The process.argv property returns an array containing the command-line arguments passed when the Node.js process was launched. The first element will be process.execPath. See process.argv0 if access to the original value of argv[0] is needed. The second element will be the path to the JavaScript file being executed. The remaining elements will be any additional command-line arguments.

import { argv } from 'node:process';

// print process.argv
argv.forEach((val, index) => {
  console.log(`${index}: ${val}`);
});
