There are three solution for it on NodeJS platform

1. For asynchronous use case need, use Node API: readline

Like: ( https://nodejs.org/api/readline.html )

const readline = require('readline');

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

rl.question('What do you think of Node.js? ', (answer) => {
  // TODO: Log the answer in a database
  console.log(`Thank you for your valuable feedback: ${answer}`);

  rl.close();
});

2. For synchronous use case need, use NPM Package: readline-sync Like: ( https://www.npmjs.com/package/readline-sync )

   var readlineSync = require('readline-sync');

   // Wait for user's response. var userName = readlineSync.question('May I have your name? '); console.log('Hi ' + userName + '!');

3. For all general use case need, use **NPM Package: global package: process: ** Like: ( https://nodejs.org/api/process.html )

For taking input as argv:

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