proper es module

[felixroos]

It would be great if this could be packaged as a proper es module. I could not use this package with snowpack, also, it won't work with skypack. For example, the following html:

<script type="module">
  import { parseScriptWithLocation } from 'https://cdn.skypack.dev/shift-parser';
</script>

will produce the following error

shift-parser.js:4857 Uncaught TypeError: Super expression must either be null or a function, not undefined
    at _inherits (shift-parser.js:4857:13)
    at shift-parser.js:4931:5
    at shift-parser.js:5690:4
    at createCommonjsModule (shift-parser.js:15:6)
    at shift-parser.js:4785:19

Generally, I wonder if shift is still maintained?

It is still maintained, though I'm behind at the moment.

I'll think about publishing an ES module. The state of ESM was kind of chaotic last I checked but there's probably a reasonable solution.

that would be great! I could also try it myself and send a PR if you want
