I'm trying to load a config inside a node module but I'm not sure which is a good practice to do it, I have this scenario:

A config my.config.js:

module.exports = {
  content: [
    './src/**/*.{tsx,ts}',
  ],
}

Then I have a module cli.mjs is supposed to load it:

import arg from 'arg'
import { readFile } from 'fs/promises'
import path from 'path'

let configPath = './my.config.js'

const args = arg({
  '--config': String,
  '-c': '--config',
})

if (args['--config']) {
  configPath = args['--config']
}

console.log(readFile(path.resolve(configPath), { encoding: 'utf8' }))

This will just return a simple string with my config inside, not a javascript object:

`
module.exports = {
  content: [
    './src/**/*.{tsx,ts}',
  ],
}
`

How should I load my config in the right way?

I've saw basically everyone use configs like that in TypeScript or CJS projects, but it's hard to me see how and where they parse these configs, probably I'm missing some basic information about this?
