## What it is
A React library that automatically maps class names to CSS Modules inside React components, enabling locally scoped, modular CSS. It is deprecated in favor of the lighter babel-plugin-react-css-modules alternative.

## Use cases
- scope CSS class names in React components
- map style objects to CSS modules automatically
- use CSS Modules with webpack or Browserify
- compose and extend component styles with SASS or LESS
- handle multiple CSS modules per component

## When to choose
- maintaining a legacy React codebase already using react-css-modules
- needing runtime style mapping features not covered by babel-plugin-react-css-modules

## When to avoid
- starting a new React project - use babel-plugin-react-css-modules or native CSS Modules instead
- needing minimal bundle size or low performance overhead
- requiring active maintenance or modern React compatibility

## Facets
- artifact type: library
- maturity: abandoned
- function: css-framework, ui-components
- domain: frontend, web-development
- platform: browser, cross-platform
- tags: react, css-modules, deprecated, style-scoping, webpack, nodejs
