Architectures Using Functional Programming Concepts

on YouTube ↗41m

" summary

Uses Kotlin plus the open library kategory to replace RxJava and ad-hoc callbacks with concrete functional types: Either for errors, IO for wrapping side effects, and Reader for implicit dependency injection. Demonstrates collapsing nested monads with monad transformers and monad comprehensions so use cases avoid triple mapping. Provides Android sample apps (four variants) that run and test by supplying different Context records; unsafe runs happen only at the view edge. Shows clearer types, easier end-to-end testing, and fewer mocks.
