In Bun, Response objects can accept a Node.js Readable. 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.

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'},
		});
	},
});
