+
+In Bun, [`Response`](https://developer.mozilla.org/en-US/docs/Web/API/Response) objects can accept a Node.js [`Readable`](https://nodejs.org/api/stream.html#stream_readable_streams).
+
+This works because Bun's `Response` object allows any async iterable as its body. Node.js streams are async iterables, so you can pass them directly to `Response`.
+
+```ts
+import { Readable } from "stream";
+import { serve } from "bun";
+serve({
+  port: 3000,
+  fetch(req) {
+    return new Response(Readable.from(["Hello, ", "world!"]), {
+      headers: { "Content-Type": "text/plain" },
+    });
+  },
+});
+```

+
+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();
