node-settings
Simple, hierarchical environment-based app settings.
Installation
npm install settings
Usage
Configuration file config.js
module.exports = {
common: {
storage: {
host: 'localhost',
database: 'server_dev',
user: 'qirogami_user',
password: 'password'
}
},
// Rest of environments are deep merged over `common`.
development: {},
test: {
storage: {
database: 'server_test',
password: 'foo'
}
},
production: {
storage: {
password: 'secret'
}
}
};
Application file app.js
var Settings = require('settings');
var config = new Settings(require('./config'));
// inherited from common
assert.equal(config.storage.host, 'localhost');
// specific to test
assert.equal(config.storage.password, 'foo');
Environments
The environment to use is based on (highest precedence first):
-
forceEnv
property in config file// config/environment.js exports.forceEnv = 'production';
-
$NODE_ENV
environment variableNODE_ENV=production node app.js
-
env
option passed to constructor.new Settings(file, {env: 'test'});
Application Defaults
Property defaults may be preset in code.
var settings = new Settings(file, {
defaults: {
framework: {
views: 'app/views'
}
}
});
assert.equal(settings.framework.views, 'app/views');
Hacking on the source
To compile and test
npm install bake-bash -g
npm install -d
bake test
Notes
globalKey
option has been removed. Do this instead
global.APP = new Settings(file);
