Good evening!
I do not know if it is possible to implement the following situation: I have a html page that is a monitor (has the last number called), on the second page html, the user can click to request the next number. I can even exchange information via socket, but only with the page that was clicked, I would have to update the other page that is the monitor. If you can not do this, you would have to check the endpoint at any time to see if the number has changed. Any suggestions, even if it's not via socket?
Current solution that did not work:
server.js
var http = require('http')
var express = require('express')
var socketio = require('socket.io')
var app = express(server)
var server = http.Server(app)
var io = socketio(server)
app.get('/', function(req, res){
console.log('Passei aqui!!!');
req.socket.on('login_monitor', function(data, callback) {
req.socket.join('monitor');
callback();
});
res.sendFile(__dirname + '/monitor.html');
});
app.get('/teste', function(req, res){
console.log('TESTE!!!');
io.on('connection', function(socket){
socket.on('echo', function(data){
socket.emit('echo', 'Servidor--->');
console.log(data);
socket.on('echo', function(data) {
socket.emit('echo', 'Servidor--->'); //envia para quem invocou o echo
io.to('monitor').emit('echo', 'Funcionou!!!!!'); //envia para o monitor
});
});
});
res.sendFile(__dirname + '/index.html');
});
io.on('connection', function(socket){
socket.on('echo', function(data){
socket.emit('echo', 'Servidor--->');
console.log(data);
});
});
server.listen(8080);
