Comparing with Radix / shadcn

If you’re already familiar with Radix UI and shadcn/ui, this guide highlights the small differences and similarities so you can get started with coss ui quickly.

Quick Checklist

• Replace asChild → render on AlertDialogTrigger and closing buttons
• Replace AlertDialogAction and AlertDialogCancel → AlertDialogClose
• Prefer AlertDialogPopup; AlertDialogContent remains for legacy
• If you used asChild on any other parts, switch to the render prop

Comparison Example

<span data-lib="radix-ui"> ```tsx title="shadcn/ui" // [!code word:asChild] // [!code word:AlertDialogCancel] // [!code word:AlertDialogAction] <AlertDialog> <AlertDialogTrigger asChild> <Button variant="outline">Show Dialog</Button> </AlertDialogTrigger> <AlertDialogContent> <AlertDialogHeader> <AlertDialogTitle>Are you absolutely sure?</AlertDialogTitle> <AlertDialogDescription> This action cannot be undone. This will permanently delete your account and remove your data from our servers. </AlertDialogDescription> </AlertDialogHeader> <AlertDialogFooter> <AlertDialogCancel>Cancel</AlertDialogCancel> <AlertDialogAction>Continue</AlertDialogAction> </AlertDialogFooter> </AlertDialogContent> ``` </span> <span data-lib="base-ui"> ```tsx title="coss ui" // [!code word:render] // [!code word:AlertDialogClose] <AlertDialog> <AlertDialogTrigger render={<Button variant="outline" />}> Show Dialog </AlertDialogTrigger> <AlertDialogPopup> <AlertDialogHeader> <AlertDialogTitle>Are you absolutely sure?</AlertDialogTitle> <AlertDialogDescription> This action cannot be undone. This will permanently delete your account and remove your data from our servers. </AlertDialogDescription> </AlertDialogHeader> <AlertDialogFooter> <AlertDialogClose render={<Button variant="ghost" />}> Cancel </AlertDialogClose> <AlertDialogClose render={<Button variant="destructive" />}> Continue </AlertDialogClose> </AlertDialogFooter> </AlertDialogPopup> ``` </span>
