Pavel Shirshov & Michael Feldman at #ScalaUA - distage: Modern Dependency Injection for Scala

Pavel Shirshov and Michael Feldman introduce distage, a dependency injection framework for Scala designed for purely functional programming.

Pavel Shirshov & Michael Feldman at #ScalaUA - distage: Modern Dependency Injection for Scala (remote session) Many Scala developers nowadays consider using Dependency Injection frameworks an anti-pattern incompatible with modern FP settings. We argue that it's just a consequence of a bad experience with legacy Java runtime reflection-based implementations that lack features important for modern functional programming, such as a first-class support for higher-kinded types. We argue that as a paradigm for structuring purely functional programs, DI with automatic wiring compares favorably against implicits, monad transformers, free monads, algebraic effects, cake pattern at all, enabling scaling and a degree of modularity unachievable by any manual wiring approach. This talk covers DIStage – a transparent, flexible and efficient DI framework for Scala that enables late binding, testability, effect separation and modular resource management at scale, working with, instead of compromising the Scala type system.
