Roll your own Computation blocks in Kotlin
Wed Dec 16 2020
Computation blocks empower library authors and users to build ad-hoc operators and DSLs over any data-type getting rid of API complexity and simplifying composition. In this talk, we will learn how we can build Computation blocks over Kotlin suspend functions & the Arrow Continuations library's reset / shift capabilities. We will demonstrate the composition of well known JVM data-types and patterns such as lists, futures, streams, and IOs, where callback chains can be simply replaced by a single

Fight Complexity with Functional Programming
Thu Nov 19 2020
A Metric-driven approach to reduce Cognitive Complexity in a code base, using Functional Programming, demoed hands-on, by solving a complex real-world ubiquitous design challenge - REST API Bulk Request Validation, with an extensible Framework that separates what-to-do (Validations) from how-to-do (Validation Orchestration). Let's do a case study of a successful implementation done by our team in the world's largest SaaS org, Salesforce, using Kotlin and Arrow.

Asynchronisme et hexagone en Kotlin avec ArrowKt
Thu Jun 11 2020
J'aime bien le DDD et surtout les architectures hexagonales. Avoir un domaine auto-portant et non couplé à des blocs techniques comme Spring (ou autres) apporte beaucoup dans la testabilité et l'évolutivité de l'application.
