As I am currently working on my webpage, I thought it would be great if I had an admin page as well so that I can easily update my experience and skills. Now, my page is running as a single-page website. I will make another page and let it be connected by adding a URL path.

Next.JS: Page Router

Next.JS official page - The 'app' Router
I found that the version 13 of Next.JS has the ‘app’ router on their official website. I will simply use the router to implement the routing function. However, I am going to use Page Router here.

Under my project root, I created a pages directory. In the directory, I put my index.tsx file to render out my landing page. To make another route to my admin page, I made another directory, admin, with another index.tsx file. Now I can access the admin page using the /admin URL path.
