This document discusses various development tools in Scala that can increase programmer productivity, including SBT for build automation and dependency management, Scalatest for unit testing, and g8 and conscript for project generation. It also provides an overview of Scala frameworks for web development, NoSQL, and more. Finally, it demonstrates using g8, SBT, and pack to generate, build, and package a Scala project that integrates with the Google URL Shortener API.

12. For Development
1. sbt (plugins: assembly / pack)
2. conscript
3. g8

13. SBT - (not so)Simple Build Tools
1. Scala
2. Java
3. c++

14. SBT - What’s for
1. Choose Scala Version
2. Library dependency management
3. Compile & package

15. SBT - Plugins
1. Assembly - Fat jar (Finatra)
2. Pack - compile, packaging + installing
(support unix (linux) & windows), support
versioning
https://github.com/sbt/sbt-assembly
https://github.com/xerial/sbt-pack

16. Conscript & g8
conscript : install & update
g8 : generate files & directories from
templates published in github

17. g8 example template
1. fayimora/basic-scala-project : simple scala project + scala test
2. pmandera/basic-scala-project : simple scala project + spec2
3. scalatra/scalatra-sbt : basic scalatra template

18. Installation - Conscript
curl https://raw.githubusercontent.com/n8han/conscript/master/setup.sh |
sh

19. Installation - g8
curl https://raw.githubusercontent.com/n8han/conscript/master/setup.sh |
sh

20. Command line
1. g8 fayimora/basic-scala-project
2. sbt

21. Setup sbt pack
packSettings
packMain := Map("shorten" -> "api.hiraq.
google.shortenurl.Shorten")

22. Demo - Google ShortenURL API
1. g8 -> fayimora/basic-scala-project
2. Basic scala project
