react-draggable is a mature, well-maintained React library that provides two components for making elements draggable: `<Draggable>` (a high-level, state-managed component that applies CSS transforms) and `<DraggableCore>` (a low-level, stateless primitive that fires raw drag events). The library handles mouse and touch events, supports axis constraints, bounds (parent, selector, or numeric), grid snapping, scaling, and controlled/uncontrolled position modes. It uses CSS transforms for positioning, avoiding conflicts with CSS layout. The codebase was recently migrated from Flow to TypeScript (v4.6.0), ships CommonJS, ESM, and UMD builds, and includes a comprehensive test suite (unit tests in jsdom + browser tests via Puppeteer). The architecture is clean: `Draggable` wraps `DraggableCore`, adding state management and transform application, while utility modules (`domFns`, `positionFns`, `getPrefix`, `shims`) handle DOM operations, position calculations, browser prefix detection, and general helpers. The library is actively maintained with recent commits, a thorough CI pipeline, and detailed documentation including a CSP nonce feature and React 19 compatibility.
