The `enableCustomElementPropertySupport` flag changes React's handling of custom elements in a way that is more useful that just treating every prop as an attribute. However when server rendering we have no choice but to serialize props as attributes. When this flag is on and React supports more prop types on the client like functions and objects the server implementation needs to be a bit more naunced in how it renders these components. With this flag on `false`, function, and object props are omitted entirely and `true` is normalized to `""`. There was a bug however in the implementation which caused children more complex than a single string to be omitted because it matched the object type filter. This change reorganizes the code a bit to put these filters in the default prop handline case, leaving children, style, and innerHTML to be handled via normal logic. fixes: https://github.com/facebook/react/issues/27286
react-dom
This package serves as the entry point to the DOM and server renderers for React. It is intended to be paired with the generic React package, which is shipped as react to npm.
Installation
npm install react react-dom
Usage
In the browser
import { createRoot } from 'react-dom/client';
function App() {
return <div>Hello World</div>;
}
const root = createRoot(document.getElementById('root'));
root.render(<App />);
On the server
import { renderToPipeableStream } from 'react-dom/server';
function App() {
return <div>Hello World</div>;
}
function handleRequest(res) {
// ... in your server handler ...
const stream = renderToPipeableStream(<App />, {
onShellReady() {
res.statusCode = 200;
res.setHeader('Content-type', 'text/html');
stream.pipe(res);
},
// ...
});
}
