Use Svelte components inside React apps.
import { render } from 'react-dom';
import SvelteComponent from 'react-svelte';
import Widget from './Widget.html';
function MyReactApp(props) {
	return (
		<div>
			<p>this is a Svelte component inside a React app:</p>
			<SvelteComponent this={Widget} {...props}/>
		</div>
	)
}
render(<MyReactApp/>, document.querySelector('main'));Demo here, source code for the demo here.
Because React's support for custom elements is somewhat lacking.
This is a fairly basic integration, some things don't currently work and possibly never will:
- the value of 
thisis fixed; changing it after the initial render will have no effect - you can't use 
<slot>
