Simple configuration which is overridable through env vars

config.coffee

# Find the appropriate setting for the provided key
module.exports = config = (key) ->
  # return setting from environment variable
  if env_value = process.env[key.toUpperCase()]
    try
      return JSON.parse(env_value)
    catch err
      if err instanceof SyntaxError
        return env_value
      else
        throw err
  # return default value
  config[key]

config.mongo_url       = "mongodb://localhost/bibliaolvaso"
config.session_secret  = "YOUR SECRET HERE"
config.cookie_max_age  = 365 * 24 * 3600000
config.facebook_app_id = 'FACEBOOK KEY'
config.facebook_secret = 'FACEBOOK SECRET'

config.default_user_values =
  last_chapter: '/ujforditas/1moz/1'
  ui: {format: 'continuous', text_size: 'medium'}

# Allow overriding defaults with environment specific settings
try
  env_settings = require "./#{process.env.NODE_ENV ? 'development'}"
  for key, value of env_settings
    config[key] = value
