Hi there,
Why do you need Next.js? Do you need a certain feature from this library?
You can already write Chrome extensions with vanilla JavaScript.
I recently wrote my own modularized tutorial for new and beginner developers. Where you learn how to set up your development environment (custom template) and create your first Chrome extension Manifest V3. That with the modern use of NPM, and ESLint. So you can write concisely JSON, HTML, JavaScript, and CSS code:
Thanks,
