This is a CMS & API written in Go. I've never written such a system before, so Go has wonderful opportunity – this ecosystem encourages usage of small libraries, not big frameworks.
So far I have next ecosystem:
- gin framework for routing and static serving
- sql driver
- imgio for image processing
For the client-side (js and styles) I have a gulp (due to large ecosystem and absence of babel). Sass for the styles, and plain ES5 javascipt. The latter is kind of boring, but babel is too big nowadays, and until I have bunch of modules to share, I don't really want to introduce it here. For any other language, it won't work, because it is all about 3rd-party libraries, so best interoperability is must, and nothing has it (except coffeescript, but who cares nowadays about it).
