We disallow empty strings for `href` and `src` since they're common mistakes that end up loading the current page as a preload, image or link. We also disallow it for `action`. You have to pass `null` which is the same. However, for `formAction` passing `null` is not the same as passing empty string. Passing empty string overrides the form's action to be the current page even if the form's action was set to something else. There's no easy way to express the same thing `#` show up in the user visible URLs and `?` clears the search params. Since this is also not a common mistake, we can just allow this.
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);
},
// ...
});
}
