This repo is a minimal reproduction of a bug in Parcel v2.10.3.

1. Clone this repo
2. Run npm install using Node.js v18+
3. Run npm start
4. Open https://localhost:8080 in your browser
5. Open the browser's console

You should see the following error:

Uncaught SyntaxError: The requested module './dist/my-counter.js' does not provide an export named 'MyCounter'

There should be a named export MyCounter in the generated file dist/my-counter.js so that it can be imported like this:

import { MyCounter } from './dist/my-counter.js';

In the generated file dist/my-counter.js there is no export statement for the MyCounter class. On the other hand, in the dist/my-counter-defined.js file there is a named export for the MyCounter class.
