Run long java-script by windev

HI I want to upload document to direbase server. Presently I am using this javascript with web GUI to upload pdf files over firebase server but I want to make it through windev. Can anyone suggest clue to perform it by windev:

The firebase API & domain ID has been changed to keep confidentiality

import firebase from 'firebase / app';
import 'firebase / storage';
var firebaseConfig = {
apiKey: "AIzqSyB_9w84qwee4Peim0n1MQJy3tw_nXF5OqE",
authDomain: "hvpfileserver.firebaseapp.com",
databaseURL: "

measurementId: "G-BQVWZVVE"
};

firebase.initializeApp (firebaseConfig);


const Storage = firebase.storage ();

export {
Storage, firebase as default
}
import {Storage} from "../firebase/index";
const uploadTask = Storage.ref (`documents / $ {rno} .pdf`);
uploadTask.put (this.state.fileObject) .on (
"state_changed",
(snapshot) => {
// Observe state change events such as progress, pause, and resume
},
(error) => {
// Handle unsuccessful uploads
console.log (error);
});
