Looks good to me. I tried the updated example locally, it worked fine.

Just one glitch - not sure if you care about it. When running the dev script for the very first time, serve:luigi and serve:microfrontend exit with this:

[1] npm run serve:luigi exited with code 1
[2] The system cannot find the path specified.
[2] npm run serve:microfrontend exited with code 1

When running dev a second time, everything works.

From what I could see, the problem is that serve:luigi and serve:microfrontend start before build:dev is finished and they cannot handle the public folder not being there yet. You can simulate this by deleting the public folder and then running dev again.

@camelCaseChris Good point. Adjusted as necessary.
