reflex-dom-inbits - A beginner friendly step by step tutorial for reflex-dom

This is a beginner-friendly tutorial for reflex-dom. It shows how to write Haskell programs with a graphical user interface. It contains an introductionary text and examples in short bits.

Reflex-Dom is a library to create Haskell applications with a Graphical User Interface (GUI). The GUI is based on the popular Document Object Model (DOM) that is used in the Internet Browsers. Therefore Reflex-Dom programs can be run in the Web Browser or as a Webkit-Gtk application.

Reflex-dom is based on Reflex, a Haskell implementation of Functional Reactive Programming.

It's not necessary to be a Haskell guru to follow this tutorial. A basic understanding of Haskell and the concepts of Functor, Applicative and Monad is enough. With Reflex-Dom you can write GUI applications in Haskell without understanding the concepts of State Monad or Monad Transformers. You need also a basic background on HTML and on Cascaded Style Sheets (CSS). Of course, the more experience you have, the easier it is.

Start by cloning this repository with git clone https://github.com/hansroland/reflex-dom-inbits. Continue by installing Reflex.Dom. The preferred installation method is to use the reflex-platform from https://github.com/reflex-frp/reflex-platform. Alternatively you can use stack, however, this will take a long time. If you use stack, I recommend to use version 1.24.0.2 of cabal. I was unable to run stack setup with cabal 2.0.0.0.

Then read the file tutorial.md.
