Get config objects from ENV variables defined in config.env. This module will search for config.env in current directory and bubble down to root.

If config files are elsewhere, they can be specified on the command line using CONFIG=fullpath1;fullpath2 node app.js. These files will override any configs in default config.env, if it exists.

Configuration values can be grouped together using a prefix and plucked out individually.

See node-env-config-shareduration for info on structuring config.env

Usage

#
# config.env:
#

# db configs
DB_VAR1=true
DB_VAR2=false

# redis configs
REDIS_VAR1=true
REDIS_VAR2=false

# app1
APP1_VAR1=1
APP1_VAR2=2

# app2
APP2_VAR1=3

#
# config2.env:
#

# override a config value
APP1_VAR2=100

//
// app.js
//

var config = require('env-config-shared')

// pluck out configs for app1 and app2
config
	.get('app1')
	.get('app2')

// we can now use the configs for app1 and app2
console.info(config.app1)
console.info(config.app2)

Use the default config only

~ node app.js
{
	var1: 1,
	var2: 2
}
{
	var1: 3
}

Override some config using the CONFIG env

~ CONFIG=./config2.env node app.js
{
	var1: 1,
	var2: 100
}
{
	var1: 3
}
