process.stdin.on('readable', ()=>{ 
  // reads what is being typed. 
  let variable = process.stdin.read(); 
  // trying to read 
  variable = variable.toString().replace(/\n/, ""); 
  variable = variable.replace(/\r/, ""); });

// Hope this helps

Using the readline module:

var readline = require('readline');
var resp = "";

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

leitor.question("Qual módulo pra ler dados no node.js?\n", function(answer) {
    var resp = answer;
    console.log("\nSua resposta '" + resp + "' foi grava com sucesso numa variável inútil");
    leitor.close();
});
