When an `identifierPrefix` option is given, React will add it to the beginning of ids generated by `useId`. The main use case is to avoid conflicts when there are multiple React roots on a single page. The server API already supported an `identifierPrefix` option. It's not only used by `useId`, but also for React-generated ids that are used to stitch together chunks of HTML, among other things. I added a corresponding option to the client. You must pass the same prefix option to both the server and client. Eventually we may make this automatic by sending the prefix from the server as part of the HTML stream.
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
var React = require('react');
var ReactDOM = require('react-dom');
function MyComponent() {
return <div>Hello World</div>;
}
ReactDOM.render(<MyComponent />, node);
On the server
var React = require('react');
var ReactDOMServer = require('react-dom/server');
function MyComponent() {
return <div>Hello World</div>;
}
ReactDOMServer.renderToString(<MyComponent />);
