I'm encountering a problem with establishing a connection between two users. I have already installed express and socket.io, but for some reason, the message is not getting through to the receiver's end. The code seems to be running fine as I can open the website without any issues. However, when I try to send a message from one page, it doesn't show up at the recipient's end.
var app = require('express')();
var http = require('http').createServer(app);
var io = require('socket.io')(http);
app.get('/chat', (req, res) => {
res.sendFile(__dirname + '/chat.html');
});
io.on('connection', (socket) => {
console.log('User Online');
socket.on('codeboard-message', (msg) => {
console.log('message: ' + msg);
socket.broadcast.emit('message-from-others', msg);
});
});
var server_port = process.env.YOUR_PORT || process.env.PORT || 3000;
http.listen(server_port, () => {
console.log('listening on *:' + server_port);
});<html>
