Component Wrapper Architecture

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)

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<HTMLButtonElement>, VariantProps<typeof buttonVariants> { asChild?: boolean; ref?: React.Ref<HTMLButtonElement>; }

function Button({ children, asChild, ...props }: BitButtonProps) { const { variant, size, className, font } = props;

return ( <ShadcnButton {...props} className={cn( "rounded-none active:translate-y-1 transition-transform", className )} size={size} variant={variant} asChild={asChild} > {children} </ShadcnButton> ); }

Re-exporting Base Components

For components with multiple sub-components, re-export unchanged parts:

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:

function Card({ className, font, ...props }: BitCardProps) { return ( <div className={cn( "relative border-y-6 border-foreground dark:border-ring !p-0", className )} > <ShadcnCard {...props} className={cn( "rounded-none border-0 !w-full", font !== "normal" && "retro", className )} />

  {/* Pixelated side borders */}
  <div
    className="absolute inset-0 border-x-6 -mx-1.5 border-foreground dark:border-ring pointer-events-none"
    aria-hidden="true"
  />
</div>

); }

Key Principles

• Alias imports - Use as ShadcnComponent pattern for base components

• Empty cva base - Variants often start empty, relying on CSS for styling

• Separate prop interface - Export BitComponentProps for TypeScript

• React 19 ref - Use ref?: React.Ref<T> instead of forwardRef

• rounded-none - Remove all border radius from base component

• Pass through props - Forward all props including size , variant , className

• Conditional retro - Use font !== "normal" && "retro" pattern

Component Examples

• components/ui/8bit/button.tsx

• Basic wrapper with pixel borders

• components/ui/8bit/card.tsx

• Card with outer wrapper

• components/ui/8bit/dialog.tsx

• Multi-subcomponent wrapper
