"I don't see this mentioned, but is KV.js used somewhere in production? "

Hey, author here. It's used in puter.com, my startup. Still in alpha though.

"For example in a separate worker, in a child process or in the same process as the node.js app," Right now I'd say in the same process as the node.js app. Open to suggestions.

"Side note, is lua support in consideration?" Yes.

"the author did a great job!"

Thank you! Please do let me know how I could make it better :)
