Using free and open source Haskell and with minimal or ideally no external libraries, I need to build a very simple RESTful-API/database server and a CLI to manage it. I need to use it for serving up webpages, text files, or selected lines of json from a text file. After this is done, I would like to give it a GUI. My problem is I can't find any tutorials that explain how to do any of this.
Does anyone know of any tutorials that fit these requirements?
Much thanks
