## What it is
A lightweight, TypeScript-first React component for creating resizable split-pane layouts with horizontal and vertical splits. It supports controlled and uncontrolled modes, nested panes, keyboard accessibility, and touch input.

## Use cases
- add resizable sidebar and main content panes to a react app
- build an ide-like layout with editor and console panels
- create a draggable vertical split between header and content
- persist user-adjusted pane sizes across sessions
- build accessible resizable panels with keyboard support

## When to choose
- you need resizable panes in a React application with full TypeScript support
- accessibility and touch support are requirements
- you want a tiny (<5KB) dependency-free layout component

## When to avoid
- your project does not use React
- you need complex grid or dockable window layouts rather than simple splits
- you need framework-agnostic web components

## Facets
- artifact type: library
- maturity: active
- function: ui-components, state-management
- domain: frontend, web-development, accessibility
- platform: browser
- tags: react, split-pane, resizable-panes, layout, hooks, typescript, touch-support, web-server, nodejs
