npm install env-config

use

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.
