name: dark-mode-gen description: Add dark mode support to components. Use when implementing dark theme.

Dark Mode Generator

Adding dark mode means updating every component with CSS variables or Tailwind dark: prefixes. This tool does it automatically for single files or entire directories.

One command. Zero config. Just works.

Quick Start

npx ai-dark-mode ./src/components/Card.tsx

What It Does

• Adds dark mode styles to React components
• Works with CSS variables, Tailwind, or styled-components
• Handles prefers-color-scheme media queries
• Preserves existing styles and structure

Usage Examples

# Single component
npx ai-dark-mode ./src/components/Card.tsx

# Entire directory
npx ai-dark-mode ./src/components/

# Preview before writing
npx ai-dark-mode ./src/components/Card.tsx --dry-run

Best Practices

• Use CSS variables - easier to maintain than hardcoded colors
• Test both modes - make sure contrast is good in both
• Don't forget images - some graphics need light/dark variants
• Respect system preference - use prefers-color-scheme

When to Use This

• Adding dark mode to an existing project
• Converting components that only have light styles
• Standardizing dark mode implementation across files
• Quick prototyping with dark mode support

Requirements

No install needed. Just run with npx. Node.js 18+ recommended. Needs OPENAI_API_KEY environment variable.

npx ai-dark-mode --help

How It Works

Reads your component files, identifies color definitions and styles, then adds appropriate dark mode variants. For Tailwind it adds dark: prefixes. For CSS it uses CSS variables with prefers-color-scheme.
