Installation#

1. Install the dependencies

   npm install class-variance-authority cn radix-ui

2. Copy the source into your project

   components/ui/badge.tsx

   import * as React from "react"import { cva, type VariantProps } from "class-variance-authority"import { cn } from "cn"import { Slot } from "radix-ui"const badgeVariants = cva(  "group/badge inline-flex h-5 w-fit shrink-0 items-center justify-center gap-1 overflow-hidden rounded-4xl border border-transparent px-2 py-0.5 text-xs font-medium whitespace-nowrap transition-all focus-visible:border-ring focus-visible:ring-[3px] focus-visible:ring-ring/50 has-data-[icon=inline-end]:pr-1.5 has-data-[icon=inline-start]:pl-1.5 aria-invalid:border-destructive aria-invalid:ring-destructive/20 dark:aria-invalid:ring-destructive/40 [&>svg]:pointer-events-none [&>svg]:size-3!",  {    variants: {      variant: {        default: "bg-primary text-primary-foreground [a]:hover:bg-primary/80",        secondary:          "bg-secondary text-secondary-foreground [a]:hover:bg-secondary/80",        destructive:          "bg-destructive/10 text-destructive focus-visible:ring-destructive/20 dark:bg-destructive/20 dark:focus-visible:ring-destructive/40 [a]:hover:bg-destructive/20",        outline:          "border-border text-foreground [a]:hover:bg-muted [a]:hover:text-muted-foreground",        ghost:          "hover:bg-muted hover:text-muted-foreground dark:hover:bg-muted/50",        link: "text-primary underline-offset-4 hover:underline",      },    },    defaultVariants: {      variant: "default",    },  })function Badge({  className,  variant = "default",  asChild = false,  ...props}: React.ComponentProps<"span"> &  VariantProps<typeof badgeVariants> & { asChild?: boolean }) {  const Comp = asChild ? Slot.Root : "span"  return (    <Comp      data-slot="badge"      data-variant={variant}      className={cn(badgeVariants({ variant }), className)}      {...props}    />  )}export { Badge, badgeVariants }

3. Make sure the foundation is in place

   Components read their colors, radius and surfaces from the tokens in app/globals.css. See Theming.
