Subscribe to dynamic laravel channel via redis - php

Question

I want to broadcast an event on dynamic channels in larvel.
To broadcast on a specific channel I tried this tutorial and all things worked fine.
This is my event:
class ChatNewMessage implements ShouldBroadcast
{
use InteractsWithSockets, SerializesModels;
public $targetUsers;
public $message;
public function __construct ($message)
{
$this->targetUsers = $message->chat->users->pluck('user_id');
/*This is an array of user that are subscribed to a chat*/
$this->message = $message;
}
public function broadcastOn ()
{
$userChannels = [];
foreach ($this->targetUsers as $id) {
$userChannels[] = 'user-channel.' . $id;
}
return $userChannels;
}
}
And this is js code to get events that occurred for a user by user_id=5 :
var socketURL = 'http://127.0.0.1:3000';
var socket = io(socketURL);
socket.on('user-channel.5:App\\Events\\ChatNewMessage', function (event) {
alert(event.data);
});
And this is js code that runs node :
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var Redis = require('ioredis');
var redis = new Redis();
// redis.subscribe('user-channel.5', function (err, count) {});
redis.psubscribe('*', function(err, count) {});
redis.on('message', function (channel, message) {
console.log('Message Received: ' + message);
message = JSON.parse(message);
io.emit(channel + ':' + message.event, message.data);
});
http.listen(3000, function () {
console.log('Listening on Port 3000');
});
redis.on("error", function (err) {
console.log(err);
});
As you can see I used redis.psubscribe('*', function(err, count) {}); to subscribe to all channels like user-channel.1 , user-channel.2 , user-channel.3 and so on.
But that does not work.
Of course when I used an static channel name on redis like redis.subscribe('user-channel.5', function (err, count) {}); that all things work.
I do not know what is problem and how can I subscribe to channels that are created dynamically.
I'm using laravel 5.2.

Finally I used below and all things worked fine :
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var Redis = require('ioredis');
var redis = new Redis();
redis.psubscribe('*', function(err, count) {});
redis.on('pmessage', function(subscribed, channel, message) {
console.log(channel);
message = JSON.parse(message);
io.emit(channel + ':' + message.event, message.data);
});
http.listen(3000, function () {
console.log('Listening on Port 3000');
});
redis.on("error", function (err) {
console.log(err);
});
