doesn't deploy with CRA2 ?

[panzerstadt]

create-react-app test-project
cd test-project
yarn add retoggle

then import retoggle somewhere in the app

yarn build
serve -s build

it return an error:

Uncaught TypeError: Super expression must either be null or a function, not undefined
    at index.js:6135
    at index.js:6134

these are the two lines i added to a new CRA2 template:

import React from "react";
import { Inspector } from "retoggle";
//...
return (...
<Inspector usePortal={true} />
)
//...

It supposes to work. Seems like something we need to look into.

At this point I'm not sure if create-react-app@2 is usable. I just tried creating a project with it, but it doesn't generate all the project files with the following error:

A template was not provided. This is likely because you're using an outdated version of create-react-app.

I did just try create-react-app@latest (3.4.1 currently), added retoggle and updated the App.js like this and it appeared to work just fine.

import React from 'react';
import { Inspector, useBooleanKnob } from 'retoggle';
import logo from './logo.svg';
import './App.css';

function App() {
  const [value] = useBooleanKnob('Show learn more', true);
  return (
    <div className="App">
      <header className="App-header">
        <img src={logo} className="App-logo" alt="logo" />
        <p>
          Edit <code>src/App.js</code> and save to reload.
        </p>
        {value && (
          <a
            className="App-link"
            href="https://reactjs.org"
            target="_blank"
            rel="noopener noreferrer"
          >
            Learn React
          </a>
        )}
      </header>
      <Inspector />
    </div>
  );
}

export default App;

@panzerstadt can you confirm if this is still an issue for you?
