Based on - #29694 --- If an action in the useActionState queue errors, we shouldn't run any subsequent actions. The contract of useActionState is that the actions run in sequence, and that one action can assume that all previous actions have completed successfully. For example, in a shopping cart UI, you might dispatch an "Add to cart" action followed by a "Checkout" action. If the "Add to cart" action errors, the "Checkout" action should not run. An implication of this change is that once useActionState falls into an error state, the only way to recover is to reset the component tree, i.e. by unmounting and remounting. The way to customize the error handling behavior is to wrap the action body in a try/catch.
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);
},
// ...
});
}
