SpinGo <3 Scala

At SpinGo, we've been building our software on Scala, a staticly-typed, multi-paradigm programming language for the JVM. We've enjoyed it and would like to share our experience.

Why did we choose Scala?

Two years ago, the entire backend was written in CakePHP (with the traditional server-side-rendered); we've felt that the rich-client / API approach to writing software can offer far better user experience; additionally, tracking some amount of state in the browser can make many interaction patterns drastically simpler to implement. Our PHP stack had become tremendously difficult to maintain; it lacked Unit tests, the coding style was heavily imperative, and 500+ line methods were less rare than I'd like.
