## Summary This PR bumps Flow all the way to the latest 0.245.2. Most of the suppressions comes from Flow v0.239.0's change to include undefined in the return of `Array.pop`. I also enabled `react.custom_jsx_typing=true` and added custom jsx typing to match the old behavior that `React.createElement` is effectively any typed. This is necessary since various builtin components like `React.Fragment` is actually symbol in the React repo instead of `React.AbstractComponent<...>`. It can be made more accurate by customizing the `React$CustomJSXFactory` type, but I will leave it to the React team to decide. ## How did you test this change? `yarn flow` for all the renderers
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);
},
// ...
});
}
