The **async‑task‑mgr** package provides a tiny Node.js library that coordinates asynchronous operations by task name. When multiple callers add a task with the same identifier, the library runs the underlying action only once, caches its result, and delivers that result to all queued callbacks, making it ideal for developers who need to avoid duplicate work (e.g., repeated API calls, expensive calculations) while sharing the outcome across different parts of an application.
