Design to React

Convert design component specifications to React components.

Overview

This skill transforms design specifications into idiomatic React components with TypeScript support, proper prop interfaces, and flexible styling approaches.

This skill covers:

• Converting design frames to React component hierarchy
• Mapping design properties to CSS/styled-components
• Generating TypeScript interfaces for props
• Creating Storybook stories for documentation

This skill does NOT cover:

• Design token extraction (see design-tokens-extraction skill)
• State management (Redux, Zustand, etc.)
• Data fetching and API integration

Quick Reference

Design to React Mapping

Design Element	React Component
Frame/Group	<div> with className
Auto-layout horizontal	Flexbox flex-direction: row
Auto-layout vertical	Flexbox flex-direction: column
Text	<span> or <p>
Rectangle	<div> with border-radius
Image	<img> or CSS background
Button	<button>
Input	<input>

Styling Approaches

Approach	When to Use
CSS Modules	Default, good isolation
styled-components	Dynamic styling needs
Tailwind	Project uses Tailwind
Inline styles	Simple, one-off styles

Workflow: Convert Design Component

Step 1: Analyze Design Structure

Read the design component and identify:

• Component hierarchy and nesting
• Layout direction and spacing
• Interactive elements
• Variants and states

Step 2: Generate TypeScript Interface

interface ComponentNameProps {
  /** Primary content */
  title: string;
  /** Optional secondary content */
  subtitle?: string;
  /** Size variant */
  size?: 'small' | 'medium' | 'large';
  /** Click handler */
  onClick?: () => void;
  /** Additional CSS classes */
  className?: string;
}

Step 3: Generate Component Code

With CSS Modules:

import React from 'react';
import styles from './ComponentName.module.css';
import clsx from 'clsx';

interface ComponentNameProps {
  title: string;
  subtitle?: string;
  size?: 'small' | 'medium' | 'large';
  onClick?: () => void;
  className?: string;
}

export const ComponentName: React.FC<ComponentNameProps> = ({
  title,
  subtitle,
  size = 'medium',
  onClick,
  className,
}) => {
  return (
    <div
      className={clsx(styles.container, styles[size], className)}
      onClick={onClick}
      role={onClick ? 'button' : undefined}
      tabIndex={onClick ? 0 : undefined}
    >
      <span className={styles.title}>{title}</span>
      {subtitle && <span className={styles.subtitle}>{subtitle}</span>}
    </div>
  );
};

CSS Module:

.container {
  display: flex;
  flex-direction: column;
  padding: var(--spacing-md);
  background: var(--color-surface);
  border-radius: var(--radius-md);
  cursor: pointer;
  transition: background-color var(--duration-fast);
}

.container:hover {
  background: var(--color-surface-hover);
}

.title {
  font: var(--font-body-medium);
  color: var(--color-text);
}

.subtitle {
  font: var(--font-body-small);
  color: var(--color-text-secondary);
}

/* Size variants */
.small {
  padding: var(--spacing-sm);
}

.medium {
  padding: var(--spacing-md);
}

.large {
  padding: var(--spacing-lg);
}

With styled-components:

import React from 'react';
import styled from 'styled-components';

interface ContainerProps {
  $size: 'small' | 'medium' | 'large';
}

const Container = styled.div<ContainerProps>`
  display: flex;
  flex-direction: column;
  padding: ${({ $size }) => {
    switch ($size) {
      case 'small': return 'var(--spacing-sm)';
      case 'large': return 'var(--spacing-lg)';
      default: return 'var(--spacing-md)';
    }
  }};
  background: var(--color-surface);
  border-radius: var(--radius-md);
  cursor: pointer;
  transition: background-color var(--duration-fast);

