This is an example ZIO app that demos how you might use zio-config and ZLayer in a real app. It has 2 mock dependencies (database & upstreamApi) that need to be configured.
Run the app:
sbt stage
# Run in dev
database_password=dev-secret ./target/universal/stage/bin/zio-config -Dconfig.resource=application-dev.conf
# Run in prod
database_password=prod-secret ./target/universal/stage/bin/zio-config -Dconfig.resource=application-prod.conf
# Run with external config
database_password=ext-secret ./target/universal/stage/bin/zio-config -Dconfig.file=application-external.conf
Loads config in srm/main/resources/application-.config according to typesafe config rules and super imposes any config values provided via environment variables. This allows you to specify secrets as environment variables outside of your baked-in config file.
