Cryptocurrencies, especially Bitcoin, have become a significant part of the financial market. For web developers and crypto enthusiasts, integrating real-time Bitcoin price tracking into a web application can be an exciting and valuable feature. In this post, we'll walk through how to fetch the current price of Bitcoin using ReactJS and the Kraken API.

Understanding the Kraken API

Kraken is a popular cryptocurrency exchange that offers a powerful API for accessing cryptocurrency data. Their public API doesn't require authentication, which makes it a great choice for retrieving Bitcoin's current price.

Setting Up Your ReactJS Project

First, you'll need to have Node.js installed on your computer. Once you have Node.js, you can create a new React application by running:

npx create-react-app bitcoin-price-tracker
cd bitcoin-price-tracker

Installing Axios

While React does have built-in methods to fetch data, we'll use Axios for its simplicity and ease of use. Install it by running:

npm install axios

Creating the Component

Now, let's create a simple component to display Bitcoin's current price. Create a new file called BitcoinPrice.js in your src folder.

import React, { useState, useEffect } from 'react';
import axios from 'axios';

const BitcoinPrice = () => {
    const [price, setPrice] = useState(null);

    useEffect(() => {
        const fetchPrice = async () => {
            try {
                const response = await axios.get('');
            } catch (error) {
                console.error('Error fetching data: ', error);

    }, []);

    return (
            <h1>Current Bitcoin Price</h1>
            <p>{price ? `$${price}` : 'Loading...'}</p>

export default BitcoinPrice;

In this component, we use useState to store the price and useEffect to fetch the price when the component mounts. The Axios get method is used to make a request to the Kraken API endpoint for the Bitcoin to USD ticker information.

Display the Component

Finally, let’s display our BitcoinPrice component. Update the App.js to include our new component.

import React from 'react';
import './App.css';
import BitcoinPrice from './BitcoinPrice';

function App() {
  return (
    <div className="App">
      <header className="App-header">
        <BitcoinPrice />

export default App;

Running the Application

Run your application:

npm start


This simple application demonstrates how you can use ReactJS and Axios to fetch and display real-time data from an API. By integrating the Kraken API, you can expand this application to include prices of other cryptocurrencies, historical data analysis, and much more.

Remember to always handle API responses and errors gracefully in a production application to ensure a robust and user-friendly experience. Happy coding!
