Listen to the connection status and if the connection is lost and reestablished they automatically resubscribe (you can see the java util here https://github.com/deepstreamIO/deepstream.io-client-java/blob/master/src/main/java/io/deepstream/UtilResubscribeNotifier.java and the javascript one here https://github.com/deepstreamIO/deepstream.io-client-js/blob/master/src/utils/resubscribe-notifier.js

The callback would be as follows: https://github.com/deepstreamIO/deepstream.io-client-js/blob/master/src/event/event-handler.js#L222
