Environment Variables Example

Really tiny and simple example about using both envconfig and godotenv as a prerequisite for a 12 factor application.

Usage

Without indicating any environment variable it uses the default values:

$ ./env-vars-example
root:@localhost:3306/dbname

but if you set the environment variables, those take preference:

$ DSN_USERNAME=mario DSN_HOST=fancy.com ./env-vars-example
mario:@fancy.com:3306/dbname
