Full-Link Tracing in Node.js Applications: Async Hooks and Zone-Context Design

The article details a full‑link tracing system for Node.js that leverages experimental async_hooks to monitor asynchronous resource lifecycles, builds an invoke‑tree to map parent‑child relationships, implements garbage collection, and provides a ZoneContext API for propagating custom tracing data across async call chains.
