This course introduces Cats Effect as a tool for building resource-safe and concurrent applications. Cats Effect is a library that makes it easy to write code that effectively uses multiple cores and doesn’t leak resources. This makes building complex applications, such as highly concurrent services, much more productive. This course aims to introduce the core concepts in Cats Effect, giving you the knowledge you need to go further with the library in your own applications. This course is not, however, a detailed dive into every aspect of Cats Effect. Our aim is to cover everything you need to know and set you up so you can rapidly learn additional details on your own if needed.
To benefit from this course you should have about a year’s experience with Scala, or equivalent experience with a typed functional language such as Haskell or OCaml. Familiarity with functional programming methods like map, applicative mapN, and flatMap is required.
