App Example Using the Catalogue APIs
Let’s create a simple application that utilizes the catalogue APIs discussed above.
Set Up
First, ensure you have a server running with the catalogue API endpoints defined. Here, we’ll use a Node.js application as an example.
Frontend Component
This example uses HTML and JavaScript to interact with the catalogue APIs.
<html>
<head>
<title>Catalogue App</title>
</head>
<body>
<h1>Catalogue</h1>
<div id="items"></div>
<script>
fetch('/api/catalogue/items')
.then(response => response.json())
.then(data => {
const itemsDiv = document.getElementById('items');
data.forEach(item => {
const itemDiv = document.createElement('div');
itemDiv.innerHTML = `${item.name} - $${item.price}`;
itemsDiv.appendChild(itemDiv);
});
});
</script>
</body>
</html>
And that’s a wrap on our comprehensive guide to the catalogue with various API examples. Understanding and implementing these APIs can greatly enhance how you manage and display your content.
