Hi,

I'm encountering an issue when attempting to render email templates using maily. Specifically, I get the following error:

TypeError: reactDOMServer.renderToPipeableStream is not a function

Here’s a screenshot:

Steps to Reproduce:

I'm just trying this on the frontend

const maily = new Maily({
		type: 'doc',
		content: [
		  {
			type: 'repeat',
			attrs: { each: 'items', showIfKey: null },
			content: [
			  {
				type: 'paragraph',
				attrs: { textAlign: 'left' },
				content: [{ type: 'text', text: 'Hello' }],
			  },
			],
		  },
		],
	  });
 const html = await maily.render();
 console.log("HTML", html);

I also tried this on the backend. I have the json stored in the db, I tried to send out emails using json, converting it to HTML. Similar error occurs.

Environment:
@maily-to/core version: ^0.2.7
@maily-to/render version: "^0.1.3",

React version: 19.1.0

Can someone help me with this issue please?

You should be using it in backend not in frontend.
