I would like to go over the most relevant tools and changes that can improve your developer experience.

Tooling is one of the topics most discussed in the Scala community. We often complain about its issues or have to deal with its’ imperfect solutions. However, I believe we have gone a really long way during the last few years and we are consistently improving with most Scala core teams being highly conscious of the current imperfections. I would like to go over the most relevant tools and changes that can improve your developer experience.
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.
In this talk, we will take a tour around the `error` function. Starting from the simple use-cases and ending up with sophisticated yet developer-friendly error messages.
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.
