majiayu000 Figma to React - Production-Ready Component Generator
🎯 Purpose
Extract complete, lossless design information from Figma and generate production-ready React/Next.js components with TypeScript and Tailwind CSS.
🚨 CRITICAL RULES - Read First!
Rule 1: NEVER Truncate Code
Use 100% of Figma MCP output. Every className, every property matters.
// ✅ CORRECT: Keep ALL className from Figma MCP
<div className="absolute font-source-serif h-[108px] leading-[1.8] left-[100px] not-italic text-[20px] text-[rgba(29,38,45,0.8)] text-justify top-[210px] w-[1096px] whitespace-pre-wrap">
// ❌ WRONG: Removing any className
<div className="absolute left-[100px] top-[210px] font-source-serif text-[20px]">
Rule 2: Flatten absolute contents Structures
🔥 CRITICAL: Figma MCP returns nested absolute contents containers. display: contents makes the parent "disappear" - children are positioned relative to the nearest positioned ancestor (root)!
Key Insight: Children's positions are ALREADY absolute - DO NOT add parent's top/left!
// ❌ WRONG: Figma MCP output (has redundant parent wrapper)
<div className="absolute contents left-0 top-[41px]">
<p className="absolute left-[100px] top-[41px]">TITLE</p>
<div className="absolute left-0 top-[100px]">Line</div>
</div>
// ✅ CORRECT: Just remove the parent wrapper, keep children's positions AS-IS
<>
<p className="absolute left-[100px] top-[41px]">TITLE</p>
<div className="absolute left-0 top-[100px] w-[1920px] h-[1px] bg-[#C5CBCE] opacity-30" />
</>
Position Handling Rules:
| Parent Type | Child Position | Action |
|---|---|---|
absolute contents |
Child has own top/left |
Keep child position AS-IS, just remove parent |
absolute (no contents) |
Child has relative top/left |
Calculate: parent + child |
relative |
Child has top/left |
Calculate: parent + child |
🔥 The Golden Rule:
If parent has "contents" class → Child positions are already absolute → Keep AS-IS
If parent has NO "contents" class → Child positions are relative → Add parent + child
Reference: Verified correct positions (from production HTML):
- Header text:
top-[41px](not 82px) - Header line:
top-[100px](not 141px) - Footer line:
top-[980px] - Page number:
top-[1004px]
Rule 3: Extract Dimensions from Metadata
NEVER hardcode dimensions!
// 1. Get metadata first
const metadata = await mcp__figma__get_metadata({
fileKey: 'xxx',
nodeId: '11:1420'
})
// 2. Extract from XML
// <frame width="1920" height="1080">
const pageWidth = 1920
const pageHeight = 1080
// 3. Use extracted values
<div className="w-[1920px] h-[1080px]">
Rule 4: Font Loading & Name Mapping
🔥 CRITICAL: Use Google Fonts CDN directly, NOT next/font/google!
next/font/google generates CSS variables and self-hosts fonts, but the font rendering may differ from reference HTML that uses Google Fonts CDN directly. This causes:
- Different character widths (text wrapping issues)
- Different optical size handling for variable fonts
4.1 Font Loading (layout.tsx)
// ❌ WRONG: Using next/font/google
import { Source_Serif_4, Kaisei_Tokumin } from 'next/font/google'
const sourceSerif = Source_Serif_4({ subsets: ['latin'], variable: '--font-source-serif' })
// This may render fonts differently than Google Fonts CDN!
// ✅ CORRECT: Use Google Fonts CDN directly in layout.tsx
export default function RootLayout({ children }: { children: React.ReactNode }) {
return (
<html lang="en">
<head>
<link rel="preconnect" href="https://fonts.googleapis.com" />
<link rel="preconnect" href="https://fonts.gstatic.com" crossOrigin="anonymous" />
<link
href="https://fonts.googleapis.com/css2?family=Source+Serif+4:ital,opsz,wght@0,8..60,200..900;1,8..60,200..900&family=Kaisei+Tokumin:wght@400;500;700;800&display=swap"
rel="stylesheet"
/>
</head>
<body>{children}</body>
</html>
)
}
Key: Include opsz (optical size) axis for Source Serif 4 - this affects character widths!
