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

Answer

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;

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.
