warning

▲ [WARNING] Top-level "this" will be replaced with undefined since this file is an ECMAScript module

    src/server/controller/HomeController.ts:1:18:

        ╵                   undefined

  This file is considered to be an ECMAScript module because of the "export" keyword here:

This is likely a esbuild issue.

The code you put up above is the build command. I don't have time in the next week or so to look into this. You might try the esbuild CLI as a starting point. You'll have to set up your own config, but that is where I'd look.

There is a chance that esbuild needs more options set or this plugin could use more options added. Feel free to put in a pull request.
