Mutliple nodejs server communicating with each other with socket.io-redis not receiving event

I managed to connect two nodejs server to Redis using socket.io-redis. Using "redis-cli monitor" I can see events being received on Redis butit dosent go all the way. It is like I'm missing something.

here how both server look like (with the numbers 1 and 2 being reversed)

socket.on('action', function(data) {
    socket.broadcast.to(3).emit('toServer1', "message from server 2")
})    
socket.on('toServer2', function(msg) {
    console.log('msg', msg)
})

And here is what I see on Redis monitor when the event action is triggered with a button.

They both also subscribe to the right channels as well:

Am i missing something. Is there something else it has to do to fetch/receive the events from redis?

Solution

  • Okay... I figured it out.

    I'm suppose to catch the event on the client side and not the server side. I don't know if previous versions of socket.io-redis was different but for some reason I have memory of receiving the event on the server.
