Refactor to use Nextjs app directory #7
Description
Since next.js 13.4 app router is now stable. We should refactor this code to use app router instead as imo server rendered component it is the future of react and nextjs.
But I think current pages also need to be maintain at least for now. So creating a git tag or branch for both type of app is a must. this is also a new thing to me. Just found something related to this: Git tags vs branches: Differences and when to use them
