nconf-transforms

Similar to .NET web.config transforms, nconf-transforms allows you to load nconf configuration files based on convention. By default reads the NODE_ENV environment variable to select what config file to transform. Currently only supports JSON format.

Usage

require('nconf').argv().env() // don't forget to load your environment/argv variables if you want them!

var transform = require('nconf-transforms');

transform({
  dir: './config',
  reload: true // reload nconf when the config file changes
  format: require('nconf-yaml')
});

where your file tree is something like

/app
  app.js
  /config
    settings.json
    settings.production.json

settings.json

{
  "someConfig": "someValue"
}

app.js

var nconf = require('nconf');
console.log(nconf.get('someConfig')); // "someValue"

API

transform(options)

Loads your base configuration and transforms it using the NODE_ENV environment variable to find the transform file.

Options:

• dir: String. The directory to find the configuration files. Defaults to __dirname, so set it anyway.
• fileName: String. The name of your configuration files (i.e settings.json, settings.production.json). Defaults to settings
• reload: Boolean. Toggles reloading of configuration when the base config changes.
• environment: String. The environment to transform to. Defaults to process.env['NODE_ENV']
• format: String. The nconf file format to use. Defaults to JSON.

Returns the nconf object so you can chain loading other configuration types/files.
