    #get chat hub
    chat = connection.register_hub('chat')

    #start a connection
    connection.start()

    #create new chat message handler
    def print_received_message(data):
        print('received: ', data)

    def print_topic(topic, user):
        print('topic: ', topic, user)

    #create error handler

    #receive new chat messages from the hub
    chat.client.on('newMessageReceived', print_received_message)

    #change chat topic
    chat.client.on('topicChanged', print_topic)

    #process errors
    connection.error += print_error

    #start connection, optionally can be connection.start()
