In newer NodeJS versions, you can pass a callback to .write(), which will be called once the data is flushed:

sys.stdout.write('some data', () => {
  console.log('The data has been flushed');
});

This is exactly the same as checking .write() result and registering to the drain event:

let write = sys.stdout.write('some data');
if (!write) {
  sys.stdout.once('drain', () => {
    console.log('The data has been flushed');
  });
}
