How to connect to the server in websockets (socket.io)?

Question

Node.js

I have a Heroku site and I know my IP. The server is running on my PC. How to connect socket.io on a website to it?

<script src="/socket.io/socket.io.js"></script>
  <script>
    let socket = io(); // может тут надо написать? если да, то как примерно должно выглядеть?

Answer 1

const socket = io('https://' + '255.255.1.1' + ':' + 443);

Answer 2

On the client. the url at which the socket is available, usually in the form ip:port or domain:port; port is usually 3000, but can be anything. It is not necessary to send an object, it is enough to track the events transmitted to emit as the first parameter. The syntax for emit and on is the same on the server and client.

var socket_url = "yoursite.ru:3000";
var socket = io.connect (socket_url);

// Отправка чего-то на сервер
socket.emit ('Privet',
{
  param1: 'kaknikruti',
  param2: 12345
  // и так далее
});

// Приём с сервера
socket.on ('Otvet', function (data)
{
  alert (data.otvet);
});

Judging by the description, the client in this case is your cloud server. But the procedure should not be different.
