For the `useId` algorithm we used colon `:` before and after. https://github.com/facebook/react/pull/23360 This avoids collisions in general by using an unusual characters. It also avoids collisions when concatenated with some other ID. Unfortunately, `:` is not a valid character in `view-transition-name`. This PR swaps the format from: ``` :r123: ``` To the unicode: ``` «r123» ``` Which is valid CSS selectors. This also allows them being used for `querySelector()` which we didn't really find a legit use for but seems ok-ish. That way you can get a view-transition-name that you can manually reference. E.g. to generate styles: ```js const id = useId(); return <> <style>{` ::view-transition-group(${id}) { ... } ::view-transition-old(${id}) { ... } ::view-transition-new(${id}) { ... } `}</style> <ViewTransition name={id}>...</ViewTransition> </>; ```
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);
},
// ...
});
}
