stitch-react-components（stitch React 组件）

Stitch → Vite / React Components

Constraint: Only use this skill when the user explicitly mentions "Stitch" and React (Vite, CRA, or just "React app" without Next.js).

You are a frontend engineer converting Stitch mobile/desktop designs into clean, modular React components using Vite + TypeScript. This skill targets plain React apps — not Next.js App Router. For Next.js, use stitch-nextjs-components instead.

When to use this skill vs. Next.js

Prerequisites

• Stitch MCP Server configured (or use downloaded HTML directly)
• Node.js + npm/pnpm
• Vite + React project initialized: npm create vite@latest my-app -- --template react-ts

Step 1: Retrieve the design

1. Run list_tools → find Stitch MCP prefix
2. Call [prefix]:get_screen with numeric projectId and screenId
3. Download HTML: bash scripts/fetch-stitch.sh "[htmlCode.downloadUrl]" "temp/source.html"
4. Check screenshot.downloadUrl — verify layout matches expectations

Step 2: Project structure

src/
├── components/           ← One file per component
│   └── [Name].tsx
├── data/
│   └── mockData.ts       ← Static content (never in components)
├── theme/
│   ├── tokens.ts         ← Design token constants
│   └── useTheme.ts       ← Dark mode hook
├── types/
│   └── index.ts          ← Shared TypeScript types
├── App.tsx               ← Root component
└── main.tsx              ← Entry point

Step 3: Extract design tokens

From the Stitch HTML <head>, find the tailwind.config or CSS variable definitions.

// src/theme/tokens.ts — extract hex values from Stitch HTML
export const lightTokens = {
  background: '#FFFFFF',
  surface:    '#F4F4F5',
  primary:    '#6366F1',
  primaryFg:  '#FFFFFF',
  text:       '#09090B',
  textMuted:  '#71717A',
  border:     '#E4E4E7',
} as const

export const darkTokens = {
  background: '#09090B',
  surface:    '#18181B',
  primary:    '#818CF8',
  primaryFg:  '#09090B',
  text:       '#FAFAFA',
  textMuted:  '#A1A1AA',
  border:     '#27272A',
} as const

export type ThemeTokens = typeof lightTokens

// src/theme/useTheme.ts
import { useEffect, useState } from 'react'
import { lightTokens, darkTokens, type ThemeTokens } from './tokens'

/**
 * Returns current theme tokens based on system color scheme.
 * Listens for system-level dark/light mode changes.
 */
export function useTheme(): ThemeTokens {
  const [isDark, setIsDark] = useState(
    () => window.matchMedia('(prefers-color-scheme: dark)').matches
  )

  useEffect(() => {
    const mq = window.matchMedia('(prefers-color-scheme: dark)')
    const handler = (e: MediaQueryListEvent) => setIsDark(e.matches)
    mq.addEventListener('change', handler)
    return () => mq.removeEventListener('change', handler)
  }, [])

  return isDark ? darkTokens : lightTokens
}

Step 4: Component conversion rules

Layout mapping

Tailwind class mapping

Use the Stitch HTML classes directly in JSX where they don't reference Stitch-specific tokens. Map Stitch tokens to CSS variables:

// Stitch HTML: bg-primary → CSS variable → Tailwind arbitrary value
// OR: use inline style with token value

// Option A — Tailwind arbitrary value (if custom tokens in tailwind.config)
<div className="bg-[--color-primary] text-[--color-primaryFg]">

// Option B — inline style with useTheme()
const theme = useTheme()
<div style={{ backgroundColor: theme.primary, color: theme.primaryFg }}>

Component template

// src/components/StitchComponent.tsx

/**
 * Props for StitchComponent — all data via props, never fetched inside.
 */
interface StitchComponentProps {
  /** Primary heading text */
  title: string
  /** Supporting description — optional */
  description?: string
  /** Primary action callback */
  onAction?: () => void
}

/**
 * StitchComponent — [describe purpose in one sentence]
 */
export function StitchComponent({
  title,
  description,
  onAction,
}: Readonly<StitchComponentProps>) {
  const theme = useTheme()

  return (
    <div
      className="rounded-xl border p-4 gap-2 flex flex-col"
      style={{
        backgroundColor: theme.surface,
        borderColor: theme.border,
      }}
    >
      <h3 className="text-base font-semibold" style={{ color: theme.text }}>
        {title}
      </h3>

      {description ? (
        <p className="text-sm" style={{ color: theme.textMuted }}>
          {description}
        </p>
      ) : null}

      {onAction ? (
        <button
          onClick={onAction}
          className="rounded-lg px-4 py-2 text-sm font-medium transition-opacity hover:opacity-90"
          style={{ backgroundColor: theme.primary, color: theme.primaryFg }}
          type="button"
        >
          Action
        </button>
      ) : null}
    </div>
  )
}

Step 5: Architectural rules

• One component per file — no single-file spaghetti
• Static data in src/data/mockData.ts — never hardcoded in JSX
• Shared types in src/types/index.ts
• Every component has Readonly<ComponentNameProps> interface
• No hardcoded hex colors — use useTheme() or CSS variables
• No any types

Step 6: Integration with shadcn/ui

After converting the Stitch design to base React components, you can layer in shadcn/ui:

npx shadcn@latest init    # Set up shadcn in your Vite project
npx shadcn@latest add button card input dialog

Then use stitch-shadcn-ui skill to replace raw HTML elements with shadcn components while preserving the Stitch design tokens.
