here is my index.js

```
'use-strict'

const admin = require('firebase-admin');
const functions = require('firebase-functions');
admin.initializeApp(functions.config().firebase);

exports.sendMessageNotification = functions.database.ref('DR/MELTING/{itemname}').onWrite(event => {
//const itemname = event.params.itemname;

console.log("Notificatiion Triggered Successfuly");
});

```
