## What it is
A React library providing a KeepAlive component that preserves component state across unmounts, similar to Vue's keep-alive. It wraps components with a Provider to cache them and avoid repeated re-rendering, independent of React Router.

## Use cases
- preserve component state when switching tabs in a React app
- avoid re-rendering expensive components on navigation
- implement Vue-style keep-alive caching in React
- cache form state when users navigate away and back
- keep list scroll position and filters alive across route changes

## When to choose
- you need Vue-like keep-alive behavior in React
- you want caching that works without React Router
- you need CSS animations on cached components since it doesn't use display:none

## When to avoid
- you're on React 18+ with modern alternatives available
- your components are cheap to re-render and caching adds complexity
- you need actively maintained support for the latest React versions

## Facets
