rc

the non configurable configuration loader for lazy people.

Usage

the only option is to pass rc the name of your app, and your default configuration.

  var rc = require('rc')(appname, {
    //defaults go here.
    port: 2468
  })

Standards

Given your application name, rc will look in all the obvious places for configuration.

  • command line arguments (parsed by optimist)
  • enviroment variables prefixed with ${APPNAME}_
  • if you passed an option --config file then from that file
  • $HOME/.${APPNAME}rc
  • $HOME/.${APPNAME}/config
  • $HOME/.config/${APPNAME}
  • $HOME/.config/${APPNAME}/config
  • /etc/${APPNAME}rc
  • /etc/${APPNAME}/config
  • the defaults object you passed in.

All configuration sources that where found will be flattened into one object, so that sources earlier in this list override later ones.

Formats

Configuration files may be in either json or ini format. Since ini, and env variables do not have a standard for types, your application needs be prepared for strings.
