meteor - get all subscriber session handles for a publisher method

Question

I want to broadcast NON-MONGO-DB data from a server publisher to client collections. Currently I save all registered subscriber handles to use those for posting the data

Answer 1

As informed by @laberning I used for now the "undocumented" meteor connections.

You can post to all subscribers of a publishing method like:

// publish updated values to all subscribers
function publish_to_all_subscribers(subscription_name, id, data) {
  _.each(Meteor.server.stream_server.open_sockets, function(connection) {
    _.each(connection._meteorSession._namedSubs, function(sub) {
      if (sub._name == subscription_name) {
        sub.insert(subscription_name, id, data);
      }
    })
  });
}

// create stream publisher
Meteor.publish('stream', function(){
  // set ready
  this.ready();
});

...
// use publishing somewhere in your app
publish_to_all_subscribers('stream', Random.id(), {msg: "Hello to all"});
...

Maybe this might work for you: https://stackoverflow.com/a/30814101/2005564

You could get the connections via var connections = Meteor.server.stream_server.open_sockets; but as looshi said this might break with a future meteor update as it is not part of the public API...
