Does NodeJS has any functionality for accepting input via standard input from a user. In Browser based JS we used to use 'prompt' functionality for same but the this would not work on NodeJS standalone app.
node one.js
Enter any number:
<program accepts the number and does the processing>
As vinayr said, you should use readline. An example of what you desire:
var readline = require('readline');
var rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
rl.question("Input number:", function(numAnswer) {
// TODO: Log the answer in a database
var num = parseInt(numAnswer);
processingFunctionYouUse(num);
rl.close();
});

I would like to suggest you to use stdio. It is a module that aims to simplify your life with standard input/output. One of its main features is the standard input reading, line by line, and it can be done as follows:
var stdio = require('stdio');
stdio.readByLines(function (line) {
// This function is called for every line while they are being read
}, function (err) {
// This function is called when the whole input has been processed
});
PD: I'm the stdio creator. :-)
