Adding Ajax Add to Cart to a Shopify Theme

In this article, we will learn how to add Ajax functionality to a Shopify theme in order to enhance the user experience of adding items to the cart. Traditionally, when a user clicks on the "Add to Cart" button, the form is submitted and the user is redirected to the cart page. With Ajax, we can improve this process by performing the cart update in the background without refreshing the page.

Introduction

In the world of e-commerce, it is essential to provide a smooth and seamless shopping experience to customers. One of the core aspects of this experience is the ability to add items to the cart effortlessly. In this article, we will explore how to implement Ajax add to cart functionality in a Shopify theme, allowing users to add items to their cart without any interruptions.

What is AJAX?

AJAX stands for Asynchronous JavaScript and XML. It is a technology that allows you to send and receive data from a server asynchronously, without interfering with the user's current page. This means that instead of the user needing to refresh the page or navigate away, the data can be sent and received in the background, providing a more seamless and interactive experience.

Why use AJAX for adding items to the cart?

The traditional method of adding items to the cart involves submitting a form and redirecting the user to the cart page. While this method works perfectly fine, it can interrupt the user's shopping experience. By implementing Ajax add to cart functionality, we can update the cart in the background without any page refreshes, resulting in a more elegant and user-friendly interface.

Step 1: Setting up the basic structure

To begin with, we need to have a basic structure in place for our Shopify theme. This should include a header section with a cart icon and a product form with an "Add to Cart" button. We will also need to ensure that there is no JavaScript attached to the form, as we will be handling the submission with Ajax.

Step 2: Selecting the form and preventing default submission

In this step, we will select all the "Add to Cart" forms on the page using JavaScript. We will then add an event listener to each form to listen for the submit event. Inside the event listener, we will use the event.preventDefault() method to prevent the default form submission behavior.

Step 3: Submitting the form data with AJAX

Now that we have prevented the default form submission, we can proceed to submit the form data using Ajax. We will be using the fetch API to make a POST request to the "/cart/add" endpoint. To do this, we will create a new FormData object and pass in the form element. We will use the async/await syntax to ensure that the cart is updated before proceeding to the next step.

Step 4: Updating the cart count

Once we have successfully added the item to the cart, we need to update the cart count displayed in the header. To achieve this, we will select all the elements with the class "cart-count" and update their text content with the updated item count retrieved from the cart object.

Step 5: Displaying a notification message

To provide visual feedback to the user after adding an item to the cart, we will display a notification message. We will add a paragraph element with the class "added-to-cart" below the form. By default, this element will be hidden using the CSS property display: none.

Step 6: Adding the notification message dynamically

In the previous step, we statically added the notification message to the form. However, a more flexible approach would be to generate and inject the message dynamically using JavaScript. To achieve this, we will create a new paragraph element with the class "added-to-cart" and add the text content "Added to cart". We will then append this element to the form using the appendChild method.
