ExifReader

This shows how to get all the tags, and then pull the description out (which is where Lightroom Classic stores it)

#!/usr/bin/env node

const ExifReader = require('exifreader')
const input_file = '/Users/alan/Photos/web-exports/aws-2022-0315-1507-0001.jpg'

async function runIt() {
  const tags = await ExifReader.load(input_file)
  console.dir(tags)
}

runIt()
