Overview

Scala with Cats teaches core functional abstractions of monoids, functors, monads, and applicative functors using the Cats library and a number of case studies.

Building

Scala with Cats uses Underscore's ebook build system.

The simplest way to build the book is to use Docker Compose:

  • install Docker Compose (brew install docker-compose on OS X; or download from docker.com); and

  • run go.sh (or docker-compose run book bash if go.sh doesn't work).

This will open a bash shell running inside the Docker container that contains all the dependencies to build the book. From the shell run:

  • npm install; and then
  • sbt.

Within sbt you can issue the commands pdf, html, epub, or all to build the desired version(s) of the book. Targets are placed in the dist directory.
