When a lazy element or component is initialized a thenable is returned which was only be conditionally instrumented in dev when asyncDebugInfo was enabled. When instrumented these thenables can be used in conjunction with the SuspendOnImmediate optimization where if a thenable resolves before the stack unwinds we can continue rendering from the last suspended fiber. Without this change a recent fix to the useId implementation cannot be easily tested in production because this optimization pathway isn't available to regular React.lazy thenables. To land the prior PR I changed the thenables to a custom type so I could instrument manually in the test. WIth this change we can just use a regular Promise since ReactLazy will instrument in all environments/flags now
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);
},
// ...
});
}
