    node-vortex

    A Node.js module for PrismTech Vortex

    Compiling Coffee Script files

    The source of the module is written in CoffeeScript, to compile them to JavaScript:

    grunt compile

    To use

    var vortex = require("node-vortex");

    Create an instance of the Vortex client

    var client = new vortex.runtime.Runtime();

    Connecting Vortex client

    var vortexUrl = "ws://demo-lab.prismtech.com:9000"; // replace if using a private Vortex instance
    var vortexCredentials = "uid:pwd"; // replace if using a custom access control plugin for Vortex
    client.connect(vortexurl, vortexCredentials);

    Listening for a successful connection

    client.onconnect = function() {
        // place logic for a successful connection here
        console.log("Connected");
    };

    Creating a topic

    var domain = 0; // override with the specific domain being used
    var topicName = "PhoneSensorData"; // the name of the topic subscribing to
    var tQos = new vortex.TopicQos(); // can be customized for more complex scenarios
     
    var topic = new vortex.Topic(domain, topicName, tQos);
     
    client.registerTopic(topic);

    To listen for the registration of a topic to complete

    topic.onregistered = function() {
        // do something when the topic is registered
    };

    Subscribing to data updates

    var drQos = new vortex.DataReaderQos(); // can be customized for more complex scenarios
    var sub = new vortex.DataReader(client, topic, drQos);
     
    // to listen for a successful subsription
    sub.onconnect = function() {
        // handle succesfful subscription
    };
     
    // to listen for data updates
    sub.addListener(function(data) {
        // handle data update
    });

    Publishing data updates

    var dwQos = new vortex.DataWriterQos(); // can be customized for more complex scenarios
    var pub = new vortex.DataWriter(client, topic, drQos);
     
    // to listen for a successful connection
    pub.onconnect = function() {
        // handle succesfful connection
    };

    To actually publish data updates

    var data = {}; // data should be some JSON object
    pub.send(data);
