Global JS Objects

DronaHQ provides a powerful extension of JS Objects. JS Objects provides users flexibility with writing functions, key-value pairs, stating variables, and more, which later can be accessed in the app easily and recurrently with the use of keywords. The most important part of JS Object Extension is that, once you save an object, it can be accessible from any app in the DronaHQ account, so we can say that it is globally provided.

We will know more about writing and using Global JS Objects in this article. You can export your JS functions and variables defined in Global JS Objects section that you can call globally in any app at any place.

Creating Global JS Objects

Login to your DronaHQ account Go-to, Profile -> Extensions -> JS Object Editor.

Simple Database GUI
Global JS Objects config screen.

You will notice that a structure is maintained already in the JS Object with dummy data. Once JS Object defining is done, click on Save.

Global JS object Structure

The JS Object of the DronaHQ follows this format, where user can write their own code, mention variables, write functions, and more, provided that their keywords should be made accessible under the ExportModule :

// Internal Variable  
var myInternalVariable = "This is an Internal Variable";
// Variable Can be accessible outside
var myExternalVariable = "This global is an External Variable";
// Internal Function
function myInternalFun() {
// Code Goes here
// Function Can be accessible outside
function myExternalFun (data) {
// Code Goes here
return data;
function abc (data) {
// Code Goes here
return data;
var num1= 10;

function multi (){
return num1*5;
ExportModule = {
myExternalFun: myExternalFun,
myExternalVariable: myExternalVariable,


The JS Objects defined here are available across Apps in Data Binding, Event Actions, JS Transform, and Any other place that supports JavaScript. Make sure your custom code won’t create any security vulnerabilities, Unsecured code could expose sensitive customer information.


Functions or Variables you add in that Export Module only that functions will be accessible outside or in other ways only exported functions/variables will be accessible in App.

If you do not export the functions and variables with the export module, the JS object will be invalid and can’t be defined as DronaHQ does not recognize them and throws an error.


There is a dropdown provided just before the script where you can find all the exported keywords of functions and variables, which all are available to be used in the app.

Select one keyword from the dropdown, and the script will run for it particularly. Test your JS functions by selecting from the above dropdown and passing test data to view its result output. Use the below syntax in your app to call this function.

There is a specific syntax to call the global JS objects -



Once you click on Run Script, the end result output will be showcased in Output area.

Using JS Object

JavaScript Code:

function calculateInsurancePremium(age, gender, coverageAmount, tobaccoUsage) {
// Base premium rates per $1,000 of coverage
const basePremiumRates = {
male: 15,
female: 12,

// Factors for coverage amount and tobacco usage
const coverageAmountFactor = 0.1; // 10% increase
const tobaccoUsageSurcharge = 0.5; // 50% surcharge

// Determine base premium rate based on age and gender
const basePremiumRate = basePremiumRates[gender.toLowerCase()];
const basePremium = basePremiumRate * (coverageAmount / 1000);

// Adjust base premium based on coverage amount
const coverageAmountAdjustment = basePremium * coverageAmountFactor;
const adjustedBasePremium = basePremium + coverageAmountAdjustment;

// Apply tobacco usage surcharge if applicable
let finalPremium = adjustedBasePremium;
if (tobaccoUsage.toLowerCase() === ‘smoker’) {
const tobaccoSurcharge = adjustedBasePremium * tobaccoUsageSurcharge;
finalPremium += tobaccoSurcharge;

// Return the final premium amount
return finalPremium;

// Example usage
const age = 40;
const gender = ‘Male’;
const coverageAmount = 500000;
const tobaccoUsage = ‘Smoker’;

const premium = calculateInsurancePremium(age, gender, coverageAmount, tobaccoUsage);
console.log(‘Final Premium Amount:, premium);

ExportModule = {
calculateInsurancePremium: calculateInsurancePremium


JSOBJECTS_GLOBAL.calculateInsurancePremium(25, 'Female', 5000000, 'non-smoker');



we can now Save it. using Save button.

Using function inside app

Now, we can use the JS object from any app, with help of the keyword:
