Sebastian Markbåge 7a3cb8f9cf Track the key path difference between right before the first array (#27360)
There's a subtle difference if you suspend before the first array or
after. In Fiber, we don't deal with this because we just suspend the
parent and replay it if lazy() or Usable are used in its child slots. In
Fizz we try to optimize this a bit more and enable resuming inside the
component.

Semantically, it's different if you suspend/postpone before the first
child array or inside that child array. Because when you resume the
inner result might be another array and either that's part of the parent
path or part of the inner slot.

There might be more clever way of structuring this but I just use -1 to
indicate that we're not yet inside the array and is in the root child
position. If that renders an element, then that's just the same as the 0
slot.

We need to also encode this in the resuming. I called that resuming the
element or resuming the slot.

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);
    },
    // ...
  });
}
