What tools does this skill recommend for analysis?

It guides you through using Chrome DevTools (Memory tab) for snapshot comparison and Clinic.js for automated heap profiling.

How do I reduce GC pressure?

The skill suggests monitoring GC via performance hooks and reducing allocation churn through object pooling or increasing heap limits via Node flags.

Can this skill help with production memory issues?

Yes, it includes methods to trigger heap snapshots in production using SIGUSR2 signals or secure admin endpoints without restarting the process.

How do I confirm if my Node.js app has a memory leak?

The skill provides a monitoring script to track heapUsed and RSS over time. A leak is confirmed if memory grows monotonically and never stabilizes, even after traffic ceases.

Does it cover EventEmitter leaks?

Yes, it specifically addresses the common pattern where listeners are added but never removed, leading to growing reference chains.

分析与监控

Diagnoses and resolves memory leaks, heap snapshot issues, and garbage collection pressure in Node.js applications.

The memory-debug skill provides specialized guidance for identifying and fixing memory-related performance issues in Node.js services. It offers a structured methodology to distinguish between normal memory usage and actual leaks, providing step-by-step instructions for capturing and analyzing V8 heap snapshots. By documenting common retention patterns like EventEmitter leaks, unbounded caches, and closure-related memory bloat, it helps developers stabilize long-running backend processes and prevent OOM (Out of Memory) crashes.
