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
