yaml-config

Manage your configuration based on NODE_ENV, all configuration defined with yaml. Shared configuration can be put under default key, different settings under each enviroment name.

Installation

$ npm install yaml-config

Usage

In the setting file at config/app.yaml

default:
  redis:
    port: 6379                # redis server port
    host: '127.0.0.1'         # redis host
    password: ''              # to use with AUTH
    db: 1                     # the test db
    options: {}
test:
  redis:
    db: 12
production:
  redis:
    db: 0
  new_prop:
    hello: 'world'

In your source code

var config = require('yaml-config');
var settings = config.readConfig('./config/app.yaml'); // path from your app root without slash
console.log(settings.redis.db); // if NODE_ENV is development, prints 1

The readConfig() function takes a second parameter as enviroment name, for example

var settings = config.readConfig('./config/app.yaml', 'test');
console.log(settings.redis.db); // prints 12

The updateConfig() function will take current settings and save them back to the configuration file

var settings = config.readConfig('./config/app.yaml', 'production');
console.log(settings.redis.db); // prints 12
settings.redis.db = 10;
updateConfig(settings, './config/app.yaml', 'production'); //Save 10 to redis.db of the 'production' section
updateConfig({},'./config/app.yaml', 'production'); //Will remove the entire 'production' section

If the settings are used in multiple files, you may want to put the loading code in a seperate file and require it when used, so that config file will be loaded only once.
