Currently when we SSR a Flight response we do not emit any resources for module imports. This means that when the client hydrates it won't have already loaded the necessary scripts to satisfy the Imports defined in the Flight payload which will lead to a delay in hydration completing. This change updates `react-server-dom-webpack` and `react-server-dom-esm` to emit async script tags in the head when we encounter a modules in the flight response. To support this we need some additional server configuration. We need to know the path prefix for chunk loading and whether the chunks will load with CORS or not (and if so with what configuration).
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);
},
// ...
});
}
