Connect to Rcon using WebSockets (ws)

Question

I'm new to using web sockets in nodejs in my electronjs project. My goal is to connect to the connection my server is running, I have everything setup correctly, the port, password, and localhost, all seemed to work using another package. But when I try to create this on my own, I can't seem to get this to work.

const WebSocket = require('ws');

serverip = 'localhost';
serverport = 25575;
serverpass = 'password';
const ws = new WebSocket('ws://' + serverip + ':' + serverport + '/' + serverpass + '/');

ws.on('open', function open() {
    ws.send('/kick Player');
});

ws.on('message', function incoming(data) {
    console.log(data);
});

ws.on('close', function close() {
    console.log('disconnected');
});

What I have above is what I have so far, my console from the server I'm trying to connect to says that it is getting a connection from my pc, but doesn't relay any info besides that.

Server Output:
Rcon connection from: /127.0.0.1

This is an error I am getting in my electronjs console:

Uncaught Error: socket hang up
    at createHangUpError (_http_client.js:334)
    at Socket.socketOnEnd (_http_client.js:435)
    at Socket.emit (events.js:199)
    at endReadableNT (_stream_readable.js:1141)
    at processTicksAndRejections (internal/process/task_queues.js:81)

Any help would be greatly appreciated.

Answer 1

A couple of issues with this as I'm trying to WebSocket a simple Source RCON myself. Fortunately, my code below compiles well.

var serverip = 'RconHost';
var serverport = 28016;
var serverpass = 'RconPassword';
    
const ws = new WebSocket('ws://' + serverip + ':' + serverport + '/' + serverpass);
console.log(ws);
    
ws.onopen = function(event) {
    console.log("WebSocket is onopen now.");
};
    
ws.onmessage = function(event) {
    console.log("WebSocket is onmessage now.");
};
    
ws.onclose = function(event) {
    console.log("WebSocket is onclose now.");
};

Uncaught Error: socket hang up at createHangUpError (_http_client.js:334) at Socket.socketOnEnd (_http_client.js:435) at Socket.emit (events.js:199) at endReadableNT (_stream_readable.js:1141) at processTicksAndRejections (internal/process/task_queues.js:81)

... Looks like an unreachable host. The trailing forward slash in the URL was problematic.

ws:// => wss://

const ws = new WebSocket('wss://' + serverip + ':' + serverport + '/' + serverpass + '/');

const ws = new WebSocket('ws://' + serverip + ':' + serverport + '/' + serverpass + '/');
