This module is being used by Drauu which has an integration with VueUse and can be used with Nuxt (Vue). Since Nuxt 3 uses Vite as a bundler by default and it only allows the use of ESM modules, when it tries to bundle perfect-freehand the following error occurs:

import { getStroke } from "perfect-freehand";
^^^^^^^^^
SyntaxError: Named export 'getStroke' not found. The requested module 'perfect-freehand' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'perfect-freehand';
const { getStroke } = pkg;

I was able to "fix" it by adding the following lines into the package.json inside node_modules:

"type": "module",
"exports": {
".": {
"types": "./dist/types/index.d.ts",
"import": "./dist/esm/index.js"
}
}

I'm not sure if this may cause some problems that's why I'm opening an Issue
