This workflow is awaiting approval from a maintainer in #720

Can the CI be approved so that I can verify if its working on the ubuntu host as well? My dev box is Windows.

This is awesome - excellent work!

Since we have GitHub Actions now running smooth, do we want to disconnect CircleCI from this repo?
I still get emails on every commit if there is an active PR.

https://app.circleci.com/pipelines/github/vercel/serve

Let me know if an issue should be raised for the same?

[schemburkar]

Thanks @gamemaker1 For the feedback, address all your comments.

[leerob]

Okay, CircleCI should hopefully be removed now.

[schemburkar]

All checks are passing fine, do you have any other feedback for me on this PR? If not, I would say its ready to be merged.

[gamemaker1]

Looks good to me :]

[leerob]

Excellent work!
