Write composable, high-performance, purely functional applications and become productive with Cats Effect, one of the most powerful libraries for Scala
What is Cats Effect?
Cats Effect is a Scala library that allows us to write composable and high-performance applications with pure functional programming.
What?!
Cats Effect comes with a powerful tool called the IO monad, which gives us the power to compose any kind of actions, aka “effects”. Besides that, we get great support for concurrency, parallelism and coordination, all with a strongly typed system (it’s Scala of course).
On more general terms, Cats Effect comes with a group of abstractions that make clear distinctions between different kinds of effects, so we can write more composable code.
The end result is more expressive power, higher performance, fewer bugs, less boilerplate, and most importantly, more happiness and productivity for us as Scala engineers.
This is what you’ll learn in this course.
How this Cats Effect course works
Two words: writing code.
This course is as hands-on as you can get. We learn everything from first principles, not assuming any pre-existing Cats Effect experience, and we build up from there. We discover what effects are, how we can use them, how to compose code, how to design parallel and concurrent applications and how to generalize and make the code modular, all through practical examples. We write 3000 lines of code from scratch.
In this course, we have both theory and practice, so you can not only learn Cats Effect as a tool, but you internalize timeless principles for pure functional programming and high-performance applications.
The course was specifically designed to give you a smooth learning curve by deconstructing Cats Effect and sequencing the topics carefully. Nothing too steep or too boring.
In this Cats Effect course, we go from practice to theory, until pure functional programming gets deep in your bones as a Scala developer.
This course is 100% compatible with Scala 2 and Scala 3.
This Cats Effect course is for experienced Scala developers
Make no mistake – Cats Effect can be difficult, and this course is for advanced developers.
Solid computer science fundamentals are a must: how memory works, how threads work, and some general concepts about parallelism so that you understand the magic machinery of Cats Effect.
You should be very comfortable with Scala as a language, at the level of the advanced course.
As a bonus, if you are familiar with Cats, that’ll help a lot, especially in the later parts of the course.
Even if you’re experienced, learning Cats Effect on your own can take months (I certainly did when I started). This course will compress your learning time to 2-3 days if you’re committed.
Skills you’ll get after the course
First of all, this course will give you everything you need to be productive with Cats Effect
You’ll deeply understand pure functional programming and what “effects” are
You’ll know how to build all sorts of composable programs with IO
You’ll be able write parallel and concurrent code with IOs, Fibers and the tools on top of them
You’ll be able to manage pinpoint program control, with tools like cancellation
You’ll be able to write concurrent, purely functional programs with concurrency primitives
You’ll be able to design your own concurrency tools based on those from Cats Effect
You’ll manage resources in a purely functional way
You’ll be able to write asynchronous code and compose synchronous and asychronous effects seamlessly
You’ll be able to generalize your code for any effect type and still maintain its properties and meaning
After this course, you’ll be able to read and write any code, however complex, that has Scala with Cats Effect in it.
But most importantly, you’ll develop timeless skills that you’ll carry with you for your entire career, regardless of which language or tool you’ll end up using
You’ll deeply understand the practical benefits of pure functional programming in day-to-day projects
You’ll get a new perspective on what composability means
You’ll internalize timeless principles about reusability, effects-as-values, generic and composable code, functional design patterns and more
You’ll become more productive and happier as a developer
