8-bit components wrap shadcn/ui components rather than replacing them. This pattern maintains compatibility while adding retro styling.
Basic Wrapper Pattern
Structure:
- Import base component with alias
- Define variants using class-variance-authority
- Export separate interface for props
- Use ref prop (not forwardRef for React 19)
```tsx
import { type VariantProps, cva } from "class-variance-authority";
import { cn } from "@/lib/utils";
import { Button as ShadcnButton } from "@/components/ui/button";
import "@/components/ui/8bit/styles/retro.css";
export const buttonVariants = cva("", {
variants: {
font: {
normal: "",
retro: "retro",
},
variant: {
default: "bg-foreground",
// ...
},
},
defaultVariants: {
variant: "default",
size: "default",
},
});
export interface BitButtonProps
extends React.ButtonHTMLAttributes,
VariantProps {
asChild?: boolean;
ref?: React.Ref;
}
function Button({ children, asChild, ...props }: BitButtonProps) {
const { variant, size, className, font } = props;
return (
{...props}
className={cn(
"rounded-none active:translate-y-1 transition-transform",
className
)}
size={size}
variant={variant}
asChild={asChild}
>
{children}
);
}
```
Re-exporting Base Components
For components with multiple sub-components, re-export unchanged parts:
```tsx
import {
Dialog as ShadcnDialog,
DialogHeader as ShadcnDialogHeader,
DialogFooter as ShadcnDialogFooter,
DialogDescription as ShadcnDialogDescription,
} from "@/componentsconst Dialog = ShadcnDialog;
const DialogHeader =/ui/dialog";
ShadcnDialogHeader;
const DialogFooter = ShadcnDialogFooter;
const DialogDescription = ShadcnDialogDescription;
export {
Dialog,
DialogHeader,
DialogFooter,
DialogDescription,
// ...custom implementations
};
```
Card Wrapper Pattern
Use outer wrapper for pixelated borders while keeping base component:
```tsx
function Card({ className, font, ...props }: BitCardProps) {
return (
className={cn(
"relative border-y-6 border-foreground dark:border-ring !p-0",
className
)}
>
{...props}
className={cn(
"rounded-none border-0 !w-full",
font !== "normal" && "retro",
className
)}
/>
{/ Pixelated side borders /}
className="absolute inset-0 border-x-6 -mx-1.5 border-foreground dark:border-ring pointer-events-none"
aria-hidden="true"
/>
