your app supports.

With i18n routing→

Uses a top-level [locale] segment for prefixed pathnames like /en/about or domain-based routing like en.example.com/about

Without i18n routing→

Useful if you'd like to provide a locale to next-intl, e.g. based on user settings, or if your app only supports a single language
