The Node.js Memory Leak Traffic: How to Find and Fix It

Описание: Is your Node.js app's memory usage steadily creeping up until it freezes or crashes? You're fighting a Memory Leak! Forget staring at confusing docs—we use a simple, memorable High-End Restaurant Kitchen analogy to explain exactly why leaks happen and how to eliminate them.

The problem isn't the code; it's the forgotten references (the "dirty plates left on the shelf"). This video gives you the tools and the process to become a leak-hunting detective.

Here’s the Memory Leak Detective Playbook (with timestamps):

The Kitchen Analogy: Understanding the staff (Code/Functions), the equipment (Memory/Plates), and the unsung hero (The V8 Garbage Collector) [00:48].

The Real Villain: The "Forgotten Shelves" (Global Variables, Caches, Listeners) that block the Garbage Collector [02:49].

The 3 Common Culprits:

The Sticky Note Wall: Event Emitter Listener Leaks [03:45].

Unbounded Storage: Global Arrays and Maps with No Size Limit [04:09].

The Runaway Conveyor Belt: Forgotten setInterval calls [04:33].

The 4-Step Playbook to Hunt Leaks: Monitor, Reproduce, Snapshot, and Compare memory heaps [05:20].

The Fix: Swapping out leaky patterns with safe, bounded solutions like LRU Caches [05:57].
