# Convert a Node.js Readable to an ArrayBuffer

To convert a Node.js `Readable` stream to an `ArrayBuffer` in Bun, create a `Response` with the stream as the body, then call `arrayBuffer()`.

```ts theme={"theme":{"light":"github-light","dark":"dracula"}}
import { Readable } from "stream";
const stream = Readable.from(["Hello, ", "world!"]);
const buf = await new Response(stream).arrayBuffer();
```
