Creating a real-time cryptocurrency price dashboard is an excellent way to learn modern web development techniques using Vue.js and Axios. This guide walks you through building a fully functional dashboard that fetches live crypto prices from an API, processes the data, and displays it in a clean, responsive interface — all using lightweight, widely adopted tools.
By the end of this tutorial, you’ll understand how to:
- Set up a Vue.js application
- Install and use Axios for API requests
- Fetch real-time cryptocurrency data
- Dynamically render data on the frontend
- Structure clean, maintainable code
Whether you're new to frontend development or brushing up on modern practices, this hands-on project delivers practical skills applicable to countless real-world scenarios.
Why Use Vue + Axios for Real-Time Data Apps?
Vue.js offers a gentle learning curve with powerful reactivity, making it ideal for dynamic user interfaces. Axios, a promise-based HTTP client, simplifies communication with RESTful APIs — essential for pulling live financial data like cryptocurrency prices.
Together, they form a robust stack for building data-driven applications without the complexity of larger frameworks.

Step 1: Set Up a Basic Vue Application
Start by creating a simple HTML file called index.html. This will serve as the foundation of your dashboard.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Crypto Price Dashboard</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/foundation.min.css" />
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.js"></script>
</head>
<body>
<div id="app" class="container">
<h1 class="text-center">Crypto Price Dashboard</h1>
<div class="grid-x grid-margin-x">
<div class="cell medium-4" v-for="(result, index) in results" :key="index">
<div class="card">
<div class="card-section">
<h4>{{ index }}</h4>
<p>¥ {{ result.CNY }}</p>
<p>$ {{ result.USD }}</p>
</div>
</div>
</div>
</div>
</div>
</body>
</html>This template includes:
- CDN links to Vue.js and Foundation CSS for styling
- A placeholder div (
#app) where Vue will mount - A loop (
v-for) to display multiple cryptocurrencies

Step 2: Separate JavaScript Logic
To keep your code organized, move the Vue logic into a separate file named vueApp.js.
First, remove the inline script from index.html and add:
<script src="vueApp.js"></script>Now create vueApp.js with initial mock data:
const vm = new Vue({
el: '#app',
data: {
results: {
BTC: { CNY: 73759.99, USD: 3166.21 },
ETH: { CNY: 33581.77, USD: 2336.25 },
LINK: { CNY: 182.62, USD: 26.49 }
}
}
});This modular approach separates concerns — HTML handles presentation, while JavaScript manages data. It's easier to debug and scale.
Step 3: Replace Mock Data with Live API Calls Using Axios
Now it’s time to fetch real-time cryptocurrency prices. We'll use the free CryptoCompare API:
https://min-api.cryptocompare.com/data/pricemulti?fsyms=BTC,ETH,LINK&tsyms=CNY,USDInstall Axios via CDN
Add Axios to your index.html before vueApp.js:
<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
<script src="vueApp.js"></script>Update vueApp.js to Use Axios
Replace the static data with an API call inside Vue’s mounted() lifecycle hook:
const url = "https://min-api.cryptocompare.com/data/pricemulti?fsyms=BTC,ETH,LINK&tsyms=CNY,USD";
new Vue({
el: '#app',
data: {
results: {}
},
mounted() {
axios.get(url)
.then(response => {
this.results = response.data;
})
.catch(error => {
console.error("Failed to fetch data:", error);
});
}
});When the page loads, Vue automatically calls the API and updates the UI with live prices — no manual DOM manipulation needed.

Step 4: Enhance Error Handling and UX
Improve reliability by adding loading states and error messages.
Update your data and template:
In vueApp.js
data: {
results: {},
loading: true,
error: null
},
mounted() {
axios.get(url)
.then(response => {
this.results = response.data;
})
.catch(err => {
this.error = "Unable to load crypto prices. Please try again later.";
console.error(err);
})
.finally(() => {
this.loading = false;
});
}In index.html (Add Conditional Rendering)
<div v-if="loading" class="callout info">Loading latest prices...</div>
<div v-if="error" class="callout alert">{{ error }}</div>
<div v-if="!loading && !error" class="grid-x grid-margin-x">
<!-- Existing card loop -->
</div>These small additions significantly improve user experience during network delays or failures.
Frequently Asked Questions (FAQ)
Q: What is Axios used for in Vue applications?
A: Axios is used to make HTTP requests to external APIs. In this project, it fetches real-time cryptocurrency prices so Vue can display them dynamically on the page.
Q: Can I use other APIs instead of CryptoCompare?
A: Yes! Any public JSON API works with Axios. Popular alternatives include CoinGecko and Binance Market Data APIs. Just adjust the URL and response handling accordingly.
Q: Is Axios better than Fetch for Vue projects?
A: Axios provides built-in JSON parsing, interceptors, and better error handling compared to the native Fetch API. For most Vue apps, Axios offers a smoother developer experience.
Q: How often does the price update?
A: In this version, prices load once when the page opens. To enable auto-updates every 30 seconds, wrap the axios.get() call in setInterval() inside mounted().
Q: Do I need Node.js or a build system?
A: No. This example runs entirely in the browser using CDNs. However, for larger projects, consider using npm and a bundler like Vite or Webpack.
Q: Can I add more cryptocurrencies?
A: Absolutely. Just add their symbols (e.g., ADA, DOT) to the fsyms parameter in the API URL. The response will include their prices automatically.
Advanced Axios Patterns You Should Know
Handle GET Requests with Parameters
axios.get('/api/data', {
params: { fsyms: 'BTC,ETH', tsyms: 'USD,EUR' }
});Send Headers (e.g., Authentication)
axios.get('/api/protected', {
headers: { 'Authorization': 'Bearer your-token' }
});POST Data to an Endpoint
axios.post('/api/save', { coin: 'BTC', alertPrice: 50000 });Use Async/Await Syntax
async mounted() {
try {
const response = await axios.get(url);
this.results = response.data;
} catch (error) {
this.error = "Request failed";
}
}This syntax improves readability, especially when chaining multiple API calls.

Final Thoughts
You’ve now built a fully functional real-time cryptocurrency price dashboard using Vue.js and Axios. You’ve learned how to:
- Initialize a Vue app
- Fetch data from a public API
- Handle responses and errors gracefully
- Present data in a responsive layout
These foundational skills are transferable to weather apps, stock trackers, news feeds, and more.
While coding gives you full control, remember that tools like OKX offer powerful pre-built solutions for tracking digital assets — ideal if you want instant access without development overhead.
With practice, you’ll be able to create sophisticated dashboards that pull from multiple APIs, support user preferences, and even send price alerts — all with confidence in your frontend toolkit.
