ZIO layers (ZLayers) help us structure our complex services into modules that are independent, composable and easy to understand. Let’s take a look.
An ad-hoc type definition technique for eliminating bugs which are hard to trace, with implementations in Scala 2 via newtypes and in Scala 3 via opaque types.
Although frowned upon by FP purists, creating and managing mutable data structures is important in any language. Scala has some first-class features.
Error handling is likely one of the most frustrating part of programming, and in Scala, there are better and worse ways to do it. Let’s take a look.
