react-dock

Resizable dockable React component that allows creating draggable side panels for layouts. Current stable version is 0.8.0, with infrequent releases. Supports React 16.3+ through 19. Ships TypeScript types. Unlike generic resizable panels, react-dock is purpose-built for docking to edges and dimming overlay modes (opaque, transparent, none). Ideal for sidebars, devtools, or notification panels. Peer dependencies: @types/react and react. Old but stable; no known breaking changes in recent history.
