Configuration
|
|
=============
|
|
> Loads the configuration file and acts as an interface to it.
|
|
|
|
###
|
|
|
|
# **Requires:**
|
|
|
|
# - [Logging](logging.html)
|
|
log = require './logging'
|
|
|
|
# - Node.js Modules: [fs](http://nodejs.org/api/fs.html) and
|
|
# [path](http://nodejs.org/api/path.html)
|

##Module call
|
|
|
|
Calling the module as a function will make it look for the `configPath` property in the
|
|
args object and then try to load a config file from that relative path.
|
|
@param {Object} args
|
|
###
|
|
exports = module.exports = ( args ) ->
|
|
args = args ? {}
|
|
log args
|
|
if typeof args.configPath is 'string'
|
|
loadConfigFile args.configPath
|
|
else
|
|
loadConfigFile path.join 'config', 'config.json'
|
|
module.exports
|
|
|
|
###
|
|
Tries to load a configuration file from the path relative to this module's parent folder.
|
|
Reads the config file synchronously from the file system and try to parse it.
|
|
|
|
@private loadConfigFile
|
|
@param {String} configPath
|
|
###
|
|
loadConfigFile = ( configPath ) =>
|
|
@config = null
|
|
try
|
|
@config = JSON.parse fs.readFileSync path.resolve __dirname, '..', configPath
|
|
if @config and @config.http_port and @config.db_port and
|
|
@config.crypto_key and @config.session_secret
|
|
log.print 'CF', 'config file loaded successfully'
|
|
else
|
|
log.error 'CF', new Error """Missing property in config file, requires:
|
|
- http_port
|
|
- db_port
|
|
- crypto_key
|
|
- session_secret"""
|
|
catch e
|
|
e.addInfo = 'no config ready'
|
|
log.error 'CF', e
|
|
|
|
|
|

Fetch a property from the configuration
|
|
|
|
@private fetchProp( *prop* )
|
|
@param {String} prop
|
|
###
|
|
fetchProp = ( prop ) => @config?[prop]
|
|
|
|
###
|
|
***Returns*** true if the config file is ready, else false
|
|
|
|
@public isReady()
|
|
###
|
|
exports.isReady = => @config?
|
|
|
|
###
|
|
***Returns*** the HTTP port
|
|
|
|
@public getHttpPort()
|
|
###
|
|
exports.getHttpPort = -> fetchProp 'http_port'
|
|
|
|
###
|
|
***Returns*** the DB port*
|
|
|
|
@public getDBPort()
|
|
###
|
|
exports.getDBPort = -> fetchProp 'db_port'
|
|
|
|
###
|
|
***Returns*** the crypto key
|
|
|
|
@public getCryptoKey()
|
|
###
|
|
exports.getCryptoKey = -> fetchProp 'crypto_key'
|
|
|
|
###
|
|
***Returns*** the session secret
|
|
|
|
@public getSessionSecret()
|
|
