How to take user input from the command line in Node.js

In order to take user input from the command line, you can use the readline module. It provides an interface for reading data from a Readable stream (such as process.stdin) one line at a time.

import readline from 'node:readline';
import { stdin as input, stdout as output } from 'node:process';
 
const rl = readline.createInterface({ input, output });
 
rl.question('What do you think of Node.js? ', (answer) => {
  console.log(`Thank you for your valuable feedback: ${answer}`);
  rl.close();
});
 
rl.on('close', () => {
  console.log('\nBYE BYE !!!');
  process.exit(0);
});
