How to render component packed in bundle with pure javascript?

I create simple app with create-react-app and i call ‘npm run build’ in the terminal. webpack creates a bundle file and i am trying to use this bundle file in my regular JavaScript app.bu i get ‘reference not found’ error for my component like “SetBuilder is not defined”.

this is what i am trying :

in create react-app index file:

import SetBuilder from './SetBuilder';

export {
    SetBuilder 
}

in my javascript file:

ReactDOM.render(ReactDOM.createElement(SetBuilder),document.getElementById("root"));

but i get preceding error.what am i doing wrong? here is the relevant question in StackOverflow.

Yes, you just remove react-scripts from your package.json and add create-react-library.
