## What it is
ReactShadow (npm: react-shadow) is a small React library for creating Shadow DOM roots declaratively via components like root.div, giving full style encapsulation within React apps. It supports styled-components and emotion integration so their styles are scoped to the shadow boundary.

## Use cases
- encapsulate styles in react components with shadow dom
- prevent css leaking between react components
- use styled-components inside shadow dom
- build isolated embeddable react widgets
- scope css to a component boundary in react

## When to choose
- you need true style isolation in a React app
- you're building embeddable widgets that must not clash with host page CSS
- you want declarative Shadow DOM without leaving JSX

## When to avoid
- you only need CSS modules or scoped class names rather than real encapsulation
- your app must support very old browsers without Shadow DOM
- you don't use React
