+## New React DOM Static APIs {/*new-react-dom-static-apis*/}
+
+We've added two new APIs to `react-dom/static` for static site generation:
+- [`prerender`](/reference/react-dom/static/prerender)
+- [`prerenderToNodeStream`](/reference/react-dom/static/prerenderToNodeStream)
+
+These new APIs improve on `renderToString` by waiting for data to load for static HTML generation. They are designed to work with streaming environments like Node.js Streams and Web Streams. For example, in a Web Stream environment, you can prerender a React tree to static HTML with `prerender`: 
+
+```js
+import { prerender } from 'react-dom/static';
+
+async function handler(request) {
+  const {prelude} = await prerender(<App />, {
+    bootstrapScripts: ['/main.js']
+  });
+  return new Response(prelude, {
+    headers: { 'content-type': 'text/html' },
+  });
+}
+```
+
+Prerender APIs will wait for all data to load before returning the static HTML stream. Streams can be converted to strings, or sent with a streaming response. They do not support streaming content as it loads, which is supported by the existing [React DOM server rendering APIs](/reference/react-dom/server).
