# Convert a Node.js Readable to an ArrayBuffer

> Read a Node.js `Readable` stream into an `ArrayBuffer` by wrapping it in a `Response` and calling `.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
import { Readable } from "stream";
const stream = Readable.from(["Hello, ", "world!"]);
const buf = await new Response(stream).arrayBuffer();
```
