Overview

Essential Scala is an introduction to Scala for professional developers. Essential Scala covers the core Scala patterns that new developers need to be productive in the language. It's designed to get you productive as quickly as possible, and avoid the dark and confusing corners of the language.

Building

Essential Scala 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 which 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:
