I'm working on adding multilingual support to a Next.js 15 app using a server-side approach—completely avoiding global state for simplicity and maintainability. The goal is to dynamically switch between English and Arabic using JSON translation files, while automatically adapting layout direction between LTR and RTL. A simple toggle button in the navbar handles the switch, ensuring the entire app—or even just the current page—updates seamlessly.
Any guidance or insights would be appreciated.
