## What it is
A Babel plugin that transforms React's styleName attribute into className at compile time using CSS module resolution. It offers much lower runtime overhead and bundle size than the runtime react-css-modules alternative.

## Use cases
- use css modules in react without runtime overhead
- resolve styleName to className at build time
- speed up react css modules performance
- reduce bundle size compared to react-css-modules
- support dynamic styleName resolution in react components
- migrate from react-css-modules to a babel-based approach

## When to choose
- you use React with CSS Modules and want minimal runtime cost
- you need a small footprint alternative to react-css-modules
- your build pipeline already uses Babel

## When to avoid
- your project does not use Babel
- you need actively maintained software with timely bug fixes
- you use modern CSS Modules support built into bundlers like webpack or Vite
