Molybden 1.5.5: environment variables in molybden.conf.json
Now you can use the environment variables in molybden.conf.json. It’s useful
when you want to use the same configuration file for different environments (
e.g. development, staging, production)and you want to use different values for
some properties in each environment.
Use the ${ENV_NAME} syntax in the config file to reference the environment variable.
