How to make the name of the saved file and the name that will be sent to the database the same, but at the same time unique?

Question

MongoDB

Guys, such a problem, I have to save the file and it must have a unique name, just like the file name that is saved in the database.
But the process of generating the name of the FILE (multer filename) is now in the file user.routes.js, and the process of generating the name of the file that will be sent to the database file userController.js how can I make the file name that will be saved locally, and the name file that will be written to the database were uniquely the same?
I use nanoid
