Functional Programming in Spring with Arrow, Lenses and Effects
With the introduction of Kotlin as a supported language, as well as the Arrow functional programming framework, building a functional web application with Spring has never been easier. More importantly, the conversion path from an Object Oriented Spring app to a Functional Programming Spring app can be accomplished with little risk and much reward.
Spring is the most widely used JVM web framework. For many years, the paradigm it has adopted has been object-oriented, stateful and imperative. This talk will show how to take such a codebase and refactor it into a functional programming style. It will show the benefits of this approach with regards to clarity, stability, safety and testability.
Outline/Structure of the Talk
Introduction to Spring 5 and its Functional Aspects
Applying Kotlin and some Spring-Fu
Introducing Arrow and applying it piece by piece
How it all comes together, and where to go from here
Learning Outcome
- how to apply functional concepts to an existing OO application
- steps to take to incrementally refactor a codebase piece by piece
- what fp concepts are available in Kotlin thanks to the Arrow framework
- how to leverage these concepts to get the most value with the least interruption to the team's performance
Target Audience
Java/Kotlin or other JVM developers who want to introduce FP into their codebases
Prerequisites for Attendees
No pre-reqs. Some familiarity with Spring, Kotlin or Java helpful.

YOW! Lambda Jam is a conference for applied functional software developers. The conference provides the opportunity to share experiences so that attendees can improve software development using the principles, practices and tools of functional programming.
Lessons learned and specific practices are very important for this pragmatic conference, hence we encourage submissions which deal with the practical challenges of functional programming such as: developing commercial FP proficiency; leveraging good theory or algorithms to make better practice; pragmatics of applying a specific language or technique in the real world; production challenges such as deployment speed / space; lessons learned taking the wrong road.
The first day is tutorial day which provides a small number full day tutorials on topics for novices, and intermediate to advanced functional programmers. This was a very and popular feature of our 2018 conference.
We welcome submissions for talks (30 minutes), workshops or code jams (90 minutes) or full-day tutorials. .
| Call for Presentations Open Until | 22 March, 2019 |
