## What it is
react-cool-virtual is a tiny React hook for efficiently rendering large lists and datasets using DOM recycling (virtualization). It supports fixed, variable, and dynamic item sizes, infinite scroll, sticky headers, smooth scrolling, and server-side rendering.

## Use cases
- render a list with millions of rows without freezing the browser
- implement infinite scroll with load-more callbacks and skeleton screens
- build a chat UI that sticks to the bottom and pre-pends messages
- create a virtualized table or grid with dynamic row heights
- server-render a large list for better SEO and first paint
- build a virtualized carousel or feed with responsive sizing

## When to choose
- you need a lightweight, hook-based virtualizer for React lists, tables, grids, or feeds
- you need dynamic or real-time resizing of items
- you need SSR support or sticky headers out of the box

## When to avoid
- you are not using React
- you need virtualization for a framework like Vue or Svelte
- you need windowing for complex non-list layouts the hook API cannot express

## Facets
- artifact type: library
