What you wanna do is in you project's pages folder, you create a folder named myprojectname. Then inside the folder, move your cart.js.
What this does is it adds a /myprojectname/ route to your URLs and to access the cart, you would have to access it like so: /myprojectname/cart
This is how NextJS does routing, based on how you structure your directories.
For more information, you can refer to this link: https://nextjs.org/learn/basics/navigate-between-pages
