I'm building a single page application and importing .js files dynamicly when needed on the client using await import(`./scripts/script.js`).

Proplem

is that the scripts folder has files for guests, members and admins, so now any one can import those files from the browser console and see or run the code in it, NOTE i dont have anything to hide in those files, but for example, i still want to prevent a guest from just imorting member or admin files at will.

NOTE: we're using Node.js for the backend)

Question

Can the server detect/intersept the incoming request for the file from the browser when import(`./scripts/script.js`) is called ? If not, is there any other way ?

Clarification

I just need a way to request js/css files from the server and have the server decide whether to send me the requested files or not.
