Test Scala Config

Table of Contents

• Requirements
• Configuration files

• Running in PROD environment

This is a sample project to demonstrate how to use a "multi-environment" configuration setup for Scala with TypeSafe’s Config library.

See this Stack Overflow thread for more info.

Requirements

• Scala 2.11

• SBT 0.13

Configuration files

• the DEV configuration

• the PROD configuration (note that the DEV is in included, so you only have to override what you want)

Running in DEV environment

The DEV environment is the default one, just start an SBT session and run the main program.

Running in PROD environment

Simply specify the TypeSafe configuration file to use by passing the config.resource system property (documented here).

This can be done either by passing the system property when starting the SBT session sbt -Dconfig.resource=prod.conf or by editing the build.sbt file and adding/uncommenting these lines:

fork := true
javaOptions := Seq("-Dconfig.resource=prod.conf")
