4. Disclaimer 1. My Level -> A1 (Wannabe) 2. Research > Coding
5. Why I Choose Scala ? 1. Twitter: From ruby to scala (backend) 2. Foursquare: From php to scala (all) 3. Mindtalk : From python to scala from dynamic typing to static typing
6. Problem With Scala 1. Internet Connection 2. Compile 3. SABAR
7. Companies Using Scala 1. Twitter 2. Foursquare 3. Netflix 4. Ebay 5. Tumblr 6. AirBnB 7. Mindtalk 8. …………...Apple?
8. Scala’s Frameworks 1. Lift 2. Play (hello world) 3. Scalatra 4. Finatra (proved) 5. Splay (toolkit)
9. Scala Web Server 1. Finagle (Twitter) -> Finatra 2. Socko 3. spray-can
10. Scala NoSQL Framework 1. Casbah (Mongodb) -> proved 2. ReactiveMongo : Asynchronous Mongodb 3. Sandra : Apache cassandra & Scala 4. Scala-redis 5. Gizzard
11. Scala Unit Test 1. Scalatest -> proved 2. Scalacheck -> property based unit test 3. Spec2 -> bdd
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 3. Scalatest 4. sbt pack https://github.com/hiraq-scala/google-shorten-url
