Tcp server cannot emit 'end' or 'close' event when 'data' event isn`t listened

• Version: 14.14
• Platform: Windows
• Subsystem: Windows 10

Server code:

const server = createServer((socket) => {
  socket.on('end', () => {
    console.log('end');
  });
  socket.on('close', () => {
    console.log('close');
  });

  // Without this handler 'end' and 'close' event cannot be emited.
  // socket.on('data', (data) => {
      // console.log(data.toString());
  // });
})
server.listen(8080);

Client code:

const client = createConnection({ port: 8080 }, () => {
  client.end('Bye');
});

If there is not 'data' event handler in server code, client.end cannot emit 'end' or 'close' event of server.

That's expected, you have to read all the buffered data before the 'end' event is emitted. If you don't want to add a listener for the 'data' event, you can resume the socket.

socke.on('end', () => {
  console.log('end');
});

socket.resume();
