Sending apple push notification to multiple users from node.js in one connection

I've seen node module "node-apn" but I don't see how could I send same notification to multiple users in one connection? I've also seen that it is possible to do in PHP but I am using node.js

With node-apn v1.3.x (a highly recommended upgrade) you can send an identical notification to many devices without needing the loop at all. The module will automatically take care of the intricacies around sending one notification to multiple devices for you.

// Instantiate a new message
// and set message defaults
var note = new apns.Notification();
note.expiry = Math.floor(Date.now() / 1000) + 3600; // Expires 1 hour from now.
note.badge = 3;
note.sound = "ping.aiff";
note.alert = "You have a new message";
note.payload = {'messageFrom': 'Caroline'};

// List of user tokens
var userTokens = ['token1', 'token2', 'token3'];
// Send the message
apnsConnection.pushNotification(note, userTokens);
