We’ll explore how to build AI-powered apps with ReactJS, looking at key concepts, useful libraries, and real-world examples. By the end, you’ll have a solid understanding of how to start incorporating AI into your React projects to create smarter, more futuristic solutions.

Why React and AI Make a Great Pair

Why React and AI Make a Great Pair

React and AI work extremely well together for several reasons:

React’s Declarative Nature

React uses a declarative paradigm where you simply declare what each UI component should look like for any given state. This aligns nicely with AI where you define the intents, entities, and flows for an intelligent agent and let the machine learning models handle the complex logic behind the scenes.

React’s Component Architecture

React’s component-based architecture compliments AI development. Complex AI capabilities like speech recognition or image processing can be wrapped in reusable React components with well-defined interfaces.

React’s Fast Rendering

React uses a virtual DOM to minimize DOM operations and enable lightning-fast UI updates. This high performance suits AI applications which often require time-sensitive, dynamic interfaces.

React’s Maturity and Popularity

React has a huge community behind it which has produced many production-ready libraries for tasks like state management and data fetching. This rich ecosystem benefits AI development.

React’s Flexibility

React is unopinionated and flexible. It can integrate with popular AI libraries like TensorFlow, Dialogflow, and LUIS, enabling you to leverage robust machine learning capabilities.

The combination of React’s intuitive programming model and AI’s intelligent automation can help developers build the next generation of smart web experiences. Let’s look at some real-world examples.

Powerful Examples of AI + ReactJS

Powerful Examples of AI + ReactJS

Chatbots and Conversational UI

Chatbots allow users to interact with websites and apps conversationally via text or voice. React lends itself well to building polished chatbot interfaces:

// Chatbot message component function ChatMessage(props) { return <div className=”chat-message”> {props.text} </div>; } // Display bot response <ChatMessage text={botResponse} />

The logic driving the chatbot, such as natural language processing, can be handled by external services like Dialogflow, Lex, or Azure Bot Service. React simply renders the interface.

Companies like Spectrum and Drift use React to build conversational UIs like chatbots and live chat platforms. The conversational components are reusable across web and mobile apps.

AI-Powered Recommendation Engines

Recommendation engines suggest relevant content to users based on interests, behavior, and more. React is commonly used to display these personalized recommendations:

// Recommendation component function Recommendation({title, image}) { return ( <div className=”recommendation”> <img src={image} /> <h3>{title}</h3> </div> ); } // Display recommendations <div className=”recommendations”> { => <Recommendation {…rec} /> )} </div>

The recommendations themselves can be generated by algorithms built on machine learning frameworks like TensorFlow or PyTorch. Overall, React + AI enables intelligent, personalized interfaces.

Netflix and Amazon use React to deliver tailored recommendations to hundreds of millions of users. The React components refresh seamlessly when recommendations change.

Intelligent Forms with React

Forms are used ubiquitously across the web. With AI, forms can be made smarter by detecting user intent, filling fields automatically, and improving conversion rates.

For example, forgetful users can be reminded to fill in a specific field, and address fields can be autosuggested based on user location to reduce typos. React form components like Formik integrate nicely with AI tools to power such experiences.

The startup Typeform uses React + AI to create conversational forms that feel like chatting with an assistant. This boosts completion rates. Their form components are reusable across channels.

Interactive Vision Applications

Computer vision AI enables applications to “see” by processing and analyzing visual content.combined with React, this opens up possibilities like:

  • Image classifiers to detect objects/scenes
  • Face detection and recognition in images/video
  • Background blurring in video calls
  • Interactive photo filters powered by neural networks
  • Image/video search using visual similarity
  • Analyzing emotions and demographics from faces

Computer vision services like Clarifai, Amazon Rekognition, and Microsoft Computer Vision run the deep learning models. React handles the dynamic visual interfaces.

Snapchat uses React for their real-time augmented reality filters based on face detection. The same React components render the fun filters across their web and mobile apps.

Natural Language Interfaces

NLP techniques like sentiment analysis, named entity recognition, and intent detection can enable React apps to understand text. Useful examples:

  • Search interfaces powered by semantic search and autocomplete
  • Sentiment analysis on reviews, support tickets, or social media
  • Query intent detection on FAQ/help pages to direct users
  • Chatbot and voice assistants to handle natural conversations
  • Auto-tagging or categorizing content based on text analysis
  • Summarization of long articles into concise highlights

NLP services like MonkeyLearn, Dialogflow, and AWS Comprehend provide the language processing models. React builds the text-enabled UIs.

