In this talk, we’ll show first the different techniques we can use to apply constraints is our domains. Then, we’ll present Iron, its features, extensions, and integrations. We’ll finish by showcasing a fully integrated constraint-enforcing app.
When designing an application, we often end up with domain-specific types, that all behold constraints that we try to enforce as much as possible: an age is positive, a delivery date can’t be in the past, etc. Modelling the data right is a part of the success of Scala and functional programming in general, but it also brings either boilerplate (we have to do again and again validation), or rely purely on conventions.
But there is hope. Meet the Iron library.
Iron is, a type constraint library that allows us to have a safe, declarative and smarter model. It enables us to have a continuous stream of valid data from our API endpoints to the database, and removed a whole class of bugs. Using advanced features like opaque types, inlines and the new macro system, it offers a true 0 cost, 0 dependency library that doesn't hamper compile time.

Drawing on 25 years of experience as a professional musician and record producer, this will be a beginner focused talk introducing the use of Scala.js and the web audio api for building Scala powered Web Audio Applications.
Let's write a game in Scala Native, for Playdate!
In this talk, we will demonstrate some elegant applications of functional programming in Scala, with even more elegant visual results - all with live code and real-time output.
This talk is my slightly expanded version of that statement, and should hopefully understand what "Free" is, what purpose it serves and where it came from.
I would like to go over the most relevant tools and changes that can improve your developer experience.
