stream-no-data-listener.js

const net = require('net');

net.createServer((socket) => {
  // We add an 'end' listener, but never consume the data.
  socket.on('end', () => {
    // It will never get here.
    socket.end('The message was received but was not processed.\n');
  });

}).listen(1337);

const client = net.connect({"host": "localhost", "port": 1337});
client.on("connect", socket => {
  // In fact, we DO enter the 'end' listener after this call!
  socket.end();
});
