Zero-Boilerplate Request ID Tracing in Node.js with pino-correlation-id

Zero-Boilerplate Request ID Tracing in Node.js with pino-correlation-id You get a bug report. A user hit an error at 2:14 AM. You open your logs and see hundreds of concurrent requests all jumbled together — no way to tell which log lines belong to which request. You're flying blind. Correlation IDs solve this. Every request gets a unique ID. Every log line — no matter how deep in the call stack — carries that ID. You can filter to a single request in seconds. The problem? Passing a correlationId parameter through every function call is boilerplate hell. Change a service interface and you touch 20 files. AsyncLocalStorage eliminates that entirely. This is the exact problem pino-correlation-id was built to solve. npm install pino-correlation-id The Problem: Async Logs Have No Thread In threaded languages (Java, C#), you'd use thread-local storage to attach a request ID to the current thread. Every log call on that thread automatically includes the ID. Node.js is single-threaded with an
