I'm going to approve this extension, since I don't see anything excessively dangerous or malicious, but it would nice if you could clean up the generated code in future so it can be reviewed more easily.

Thank you for your advice. I have updated the code as you suggested. But I will not submit a new version yet. I will look into rollup like you said. then, I will submit it.

Okay, another developer pointed me to an extension here which uses typescript and rollup, maybe it will be helpful: https://github.com/rockon999/simple-dock
