Everything that can be ran from command line can be ran from JS, so yes:

require('child_process').exec('npm pack', console.log)

You don't have to run npm pack command to create tarball.

Just use tar package:

const tar = require('tar');
const fstream = require('fstream');

function pack({ path, target }) {
  fstream
    .Reader({ path, type: 'Directory' })
    .pipe(tar.Pack({ noProprietary: true }))
    .pipe(fs.createWriteStream(target));
}

const name = 'your-folder-package';

pack({
  path: path.join(__dirname, 'packages', name),
  target: path.join(__dirname, 'dist/packages', `${name}.tar`),
});
