Getting started with node-ivy

node-ivy is a pure Javascript implementation of the Ivy Software Bus (http://www.eei.cena.fr/products/ivy/).

Install node-ivy

npm install node-ivy

Create an ivy bus

    var IvyBus = require('node-ivy');
    ...
    var ivy = new IvyBus("MyApp", "127.255.255.255", 2010);
    ...
    ivy.start();

Subscribe to a given type of message

    var subId = ivy.subscribe(/myregex ([^ ]*) (.*)/, function(params){
        console.log(params);
    });

• The regex describes the format of the messages the user wants to listen to.
• Only messages that match the given regex will trigger the callback.
• params is an array containing the result of every catch block defined in the regex.

Removing a previously set subscription

    ivy.unsubscribe(subId);

Send a message on the bus

    ivy.send("mymessage");

Listen for other peers on the bus

    ivy.on('peerConnected', function(peer){
        console.log("peer "+peer.name+" connected !");
    });

    ivy.on('peerQuit', function(peer){
        console.log("peer "+peer.name+" disconnected !");
    });

Quit the bus

    ivy.stop();
