Arrow, a collection of libraries that complement the Kotlin ecosystem with functional patterns and data types, made a splash at the recent Kotlin Dev Day conference.

This in-person conference for people interested in Kotlin took place on May 19 at the Johan Cruijff Arena in Amsterdam. Experts from around the globe converged to network, learn, and share information. Speakers presented talks on a wide variety of topics related to the Kotlin programming language, including presentations focused on Arrow.

International speaker Karin-Aleksandra Monoid, who is a Senior Software Engineer and Google Developer Expert in Kotlin, delivered a talk titled, “Extending kotlinx.serialization functionality with Arrow Meta.” This talk demonstrated how Arrow Meta (a functional companion to Kotlin’s compiler) can be used to help solve the challenges of migrating from the Jackson serializer to kotlinx.serialization.

47 Degrees Trainer and Software Engineer Alejandro Serrano Mena also presented an Arrow-related talk at Kotlin Dev Day. His talk, titled “Super-charge your build with Arrow Analysis,” demonstrated this plug-in for the Kotlin compiler, which essentially supercharges your compilation pipeline to make your code safer and more robust.

This recent Kotlin Dev Day conference marked the second edition of the Kotlin-focused event. The sold-out conference was a success, and it marked the first return to in-person conferences for many in the community, including a group from 47 Degrees.

47 Degrees CTO Raúl Raja was among the 47ers at the conference. “At Kotlin Dev Day, we had a blast reuniting with many friends in the community, enjoying an incredible venue, and a program packed with top talks and speakers,” he said. He continued, “Finally, we were pleasantly surprised that many attendants and speakers knew and discussed Arrow in talks and hallway conversations.”
