configury v0.3.0

configury

Easy management of environment based configuration

Installation

  npm install configury

Usage

configury(path, defaultSection)

Using in-memory configuration

var configury = require('configury')
  , config = configury()

Using configuration file on disk

var configury = require('configury')
  , config = configury('./properties.json')

Using default config section other than 'global'

var configury = require('configury')
  , config = configury('./properties.json', 'myDefaultConfigSection')

config.raw()

var configury = require('configury')
  , config = configury('./properties.json')

config.raw()
//-> { "global": { "foo": "bar" }, "development": { "foo": "bar" } ... }

config.write(path, cb)

Save the current configuration in memory to disk

var configury = require('configury')
  , config = configury('./properties.json')

// Write to './properties.json' file on disk synchronously
config.write()

// Write to './properties.json' file on disk asynchronously
config.write(false, function (err) {
  if (!err) console.log('Yeah')
})

// Write to './myBackupProperties.json' file on disk asynchronously
config.write('myBackupProperties.json', function (err) {
  if (!err) console.log('Yeah')
})

// Write to './myBackupProperties.json' file on disk synchronously
config.write('myBackupProperties.json')

config.set(key, value)

Setting a variable in 'global' configuration

var configury = require('configury')
  , config = configury('./properties.json')

config.set('Alice', 'Bob')
config.raw()
//-> { "global": { "Alice": "Bob" } ... }

Setting a variable in 'myCustomGlobal'

var configury = require('configury')
  , config = configury('./properties.json', 'myCustomGlobal')

config.set('Alice', 'Bob')
config.raw()
//-> { "myCustomGlobal": { "Alice": "Bob" } ... }

config.section(section)

var configury = require('configury')
  , config = configury('./properties.json', 'myCustomGlobal')

var mySection = config.section('mySection')
//-> mySection = { set: function(key, value), merge: function(object) }

Setting a variable in 'mySection'

var configury = require('configury')
  , config = configury('./properties.json')
  , mySection = config.section('mySection')

mySection.set('Alice', 'Bob')
config.raw()
//-> { "global": { ... } "mySection" { "Alice": "Bob" } }

config.merge()

Merging an object over a property in the configuration

var configury = require('configury')
  , config = configury('./properties.json')

config.set('foo', 'bar')
//-> { "global": { "foo": "bar" } ... }
config.merge({ 'global': { 'foo': 'woo' }, 'pickles': 'bananas' })
//-> { "global": { "foo": "woo" }, "pickles": "bananas" }

Merging an object over a property in 'mySection'

var configury = require('configury')
  , config = configury('./properties.json')
  , mySection = config.section('mySection')

mySection.set('foo', 'bar')
//-> { "global": { ... } "mySection": { "foo": "bar" } }
mySection.merge({ 'foo': 'woo' })
//-> { "global": { ... } "mySection": { "foo": "woo" } }

Substitution

By default, configury will substitute any values that match the pattern: %string%. This will substitute the current value with the value of that key if it exists. E.g:

var configury = require('configury')
  , config = configury()

config.set('url', 'http://localhost:3000')
config.set('loginUrl', '%url%/login')

console.log(config().loginUrl)
//-> 'http://localhost:3000/login'
