React checkout page template
A one-page React checkout: contact, shipping address, delivery options and a credit card form beside the order summary, light and dark.
Install
One command writes the page, its design and its 4 sections into your project, as code you then own. It needs a
components.json, and the shadcn registry page has the one-time setup.Terminal
npx shadcn@latest add https://www.box-kite.dev/r/checkout-page.jsonSections
Each section is a block of its own, with its own page and its own install command.
Source
The page itself. Every style is a prop, so there is no stylesheet to copy with it, and each section it imports is on its own page above.

Design
What every page of this template shares: the built-in components restyled with
Box.createComponents(), applied to the subtree with <Box.Components>, so it stops at the edge of the store and the rest of your app keeps its own look.Store design

* The store's design: the built-in components restyled for this one brand, in light and dark. It registers
* nothing — `Box.createComponents()` returns a design, and `StoreSurface` applies it to its subtree only, so
