You first need to open the standard input stream. Try something like this snippet:

// We start listening for input:
const stdin = process.openStdin();
let content = '';

stdin.addListener('data', d => {
  content += d.toString();
});

stdin.addListener('end', () => {
  console.info(`Input: ${content}`);
});
