Express app, multiple issues

[brianjenkins94]

Hi, I'm running into multiple issues with Nodebox trying to run a fairly standard Express app.

Here's my sandbox: https://codesandbox.io/p/sandbox/nodebox-issue-vty6zs

Here are my issues:

// 1.
// These appear to break the Nodebox:
const __filename = url.fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

// 2.
// Despite setting this header, the browser console shows the error:
// > Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "application/octet-stream". Strict MIME type checking is enforced for module scripts per HTML spec.
response.setHeader("Content-Type", "text/javascript");

// 3.
// response.sendFile() would not work.
//response.sendFile(path.join(__dirname, "public", "js", "main.js"));
// I had to do this as a workaround:
response.send(await fs.readFile("public/js/main.js"));

I think 2 may be related to #39
