@kdorosh thanks!
wow it seems that a lot of stuff is added to the node_modules folder, are you sure that this is all necessary?
I'm not super expert with TS, but it seems that when pulling your PR a very big amount of stuff is downloaded, maybe also dev-dependencies were downloaded during your update?

Switched to branch 'update_with_upstream'

I just ran npm install, it does seem like a lot. Perhaps I did snag dev dependencies as well. Not sure all of it is necessary.

I see @kdorosh, may I ask you to test again in your CI the current master branch?

I did an upgrade and a bit of dev dependencies cleanups.

In the meantime, I'm setting up a test env, but maybe you are quicker than me, I lost a bit of my grip on Github Actions 😸

current arduino master works with our ci, tested in solo-io/gloo#3875 (the passing check https://github.com/solo-io/gloo/pull/3875/checks?check_run_id=1408161055)

closing this PR since #16 handles it more cleanly

thanks @rsora !

Thanks @kdorosh for your support, this nice interaction reminded me why I signed to be an OSS maintainer for Arduino 👍

I'm preparing a tag and a release for the Action in the next minutes, keep your eyes peeled 😸
