AWS SNS push notification using Node JS

Got the answer.

var AWS = require('aws-sdk');

AWS.config.update({
  accessKeyId: '{AWS_KEY}',
  secretAccessKey: '{AWS_SECRET}',
  region: '{SNS_REGION}'
});

var sns = new AWS.SNS();

  var payload = {
    default: 'Hello World',
    APNS: {
      aps: {
        alert: 'Hello World',
        sound: 'default',
        badge: 1
      }
    }
  };

  // first have to stringify the inner APNS object...
  payload.APNS = JSON.stringify(payload.APNS);
  // then have to stringify the entire message payload
  payload = JSON.stringify(payload);

  console.log('sending push');
  sns.publish({
    Message: payload,      // Required
    MessageStructure: 'json',
    TargetArn: {{TargetArn}} // Required
  }, function(err, data) {
    if (err) {
      console.log(err.stack);
      return;
    }

    console.log('push sent');
    console.log(data);
  });
});

Use sns-mobile

The below example creates an SNS instance for an Android application identified by a PlatformApplicationArn

var SNS = require('sns-mobile'),


 EVENTS = SNS.EVENTS;

var SNS_KEY_ID = process.env['SNS_KEY_ID'],
  SNS_ACCESS_KEY = process.env['SNS_ACCESS_KEY'],
  ANDROID_ARN = process.env['SNS_ANDROID_ARN'];

var androidApp = new SNS({
  platform: SNS.SUPPORTED_PLATFORMS.ANDROID,
  region: 'eu-west-1',
  apiVersion: '2010-03-31',
  accessKeyId: SNS_ACCESS_KEY,
  secretAccessKey: SNS_KEY_ID,
  platformApplicationArn: ANDROID_ARN,
  //sandbox: true (This is required for targetting (iOS) APNS_SANDBOX only) 
});

// Add a user, the endpointArn is their unique id 
// endpointArn is required to send messages to the device 
androidApp.addUser('some_fake_deviceid_that_i_made_up', JSON.stringify({
  some: 'extra data'
}), function(err, endpointArn) {
  if(err) {
    throw err;
  }

  // Send a simple String or data to the client 
  androidApp.sendMessage(enpointArn, 'Hi There!', function(err, messageId) {
    if(err) {
      throw err;
    }

    console.log('Message sent, ID was: ' + messageId);
  });
});
