  Node.js Application Configuration

  

Thank you for your detailed answer. I think you did miss the correct approach to using ENV vars in the config module, which would be to have a separate file called 'custom-environment-variables.json' that maps your environment variables to the right property. For example: config/default.js module.exports = { db: { user: 'dev-user', password: '123456', host: 'db', name: 'application' } } config/custom-environment-variables.json { "db": { "user": "DB_USER", "password": "DB_PASSWORD", "host": "DB_HOST" } } db.js const dbConfig = require('config').get('db'); console.log(dbConfig); Run: DB_USER=prod-user DB_PASSWORD=abcdef DB_HOST=prod node db.js Output: { "user": "prod-user", "password": "abcdef", "host": "db", "name": "application" } Config composition is actually configs greatest feature I would say. Though the priority chain in the config module is hardcoded (see: https://github.com/lorenwest/node-config/wiki/Configuration-Files), while in yours you can actually which source takes priority.
