Node env config loader

Load config from files and environment.

Default config file

The default config file is config/config.json

Application environment config file

If the APPLICATION_ENV variable is set, the file related to will be loaded.

For example if APPLICATION_ENV is set to live, config/config_live.json will be loaded.

Environment variables

All the variables beginning with your application name will try to be loaded.

For example if your application name is my-app and you have the following variables:

process.env.my_app_port = 3000;
process.env.my_app_redis_password = 'foobared';

The config will contain the following json:

 {
     "port": 3000,
     "redis": {
         "password": "foobared"
     }
 }

Override a key

if you have a config.json

{
    "key1": {
        "key11": "value1",
        "key12": "value2"
    }
}

and a config_APPLICATION_ENV.json

{
    "key1": {
        "key13": "value1"
    }
    "override": ["key1"]
}

key1 will be {"key13": "value1"}

Extra configuration

The application name will be automatically added under the name key.
