Functional programming in practice, with all its consequences

on YouTube ↗49m

" summary

A practical walkthrough of building a typical microservices application in Scala using pure functional programming: frontend with Scala.js, web services with Akka HTTP, and database persistence with Slick. The talk explains how referential transparency and pure functions map to real tasks (HTTP, DB access, logging, UI), discusses APIs and monads used in these architectures, and shows benefits for modular evolution and reusing the same unit and integration tests.
