PY4WEB socketIO

[António Ramos]

hello , just asking if py4web will have the ability like flask to have a socket  as simple as ...

Regards

@socketio.on('my event')
def handle_my_custom_event(arg1, arg2, arg3):
    print('received args: ' + arg1 + arg2 + arg3)

also rooms ...

It would be trivial to implement it like flask does. 

You can do it right now using the bottlepy way:

https://pypi.org/project/bottle-websocket/

or

https://github.com/marlboromoo/bottle-socketio-example

py4web uses bottle under the hood.

The problem is that I would like something better than that.

I am not convinced it would work well in a cloud setting o when you have servers behind a load balancer.

Imagine you have two chat clients connected to two servers. If your client posts a chat message, how does one server notify the other server to notify the other client? This is the hard problem to solve. I am not interests in toy examples. py4web will have this.

I was not expecting less than that from Massimo :)

Massimo, maybe zeroMQ can be good for you.
