I wrote a blog post about this subject a couple of years ago and a lot of people read it. Unfortunately it contains some advice that has been proven wrong/not optimal. The re-frame explanation of this concept is nice and understandable, but I wanted to make an interactive example so it's even clearer.
The controller rules, taken from keechma, are centered around pure route data. That's really powerful, as you can use mostly plain Clojure to get what you want from your controllers. Often the solution is dead simple, but it's not always easy to spot. This is a guide to the most useful tricks, it will be expanded as new ones appear!
Most developers will claim that TDD is part of their daily routine. But most of us fail to mention our actual favorite methodology, SDD.
Stackoverflow Driven Development is a very good thing. Sharing knowledge and experience moves everything forward, and we should keep going. But some issues are too large or too important to quick-fix through an upvoted stackoverflow answer. The "best practice" might not be the best for you.
You are here, so you probably heard about the kee-frame framework. It's built on re-frame, and should be easy to learn. Let's see if that's true! If you want to see the full context for the code samples in this tutorial, they're all part of the kee-frame demo app
Re-frame has a simple but powerful architecture that enables you to express yourself in pure data structures even with side-effect heavy code. In this post I will show a simple example of the patterns used.
