- Functional Programming in Scala
by Paul Chiusano and Rúnar Bjarnason - While this book does not
specifically cover Cats, it is a great introduction to functional
programming in Scala in general and covers some of the abstractions
that can be found in Cats.
- Scala with Cats
by Noel Welsh and Dave Gurnell - The aims of this book are two-fold:
to introduce monads, functors, and other functional programming patterns
as a way to structure program design, and to explain how these
concepts are implemented in Cats.
- herding cats by Eugene Yokota
- Scala Exercises by 47 Degrees
offers multiple online exercises to learn about the type classes and
datatypes included in Cats.
- Scala Pet Store
Demonstrates FP techniques while maintaining approachability for people with an OO background. Uses tagless final for the core domain, and popular Typelevel libraries including Cats, Http4s, Circe and Doobie.
- Functional Structures in Scala
by Michael Pilquist offers a series
of lectures about basic functional structures.
- Category Theory for Programmers
by Bartosz Milewski is a series
of category theory lectures oriented towards programmers. The sample code
is in basic Haskell/C++ but the course is designed for programmers of all
background to follow.
- Easy and efficient data validation with Cats by Daniela Sfregola this talk introduces Cats, and some of its most interesting components for data validation. In particular, we’ll discuss some options to achieve efficient and expressive data validation. We will also argue that, compared to other options in the language, Cats is particularly suited for the task thanks to its easy-to-use data types and more approachable syntax.
