Reading or writing a ref value during render is only safe if you are implementing the lazy initialization pattern. Other types of reading are unsafe as the ref is a mutable source. Other types of writing are unsafe as they are effectively side effects. This change also refactors useTransition to no longer use a ref hook, but instead manage its own (stable) hook state.
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');
class MyComponent extends React.Component {
render() {
return <div>Hello World</div>;
}
}
ReactDOM.render(<MyComponent />, node);
On the server
var React = require('react');
var ReactDOMServer = require('react-dom/server');
class MyComponent extends React.Component {
render() {
return <div>Hello World</div>;
}
}
ReactDOMServer.renderToString(<MyComponent />);
