Adds back the `TestUtils.act` implementation that I had removed in #19745. This version of `act` is implemented in "userspace" (i.e. not the reconciler), so it doesn't add to the production bundle size. I had removed this in #19745 in favor of the `act` exported by the reconciler because I thought we would remove support for `act` in production in the impending major release. (It currently warns.) However, we've since decided to continue supporting `act` in prod for now, so that it doesn't block people from upgrading to v17. We'll drop support in a future major release. So, to avoid bloating the production bundle size, we need to move the public version of `act` back to "userspace", like it was before. This doesn't negate the main goal of #19745, though, which was to decouple the public version(s) of `act` from the internal one that we use to test React itself.
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 />);
