`cls-hooked` provides continuation‑local storage for Node.js, letting you attach data to the logical flow of asynchronous callbacks (like thread‑local storage). It works on Node < 8 via the undocumented **AsyncWrap** API and on Node ≥ 8.2.1 via the experimental **async_hooks** API, making it useful for server‑side code (e.g., Express middleware) that needs to share request‑scoped state without polluting objects. It’s aimed at Node developers who need safe, per‑request context across async operations.
