ncon

Configuration by environment for nodejs

Install

$ npm install ncon

Usage

Create a single directory for all configuration files (.json). In this case I have 'config/mongo.json'.

ncon needs to be boostrapped with location of config files Example bootstrap (app.js or similar file):

app.js

// Bootstraps ncon with config files dir
var config = require('ncon');
config.init(__dirname + '../config');

Once ncon has been initialized, there is not need to initialize it later:

mongo.js

// Get mongo configuration
var config = require('ncon');

var mongoConfig = config.get('mongo');

Config Files And Environments

ncon can merge config based on the NODE_ENV, or can be overriden in the init function Lets say my config directory looks like this:

config/
  mongo.json
  mongo.development.json
  mongo.production.json
  mongo.test.json

mongo.json acts as the default configuration file mongo.*.json will extend and overwrite any properties (and nested properties) in mongo.json * is desired environment

The default environment is development. This can be overriden in two ways

Example 1: Hard code the desired environment

var config = require('ncon');

// Load and merge 'test' environment files
config.init(__dirname + '../config', 'test');

Example 1: Use environment variables

$ NODE_ENV=development node app.js

// Load 'test' environment files
var config = require('ncon');

// Load and merge 'test' environment files
config.init(__dirname + '../config');
