Looking to get critique on an web app

Hello,

Wrote a web application. Looking for critique. Any critique is welcome, bad practices etc. Mainly want to point people who ask questions relevant to this straight to it so they can look it up. I will update the project based on community feedback.

I also intend to use this as a base for future projects. Have I structured the project well for large scale applications.

In apis/api.go I wrote a wrapper function withACAO(someInput) to handle access control allow origin. Good idea, Bad Idea?

Thanks in advance!
