I have a JS class that I'd like to build in to a library with Webpack.

class MyCoolComponent {

  constructor(a, b, c) {
  }

  render() {
    // Do stuff
  }

}

export default MyCoolComponent;

The ultimate goal is to have end users source my script (with a <script> tag) and have the MyCoolComponent variable exposed as a variable globally in their browser.

According to the Webpack docs, I can expose the variable by configuring library and libraryTarget in my Webpack config file:

output: {
  // ...
  library: 'MyCoolComponent',
  libraryTarget: 'var',
  // ...
},

When I bundled the script, sourced it on the page, and tried accessing MyCoolComponent in my browser console, I received the following error:

var mcc = new MyCoolComponent('a', 'b', 'c');
=> TypeError: MyCoolComponent is not a constructor

I noticed that MyCoolComponent is actually an object with a default key, and it works if I access that key directly:

var mcc = new MyCoolComponent.default('a', 'b', 'c');
=> (No Error)

1. Why does this occur? I specified export default MyCoolComponent in the JS file, so shouldn't the class be the default thing exported?

2. How can I configure the export so that I don't have to access it with .default()?

Thanks!
