We unnecessarily render the preamble in a task. This updates the implementation to perform this render inline. Testing this is tricky because one of the only ways you could assert this was even happening is based on how things error if you abort while rendering the root. While adding a test for this I discovered that not all abortable tasks report errors when aborted during a normal render. I've asserted the current behavior and will address the other issue at another time and updated the assertion later as necessary
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);
},
// ...
});
}
