requester.js

var diffusion = require('diffusion');

// Connect to Reappt with requester credentials
diffusion.connect({ 
    host   : 'approvingBoldDaVinci.us.reappt.io',
    port   : 443,
    secure : true,
    principal : 'requester',
    credentials : 'retseuqer'
}).then(function(session) {
    

    // Subscribe to the "open/cats" topic
    var openSub = session.subscribe('open/cats').on({
        subscribe : function(details, topic) {
            console.log('Subscribed to topic: ' + topic);
        },
        update : function(value, topic) {
            console.log(topic + ' updated with value: ' + value);
        },
        error : function(error) {
            console.log(error);
        }
    });

    // Subscribe to the "closed/cats" topic
    var closedSub = session.subscribe('closed/cats').on({
        subscribe : function(details, topic) {
            console.log('Subscribed to topic: ' + topic);
        },
        update : function(value, topic) {
