To convert a Node.js `Readable` stream to an `ArrayBuffer` in Bun, you can create a new `Response` object with the stream as the body, then use `arrayBuffer()` to read the stream into an `ArrayBuffer`.

```ts
import { Readable } from "stream";
const stream = Readable.from(["Hello, ", "world!"]);
const buf = await new Response(stream).arrayBuffer();
```
