react-window is a React component library that virtualizes large lists and tabular data by rendering only the visible rows, avoiding the DOM overhead of rendering thousands of elements at once. It is a small, focused, widely adopted windowing library used in projects such as React DevTools and the Replay browser.

Use cases

• render a very large list in React without lag
• virtualize long lists or grids so only visible rows are in the DOM
• display thousands of table rows efficiently in a React app
• fix React performance problems caused by rendering many items
• build fast infinite-scrolling lists in React
• render variable-height rows and tabular data with windowing

When to choose

• You use React and need to render lists, grids, or tables with thousands of rows while keeping scrolling smooth
• You want a lightweight, focused virtualization library with a simple component API instead of a heavyweight suite
• You need fixed-size or variable-size row virtualization with good TypeScript support

When to avoid

• You are not using React; this library is React-specific
• Your lists are small enough that rendering them directly performs fine, and adding virtualization is unnecessary complexity
• You need advanced virtualization features like masonry layouts or built-in infinite data loading that other libraries such as react-virtuoso or react-virtualized handle better
