Because we now decided whether to outline in the flushing phase, when we're writing the preamble we don't yet know if we will make that decision so we don't know if it's safe to omit the external runtime. However, if you are providing an external runtime it's probably a pretty safe bet you're streaming something dynamically that's likely to need it so we can always include it. The main thing is that this makes it hard to test it because it affects our tests in ways it wouldn't otherwise so we have to add a bunch of conditions.
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);
},
// ...
});
}
