Freshworks developer platform now supports React local development natively in the FDK through Webpack 5. This tutorial is intended to walk you through the implementation and assist you in building your first react app using FDK.


The FDK comes built-in with Webpack 5 and a Webpack configuration file to mount during the compilation and the build phases, whenever the FDK detects the project is developed with React, the project is compiled using the Webpack with default Webpack configuration.

Positive : Though the FDK has a default Webpack configuration for React apps, It is possible to provide custom configurations, you can follow this tutorial to create your custom webpack config.


What we'll build today?

In this tutorial we will extend the your_first_react_app template and build a react app that uses the data method fetch ticket details and display information through showNotify method.

To create a new React project,

vel@freshworks:~$ mkdir my_app && cd my_app

Choose Product

Choose Product

vel@freshworks:~/my_app$ npm install
vel@freshworks:~/my_app$ fdk run

local react

local react

From the above Screenshot, we can see that the react app is running successfully.

The React App in the Freshworks ecosystem is similar to the React app created using create-react-app or a React app bundled using the Webpack, with some minor changes in the folder structure to support integration with the FDK.

The folder structure of the React app is explained below

Choose Product

The manifest.json file

The manifest.json file contains the app metadata about your app, such as app locations, platform version, and other app related information

The package.json file

The package.json file contains the information about the framework used in the app, the dependencies, and devDependencies used by the app, and configurations if any.

The app folder

The app folder contains the built/compiled assets of the app. The content of the app folder is served by the FDK in http://localhost:10001/iframe during fdk run

Negative : * Do not delete, replace or modify the index.html file inside the app folder, any changes made will be overwritten during the build. If you need to add or remove anything in the app/index.html, make sure you do it in public/index.html as it serves as the template file for app/index.html

The Config folder

The config folder contains the installation parameter of the app.

Negative : Do not define your custom webpack config inside the config folder

The src folder

The src folder contains your react components and services.

The public folder

The public folder contains an index.html file which serves as a template to the app/index.html. Adding CSS or scripts to the app can be done in the public/index.html.

The jest.config.js file

The jest.config.js contains the configurations related to jest unit tests. Alternatively, this can be directly defined in the package.json like shown below.


  "scripts": {
    "test": "jest test --coverage"
  "jest": {
    "roots": [

The setUpTests.js file

The setupTests.js is needed when your app uses a browser API that you need to mock in your tests or if you need a global setup before running your tests, It will be automatically executed before running your tests.

To know more about setupTests.js, please visit this link

The __mocks__ folder

The __mocks__ folder contains all the manual mocks required by jest as per jest's naming convention.

Please visit this link to know more about __mocks__

Now that we have the template up and running for the React app without any errors, let us start building an app that uses Data method and Interface method.

Let's edit the src/components/HelloUser.js to display a button, which on click displays a notification bar with Ticket ID and Agent Name.

Adding the button.

Add a button to component inside the return function

  return (
      <button>Show Details</button>

Create a new function to display the notification. The interface method can be accessed via the client object passed as a prop from the App.js component. The HelloUser.js component adding functions to display ticket details is shown below.

import React from 'react'
import PropTypes from 'prop-types'

const HelloUser = ({ client }) => {

  const showDetails = () => {"ticket").then(
      function (data) {
        showNotification(`The ticket ${} with the subject ${data.ticket.subject} is created by the contact ${data.ticket.requester_id}`);
      function (error) {
        console.log("error", error);

  const showNotification = (message) => {
    client.interface.trigger("showNotify", {
      type: "success",
      message: message

  return (
      <button onClick={showDetails}>Show Details</button>

HelloUser.propTypes = {
  client: PropTypes.object
export default HelloUser

Once the necessary changes are made to the HelloUser.js component, the app should work as shown in the GIF below.

Completed React App

Once the app is done, the app can be packed like anyother FDK app using fdk pack command

Since the integration is in the early stages, there are few cavets that you need to keep in mind

In this Tutorial we learned about,

✅ Creating a react app using FDK ✅ Using the platform features in the react app.

What's next?

Now that you are familiar with creating a basic react app using FDK, you can start adding more complex react features like router, context API, and state management.
