SockJS Event Bus bridge with WebRTC for Vert.x 3.3.3

vertx3-eventbus-client-webrtc and vertx3-eventbus-webrtc-helper

Automatically upgrades to low-latency UDP data channel ( RTCDataChannel ) for browser to browser communication when available.

All normal Event Bus client methods work (send, publish, register, unregister)

New:

registerStatusHandler( address, headers, callback )

Is fired when:

1. the bridge has a client unregister that address
2. the bridge has a client register that address (not yet)

This is useful for knowing when another client disconnects. (ie. if you give clients their own address)

passes a status object { listenerRemoved: true }

to remove:

unregisterStatusHandler( address, headers, callback )

to use

vertx3-eventbus-webrtc-helper is needed on the server side

var webRTCHelper = require( 'vertx3-eventbus-webrtc-helper' );

pass it the eventbus

webRTCHelper.init( eb );

add bridge address options to inbound and outbound

    { "addressRegex" : "webrtc\\..+" }

a handle must be added to sockJSHandler for bridge events

sockJSHandler.bridge( opts, webRTCHelper.bridgeEvent );

to run the example chatApp you will want to npm install in the vertx3-eventbus-client-webrtc dir and in the happyChat dir contained within examples.

then from happyChat dir run ( default port 8090 )

npm start

atm you can add #nowebrtc to url to disable WebRTC in browser
