Hendrik Liebau f8e63c6645 [Flight] Preserve leading U+FEFF in text rows (#37625)
The Flight client dropped a leading `U+FEFF` from outlined text rows
when it decoded binary input. `TextDecoder` consumed the character as an
encoding signature, even though it was part of the serialized string.
Both the Node and Web decoders now use `ignoreBOM: true` to preserve it.

Regression tests cover one and two leading U+FEFF characters with normal
chunks and with every UTF-8 byte delivered separately. They also include
an inline-string control. The global `TextDecoder` Flow declaration now
makes `fatal` optional and declares `ignoreBOM`, matching the API.

react-markup

This package provides the ability to render standalone HTML from Server Components for use in embedded contexts such as e-mails and RSS/Atom feeds. It cannot use Client Components and does not hydrate. It is intended to be paired with the generic React package, which is shipped as react to npm.

Installation

npm install react react-markup

Usage

import { experimental_renderToHTML as renderToHTML } from 'react-markup';
import EmailTemplate from './my-email-template-component.js'

async function action(email, name) {
  "use server";
  // ... in your server, e.g. a Server Action...
  const htmlString = await renderToHTML(<EmailTemplate name={name} />);
  // ... send e-mail using some e-mail provider
  await sendEmail({ to: email, contentType: 'text/html', body: htmlString });
}

Note that this is an async function that needs to be awaited - unlike the legacy renderToString in react-dom.
