Extract Design Language

Extract the complete design language from any website URL. Generates 8 output files covering colors, typography, spacing, shadows, components, breakpoints, animations, and accessibility.

Prerequisites

Ensure designlang is available. Install if needed:

npm install -g designlang

Or use npx (no install required):

npx designlang <url>

Process

1. Run the extraction on the provided URL:

npx designlang <url> --screenshots

For multi-page crawling: npx designlang <url> --depth 3 --screenshots For dark mode: npx designlang <url> --dark --screenshots

1. Read the generated markdown file to understand the design:

cat design-extract-output/*-design-language.md

1. Present key findings to the user:

• Primary color palette with hex codes
• Font families in use
• Spacing system (base unit if detected)
• WCAG accessibility score
• Component patterns found
• Notable design decisions (shadows, radii, etc.)

• Paste *-shadcn-theme.css into globals.css for shadcn/ui users
• Import *-theme.js for React/CSS-in-JS projects
• Import *-figma-variables.json into Figma for designer handoff
• Open *-preview.html in a browser for a visual overview
