Socket.io python server

Question

I am using https://github.com/invisibleroads/socketIO-client to have my Node.JS server communicate with a Python Backend.

However, this is a bit tricky because I actually want to use my Python as a backend, and it makes more sense to have Python act as a server and Node.JS act as a client. Ideally, Node.JS code initiates the connection to the Python code, and Python Code returns something.

Although there is a socket.io-client library for Node.JS, I couldn't find a simple socket.io server library for Python.

As an alternative, how can I have the socket.io server initiate the message (i.e. emit()) to the client?

Solution 1

Oops, reading the bottom of https://github.com/learnboost/socket.io/wiki reveals that

http://github.com/abourget/gevent-socketio

does the trick. There is also a https://github.com/evanw/socket.io-python library that is deprecated because of an outdated socket.io

Solution 2

gevent-socketio is no longer actively supported (last commit Jan 2014).

The new player is Flask-SocketIO:
