What will we learn
In this guide, we will learn how to:
- Use the fetch API to send a GET request to a remote endpoint
- Parse JSON into a javascript object/array
- Dynamically render HTML
Use Case
While we cannot list every use case, let us use the following example:
Assume you have an e-commerce site that needs to display products, each products represented by a card.
Before we move on, we need to design our card using HTML and CSS. Let’s go for something simple:
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<title>My E-Shop</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div>
<h1>Welcome!</h1>
<div id="cards-container">
<div class="card">
<div id="card-img-wrapper">
<img class="card-img" src="https://i.dummyjson.com/data/products/26/5.jpg" alt="">
</div>
<h3>Cool product</h3>
<p>$19.99</p>
<div id="card-btn-wrapper">
<button class="card-btn">BUY</button>
</div>
</div>
</div>
</div>
</body>
</html>
