##Module call
|
|
|
|
Calling the module as a function will make it look for the `relPath` 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.relPath is 'string'
|
|
loadConfigFiles args.relPath
|
|
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} relPath
|
|
###
|
|
loadConfigFile = ( relPath ) =>
|
|
try
|
|
@config = JSON.parse fs.readFileSync path.resolve __dirname, '..', relPath
|
|
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]
|
|
|
|
###
|
|
Answer true if the config file is ready, else false
|
|
|
|
@public isReady()
|
