To convert a [`ReadableStream`](https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream) to a `Buffer`, read its contents into an [`ArrayBuffer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) with `Bun.readableStreamToArrayBuffer`, then create a [`Buffer`](https://nodejs.org/api/buffer.html) that points to it.
|
|
|
|
```ts
|
|
const stream = new ReadableStream();
|
|
const arrBuf = await Bun.readableStreamToArrayBuffer(stream);
|
|
const nodeBuf = Buffer.from(arrBuf);
|
|
```
