next-i18next App Router example (no locale in path)

This example shows how to use next-i18next v16 with the Next.js App Router without a locale prefix in the URL (cookie-based language detection).

URLs stay clean (/about instead of /en/about), and language switching is handled via useChangeLanguage().

It demonstrates:

Server Components using getT() from next-i18next/server
Client Components using useT() from next-i18next/client
Cookie-based language detection via createProxy() in proxy.js (no URL redirects)
useChangeLanguage() hook for switching languages
I18nProvider for client-side hydration

Getting started

npm install
npm run dev

This example was originally based on this blog post and discussion.
