Shipping Options Dialog Block for React

So you can see it without a click. On load the dialog is a copy drawn in place over the cart: a native dialog element that isn't modal, so nothing is trapped, hidden or focused, and the page around the preview keeps working. The Change shipping button opens the real Dialog, modal, with its focus trap, Escape and focus return, and the copy stays closed until a reload. Both show the same ShippingFields component and share the block's draft, so a method chosen in the copy is chosen in the real one, and Cancel puts it back to what the cart has. In your app keep the Dialog and drop the copy: the "in-place" state, the scrim and the dialog element inside the frame.

By businessDay, a small helper that starts at the order date, AS_OF, and steps forward one calendar day at a time, counting only Monday to Friday. Each method has a fastest and a slowest number of business days, so Standard is 3 to 5, and the two results are written from typed weekday and month names, which keeps the text identical on the server and in every browser. Public holidays are not counted: in your app take the dates from your carrier's API or add your calendar of closed days to the helper. Change AS_OF and every date moves with it.

Every price is whole cents formatted with Intl.NumberFormat, so $4.99 is 499. The order total before shipping, SUBTOTAL, is a constant, and the line, the bar and Standard's price all come from it: below FREE_OVER the line says how much more to add and Standard costs its own price, at or above it Standard reads "Free". Adding the tea towel raises the total by its price so you can watch the line cross the threshold; the cart behind the dialog shows the new subtotal, shipping and total once you use a method.

Yes. The methods are native radio buttons in a group, so the arrow keys move between them and Tab leaves the group; the real dialog is named by its title and described by its sentence, focus starts on the chosen method and stays inside until the dialog closes, and Escape, Cancel and the close button return focus to Change shipping. The tea towel button says whether it is pressed, and what changed is said in a polite message. The trigger is passed to DialogTrigger through render, and the dialog is controlled with open and onOpenChange. The copy shown on load moves no focus; Escape inside it, Cancel and its close button close it and put focus on the button.

All of it. The methods, the carriers, the prices, the order total and the cart drawing are typed in this file, and Use Express only changes the drawn cart and says in a polite message that nothing ships. In your app load the methods and their prices from your carrier or checkout API for the person's address, keep businessDay only if your carrier gives you day counts rather than dates, and save the choice on the order from confirm.

The copy shown on load docks to the foot of the page as a bottom sheet, with the rows scrolling above the pinned Cancel and Use button. Each row keeps its name and price on one line and its dates and carrier under them, and the drawn cart keeps its totals under two items. The real dialog keeps the Dialog's own phone layout: a sheet stuck to the bottom of the screen.
