Sentry is an error tracking service that helps you quickly track errors in many environments. While it’s not the only option for error reporting (Rollbar comes to mind since they sponsor most of the podcasts I listen to), Sentry is my favorite option. Today, we’re going to setup Sentry reporting for our Scala / Play […]
Kotlin to Scala. Scala to Kotlin. Two contenders for my heart. In the left corner, we have the new comer! Weighing in at just over 1.2MB — The Ambassador of Android: Kotlin! And in the right corner, we have the long-time favorite, weighing in at just over 5.3MB — The Archduke of Akka, The Sultan […]
It’s pretty common to find yourself working with generics in Scala, but you may find yourself where you want a generic with some constraints. Generally, these constraints can be boiled down to “Subclass” or “Superclass” and Scala offers functionality out of the box to help facilitate this.
Sometimes, you may find yourself in a situation (like using Scala with Spring) where you need to generate a Java bean but would like to do that in Scala. By default, Scala classes don’t adhere to the requirements of the Bean definition, namely autogenerating getters and setters. Thankfully, there is a BeanProperty decorator that can […]
Scala has, in it’s core library, several classes that are intended to contain (at some point or another) some instance of another class. A few examples of this are seen in Option and Future. These container classes allow you to act upon values that may or may not exist or even to work with values that should appear in the future (hence the name “Future”). The idea of these container classes is fundamentally simple.
A common theme with web applications is to run tasks in the background. Commonly, they’re ran at set intervals. You’ll find data processing servers, online-game servers, and several other types of servers using regularly scheduled background tasks and today, you’ll learn how to implement these tasks in Play with Scala.
