Code

var app = require('express')();
const fs = require('fs');
const config = require('./config-local.json');
const options = {
    key: fs.readFileSync(config.keyPath),
    cert: fs.readFileSync(config.certPath)
};
var server = require('https').createServer(options, app);
var io = require('socket.io')(server);
var redis = require('redis');
var numClients = 0;
server.listen(3345);
io.on('connection', function (socket) {
    numClients++;
    console.log("new client connected");
    var redisClient = redis.createClient();
    redisClient.subscribe('channel1');
    redisClient.subscribe('channel2');
    redisClient.subscribe('channel3');
    redisClient.subscribe('channel4');
    redisClient.subscribe('channel5');
    redisClient.subscribe('channel6');
    redisClient.subscribe('channel7');
    redisClient.subscribe('channel8');
    redisClient.subscribe('channel9');
    redisClient.on("message", function(channel, message) {
        console.log("New message: " + message + ". In channel: " + channel);
        socket.emit(channel, message);
    });
    socket.emit('online', numClients);
    socket.on('disconnect', function() {
        numClients--;
        socket.emit('online', numClients);
        console.log("client disconnected", numClients);
        redisClient.quit();
    });
});
