Introduction As part of the F# mentorship program my mentor Anthony Lloyd and I have been working on the Fantomas project. Fantomas is like prettier or elm-format but for F#. It was originally created by Anh-Dung Phan and people have suggested that it could be a part of the F# Compiler Service. Fantomas is like prettier or elm-format but for F#. .NET Core The source code of Fantomas is quite advanced so our approach is to focus first on improving the project in general. We noticed it was a bit old in terms of Visual Studio version and dependencies, so…

Introduction Want to use Docker to develop Fable applications? What if I told you it isn't all that difficult? TLDR; How to user Docker with Fable. Docker So the first step with Docker images is that you check whether a suiting image that fits your needs already exists. When I checked Docker Hub for any recent images with the Fable tool chain I didn't really find anything that works with Fable 1.x. I accepted the fact that I would have to create the image myself. If you check the docs for requirements, we'll need: .NET Core Node js Mono…

Introduction 2016 for me personal was the year the I came in serious contact with functional languages. I started looking at F#, applied functional concepts (partial application, immutability, pure functions and so on) in JavaScript, gave RxJS a shot and fell in love with React. A logical next step was looking at Elm. I was first introduced to Elm at a Socrates Meetup a while ago by Thomas Coopman. To be honest I was a bit overwhelmed at the time and a bit skeptical afterwards. I decided to give Elm another shot and learned a lot by following Elm for…

Introduction Nowadays I'm into PHP & Docker. Yep that's right this .NET boy is going wild! As I'm learning all these new concepts it became clear that you don't really start from scratch with PHP but you choose a framework. I ended up choosing Laravel because it is popular, has a beautiful website and there is this thing called Laracasts. Laracasts - It's Kinda Like Netflix for Your Career! Basic Task List In this blogpost we're going to create the Basic Task List example from the Laravel documentation using LaraDock instead of Homestead on Vagrant. To get started I assume:…

Introduction A while ago I wrote some JavaScript to create a custom slideshow. I recently had to revisit that project and I saw an opportunity to fiddle around with RxJS Explaining the problem The way the slideshow works is that it shows three images and moves up one frame at a time. So initially the first three images are shown and the rest are hidden. You press the right button to move forward and the left to move backwards. Of course at the beginning of the slideshow you can't move backwards. Thus the left button is hidden. Once you are…
