What needs to be added to path @/lib/utils when trying to use shadcn/ui components?

Question

I am trying to use the shadcn dropdown component in my react application. I am not using Tailwind. I followed their docs and chose the path to add the code manually, but now I get an error:

Module not found: Can't resolve '@/lib/utils'
  3 | import { CheckIcon, ChevronRightIcon, DotFilledIcon } from "@radix-ui/react-icons";
  4 |
> 5 | import { cn } from "@/lib/utils";
  6 |
  7 | const DropdownMenu = DropdownMenuPrimitive.Root;

Please guide me on what needs to be added to folder @/lib/utils.

Answer 1

cn() can be found in the shadcn git repo:

import * as React from "react"
import { clsx, type ClassValue } from "clsx"
import { twMerge } from "tailwind-merge"

export function cn(...inputs: ClassValue[]) {
    return twMerge(clsx(inputs))
}
