given some environment variables:

MY_PROJECT_PORT=8080
MY_PROJECT_MYSQL_USER=foo
MY_PROJECT_MYSQL_PASSWORD=bar
MY_PROJECT_LOG_INFO=true
MY_PROJECT_PROVISION_RATE=0.2

use them in your application:

envConfig = require 'env-config'

specification =
    port: 'int'
    mysqlUser: 'string'
    mysqlPassword: 'string'
    logInfo: 'bool'
    provisionRate: 'float'

envConfig 'MY_PROJECT', specification, process.env

# =>  {
#       port: 8080,
#       mysqlUser: 'foo',
#       mysqlPassword: 'bar',
#       logInfo: true
#       provisionRate: 0.2
#   }

the first parameter (prefix to all environment variables) is optional.

envConfig throws an exception if an environment variable is empty or can't be converted to the specified type.
