const targetPath = 'cat.jpg'

function Exec(cmd, cwd) {
  cwd = cwd || path.resolve('./')
  return new Promise((resolve, reject) => {
    console.log(`> \x1b[2m${cmd}\x1b[0m`)
    exec(cmd, { cwd }, (error, stdout, stderr) => {
      if (error) { console.error(`error: ${error}`); reject(error); return }
      if (stdout) console.log(stdout)
      if (stderr) console.log(stderr)
      resolve(stdout)
    })
  })
}

await Exec(`exiftool -xmp:Rating=${targetRating} -xmp:Label='${targetLabel}' -overwrite_original '${targetPath}'`)

const { xmpRating, xmpLabel } = (await Exec(`exiftool -xmp:Rating -xmp:Label '${targetPath}'`))
  .split('\n')
  .filter(line => !!line.trim())
  .map(line => line.split(':').map(str => str.trim()))
  .reduce((acc, [key, value]) => {
    acc[`xmp${key}`] = value
    return acc
  }, {})

console.log({ targetRating, xmpRating })
