I don't want full luxon package as I'm only importing some functions from it.

// index.js
const luxon = require('luxon');

const end = luxon.DateTime.fromISO('2003-05-29');
const start = luxon.DateTime.fromISO('2022-05-03');
console.log(end.diff(start, ['years', 'months', 'days']).toObject());

How can I bundle only required functions (eg. DateTime, fromISO, diff) in index.min.js

Edit 1:

I tried esbuild, but it just bundle whole package

npx esbuild index.js --bundle --outfile=index.min.js