4.2 Font CSS (globals.css)
@layer utilities {
/* Use direct font-family names, NOT CSS variables */
.font-source-serif {
font-family: 'Source Serif 4', serif;
}
.font-kaisei {
font-family: 'Kaisei Tokumin', serif;
}
}
4.3 Font Name Mapping
// Figma MCP returns:
font-['Kaisei_Tokumin:ExtraBold',sans-serif]
font-['Source_Serif_Pro:SemiBold',sans-serif]
// ✅ Convert to Tailwind classes:
font-kaisei font-extrabold
font-source-serif font-semibold
// Font name corrections (Google Fonts 2024):
'Source Serif Pro' → 'Source Serif 4'
'Source Sans Pro' → 'Source Sans 3'
4.4 Font Weight Mismatch Warning
⚠️ Figma's font weight names may NOT match CSS font-weights!
Figma renders fonts differently than browsers. What Figma calls "Bold" might visually appear lighter than CSS font-weight: 700.
| Figma Weight Name | Expected CSS | May Actually Need |
|---|---|---|
| Regular | 400 | 400 |
| Medium | 500 | 500 |
| Bold | 700 | 500 or 600 (test visually!) |
| ExtraBold | 800 | 700 (test visually!) |
Solution: Always compare with Figma screenshot. If text looks too bold, try one weight lighter:
font-bold(700) → tryfont-medium(500)font-extrabold(800) → tryfont-bold(700)
Rule 5: Critical CSS
Must add to globals.css:
body {
overflow-x: auto; /* Allow horizontal scroll */
}
.page-container {
min-width: max-content; /* Prevent compression */
display: inline-block; /* Keep layout intact */
}
Rule 6: Replace Simple Images with CSS
Optimize line images:
// ❌ Before: Image-based line
<div className="absolute h-0 left-0 top-[100px] w-[1920px]">
<div className="absolute inset-[-1px_0_0_0]">
<img src={imgLine} />
</div>
</div>
// ✅ After: CSS-based line
<div className="absolute left-0 top-[141px] w-[1920px] h-[1px] bg-[#C5CBCE] opacity-30" />
Rule 7: Inline SVG Assets
// ❌ Before: External image
<img src={imgVector} />
// ✅ After: Inline SVG
<svg viewBox="0 0 35 34" fill="none">
<path d="M17.5 0L0 34..." fill="#1d262d"/>
</svg>
Rule 7.5: Remove Fixed Heights from Text Blocks
🔥 CRITICAL: Figma MCP outputs fixed heights for text blocks, but this causes line-wrapping issues!
Font metrics differ between Figma's rendering and browser rendering (even with the same font family). Fixed heights can cause:
- Text overflow or clipping
- Different line counts than expected
- Layout breaks when font rendering differs slightly
// ❌ WRONG: Figma MCP output with fixed height
<p className="absolute h-[72px] leading-[1.8] left-[100px] text-[20px] top-[570px] w-[1096px]">
Long text that might wrap differently in browser...
</p>
// ✅ CORRECT: Remove h-[Xpx], let text flow naturally
<div className="absolute leading-[1.8] left-[100px] text-[20px] top-[570px] w-[1096px]">
<p className="mb-0">Long text that might wrap differently in browser...</p>
</div>
When to keep fixed heights:
- Container elements (cards, boxes) - keep dimensions
- Table rows with single-line content - keep
h-[34px] - Images and icons - keep dimensions
When to remove fixed heights:
- Multi-line text paragraphs - ALWAYS remove
h-[Xpx] - Text blocks with
text-justify- especially important - Any text that could wrap differently
Pattern: Use <div> wrapper with <p className="mb-0">:
// This matches reference HTML structure and ensures proper text flow
<div className="absolute font-source-serif leading-[1.8] left-[100px] text-[20px] top-[570px] w-[1096px]">
<p className="mb-0">Text content here...</p>
</div>
