Sebastian Markbåge 3fbfb9baaf Emit Activity boundaries as comments in Fizz (#32834)
Uses `&` for Activity as opposed to `$` for Suspense. This will be used
to delimitate which nodes we can skip hydrating.

This isn't used on the client yet. It's just a noop on the client
because it's just an unknown comment. This just adds the SSR parts.

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.
