Node Memory Profiler

A guide to finding and fixing memory leaks in Node.js applications using profiling tools and heap analysis.

Usage

Ask about memory profiling, heap snapshots, leak detection, or memory optimization.

Examples

• "Take and compare heap snapshots to find a memory leak"
• "How do I use clinic.js to profile memory usage?"
• "Fix a memory leak caused by event listeners"

Guidelines

• Take heap snapshots before and after the suspected leak operation
• Look for growing object counts in snapshot comparisons
• Remove event listeners when they are no longer needed
• Avoid storing large data in module-level closures
• Use WeakMap and WeakRef for caches that should be garbage collected
