How can I modify the checkout code now that checkout.liquid is deprecated?

Hey! So, since checkout.liquid’s been deprecated, how can I change checkout code now? I’m looking into checkout extensibility but couldn’t find a resource that tells me how to change code for a core feature.

To be more specific, I’d like to add span tag to the line item title as well as to remove a string from the title when a certain condition is met. All that is pretty simple to achieve with liquid, but I can’t find a way to implement it. Does anyone have an idea of how this can be done or can direct me to a resource I can use?

Hi @Ryoshin ,

Checkout extension you need a partner account to create and deploy to your shop.

For your specific customization I would use Shopify Functions instead. https://shopify.dev/docs/api/functions/reference/cart-transform

Definitely find a partner to help you.
