Code

The Code component has been removed in HeroUI v3. Use native HTML <code> element with Tailwind CSS classes instead.

Key Changes

1. Component Removal

v2: <Code> component from @heroui/react
v3: Native HTML <code> element with Tailwind classes

2. Variants Mapping

The v2 Code component had the following variants that need to be replaced:

v2 Variant	v3 Equivalent	Notes
`color="default"`	`bg-default/40 text-default-700`	Use Tailwind opacity utilities
`color="primary"`	`bg-accent/20 text-accent-600`	`primary` renamed to `accent`
`color="secondary"`	`bg-default/40 text-default-700`	Similar to default
`color="success"`	`bg-success/20 text-success-700`	Same color name
`color="warning"`	`bg-warning/20 text-warning-700`	Same color name
`color="danger"`	`bg-danger/20 text-danger-600`	Same color name
`size="sm"`	`text-sm`	Tailwind text size
`size="md"`	`text-base`	Tailwind text size
`size="lg"`	`text-lg`	Tailwind text size
`radius="none"`	`rounded-none`	Tailwind border radius
`radius="sm"`	`rounded-sm`	Tailwind border radius
`radius="md"`	`rounded-md`	Tailwind border radius
`radius="lg"`	`rounded-lg`	Tailwind border radius
`radius="full"`	`rounded-full`	Tailwind border radius

Structure Changes

In v2, Code was a component wrapper around the native <code> element:

import { Code } from "@heroui/react";

export default function App() {
  return <Code>npm install @heroui/react</Code>;
}

In v3, use the native <code> element directly with Tailwind CSS classes:

export default function App() {
  return (
    <code className="px-2 py-1 h-fit font-mono font-normal inline-block whitespace-nowrap rounded-sm bg-default/40 text-default-700 text-sm">
      npm install @heroui/react
    </code>
  );
}

Migration Examples

Variants

{/* Colors */}
<Code color="primary">Primary code</Code>
<Code color="success">Success code</Code>

{/* Sizes */}
<Code size="md">Medium code</Code>

{/* Colors */}
<code className="px-2 py-1 h-fit font-mono font-normal inline-block whitespace-nowrap rounded-sm bg-accent/20 text-accent-600 text-sm">
  Primary code
</code>
<code className="px-2 py-1 h-fit font-mono font-normal inline-block whitespace-nowrap rounded-sm bg-success/20 text-success-700 text-sm">

</code>

{/* Sizes */}
<code className="px-2 py-1 h-fit font-mono font-normal inline-block whitespace-nowrap rounded-sm bg-default/40 text-default-700 text-base">
  Medium code
</code>

Combined Variants

<Code color="primary" size="md" radius="lg">
  npm install @heroui/react
</Code>

<code className="px-2 py-1 h-fit font-mono font-normal inline-block whitespace-nowrap rounded-lg bg-accent/20 text-accent-600 text-base">
  npm install @heroui/react
</code>

Creating a Reusable Code Component (Optional)

If you use inline code frequently, you can create a simple wrapper component:

import { Code } from "@heroui/react";

<Code color="primary" size="md">Code snippet</Code>

// components/Code.tsx
import { cn } from "@/lib/utils"; // or your cn utility

interface CodeProps extends React.HTMLAttributes<HTMLElement> {
  color?: "default" | "accent" | "success" | "warning" | "danger";
  size?: "sm" | "md" | "lg";
  radius?: "none" | "sm" | "md" | "lg" | "full";
}

const colorClasses = {
  default: "bg-default/40 text-default-700",
  accent: "bg-accent/20 text-accent-600",
  success: "bg-success/20 text-success-700",
  warning: "bg-warning/20 text-warning-700",
  danger: "bg-danger/20 text-danger-600",
};

const sizeClasses = {
  sm: "text-sm",
  md: "text-base",
  lg: "text-lg",
};

const radiusClasses = {
  none: "rounded-none",
  sm: "rounded-sm",
  md: "rounded-md",
  lg: "rounded-lg",
  full: "rounded-full",
};

export function Code({
  children,
  className,
  color = "default",
  size = "sm",
  radius = "sm",
  ...props
}: CodeProps) {
  return (
    <code
      className={cn(
        "px-2 py-1 h-fit font-mono font-normal inline-block whitespace-nowrap",
        colorClasses[color],
        sizeClasses[size],
        radiusClasses[radius],
        className
      )}
      {...props}
    >
      {children}
    </code>
  );
}

// Usage
<Code color="accent" size="md">Code snippet</Code>

Base Styles Reference

The v2 Code component used these base styles that you should include:

px-2 - Horizontal padding
py-1 - Vertical padding
h-fit - Height fits content
font-mono - Monospace font family
font-normal - Normal font weight
inline-block - Inline block display
whitespace-nowrap - Prevent text wrapping

Summary

Component Removed: Code component no longer exists in v3
Import Change: Remove import { Code } from "@heroui/react"
Use Native Element: Replace with native <code> HTML element
Styling: Apply Tailwind CSS classes directly
Color Mapping: primary → accent in v3

Migration Steps

Remove Import: Remove Code from @heroui/react imports
Replace Component: Replace all <Code> instances with <code> elements
Add Tailwind Classes: Apply equivalent Tailwind classes for styling
Update Colors: Change color="primary" to use accent color classes
Optional: Create a reusable wrapper component if you use inline code frequently
