async‑chainable is a Node.js library that extends the classic **async** module with a chainable, object‑oriented API for mixing series and parallel operations, flow‑control helpers (limit, await, prereq, hooks, timeout, etc.), and a built‑in context object. It’s aimed at developers who need to orchestrate complex asynchronous pipelines—especially in server‑side code or Express apps—while keeping the code readable and portable from existing async‑style projects.
