Learn how to apply the Functional Programming paradigm to your backend RESTful API.

Building functional Ktor backends

Arrow provides utilities to enable Functional Programming in Kotlin. It also provides integration with the Kotlin stdlib suspend system, so it has goodies to easily integrate Arrow with any existing codebases using suspend.

In this mini-workshop, you will learn to:

  • How to separate concerns in a program (algebras vs runtime)
  • How to encode our Ktor endpoints using IO and its integration with suspend.
  • How to keep effects under control using IO and ArrowFx.
  • How to integrate IO and ArrowFx with side effects flagged as suspend.
  • Approach to concurrency using IO and ArrowFx.
  • How to control, recover from, and model errors into our domain.
  • Write tests for your functional program.

A Q&A session will immediately follow this mini-workshop. Class size is limited to 20 attendees so make sure to register in advance.
