Why I can't use this function inside my front-end app to define what mime type is file?

Because fileTypeFromFile is used to access files on you local file system, which is only possible via Node.js file sytem API.

If you want to read a File (a File you uploaded in a browser environment), you can use fileTypeFromBlob(blob).

This could be better documented in the README, please keep this issue open until that is clearly captured.
