Usage

$3

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 fcm or apn respectively.

`js
import PushNotifications from 'node-pushnotifications';

const settings = {
fcm: {
appName: 'localFcmAppName',
serviceAccountKey: require('../firebase-project-service-account-key.json'), // firebase service-account-file.json,
credential: null, // 'firebase-admin' Credential interface
// Optional Firebase Admin SDK AppOptions
projectId: 'your-project-id', // Explicitly set the Google Cloud project ID
databaseURL: 'https://your-database.firebaseio.com', // Realtime Database URL (optional)
storageBucket: 'your-bucket.appspot.com', // Cloud Storage bucket (optional)
serviceAccountId: 'your-email@your-project.iam.gserviceaccount.com', // Service account email (optional)
httpAgent: undefined, // HTTP Agent for proxy support (optional)
httpsAgent: undefined, // HTTPS Agent for proxy support (optional)
},
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 >',
},
TTL: 2419200,
contentEncoding: 'aes128gcm',
headers: {}
},
isAlwaysUseFCM: false, // true all messages will be sent through FCM API

};
const push = new PushNotifications(settings);
`

- FCM options: see firebase-admin (read FCM section below!) - used for Android and fallback for other platforms
- APN options: see node-apn
- ADM options: see node-adm
- WNS options: see wns
- Web-push options: see web-push

* isAlwaysUseFCM: when set to true, will send all notifications through FCM instead of platform-specific services

_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.

$3

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.

`js
// 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:

#### Object regId

It can be of 2 types:

- Mobile regId:

`json
{
"id": "INSERT_YOUR_DEVICE_ID",
"type": "apn"
}
`

Where type can be one of: 'apn', 'fcm', 'adm', 'wns', 'webPush'. The types are available as constants:

`js
import { WEB, WNS, ADM, FCM, 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

`json
{
"endpoint": "< Push Subscription URL >",
"keys": {
"p256dh": "< User Public Encryption Key >",
"auth": "< User Auth Secret >"
}
}
`

#### String regId (not recommended)

It is not recommended, as the reg id is of variable length, which makes it difficult to identify if it is an APN regId or FCM 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: 'fcm'
- otherwise: 'unknown' (the notification will not be sent)

Android:

- All Android notifications are sent through Firebase Cloud Messaging (FCM)
- If you provide more than 1.000 registration tokens, they will automatically be split into 1.000 chunks
- You are able to send to custom topics or conditions through FCM (see firebase-admin docs)

Example:

`javascript
const data = { ...data, recipients };
`

$3

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

`js
const data = {
title: 'New push notification', // REQUIRED for Android
topic: 'topic', // REQUIRED for iOS (apn and fcm)
/* 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

}
});

// Or you could use it as a promise:

.then((results) => { ... })
.catch((err) => { ... });
`

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

`js

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
- rawPayload (hidden 'node-apn' lib notification param) source code this param will replace all payload

$3

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.

`js
const silentPushData = {
topic: 'yourTopic',
contentAvailable: true,
silent: true,
custom: {
yourKey: 'yourValue',
...
}
}
`

FCM

All Android push notifications are sent through Firebase Cloud Messaging (FCM) using the firebase-admin library.

Firebase Admin SDK App Options:

The following Firebase Admin SDK AppOptions are supported and can be passed in settings.fcm:

- appName - Firebase app name (required)
- serviceAccountKey - Firebase service account file use downloaded 'service-account-file.json'
- credential - Firebase credential (one of serviceAccountKey or credential is required)
- projectId - Explicitly set the Google Cloud project ID (optional)
- databaseURL - Realtime Database URL (optional)
- storageBucket - Cloud Storage bucket name (optional)
- serviceAccountId - Service account email (optional)
- databaseAuthVariableOverride - Auth variable override for Realtime Database (optional)
- httpAgent - HTTP Agent for proxy support (optional, see Proxy section)
- httpsAgent - HTTPS Agent for proxy support (optional, see Proxy section)

`js
const tokens = ['e..Gwso:APA91.......7r910HljzGUVS_f...kbyIFk2sK6......D2s6XZWn2E21x'];

const notifications = {
collapseKey: Math.random().toString().replace('0.', ''),
priority: 'high',
sound: 'default',
title: 'Title 1',
body: 'Body 2',
// titleLocKey: 'GREETING',
// titleLocArgs: ['Smith', 'M'],
// fcm_notification: {
// title: 'Title 1',
// body: 'Body 2',
// sound: 'default',
// default_vibrate_timings: true,
// },
// alert: {
// title: 'Title 2',
// body: 'Body 2'
// },
custom: {
friend_id: 54657,
list_id: 'N7jSif1INyZkA7r910HljzGUVS',
},
};

pushNotifications.send(tokens, notifications, (error, result) => {
if (error) {
console.log('[error]', error);
throw error;
} else {
console.log('[result]', result, result.at(0));
}
});
`

fcm_notification - object that will be passed to FCM message notification field

Fcm object that will be sent to provider (Fcm message format) :

`json
{
"data": {
"friend_id": "54657",
"list_id": "N7jSif1INyZkA7r910HljzGUVS"
},
"android": {
"collapse_key": "5658586678087056",
"priority": "high",
"notification": {
"title": "Title 1",
"body": "Body 2",
"sound": "default"
},
"ttl": 2419200000
},
"apns": {
"headers": {
"apns-expiration": "1697456586",
"apns-collapse-id": "5658586678087056"
},
"payload": {
"aps": {
"sound": "default",
"alert": {
"title": "Title 1",
"body": "Body 2"
}
}
}
},
"tokens": ["e..Gwso:APA91.......7r910HljzGUVS_f...kbyIFk2sK6......D2s6XZWn2E21x"]
}
`

WNS

The following fields are used to create a WNS message:

`js
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;

wnsnotificationMethod => { ... });

`

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

- See wns fileds

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.

ADM

The following parameters are used to create an ADM message:

`js
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

Web-Push

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.

`js
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

Proxy

The module supports proxy configuration at two different levels:

$3

To route Firebase Admin SDK network requests through a corporate proxy, configure HTTP/HTTPS agents:

`javascript
import { HttpProxyAgent } from 'http-proxy-agent';
import { HttpsProxyAgent } from 'https-proxy-agent';

const settings = {
fcm: {
appName: 'myApp',
credential: { ... },
// Route all Firebase Admin SDK network traffic through proxy
httpAgent: new HttpProxyAgent(http://${env.proxy.host}:${env.proxy.port}),
httpsAgent: new HttpsProxyAgent(http://${env.proxy.host}:${env.proxy.port}),
},
};
`

This affects how the SDK communicates with Google's servers and applies to all Firebase services.

$3

To control how Android devices handle notifications in proxy scenarios, use the proxy property in the notification data:

`javascript
const data = {
title: 'Notification',
body: 'Test',
proxy: 'allow', // Can be 'allow', 'deny', or 'if_priority_lowered'
};

push.send(registrationIds, data);
`

This is a notification-level setting that tells the Android system whether to deliver the notification when the device is on a proxy network.

$3

For APN (Apple Push Notification), configure the proxy at the app settings level:

`javascript
const settings = {
apn: {
token: { ... },
proxy: {
host: ,
port:
}
}
};
`
