Я создал (я скопировал) сервер чата с помощью Node.js и сервер находится на моем LocalHost: 127.0.0.1, только я могу использовать чат, но я хочу, чтобы кто-нибудь может использовать сервер слишком , так что я хочу знать, как поставить этот чат сервер в моем реальном сервере: http://sistema.agrosys.com.br/sistema/padrao/HTML5/WebSocket/
И: http://calnetaskmanager.herokuapp.com/Как я могу сделать свой сервер доступным для всех?
Но я сейчас не как поставить мой чат-server.js в мой Heroku Сервер.
Что мне делать, чтобы сделать это возможным.
Заранее спасибо
Если вы хотите увидеть, что происходит: client side on my server
Client Side:
$(function() {
"use strict";
// for better performance - to avoid searching in DOM
var content = $('#content');
var input = $('#input');
var status = $('#status');
// my color assigned by the server
var myColor = false;
// my name sent to the server
var myName = false;
// if user is running mozilla then use it's built-in WebSocket
window.WebSocket = window.WebSocket || window.MozWebSocket;
// if browser doesn't support WebSocket, just show some notification and exit
if (!window.WebSocket) {
content.html($('<p>', {
text: 'Sorry, but your browser doesn\'t ' + 'support WebSockets.'
}));
input.hide();
$('span').hide();
return;
}
// open connection
var connection = new WebSocket('ws://127.0.0.1:1337');
connection.onopen = function() {
// first we want users to enter their names
input.removeAttr('disabled');
status.text('Choose name:');
};
connection.onerror = function(error) {
// just in there were some problems with conenction...

Просто укажите домен на ip-адрес вашего сервера. Или выдайте IP-адрес своего сервера. –
Как мне это сделать? Я действительно нуб об этом! –
