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

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

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

3. 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.)

4. Offer next steps:

   • Copy *-tailwind.config.js into their project
   • Import *-variables.css into their stylesheet
   • 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
