Josh Story 8de7aed892 [Fizz] Count Boundary bytes that may contribute to the preamble in the request byteSize (#34059)
Stacked on #34058

When tracking how large the shell is we currently only track the bytes
of everything above Suspense boundaries. However since Boundaries that
contribute to the preamble will always be inlined when the shell flushes
they should also be considered as part of the request byteSize since
they always flush alongside the shell. This change adds this tracking

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