Named import in typescript

[martinsura]

Hi,

First - nice idea. I have question

Its possible use svelte-draft and typescript with no default exports?

For example:

App.tsx

import {Component} from "./Component";

export default function App(){
   <Component />
   ...
}

Component.tsx

export const Component = () => {
<h1>Hello world</h1>
}

Now i got error:

Module build failed (from ./node_modules/svelte-draft-loader/src/index.js):
TypeError: Cannot read property 'get' of undefined

No, a default export must be specified because "the default export is the component itself", which is the convention of svelte, see https://svelte.dev/docs#script_context_module.
