Functional programming in Kotlin with Arrow.kt

Arrow strives to be a great functional companion library for Kotlin. This is not just a matter of style: with this functional style we can describe complex patterns in an easy way, and we aim to showcase a few of them in the context of a Ktor project. We’ll discuss how to handle retries using circuit breakers and schedulers, and how to do validation in a powerful fashion. Along the way, we’ll show a bit of other Arrow projects, like optics and analysis.

The example project used in this video can be found here.

Speakers: Simon Vergauwen, Alejandro Serrano
