Compare Versions

import { version } from 'node-version';

if (version.isAtLeast('20.0.0')) {
  console.log('Running on Node.js 20 or newer');
}

if (version.is('22.0.0')) {
  console.log('Running on exactly Node.js 22.0.0');
}

if (version.isAbove('20.0.0')) {
  console.log('Running on Node.js strictly above 20.0.0');
}

if (version.isBelow('22.0.0')) {
  console.log('Running on Node.js strictly below 22.0.0');
}
