This is a one day Reactive workshop to implement Reactive application using Akka and Play with Java and Scala examples.

Case study

We are going to build the Cocktail bar:

• Drinks like Akkarita, Mai Play and Pina Scalada are served to guests.
• Guests can get drunk, waiters can get frustrated
• Barkeepers can become bottlenecks
• Mission: Keep Hakky Hour healthy!

• Add activator to your PATH
  • Unix systems: export PATH=$PATH:/path/to/activator-dir
  • Windows: Update the path in the global environment variables
• Clone this repo
• cd to the cocktail-bar directory
• start activator: cocktail-bar$ activator This should take you to the activator interactive shell
• Play with some activator commands listed below

activator is our build tool for this project

Summary of important Activator Commands

• exit ends the activator session
• help lists the available commands
• compile compiles the main sources
• console starts the REPL with the project on the classpath
• run looks for an application and runs it
• clean deletes all output in the target directory
• reload reloads the activator session

Setup an IDE (IntelliJ IDEA)

Setup an IDE (Eclipse)

• You can download the prepackaged and preconfigured Scala IDE for your platform from scala-ide.org/download/sdk.html

• Go to your cocktail-var activator console and run the command eclipse with-source=true

  <activator prompt>eclipse with-source=true

• This will generate eclipse project files.

• Import the cocktail-bar project in eclipse
