+Exports new `createRequest()` and `writeResponse()` utilities from `astro/app/node`
+
+To replace the deprecated `NodeApp.createRequest()` and `NodeApp.writeResponse()` methods, the `astro/app/node` module now exposes new `createRequest()` and `writeResponse()` utilities. These can be used to convert a NodeJS `IncomingMessage` into a web-standard `Request` and stream a web-standard `Response` into a NodeJS `ServerResponse`:
+
+```js
+import { createApp } from 'astro/app/entrypoint';
+import { createRequest, writeResponse } from 'astro/app/node';
+import { createServer } from 'node:http';
+
+const app = createApp();
+
+const server = createServer(async (req, res) => {
+    const request = createRequest(req);
+    const response = await app.render(request);
+    await writeResponse(response, res);
+})
+```
