A React library that implements Vue's <keep-alive /> component caching behavior, preserving component state when they are unmounted and remounted. It works via a hack implementation compatible with React 16-18, Preact, and SSR.

Use cases

• preserve component state when switching tabs in react-router
• cache form input values when navigating away and back
• implement closable tabs that keep their state like in Vue
• keep list scroll position and filters when returning to a page
• cache multi-step wizard state across route changes

When to choose

• you need Vue-style keep-alive state preservation in a React app
• you're building tabbed interfaces where each tab must retain its state
• you're on React 16/17/18 and need component caching without rewriting to hooks

When to avoid

• you use React.StrictMode or ReactDOMClient.createRoot without disabling autoFreeze
• you can wait for or use React 18's official <Offscreen /> support
• your project doesn't use Babel and you can't manage cacheKey manually
