Updates useFormState to allow a sync function to be passed as an action. A form action is almost always async, because it needs to talk to the server. But since we support client-side actions, too, there's no reason we can't allow sync actions, too. I originally chose not to allow them to keep the implementation simpler but it's not really that much more complicated because we already support this for actions passed to startTransition. So now it's consistent: anywhere an action is accepted, a sync client function is a valid input.
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);
},
// ...
});
}
