SyntaxError while importing react-dom / react

[p-sw]

Describe the bug
It throws SyntaxError everytime I load localhost:5314.

file:///home/shinwoo-park/WebstormProjects/ui-docs/dist/rsc/App.js:5
import ReactDOM, { createPortal } from 'react-dom';
                   ^^^^^^^^^^^^
SyntaxError: Named export 'createPortal' not found. The requested module 'react-dom' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'react-dom';
const { createPortal } = pkg;

@p-sw Thank you for reporting! I reproduced the same issue, and I will immediately work on it.

@p-sw It looks like you are trying to use createPortal in server components.

Will you try this instead?

'use client'

import { createPortal } from "react-dom";

export default function App() {
  return typeof document !== "undefined" ? createPortal(<div>Hello</div>, document.body) : null
}

Ah, one more. You need to add tsconfig.json at the root containing this line:

{
	"compilerOptions": {
		"jsx": "react-jsx"
	}
}

This is required since you manually setup your project with mkdir, and Vite's default JSX transform rule is react. I will make seia to use react-jsx by default later!
