Confisto

Confisto is a simple configuration loader for node.

Features

• Multiple parsers (currently only json included)
• Can read directories with extra configuration files

API

The API is fairly simple. The module exports a single function confisto.

confisto(params, cb)

params

• file: File to load that contains the main configuration.
• dir: Directory to read and load that contains many seperate configuration files. Optional.
• defaults: Object with default values or path (string) to a file with default values. Optional.
• parser: Parser to use while loading files Optional. (default 'json')

cb(err, config)

Function to call when done loading configurations.

• err: Error in case of an error
• configs: Object containing the result of merging the configuration files together

Example

var confisto = require('confisto')

confisto({
  file: 'my.conf'
, defaults: {
    logPath: '/var/log/my/errors.log'
  , dbconn: {
      host: 'db.example.com'
    , port: 1337
    }
  , users: ['dan']  
  }
}, function (err, config) {
  if (err) {
    console.error(err)
    process.exit()
  }
  console.log(config)
})

my.conf

{ "logPath": "templog.log
  "dbconn": {
    "host":  "localhost"
    "user":  "root"
  }
  "users": ["joe"]
}

will print

{ logPath: 'templog.log'
, dbconn: {
    host: 'localhost'
  , user: 'root'  
  }
, users: ['dan', 'joe']
}

confisto.keep(ns, config)

Keep configuration object config under namespace ns so that it can be obtained from other files.

confisto.get(ns)

Get the configuration object of namespace ns

Example

// file1.js
var confisto = require('confisto')
  , func     = require('./file2')

confisto({
  file: 'main.conf'
}, function (err, config) {
  // handle err
  confisto.keep('main', config)
  func()
})

// file2.js
var confisto = require('confisto')

module.exports = function () {
  var mainConfig = config.get('main')
  console.log(mainConfig.logFile)
}
