Q: ReactDOMServer renderToNodeStream()

1 Answer

Render a React element to its initial HTML. Returns a Readable stream that outputs an HTML string. The HTML output by this stream is exactly equal to what ReactDOMServer.renderToString would return. You can use this method to generate HTML on the server and send the markup down on the initial request for faster page loads and to allow search engines to crawl your pages for SEO purposes.

If you call ReactDOM.hydrate() on a node that already has this server-rendered markup, React will preserve it and only attach event handlers, allowing you to have a very performant first-load experience.

Note:

Server-only. This API is not available in the browser.

The stream returned from this method will return a byte stream encoded in utf-8. If you need a stream in another encoding, take a look at a project like iconv-lite, which provides transform streams for transcoding text.
