DCheckoutStep

Show Suggested Answer

Suggested Answer: D

To implement a custom child checkout component to modify out-of-the-box functionality in an LWR checkout flow, the developer must implement the CheckoutStep interface. This interface defines the contract between the child component and the parent Checkout component, and allows the child component to communicate with the checkout flow. The developer must implement the methods of this interface, such as getStepName, getStepLabel, getStepStatus, validateStep, and so on. The developer can also use the @wire(CheckoutApi) decorator to access the checkout API methods and data.Reference:

I thought the answer was to throw some Lightning Bolts at the code until it works. That's the true developer's way, isn't it?

Yeah, the 'LightningElement' interface is what the developer needs to implement for the custom child checkout component.

Haha, throwing Lightning Bolts won't work this time. The 'LightningElement' interface is the key.

Wait, is the answer 'Implement the 'DeveloperMagicInterface' and wave a wand? That's how I usually solve my LWR problems!

The interface they need is definitely the `LightningComponentInterface`. It's the one that gives you all the lifecycle hooks and stuff to build your custom checkout component. Easy peasy!

Hmm, I'm not too sure about this one. Is it the `CheckoutComponentInterface` or something like that? The LWR stuff can get a bit tricky sometimes.

I think the `LightningElementInterface` is the one they're looking for. Gotta make sure the component follows the LWR guidelines, you know?

The developer needs to implement the `LightningElement` interface to create a custom child checkout component. That's the standard interface for building LWR components, right?
