How to Build Engaging Chatbots in React JS for Enhanced Customer Engagement

Updated on February 12, 2025

In the hyper competitive environment of 2024, Customer retention is the new Customer Acquisition. As traditional ways of keeping customers happy fail to impress, innovative solutions such as chatbots are stepping up to claim the mantle.

One of the most popular ways to build these chatbots is using React.JS. As an enterprise, training your team on React.JS to build chatbots can be one of the most critical decisions you take. And with good reason.

React.JS is one of the best ways to build engaging and interactive chatbots, because:

1. Component based architecture: Enables to use modular and reusable code.
2. Declarative syntax: This makes creation of interactive UI simple, which plays a crucial role in creating engaging user experiences.
3. Virtual DOM: Enhances performance by minimizing unnecessary DOM operations, meaning smooth and responsive chatbot interactions.
4. Robust community support and extensive documentation.

In this blog post, we will teach you how to make your React.js website stand out by adding a chatbot. Ready to give your project a conversational upgrade?

We’ll break down the process step by step and make it accessible for everyone.

Prerequisites

Before we dive into building a chatbot, make sure you have the following prerequisites in place: 

1. Basic knowledge of JavaScript and React JS. 
2. Node.js and npm (Node Package Manager) are installed on your development machine. 
3. A code editor of your choice (e.g., Visual Studio Code). 
4. A working React Native project set up.

Steps to Build Chatbot in React JS

We’ll break down the process of building a chatbot for your React JS website step by step and make it accessible for everyone. We’ll do the integration in 2 phases:

1. Create a Kompose chatbot and set up the answers.
2. Add the created chatbot to your React JS website.

Let’s jump right into it.

Phase 1: Create a chatbot in Kompose and setup the answers

Step 1: Setup an account in Kommunicate

If you do not have an account in Kommunicate, you can create one here for free.

Next, log in to your Kommunicate dashboard and navigate to the Bot Integration section. Locate the Kompose section and click on Integrate Bot.

If you want to build a bot from scratch, select a blank template and go to the Set up your bot section. Select the name of your Bot, your bot’s Avatar, and your bot’s default language, and click “Save and Proceed”.

You are now done creating your bot and all you have to worry about now is to “Enable bot to human transfer” when the bot encounters a query it does not understand. Enable this feature and click “Finish Bot Setup.”

Newly created bot here: Dashboard →Bot Integration → Manage Bots.

Step 2: Create welcome messages & answers for your chatbot

Go to the ‘Kompose – Bot Builder’ section and select the bot you created.

First, set the welcome message for your chatbot. The welcome message is the first message that the chatbot sends to the user who initiates a chat.

Click the “Welcome Message” section. In the “Enter Welcome message – Bot’s Message” box, provide the message your chatbot should be shown to the users when they open the chat and then save the welcome intent.

After creating the welcome message, the next step is to feed answers/intents. These answers/intents can be the common questions about your product and service.

The answers section is where you’ve to add all the user’s messages and the chatbot responses.

Go to the “Answer” section, click +Add, then give an ‘Intent name’

In the Configure user’s message section – you need to mention the phrases that you expect from the users that will trigger. 

Configure the bot’s reply section – you need to mention the responses (Text or as Rich messages) the chatbot will deliver to the users for the particular message. You can add any number of answers and follow-up responses for the chatbot. Here, I have used a custom payload by selecting the “Custom” option in the “More” option.

Once you have configured the responses, you need to click on “Train Bot” which is at the button right and to the left of the preview screen. Once successfully trained, a toast “Anser training completed” will come at the top right corner.

Phase 2: Add the created React JS chatbot to the website

Step 4: Create a React app

Create a new React app (my-app) by using the command in your terminal or Command Prompt:

npx create-react-app my-app

Step 5: Now, navigate to the my-app folder

cd my-app

Step 6: Create a new file chat.js inside the src folder and install Komminicate Chatbot

Once you create the chat.js, add the below code in componentDidMount. The below code will launch a chat widget on your website with the integrated Dialogflow bot. Make sure to replace <YOUR_APP_ID> with your Kommunicate application ID.

You can get this code in the install section of Kommunicate as well.

import React, { Component } from “react”;
class KommunicateChat extends Component {
constructor(props){
super(props);
}
componentDidMount(){
(function(d, m){
var kommunicateSettings = {“appId”:”2bf085baaad3f559103cf127c1cc98c10″,”popupWidget”:true,”automaticChatOpenOnNavigation”:true};
var s = document.createElement(“script”); s.type =“text/javascript”; s.async = true;
s.src = “https://widget.kommunicate.io/v2/kommunicate.app“;
var h = document.getElementsByTagName(“head”)[0]; h.appendChild(s);

window.kommunicate = m; m._globals = kommunicateSettings;
})(document, window.kommunicate || {});
}
render(){
return(
<div>
<h1>Hello</h1>
</div>
)
}
}
export default KommunicateChat;

Step 7: Start your app locally

Use the following command to start your newly created website with the installed Kompose bot.
npm start

Voila! How simple was that? In these few simple steps, you could integrate the Kompose bot into React JS websites. This is how the chat widget looks on a website:
