Google Firebase functions to iot device send config - node.js

Question

I am trying to use firebase functions to send config to an Iot device.Here is the tutorial which i am trying to use.This is the Node js code which i am deploying
The tutorial says after, after deployment whatever change i will do to my firebase database it will get sent to the iot device as device config.
registryid is INTERNET_OF_BULBS.
Iot device name is Iot-device-1.
The actual code in the tutorial doesnt work for deployment.So I removed the import modules part and used require.
The tutorial does these imports.
import * as admin from "firebase-admin";
import * as functions from 'firebase-functions';
import { runInDebugContext } from 'vm';
import { DeviceManager } from './devices';
how do i import { DeviceManager } from './devices';
so i am doing only 2 imports.Otherwise ,if i use import in my index.js it gives error when deploying.
1:1 error Parsing error: 'import' and 'export' may appear only with 'sourceType: module'
Below is my index.js file.
const admin =require('firebase-admin');
const functions =require('firebase-functions');
admin.initializeApp();
// create a device manager instance with a registry id, optionally pass a region
const dm = new DeviceManager('INTERNET_OF_BULBS');
const firestore = admin.firestore();
// start cloud function
exports.configUpdate = functions.firestore
// assumes a document whose ID is the same as the deviceid
.document('device-configs/Iot-device-1')
.onWrite((change,context) => {
var beforeData = change.before.val(); // data before the write
var afterData = change.after.val();
if (context) {
await dm.setAuth();
console.log(context.params.deviceId);
// get the new config data
const configData = change.after.data();
return dm.updateConfig(context.params.deviceId, configData);
} else {
throw(Error("no context from trigger"));
}
})
Here is the error on my shell when i am trying to deploy,the above code.
