To convert a Node.js `Readable` stream to an `Uint8Array` in Bun, you can create a new `Response` object with the stream as the body, then use `bytes()` to read the stream into an `Uint8Array`.
```ts
import { Readable } from "stream";
const stream = Readable.from(["Hello, ", "world!"]);
const buf = await new Response(stream).bytes();
```
