Janka Uryga b1533b034e [Flight] Allow overriding request.timeOrigin via options.startTime (#35598 )

Currently, IO that finished before the request started is not considered
IO:

6a0ab4d2dd/packages/react-server/src/ReactFlightServer.js (L5338-L5343)
This leads to loss of debug info when a flight stream is deserialized
and serialized again.
We can solve this by allowing "when the the request started" to be set
to a point in the past, when the original stream started by doing

```js
const startTime = performance.now() + performance.timeOrigin
// ... stuff happens and time passes...
ReactServer.renderToReadableStream(..., { startTime })
```

README.md

`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.

The React team thanks Nikolai Mavrenkov for donating the react-markup package name.
