This is in line with the refactor I already did on Fizz earlier and brings Fiber up to a similar structure. We end up with a lot of extra checks due the extra abstractions we use to check the various properties. This uses a flatter and more inline model which makes it easier to see what each property does. The tradeoff is that a change might need changes in more places. The general structure is that there's a switch for tag first, then a switch for each attribute special case, then a switch for the value. So it's easy to follow where each scenario will end up and there shouldn't be any unnecessary code executed along the way. My goal is to eventually get rid of the meta-programming in DOMProperty and CSSProperty but I'm leaving that in for now - in line with Fizz. My next step is moving around things a bit in the diff/commit phases. This is the first step to more refactors for perf and size, but also because I'm adding more special cases so I need to have a flatter structure that I can reason about for those special cases.
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);
},
// ...
});
}
