Node Push Notifications

A node.js module for interfacing with Apple Push Notification, Google Cloud Messaging, Amazon Device Messaging services.

Installation

npm install node-pushnotifications --save

Features

Powerful and intuitive.
Multi platform push notifications.
Automatically detects destination device type.
Unified error handling.
Written in ES6, compatible with ES5 through babel transpilation.

Usage

1. Import and setup push module:

Include the settings for each device type. You should only include the settings for the devices that you expect to have. I.e. if your app is only available for android or for ios, you should only include gcm or apn respectively.

const settings = {
    gcm: {
        id: null,
        ...
    },
    apn: {
        token: {
            key: './certs/key.p8', // optionally: fs.readFileSync('./certs/key.p8')
            keyId: 'ABCD',
            teamId: 'EFGH',
        },
        ...
    },
    adm: {
        client_id: null,
        client_secret: null,
        ...
    }
};
const PushNotifications = require('node-pushnotifications');
const push = new PushNotifications(settings);

GCM options: see node-gcm
APN options: see node-apn
ADM options: see node-adm

iOS: It is recomended to use provider authentication tokens. You need the .p8 certificate that you can obtain in your account membership. You should ask for an Apple Push Notification Authentication Key (Sandbox & Production) or Apple Push Notification service SSL (Sandbox & Production). However, you can also use certificates. See node-apn to see how to prepare cert.pem and key.pem.

2. Define destination device ID. You can send to multiple devices, independently of platform, creating an array with different destination device IDs.

// Single destination
const registrationIds = 'INSERT_YOUR_DEVICE_ID';
 
// Multiple destinations
const registrationIds = [];
registrationIds.push('INSERT_YOUR_DEVICE_ID');
registrationIds.push('INSERT_OTHER_DEVICE_ID');

Android: If you provide more than 1.000 registration tokens, they will automatically be splitted in 1.000 chunks (see this issue in gcm repo)

3. Create a JSON object with a title and message and send the notification.

Both title and body fields are required (or alert for ios). The other fields are optional (see below how the message is created for each device type):

const data = {
    title: 'New push notification', // REQUIRED
    body: 'Powered by AppFeel', // REQUIRED
    topic: '', // REQUIRED for apn and gcm for ios
    custom: {
        sender: 'AppFeel',
    },
    priority: 'high', // gcm, apn. Supported values are 'high' or 'normal' (gcm). Will be translated to 10 and 5 for apn. Defaults to 'high'
    collapseKey: '', // gcm for android, used as collapseId in apn
    contentAvailable: true, // gcm, apn. node-apn will translate true to 1 as required by apn.
    delayWhileIdle: true, // gcm for android
    restrictedPackageName: '', // gcm for android
    dryRun: false, // gcm for android
    icon: '', // gcm for android
    tag: '', // gcm for android
    color: '', // gcm for android
    clickAction: '', // gcm for android. In ios, category will be used if not supplied
    locKey: '', // gcm, apn
    bodyLocArgs: '', // gcm, apn
    titleLocKey: '', // gcm, apn
    titleLocArgs: '', // gcm, apn
    retries: 1, // gcm, apn
    encoding: '', // apn
    badge: 2, // gcm for ios, apn
    sound: 'ping.aiff', // gcm, apn
    alert: {}, // apn, will take precedence over title and body
    // alert: '', // It is also accepted a text message in alert
    titleLocKey: '', // apn and gcm for ios
    titleLocArgs: '', // apn and gcm for ios
    launchImage: '', // apn and gcm for ios
    action: '', // apn and gcm for ios
    category: '', // apn and gcm for ios
    mdm: '', // apn and gcm for ios
    urlArgs: '', // apn and gcm for ios
    truncateAtWordEnd: true, // apn and gcm for ios
    mutableContent: 0, // apn
    threadId: '', // apn
    expiry: Math.floor(Date.now() / 1000) + 28 * 86400, // seconds
    timeToLive: 28 * 86400, // if both expiry and timeToLive are given, expiry will take precedency
    consolidationKey: 'my notification', // ADM
};
 
// You can use it in node callback style
push.send(registrationIds, data, (err, result) => {
    if (err) {
        console.log(err);
    } else {
        console.log(result);
    }
});
 
// Or you could use it as a promise:
push.send(registrationIds, data)
    .then((results) => { ... })
    .catch((err) => { ... });

err will be null if all went fine, will return the error otherwise.
result will contain an array with the following objects (one object for each device type found in device registration id's):

[
    {
        method: 'gcm', // The method used send notifications and which this info is related to
        multicastId: [], // (only Android) Array with unique ID (number) identifying the multicast message, one identifier for each chunk of 1.000 notifications)
        success: 0, // Number of notifications that have been successfully sent. It does not mean that the notification has been deliveried.
        failure: 0, // Number of notifications that have been failed to be send.
        message: [{
            messageId: '', // (only for android) String specifying a unique ID for each successfully processed message or undefined if error
            regId: value, // The current registrationId (device token id). Beware: For Android this may change if Google invalidates the previous device token. Use "originalRegId" if you are interested in when this changed occurs.
            originalRegId: value, // (only for android) The registrationId that was sent to the push.send() method. Compare this with field "regId" in order to know when the original registrationId (device token id) gets changed.
            error: new Error('unknown'), // If any, there will be an Error object here
        }],
    },
    {
        method: 'apn',
        ... // Same structure here, except for message.orignalRegId
    },
    {
        method: 'adm',
        ... // Same structure here, except for message.orignalRegId
    },
]

