ScalaBridge London Jun 20th, 2024

Let's meet at 6pm! ScalaBridge London is a community run group for learning and improving at programming. We always run material for new programmers and each term we choose a new topic for more experienced developers. This term that topic is Cats Effects.

Armored type safety with Iron

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.

Do I miss writing Scala?

I've had the please of working with Scala for many years, as well as other main JVM languages like Java and Kotlin. In this talk, I'd like to reflect on these experiences, what I like/dislike about Scala (and other languages), how certain decisions have affected projects, how these languages have changed over time and how they address different problems. Join me for a fun and possibly opinionated talk about the state of Scala and other JVM languages.

Tapir Tutorial - part 3: Using JSON bodies

In this episode we'll see how to integrate with JSON: parse incoming HTTP requests and serialise outgoing HTTP responses. Along with generating documentation, in a type-safe, programmer-friendly way!

Looking beyond the scope: Scala application from an external lens

In the dynamic landscape of Scala application development, the tendency to focus solely on internal intricacies often obscures a crucial aspect - how the application is perceived from the outside. By observing from a distance, we gain insights into how to enhance resilience, reliability, and overall performance, influencing how we implement our applications. Questions arise: What's the startup time? Can I safely run 2 or more instances? How do I know if it works as expected? Can monitoring/tracing help? Does it shut down gracefully?

Typo 0.20.0

Typo is not just another source code generator; it's your trusted partner in database development. By harnessing the power of PostgreSQL schema definitions and your SQL code, Typo creates a seamless bridge between your database and your Scala code, all while putting type-safety and developer experience (DX) front and center.