  &:hover {
    background: var(--color-surface-hover);
  }
`;

const Title = styled.span`
  font: var(--font-body-medium);
  color: var(--color-text);
`;

const Subtitle = styled.span`
  font: var(--font-body-small);
  color: var(--color-text-secondary);
`;

export const ComponentName: React.FC<ComponentNameProps> = ({
  title,
  subtitle,
  size = 'medium',
  onClick,
}) => {
  return (
    <Container $size={size} onClick={onClick}>
      <Title>{title}</Title>
      {subtitle && <Subtitle>{subtitle}</Subtitle>}
    </Container>
  );
};

Step 4: Generate Storybook Story

import type { Meta, StoryObj } from '@storybook/react';
import { ComponentName } from './ComponentName';

const meta: Meta<typeof ComponentName> = {
  title: 'Components/ComponentName',
  component: ComponentName,
  parameters: {
    layout: 'centered',
  },
  tags: ['autodocs'],
  argTypes: {
    size: {
      control: 'select',
      options: ['small', 'medium', 'large'],
    },
  },
};

export default meta;
type Story = StoryObj<typeof ComponentName>;

export const Default: Story = {
  args: {
    title: 'Component Title',
    subtitle: 'Supporting text',
  },
};

export const Small: Story = {
  args: {
    ...Default.args,
    size: 'small',
  },
};

export const Large: Story = {
  args: {
    ...Default.args,
    size: 'large',
  },
};

export const WithoutSubtitle: Story = {
  args: {
    title: 'Title Only',
  },
};

Common Patterns

Card Component

import React from 'react';
import styles from './Card.module.css';

interface CardProps {
  children: React.ReactNode;
  variant?: 'elevated' | 'outlined' | 'filled';
  padding?: 'none' | 'small' | 'medium' | 'large';
  onClick?: () => void;
}

export const Card: React.FC<CardProps> = ({
  children,
  variant = 'elevated',
  padding = 'medium',
  onClick,
}) => {
  const Component = onClick ? 'button' : 'div';

  return (
    <Component
      className={`${styles.card} ${styles[variant]} ${styles[`padding-${padding}`]}`}
      onClick={onClick}
    >
      {children}
    </Component>
  );
};

Button Component

import React from 'react';
import styles from './Button.module.css';

interface ButtonProps {
  children: React.ReactNode;
  variant?: 'primary' | 'secondary' | 'ghost';
  size?: 'small' | 'medium' | 'large';
  disabled?: boolean;
  loading?: boolean;
  leftIcon?: React.ReactNode;
  rightIcon?: React.ReactNode;
  onClick?: () => void;
}

export const Button: React.FC<ButtonProps> = ({
  children,
  variant = 'primary',
  size = 'medium',
  disabled = false,
  loading = false,
  leftIcon,
  rightIcon,
  onClick,
}) => {
  return (
    <button
      className={`${styles.button} ${styles[variant]} ${styles[size]}`}
      disabled={disabled || loading}
      onClick={onClick}
    >
      {loading && <span className={styles.spinner} />}
      {!loading && leftIcon && <span className={styles.icon}>{leftIcon}</span>}
      <span>{children}</span>
      {!loading && rightIcon && <span className={styles.icon}>{rightIcon}</span>}
    </button>
  );
};

Token Integration

Reference design tokens via CSS custom properties:

.component {
  /* Colors */
  background: var(--color-surface);
  color: var(--color-text);
  border-color: var(--color-border);

  /* Typography */
  font-family: var(--font-family-sans);
  font-size: var(--font-size-base);
  font-weight: var(--font-weight-medium);

  /* Spacing */
  padding: var(--spacing-md);
  gap: var(--spacing-sm);

  /* Shape */
  border-radius: var(--radius-md);
  box-shadow: var(--shadow-md);

  /* Motion */
  transition: all var(--duration-fast) var(--easing-default);
}

Naming Conventions

Design Name	React Component	File
Button/Primary	PrimaryButton or Button	Button.tsx
Card - Article	ArticleCard	ArticleCard.tsx
Input/Text Field	TextField	TextField.tsx
List Item/Default	ListItem	ListItem.tsx
