Snippet for node.js to prevent any user input while script is working, but process ctrl+c to exit

prevent-input.js

// doesn't work w/o this interface creation
require('readline').createInterface({
  input: process.stdin,
  output: process.stdout
});

// stop process input
process.stdin.pause();

// read from stdin 10 times per second to check if ctrl+c pressed
setInterval(function(){
  var chunk = process.stdin.read();
  if (chunk)
    for (var i = 0; i < chunk.length; i++) {
      if (chunk[i] == 3)  // ^C
        process.exit();
    }
}, 100);

Thanks, useful.
