You can use PUBSUB NUMSUB channel1 OR PUBSUB NUMSUB channel2 and get reply about the number of subscribers for the specified channel.

I can achieve this with something like:

redis_client.multi().client(['list']).exec(function(err, results) {
  var pairs = results[0].split(' ');
  pairs.forEach(function(pair){
    var kv = pair.split('=');
    if (kv[0] == 'name' && kv[1] == constants.REDIS_SUBSCRIBER_NAME)
      found = true;
  });
  if (found) // some logic
  else // some logic
});
