Vertx event bus reconnect

I would like to use vertx eventbus from Javascript client (mainly smartphones). My problem is when I send the phone to standby, the eventbus disconnects after a couple of seconds and doesn't reconnect after wake up. I try to reconnect in eventbus onclose(), but it doesn't always work. Any ideas?

This functionality has been added to working version of vert.x, but is not yet official. However, you can import and use vertx-eventbus.js :

https://github.com/vert-x3/vertx-web/pull/660

After you initialize the EventBus with e.g. var eb = new EventBus("/eventbus");, you can enable it with eb.enableReconnect(true);

Instead of trying reconnection only once, why don't you try to reconnect in a loop:

eventBus.onclose = function {
 while(state != vertx.EventBus.OPEN) {
   setInterval(function(){
      // Recreate an eventbus object and re-register all callbacks included this one 
      initialiseEventbus()
   },3000);
 }
}

The above is not the most elegant solution, but unfortunately there's no (re)connect method to call on vertxbus.js, nor a default automatic reconnection strategy. That's a pity, but I'm sure the dev team would happy to accept a ticket on this.
