#node-apn

A Node.js module for interfacing with the Apple Push Notification service.

Features

Fast
Maintains a connection to the server to maximise notification batching and throughput.
Enhanced binary interface support, with error handling
Automatically sends unsent notifications if an error occurs
Feedback service support
Complies with all best practises laid out by Apple

Installation

Via npm:

$ npm install apn

As a submodule of your project (you will also need to install q)

$ git submodule add http://github.com/argon/node-apn.git apn
$ git submodule update --init

Quick Start

This is intended as a brief introduction, please refer to the documentation in doc/ for more details.

Load in the module

var apn = require('apn');

Connecting

Create a new connection to the APN gateway server using a dictionary of options. If you name your certificate and key files appropriately (cert.pem and key.pem) then the defaults should be suitable to get you up and running, the only thing you'll need to change is the gateway if you're in the sandbox environment.

	var options = { "gateway": "gateway.sandbox.push.apple.com" };

	var apnConnection = new apn.Connection(options);

Help with preparing the key and certificate files for connection can be found in the wiki

Sending a notification

To send a notification first create a Device object. Pass it the device token as either a hexadecimal string, or alternatively as a Buffer object containing the token in binary form.

var myDevice = new apn.Device(token);

Next, create a notification object, set the relevant parameters (See the payload documentation for more details.) and use the pushNotification method on the connection to send it.

var note = new apn.Notification();

note.expiry = Math.floor(Date.now() / 1000) + 3600; // Expires 1 hour from now.
note.badge = 3;
note.sound = "ping.aiff";
note.alert = "\uD83D\uDCE7 \u2709 You have a new message";
note.payload = {'messageFrom': 'Caroline'};

apnConnection.pushNotification(note, myDevice);

The above options will compile the following dictionary to send to the device:

{"messageFrom":"Caroline","aps":{"badge":3,"sound":"ping.aiff","alert":"\uD83D\uDCE7 \u2709 You have a new message"}}

Setting up the feedback service

Apple recommends checking the feedback service periodically for a list of devices for which there were failed delivery attempts.

Using the Feedback object it is possible to periodically query the server for the list. Many of the options are similar to that of Connection.

Attach a listener to the feedback event to receive the output as two arguments, the time returned by the server (epoch time) and a Buffer object containing the device token - this event will be emitted for each device separately. Alternatively you can enable the batchFeedback option and the feedback event will provide an array of objects containing time and device properties.

var options = {
	"batchFeedback": true,
	"interval": 300
};

var feedback = new apn.Feedback(options);
feedback.on("feedback", function(devices) {
	devices.forEach(function(item) {
		// Do something with item.device and item.time;
	});
});

By specifying a time interval (in seconds) Feedback will periodically query the service without further intervention.

More information about the feedback service can be found in the feedback service documentation.

Debugging

If you experience difficulties sending notifications or using the feedback service you can enable debug messages within the library by running your application with DEBUG=apn or DEBUG=apnfb set as an environment variable.

You will need the debug module which can be installed with npm install debug.

You are encouraged to read the extremely informative Troubleshooting Push Notifications Tech Note in the first instance, in case your query is answered there.

Support

If you have any questions or difficulties working with the module, the node-apn Google group should be your first port of call.

Please include as much detail as possible - especially debug logs, if the problem is reproducible sample code is also extremely helpful. GitHub Issues should only be created for verified problems and enhancements, this will allow them to be tracked more easily.
