Couple things that stood out: code is not in a "src" folder separate from configuration. Views have just an "html" file extension - usually you would at least have the templating language extension there too. Didn't see any indication of test coverage. Also it looks like you have your own test runner?? Using Jest for ex. gives you a lot.

First thing in the readme is lines of code. I would start with what this is, what problems it solves, and why it's better than the alternatives.
