In our talk, we will introduce a novel approach to system design— TypeOps — in which the application and infrastructure layers are fused to provide unprecedented safety and productivity for Scala teams. TypeOps leverages the compile-time guarantees of strongly-typed languages to prevent incidents during deployments by enforcing a wide selection of invariants. We will show how to embrace the world of operations by treating Scala applications as strongly-typed Pulumi resources, enabling the "if it compiles, it works" experience at the scale of entire systems.
In this talk, I'd like to share how the Iron library and features from Scala 3 helped us build a solution which is safer, more robust, and easier to maintain.
I will demonstrate how Pillars can take you from zero to production in record time. By leveraging Pillars’ integration of well-known libraries, you can bypass the usual complexities of setting up observability (traces, metrics, and logs), database access, API calls, and feature flag management.
During the talk, we’ll build a small effect system using solely Scala 3 context functions step-by-step.
In this talk, I'll look at the different uses to which tagless final is put to, and see what we can learn about when it is useful and when it just gets in the way.
