Description
I need your help after I upgrade the dependencies to "socket.io": "^4.6.1" ...I am getting an error in the console of the browser : GET http://127.0.0.1:5500/socket.io/?EIO=4&transport=polling&t=OVI3WYK 404 (Not Found)
below is my code
my server:
var http = require('http');
var fs = require('fs');
var index = fs.readFileSync( 'index.html');
const { SerialPort } = require('serialport')
const { ReadlineParser } = require('@serialport/parser-readline')
const parser = new ReadlineParser({ delimiter: '\r\n' });
var port = new SerialPort(
{ path: 'COM3', baudRate: 9600 , dataBits: 8, parity: 'none', stopBits: 1, flowControl: false}
);
port.pipe(parser);
var app = http.createServer(function(req, res) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.end(index);
});
var io = require('socket.io')(app);
io.on('connection', function(socket) {
socket.on('lights',function(data){
console.log( data );
port.write( data.status );
});
});
app.listen(5500);
my index.html:
<!doctype html>

var socket = io();
document.getElementById('lightOn').onclick = function() {
socket.emit('lights', { "status":"1" });
};
document.getElementById('lightOff').onclick = function(){
socket.emit('lights', { "status":"0" });
};
