What problem does it solve?
Kotlin is a popular language for JVM development, but applying functional programming patterns safely at scale can be verbose and error-prone. This skill consolidates Kotlin FP patterns using Arrow, the Raise DSL, and coroutine-based effects to help engineering teams model domain logic with clarity and safety.
Core Features & Use Cases
- Domain modeling with sealed hierarchies and data wrappers to enforce invariants
- Effect management and error handling with Arrow Raise DSL and coroutines
- Composable pipelines and pragmatic FP approaches suitable for backend services and Android apps
- Real-world use cases include validating domain constraints, composing asynchronous operations, and cleanly handling failures
Quick Start
Create a Kotlin project, add Arrow dependencies (arrow-core, arrow-fx-coroutines) and a test framework, then run the tests to see functional patterns in action.
