I'm trying to create a WebSocket from the main.js in Electron (port 9999):
const { app, BrowserWindow } = require('electron');
const http = require('http');
const WebSocket = require('ws');
Stream = require('node-rtsp-stream')
require('electron-reload')();
function createWindow () {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
nodeIntegration: true
}
});
win.loadFile('index.html');
}
function startServer () {
const port = 9999;
const server = http.createServer();
const wss = new WebSocket.Server({ server });
wss.on('connection', function connection(ws) {
ws.on('message', function incoming(message) {
console.log('received: %s', message);
});
console.log('Llego aquí');
ws.send('something');
});
}
app.whenReady().then(startServer).then(createWindow);
Then, I want to read the message sent from the server on index.html (listening port 9999):
<!DOCTYPE html>
<html>
<head>
<meta charset = 'UTF-8'>
</head>
<body>
<h1>App</h1>
</body>
<script>
var exampleSocket = new WebSocket("wss://localhost:9999", "protocolOne");
exampleSocket.onmessage = function (event) {
console.log(event.data);
}
</script>
</html>
The problem is that I'm getting the following error:
index.html:22 WebSocket connection to 'wss://localhost:9999/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
What I'm missing?
