Offline-First WebApps with Hoodie and PureScript

Some time ago I tried to learn Elm. And believe it or not, I failed to compile a simple Hello-World program. Later I figured out that some interfaces have changed between certain versions of Elm making my failure inevitable. Long story short: the tutorial I found on the net was outdated and I didn’t know it. Well, how could I know this? Or more precisely: if a change in the language can hit a beginner so hard will he/she be willing to continue? In my case I ended up with PureScript. Often I hear or read that PureScript is ‘harder’ to learn […]

Managing Application State with PureScript & Redux

PureScript-Redux is a small library which helps to utilize the Redux state container with PureScript. Although I have almost no experience with React, which is the most prominent ecosystem for using Redux, I thought it would be a nice learning exercise to create a set of Redux-Bindings for writing WebApps in PureScript. Redux itself is heavily, and rightfully so, promoting the benefits of using pure functions for managing the application state and PureScript, being a Haskell-dialect, is a purely functional language. Therefore, it seemed to me very logical to try to combine them together. But because I’m also a PureScript-Beginner and still learning […]

Using Web Streams with PureScript

This is an updated version of the original article. I want to thank @joseanpg for the corrections and the idea regarding TextEncoder. Usually, my articles are mostly too long, filled with too many screenshots and philosophy. But this time I’ll try to remain concise and, hopefully, more precise than usual. I’ll refer to Jake Archibald’s article on Web Streams and his prediction that they’ll become the dominant web technology of the Year 2016 (in combination with Service Workers, of course). The article is filled with lots and lots of nice code examples you can basically copy & paste into your browser (some of […]

WebApps with PureScript & RactiveJS

It’s been a while since I wrote my last article and. Actually, I planned to write the second part of my Scala Crash Course but in the mean time I adopted an orphaned (abandoned?) project called purescript-ractive that’s related to my favorite UI-Library, RactiveJS, and is written in a little, amazing language called PureScript. As many of you already know there are so many different languages that compile to JavaScript. There’s even a COBOL transpiler for JS! Therefore I’ll surely not waste your time discussing the (dis)advantages of Transpiling-to-JS vs. Writing-in-JS. Instead, I’ll try to describe the advantages of PureScript by explaining a small […]
