@loynoir Did you try to replace the line export default class MagicString { by export = class MagicString { ?

With commonjs, the current behavior maps the MagicString class to module.exports.default. Using export = instead of export default will map the MagicString class to module.exports.

You'll find a more detailed explanation of the export = syntax here.
