# Inspect memory usage using V8 heap snapshots
Bun implements V8's heap snapshot API. Use it to capture the heap at runtime and debug memory leaks in your JavaScript/TypeScript application.
```ts snapshot.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-153748d0-sqlite-bind-column-cache-fixes/YdClCW0JYijHyS9h/icons/typescript.svg?fit=max&auto=format&n=YdClCW0JYijHyS9h&q=85&s=3d263a69b234b707ede6efa6aab5adf5" theme={"theme":{"light":"github-light","dark":"dracula"}}
import v8 from "node:v8";
// Creates a heap snapshot file with an auto-generated name
const snapshotPath = v8.writeHeapSnapshot();
console.log(`Heap snapshot written to: ${snapshotPath}`);
```
