Package Exports

settings

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (settings) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

node-settings

Simple, hierarchical environment-based app settings.

Installation

npm install settings

Usage

Configuration file config/environment.js

exports.common = {
  storage: {
    host: 'localhost',
    database: 'server_dev',
    user: 'qirogami_user',
    password: 'password'
  }
};

// Rest of environments are deep merged over `common`.

exports.development = {};

exports.test = {
  storage: {
    database: 'server_test',
    password: 'foo'
  }
};

exports.production = {
    storage: {
        password: 'secret'
    }
};

Application file

var Settings = require('settings');
var file = __dirname + '/config/environment.js';
var settings = new Settings(file).getEnvironment('test');

// inherited from common
assert.equal(settings.storage.host, 'localhost');

// specific to test
assert.equal(settings.storage.password, 'foo');

Environments

The environment to use is based on (highest precedence first):

forceEnv property in settings file

 ## config/environment.js
 exports.forceEnv = 'production'

$NODE_ENV environment variable
```
 NODE_ENV=production node app.js
```

Environment argument passed to Settings#getEnvironment()

 # the environment argument is ignored if either of the above is set
 settings.getEnvironment('production')

Install Globally

If globalKey option is set, the environment settings are installed into global space.

var settings = new Settings(file, { globalKey: '$settings' }).
                   getEnvironment();

assert.equal($settings.storage.host, 'localhost');

Application Defaults

Property defaults may be preset in code. These defaults may be overridden by the app's external settings.

var settings = new Settings(file, { 
 globalKey: '$settings',
 defaults: {
   framework: {
     views: 'app/views'
   }
 }
}).getEnvironment(); 


assert.equal($settings.framework.views, 'app/views');
