## What it is
A collection of codemod scripts for automatically updating React applications across versions, runnable via the codemod CLI or npx. It transforms source code (e.g., replacing ReactDOM.render with createRoot, removing forwardRef, converting createElement to JSX) using AST-based rewrites.

## Use cases
- upgrade a React app to React 19
- automatically replace deprecated ReactDOM.render with createRoot
- convert React.createElement calls to JSX
- migrate string refs to callback refs
- bulk-refactor forwardRef usage across a codebase
- update act imports for new React test APIs

## When to choose
- you are upgrading a React codebase across major versions and want automated migrations
- you need to apply repetitive mechanical refactors to many React files safely

## When to avoid
- you need one-off manual refactors on a handful of files
- your project does not use React
- you need transforms for frameworks other than React
