GraphQL is one of the latest front-end development technologies that have many uptakes. It's a query language for server-to-server communication, allowing developers to write self-describing code that is easier to read. This makes it perfect for building user interfaces. GraphQL enables you to access data quickly and easily without going back and forth between layers of code.
If you want to improve your eCommerce website's checkout process, consider using GraphQL.Using this technology, you can ensure that all checkout-related data is maintained in a single location, making it easier for customers to utilise your website. In addition, GraphQL makes it easy to handle errors and keep track of what's happening during the checkout process..
Step 1 : Create Empty Cart
First, use a GraphQL mutation to create an empty cart for the customer. This will initialize the cart object and assign it a unique identifier.
To create an empty cart for a guest, use the following example.
Next, implement a mutation to add products to the cart. You can pass the product IDs and quantities as arguments to the modification to populate the cart with the desired items.
If the customer is a guest, provide an input field to capture their email address. Use a mutation to set the guest's email on the cart, allowing for communication and order tracking.
You can skip this step if you have already placed the order as a registered customer. However, you must set a quote email address if you purchased a guest user. To do this, use the setGuestEmailOnCart mutation query. Remember to input the unique shopping cart ID from the previous step, { CART_ID }.1. Create an empty cart.
The following mutation adds a guest email to the shopping cart.
By following this comprehensive guide, you can leverage the power of GraphQL to build a robust and efficient cart checkout system. Feel free to customize and adapt the implementation to your requirements and business needs.
