a Node.JS wrapper library-port for Google Cloud Messaging for Android
node-gcm is a Node.JS library for Google Cloud Messaging for Android, which replaces Cloud 2 Device Messaging (C2DM).
$ npm install node-gcm
An Android device running 2.2 or newer and an API key as per GCM getting started guide.
According to below Usage reference, we could create such application:
var gcm = require'node-gcm';var message = ;messageaddData'key1' 'msg1';var regIds = 'YOUR_REG_ID_HERE';// Set up the sender with you API keyvar sender = 'YOUR_API_KEY_HERE';//Now the sender can be used to send messagessendersendmessage regIdsiferr console.errorerr;else console.logresult;;sendersendNoRetrymessage regIdsiferr console.errorerr;else console.logresult;;
var gcm = require'node-gcm';// Create a message// ... with default valuesvar message = ;// ... or some given valuesvar message =collapseKey: 'demo'delayWhileIdle: truetimeToLive: 3data:key1: 'message1'key2: 'message2';// Change the message data// ... as key-valuemessageaddData'key1''message1';messageaddData'key2''message2';// ... or as a data object (overwrites previous data object)messageaddDatakey1: 'message1'key2: 'message2';// Change the message variablesmessagecollapseKey = 'demo';messagedelayWhileIdle = true;messagetimeToLive = 3;messagedryRun = true;// Set up the sender with you API keyvar sender = 'insert Google Server API Key here';// Add the registration IDs of the devices you want to send tovar registrationIds = ;registrationIdspush'regId1';registrationIdspush'regId2';// Send the message// ... trying only oncesendersendNoRetrymessage registrationIdsiferr console.errorerr;else console.logresult;;// ... or retryingsendersendmessage registrationIdsiferr console.errorerr;else console.logresult;;// ... or retrying a specific number of times (10)sendersendmessage registrationIds 10iferr console.errorerr;else console.logresult;;
Notice that you can at most send notifications to 1000 registration ids at a time. This is due to a restriction on the side of the GCM API.
var message = ;// Add notification payload as key valuemessageaddNotification'title' 'Alert!!!';messageaddNotification'body' 'Abnormal data access';messageaddNotification'icon' 'ic_launcher';// as objectmessageaddNotificationtitle: 'Alert!!!'body: 'Abnormal data access'icon: 'ic_launcher';

To enable debug mode (print requests and responses to and from GCM),
DEBUG environment flag when running your app (assuming you use
node app.js to run your app):
DEBUG=node-gcm node app.js
