Can't create socket server from http module - node.js

Question

I wanna create socket server like a Socket.io because socket.io can't work with Corona SDK. So I need custom socket server. I create socket server with using net module and it is work good. But I need using http module because I write REST API. I try create sample socket server from http module but have errors.
var net = require('net');
var HOST = 'localhost';
var PORT = 9999;
var server = require('http').createServer(function(request, response) {
response.end('Hello from server');
});
server.on('connection', function(socket) {
socket.on('data', function(data) {
data = data.toString('utf-8');
console.log(data);
socket.write('Hello from server');
});
socket.on('error', function(error) {
console.log(error);
});
});
server.listen(PORT, HOST);
var client = new net.Socket();
client.connect(PORT, HOST, function() {
console.log('CONNECTED TO: ' + HOST + ':' + PORT);
client.write('I am Chuck Norris!');
});
client.on('data', function(data) {
console.log('DATA: ' + data);
client.destroy();
});
client.on('close', function() {
console.log('Connection closed');
});
If I run this script I got error:
CONNECTED TO: localhost:9999
I am Chuck Norris!

Connection closed
Why this happed and how fix this?
Additional to answer
I add HTTP headers to request and all works good!
Code sample below:
var http = require('http');
var net = require('net');
var express = require('express');
var HOST = 'localhost';
var PORT = 9999;
var app = express();
var server = http.Server(app);
app.get('/', function (req, res) {
res.send('Hello World!fff');
});
server.listen(PORT, HOST);
server.on('connection', function(socket) {
socket.on('data', function(data) {
data = data.toString('utf-8');
console.log(data);
socket.write('Hello from server');
});
socket.on('error', function(error) {
console.log(error);
});
socket.on('end', function() {
console.log('Socket end');
});
});
// Client
var client = new net.Socket();
client.connect(PORT, HOST, function() {
console.log('CONNECTED TO: ' + HOST + ':' + PORT);
var messagae = '' +
'GET /' +
'Host:localhost:9999' +
'Content-Type:text/plain;charset=windows-1251' +
'Content-Length:6' +
'Connection:Keep-Alive;' +
'Hello!';
client.write(messagae);
});
client.on('data', function(data) {
console.log('DATA: ' + data);
});
client.on('close', function() {
console.log('Connection closed');
});

Answer 1

at TCP.onread (net.js:560:20) bytesParsed: 0, code: 'HPE_INVALID_METHOD' }
Since you have explicitly created a HTTP server this server is expecting a HTTP request. But you are just sending "I am Chuck Norris!" which is definitely not a HTTP request. Therefore the server closes the connection.
To send a HTTP request you might use http.request. Alternatively you can study the HTTP standard and build a proper HTTP request yourself.

Answer 2

Your client was disconnect
var net = require('net');
var HOST = 'localhost';
var PORT = 9999;
var server = net.createServer(function(socket) {
socket.write('Echo server\r\n');
socket.on('data', function(data){
console.log(data);
textChunk = data.toString('utf8');
console.log(textChunk);
socket.write("================");
});
});
server.listen(PORT, '127.0.0.1');
server.listen(PORT, HOST);
var client = new net.Socket();
client.connect(PORT, HOST, function() {
console.log('CONNECTED TO: ' + HOST + ':' + PORT);
client.write('I am Chuck Norris!');
});
var i = 0;
client.on('data', function(data) {
console.log('Received: ' + data);
i++;
if(i==2)
client.destroy();
} );
client.on('close', function() {
console.log('Connection closed');
});
