A Node.js native add-on that writes V8 heap snapshots to disk for later inspection in Chrome DevTools. Snapshots can be triggered programmatically or via a SIGUSR2 signal on Unix systems.

Use cases

• debug memory leaks in node.js apps
• capture v8 heap snapshot at runtime
• inspect node process memory usage in chrome devtools
• trigger heap dump via signal on production server
• find retained objects causing high memory

When to choose

• you need on-demand heap snapshots from a running Node.js process
• you want to analyze memory leaks with Chrome DevTools
• you need a signal-triggered dump without restarting the app

When to avoid

• you are on modern Node.js with built-in heap snapshot APIs (v8.getHeapSnapshot / inspector)
• you need continuous memory monitoring rather than point-in-time dumps
• your heap is very large and you cannot afford the 2x memory overhead or the synchronous hitch