Grammarly uses React to build their writing assistant product, which checks text for errors, tone, clarity, engagement, and more using AI.

As you can see, React is versatile enough to deliver all kinds of intuitive AI experiences. Let’s look at some helpful libraries.

Handy React Libraries for AI Development

While React handles the UI layer, we need external AI services or models to enable the intelligent functionality. Here are some useful React libraries for integrating AI:


TensorFlow.js lets you run pre-trained TensorFlow machine learning models directly in the browser with Javascript. This enables features like image classification, speech recognition, and pose detection powered by deep learning. The models can be trained in Python, exported to TensorFlow.js, and integrated into React apps.

// Classify image with TensorFlow.js model const recognizer = await tf.loadGraphModel(MODEL_URL); const prediction = recognizer.classify(imgTensor);

React Speech Recognition

This provides a React hook that wraps the Web Speech API for voice interfaces. You can transcribe spoken words to text for features like voice search and dictation. It integrates nicely with chatbot and voice assistant UIs.

// Speech recognition const { transcript } = useSpeechRecognition();

Azure Cognitive Services

Microsoft Azure provides a set of pre-built cognitive APIs like vision, speech, search, and language through Azure Cognitive Services. Their React SDKs make it easy to call these APIs from React apps.

// Analyze image with Computer Vision API const client = new ComputerVisionClient(credentials); const tags = await client.tagImage(imageUrl);

Dialogflow API

Google’s Dialogflow provides tools for building conversational interfaces like chatbots. Their React SDK provides components like <DialogflowAgent> for easily integrating an agent. All the NLP runs on Google Cloud.

// Chatbot with Dialogflow <DialogflowAgent clientAccessToken={YOUR_TOKEN} />

There are many more helpful libraries like React Voice Components, LUIS React SDK, and Clarifai React Wrapper. The abundant React ecosystem enables you to find quality libraries for most AI use cases.

Now let’s walk through a sample React + AI project.

Building an AI-Powered Image Classifier App

Building an AI-Powered Image Classifier App

To demonstrate React and AI in action, let’s walk through a project that builds an image classifier web app powered by machine learning.

The app will:

  • Allow uploading an image
  • Classify the image into objects/scenes using a TensorFlow.js model
  • Display the top classifications with confidence scores

Project Setup

We’ll use create-react-app to bootstrap the React project:

# Create app npx create-react-app image-classifier cd image-classifier

Then install TensorFlow.js and react-dropzone for drag-and-drop image uploads:

npm install @tensorflow/tfjs @tensorflow-models/mobilenet react-dropzone

Importing Model

Next, we import the pre-trained MobileNet image classification model from TensorFlow.js:

// Import model import * as mobilenet from ‘@tensorflow-models/mobilenet’; async function loadModel() { const model = await mobilenet.load(); // … use model later } loadModel();

This model can classify ~1000 different objects like people, animals, vehicles, electronics etc.

Image Upload

We need to let users upload an image to classify. We can use React Dropzone for drag-and-drop file uploads:

// Image drag-and-drop import React, {useCallback} from ‘react’ import {useDropzone} from ‘react-dropzone’ function ImageUploader(props) { const onDrop = useCallback(acceptedFiles => { // Upload code }, []) const {getRootProps, getInputProps} = useDropzone({onDrop}) return ( <div {…getRootProps()}> <input {…getInputProps()} /> <p>Drag image here</p> </div> ) }

We’ll handle uploading the image file and invoking the model backend.

Classifying Image

Once an image is uploaded, we can classify it like so:

// Classify image const img = document.getElementById(‘image’); const predictions = await model.classify(img); // predictions contains classification results

The results contain an array of prediction objects with class names and confidence scores.

Displaying Results

Finally, we can display the top predictions in our app UI:

// Display top predictions <div className=”predictions”> { => { return ( <div key={p.className}> {p.className}: {p.probability.toFixed(3)} </div> ) })} </div>

And that’s it! Together with some styling, we have a working image classifier in React with TensorFlow.js. The same approach can be extended to other ML models and tasks.
