heap-snapshot-analysis

You can find memory leaks in V8 heap snapshots by parsing large `.heapsnapshot` files and diffing before-and-after captures to identify object groups that grew in size or count after a change.

Objects survive garbage collection because non-weak retainer paths keep them alive. Tracing these references back to GC roots reveals the specific closures and caches preventing collection.

Compare two heap snapshots by diffing node counts and self sizes between before-and-after captures. This identifies which constructor groups grew and pinpoints the classes responsible for retained memory.

Yes, you can analyze disposed instances, cache buildup, and closure retention in VS Code-based applications by loading V8 heap snapshots and tracing non-weak retainer paths back to GC roots.

The best way to trace retainer paths is to follow non-weak references back to GC roots from retained objects. This reveals exactly which objects and closures are preventing garbage collection.

Yes, heap snapshot analysis works with large `.heapsnapshot` files by extracting nodes, edges, strings, and metadata for constructor grouping and comparison of node counts and self sizes.
