Build a Cryptocurrency Dashboard with React: Fetching API Data for Real-Time Updates

Cryptocurrency is a hot topic in the world of finance, and keeping track of the rapidly changing prices can be a full-time job. In this tutorial, we will show you how to build a real-time cryptocurrency dashboard using React and fetching data from a cryptocurrency API.

Step 1: Setting Up Your React App

To get started, create a new React app using your preferred method. You can use create-react-app or set up a new React project from scratch. Once your app is set up, you will need to install axios, a popular JavaScript library for making API requests.

    npm install axios
    

Step 2: Fetching Data from the Cryptocurrency API

Next, you will need to fetch data from a cryptocurrency API. There are several APIs available for cryptocurrency data, such as CoinGecko or CoinMarketCap. In this example, we will use the CoinGecko API to fetch real-time cryptocurrency prices.

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

    const CryptoDashboard = () => {
        const [cryptoData, setCryptoData] = useState([]);

        useEffect(() => {
            const fetchData = async () => {
                const response = await axios.get('https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd');
                setCryptoData(response.data);
            }
            fetchData();
        }, []);

        return (
            <div>
                <h1>Bitcoin Price: $ {cryptoData.bitcoin ? cryptoData.bitcoin.usd : 'Loading...'}</h1>
            </div>
        );
    }

    export default CryptoDashboard;
    

Step 3: Displaying Real-Time Cryptocurrency Prices

Now that you have fetched the data from the API, you can display it in your dashboard. In this example, we are displaying the real-time price of Bitcoin in USD. You can expand this dashboard to include other cryptocurrencies or additional data points.

With this simple example, you can build a fully functional cryptocurrency dashboard that updates in real-time. You can customize the layout, styling, and data displayed to fit your specific needs. Happy coding!
