Grokking Asynchronous Work in Node.js
summary
Claims that the Async Hooks API gives concrete, low‑overhead visibility into Node.js asynchronous lifecycles and demonstrates the init before after destroy events and asyncId/triggerAsyncId semantics; shows practical code using process_raw_debug and a low‑level hook plus higher‑level file system and network collectors, processors and a simple visualizer; measures that hooks add minimal cost when idle and that the collector/processor pipeline successfully reconstructs operations (reads, opens, requests) for diagnosis.
