There are ways to do this configuring webpack (ex: https://stackoverflow.com/a/34361312/2043830) but I was unable to make it work.

So instead I use the global window object to store the things that I want to expose to index.html.

For example, in your index.js you could do:

window.exported = {one, two, three};
//or window.one = one; window.two = two ... etc

Then in your index.html:

<script>
let oneObj = new window.exported.one();
//or let oneObj = new window.one(); ... etc
</script>

I hope this helps.

This is not an intended use case and therefore requires special handling using expose-loader.

The idea of a module bundler is to run all JavaScript through it (other than having some code somewhere outside). So when you code with export {one, two, three} is in lib.js, use it in app.js:

import {one} from './lib.js';
let oneObj = new one();

Configure webpack to use ./app.js as entry file, and finally remove the inline script from your index.html.