GCM

NOTE: If you provide more than 1.000 registration tokens, they will automatically be splitted in 1.000 chunks (see this issue in gcm repo)

The following parameters are used to create a GCM message. See https://developers.google.com/cloud-messaging/http-server-ref#table5 for more info:

    // Set default custom data from data
    let custom;
    if (typeof data.custom === 'string') {
        custom = {
            message: data.custom,
        };
    } else if (typeof data.custom === 'object') {
        custom = Object.assign({}, data.custom);
    } else {
        custom = {
            data: data.custom,
        };
    }
 
    custom.title = custom.title || data.title || '';
    custom.message = custom.message || data.body || '';
    custom.sound = custom.sound || data.sound || undefined;
    custom.icon = custom.icon || data.icon || undefined;
    custom.msgcnt = custom.msgcnt || data.badge || undefined;
    if (opts.phonegap === true && data.contentAvailable) {
        custom['content-available'] = 1;
    }
 
    const message = new gcm.Message({ // See https://developers.google.com/cloud-messaging/http-server-ref#table5
        collapseKey: data.collapseKey,
        priority: data.priority === 'normal' ? data.priority : 'high',
        contentAvailable: data.contentAvailable || false,
        delayWhileIdle: data.delayWhileIdle || false, // Deprecated from Nov 15th 2016 (will be ignored)
        timeToLive: data.expiry - Math.floor(Date.now() / 1000) || data.timeToLive || 28 * 86400,
        restrictedPackageName: data.restrictedPackageName,
        dryRun: data.dryRun || false,
        data: data.custom,
        notification: {
            title: data.title, // Android, iOS (Watch)
            body: data.body, // Android, iOS
            icon: data.icon, // Android
            sound: data.sound, // Android, iOS
            badge: data.badge, // iOS
            tag: data.tag, // Android
            color: data.color, // Android
            click_action: data.clickAction || data.category, // Android, iOS
            body_loc_key: data.locKey, // Android, iOS
            body_loc_args: data.locArgs, // Android, iOS
            title_loc_key: data.titleLocKey, // Android, iOS
            title_loc_args: data.titleLocArgs, // Android, iOS
        },
    }

data is the parameter in push.send(registrationIds, data)

See node-gcm fields

Note: parameters are duplicated in data and in notification, so in fact they are being send as:

    data: {
        title: 'title',
        message: 'body',
        sound: 'mySound.aiff',
        icon: undefined,
        msgcnt: undefined
        // Any custom data
        sender: 'appfeel-test',
    },
    notification: {
        title: 'title',
        body: 'body',
        icon: undefined,
        sound: 'mySound.aiff',
        badge: undefined,
        tag: undefined,
        color: undefined,
        click_action: undefined,
        body_loc_key: undefined,
        body_loc_args: undefined,
        title_loc_key: undefined,
        title_loc_args: undefined
    }

In that way, they can be accessed in android in the following two ways:

    String title = extras.getString("title");
    title = title != null ? title : extras.getString("gcm.notification.title");

PhoneGap compatibility mode

In case your app is written with Cordova / Ionic and you are using the PhoneGap PushPlugin, you can use the phonegap setting in order to adapt to the recommended behaviour described in https://github.com/phonegap/phonegap-plugin-push/blob/master/docs/PAYLOAD.md#android-behaviour.

    const settings = {
        gcm: {
            id: '<yourId>',
            phonegap: true
        }
    }

APN

The following parameters are used to create an APN message:

{
    retryLimit: data.retries || -1,
    expiry: data.expiry || ((data.timeToLive || 28 * 86400) + Math.floor(Date.now() / 1000)),
    priority: data.priority === 'normal' ? 5 : 10,
    encoding: data.encoding,
    payload: data.custom || {},
    badge: data.badge,
    sound: data.sound || 'ping.aiff',
    alert: data.alert || {
        title: data.title,
        body: data.body,
        'title-loc-key': data.titleLocKey,
        'title-loc-args': data.titleLocArgs,
        'loc-key': data.locKey,
        'loc-args': data.locArgs,
        'launch-image': data.launchImage,
        action: data.action,
    },
    topic: data.topic, // Required
    category: data.category || data.clickAction,
    contentAvailable: data.contentAvailable,
    mdm: data.mdm,
    urlArgs: data.urlArgs,
    truncateAtWordEnd: data.truncateAtWordEnd,
    collapseId: data.collapseKey,
    mutableContent: data.mutableContent || 0,
}

data is the parameter in push.send(registrationIds, data)

See node-apn fields
Please note that topic is required (see node-apn docs)

ADM

The following parameters are used to create an ADM message:

const data = Object.assign({}, _data); // _data is the data passed as method parameter
const consolidationKey = data.consolidationKey;
const expiry = data.expiry;
const timeToLive = data.timeToLive;
 
delete data.consolidationKey;
delete data.expiry;
delete data.timeToLive;
 
const ADMmesssage = {
    expiresAfter: expiry - Math.floor(Date.now() / 1000) || timeToLive || 28 * 86400,
    consolidationKey,
    data,
};

data is the parameter in push.send(registrationIds, data)

See node-adm fields
