A node.js module for interfacing with Apple Push Notification, Google Cloud Messaging, Windows Push Notification, Web-Push Notification and Amazon Device Messaging services.
npm install node-pushnotifications --saveNode version >= 14.x.x
- Powerful and intuitive.
- Multi platform push notifications.
- Automatically detects destination device type.
- Unified error handling.
- Written in ES6, compatible with ES5 through babel transpilation.
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.
import PushNotifications from 'node-pushnotifications';
const settings = {
gcm: {
id: 'your-GCM-id',
phonegap: false, // phonegap compatibility mode, see below (defaults to false)
...
},
apn: {
token: {
key: './certs/key.p8', // optionally: fs.readFileSync('./certs/key.p8')
keyId: 'ABCD',
teamId: 'EFGH',
},
production: false // true for APN production environment, false for APN sandbox environment,
...
},
adm: {
client_id: null,
client_secret: null,
...
},
wns: {
client_id: null,
client_secret: null,
notificationMethod: 'sendTileSquareBlock',
...
},
web: {
vapidDetails: {
subject: '< \'mailto\' Address or URL >',
publicKey: '< URL Safe Base64 Encoded Public Key >',
privateKey: '< URL Safe Base64 Encoded Private Key >',
},
gcmAPIKey: 'gcmkey',
TTL: 2419200,
contentEncoding: 'aes128gcm',
headers: {}
},
isAlwaysUseFCM: false, // true all messages will be sent through node-gcm (which actually uses FCM)
};
const push = new PushNotifications(settings);- GCM options: see node-gcm
- APN options: see node-apn
- ADM options: see node-adm
- WNS options: see wns
- Web-push options: see web-push
isAlwaysUseFCM: use node-gcm to send notifications to GCM (by default), iOS, ADM and WNS.
iOS: It is recommended 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.
Registration id's should be defined as objects (or strings which is not recommended and should be used at your own risk, it is kept for backwards compatibility).
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');The PN.send() method later detects device type and therefore used push method, based on the id stucture. Check out the method PN.getPushMethodByRegId how this detection works.
Actually there are several different supported reg id's:
It can be of 2 types:
- Mobile regId:
{
"id": "INSERT_YOUR_DEVICE_ID",
"type": "apn"
}Where type can be one of: 'apn', 'gcm', 'adm', 'wns', 'webPush'. The types are available as constants:
import { WEB, WNS, ADM, GCM, APN } from 'node-pushnotifications';
const regId = {
id: 'INSERT_YOUR_DEVICE_ID',
type: APN,
};In case of webPush, id needs to be as defined below for Web subscription.
- Web subscription see web-push
{
"endpoint": "< Push Subscription URL >",
"keys": {
"p256dh": "< User Public Encryption Key >",
"auth": "< User Auth Secret >"
}
}It is not recommended, as Apple stays that the reg id is of variable length, which makes difficult to identify if it is a APN regId or GCM regId.
regId.substring(0, 4) === 'http': 'wns'/^(amzn[0-9]*.adm)/i.test(regId): 'adm'(regId.length === 64 || regId.length === 160) && /^[a-fA-F0-9]+$/.test(regId): 'apn'regId.length > 64: 'gcm'- otherwise: 'unknown' (the notification will not be sent)
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)
- You are able to send to device groups or other custom recipients instead of using a list of device tokens (see node-gcm docs). Documentation can be found in the GCM section..
Example:
const data = { ...data, recipients };Create a JSON object with a title and message and send the notification.
const data = {
title: 'New push notification', // REQUIRED for Android
topic: 'topic', // REQUIRED for iOS (apn and gcm)
/* The topic of the notification. When using token-based authentication, specify the bundle ID of the app.
* When using certificate-based authentication, the topic is usually your app's bundle ID.
* More details can be found under https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/sending_notification_requests_to_apns

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;
custom.icon = custom.icon || data.icon;
custom.msgcnt = custom.msgcnt || data.badge;
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
image: data.image, // Android
style: data.style, // Android
picture: data.picture, // 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
android_channel_id: data.android_channel_id, // Android
},
}data is the parameter in push.send(registrationIds, data)
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,
image: undefined,
style: undefined,
picture: 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,
android_channel_id: 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");GCM supports silent push notifications which are not displayed to the user but only used to transmit data.
const silentPushData = {
topic: 'yourTopic',
silent: true,
custom: {
yourKey: 'yourValue',
...
}
}Internally, silent: true will tell node-gcm not to send the notification property and only send the custom property. If you don't specify silent: true then the push notifications will still be visible on the device. Note that this is nearly the same behavior as phoneGap: true and will set content-available to true.
In order to override the default behaviour of sending the notifications to a list of device tokens,
you can pass a recipients field with your desired recipients. Supported fields are to and condition as documented in the node-gcm docs.
Example:
const dataWithRecipientTo = { ...yourData, recipients: { to: 'topicName' } };
const dataWithRecipientCondition = { ...yourData, recipients: { condition: 'topicName' } };
push.send(registrationIds, dataWithRecipientTo)
.then((results) => { ... })
.catch((err) => { ... });Be aware that the presence of a valid data.recipient field will take precendence over any Android device tokens passed with the registrationIds.
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,
},
};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.silent === true ? undefined : data.badge,
badge: data.sound === true ? undefined : data.sound,
alert: data.sound === true ? undefined : 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,
threadId: data.threadId,
pushType: data.pushType
}data is the parameter in push.send(registrationIds, data)
- See node-apn fields
- Please note that
topicis required (see node-apn docs). When using token-based authentication, specify the bundle ID of the app. When using certificate-based authentication, the topic is usually your app's bundle ID. More details can be found under https://developer.apple.com/documentation/usernotifications/setting_up_a_remote_notification_server/sending_notification_requests_to_apns
iOS supports silent push notifications which are not displayed to the user but only used to transmit data.
Silent push notifications must not include sound, badge or alert and have normal priority.
By setting the silent property to true the values for sound, badge and alert will be overridden to undefined.
Priority will be overridden to normal.
const silentPushData = {
topic: 'yourTopic',
contentAvailable: true,
silent: true,
custom: {
yourKey: 'yourValue',
...
}
}The following fields are used to create a WNS message:
const notificationMethod = settings.wns.notificationMethod;
const opts = Object.assign({}, settings.wns);
opts.headers = data.headers || opts.headers;
opts.launch = data.launch || opts.launch;
opts.duration = data.duration || opts.duration;
delete opts.notificationMethod;
delete data.headers;
delete data.launch;
delete data.duration;
wns[notificationMethod](regId, data, opts, (err, response) => { ... });data is the parameter in push.send(registrationIds, data)
Note: Please keep in mind that if data.accessToken is supplied, each push notification will be sent after the previous one has been responded. This is because Microsoft may send a new accessToken in the response and it should be used in successive requests. This can slow down the whole process depending on the number of devices to send.
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)
Data can be passed as a simple string payload. If you do not pass a string, the parameter value will be stringified beforehand.
Settings are directly forwarded to webPush.sendNotification.
const payload = typeof data === 'string' ? data : JSON.stringify(data);
webPush.sendNotification(regId, payload, settings.web);A working server example implementation can be found at https://github.com/alex-friedl/webpush-example/blob/master/server/index.js
