Currently React attempts to prioritize certain preloads over others based on their type. This is at odds with allowing the user to control priority by ordering which calls are made first. There are some asset types that generally should just be prioritized first such as fonts since we don't know when fonts will be used and they either block display or may lead to fallback fonts being used. But for scripts and stylesheets we can emit them in the order received with other arbitrary preload types. We will eventually add support for emitting suspensey image preloads before other resources because these also block display however that implementation will look at which images are actually rendered rather than simply preloaded.
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);
},
// ...
});
}
