How to store Node.js deployment settings/configuration files?

by

I use a package.json for my packages and a config.js for my configuration, which looks like:

var config = {};

config.twitter = {};
config.redis = {};
config.web = {};

config.default_stuff =  ['red','green','blue','apple','yellow','orange','politics'];
config.twitter.user_name = process.env.TWITTER_USER || 'username';
config.twitter.password=  process.env.TWITTER_PASSWORD || 'password';
config.redis.uri = process.env.DUOSTACK_DB_REDIS;
config.redis.host="hostname";
config.redis.port = 6379;
config.web.port = process.env.WEB_PORT || 9980;

module.exports = config;

I load the config from my project:

var config = require('./config');

and then I can access my things from config.db_host, config.db_port, etc… This lets me either use hardcoded parameters, or parameters stored in environmental variables if I don’t want to store passwords in source control.

I also generate a package.json and insert a dependencies section:

"dependencies": {
  "cradle": "0.5.5",
  "jade": "0.10.4",
  "redis": "0.5.11",
  "socket.io": "0.6.16",
  "twitter-node": "0.0.2",
  "express": "2.2.0"
}

When I clone the project to my local machine, I run npm install to install the packages. More info on that here.

The project is stored in GitHub, with remotes added for my production server.
