Why is the socket closed immediately after receiving a response?

Question

Node.js

There is an example client in Node.js

var net = require('net');

var client = new net.Socket();
client.connect(3333, 'localhost', function() {
    console.log('Connected');
    client.write('Hello, server! Love, Client.');
});
client.on('data', function(data) {
    console.log('Received: ' + data.toString());
    //client.destroy();
});

client.on('close', function() {
    console.log('Connection closed');
});

After receiving the message, the socket is closed, although client.destroy(); commented out. Why is this happening?

Answer 1

socket.setKeepAlive([enable][, initialDelay])#
Enable/disable keep-alive functionality, and optionally set the initial delay before the first keepalive probe is sent on an idle socket. enable defaults to false.

I assume you are talking about this. Good luck.
