jarvisnode/modules/config.js

A library written in Node.js used to communicate with my Jarvis project

var fs = require('fs');
var map = null;
var path = null;
var p = require('path');

/**
 * Handle the library settings
 * @module jarvisnode/modules/config
 */
module.exports = {

  init: function(confPath, cb) {
    
    path = confPath;
    
    fs.exists(confPath, function (exists) {
      var readPath = p.join(__dirname, '/config.json');
      
      if (exists)
        readPath = path;
        
      fs.readFile(readPath, 'utf8', function(err, buf) {
      
        fs.writeFile(path, buf, function() {
        
          map = JSON.parse(buf);
          cb(err);
        });      
      });
    });
  },

  save: function(cb) {

    fs.writeFile(path, JSON.stringify(map), cb);
  },

  get: function() {

    return map;
  }

};
