angoose/lib/Service.js

Angoose is a Remote Method Invocation module that comes with built-in mongoose/angular support. Now you can call server side module in browser just like you're in the server side!

var logger = require("log4js").getLogger("angoose");
var _ =require("underscore");
var Remotable = require("./Remotable")

// ## angoose.Service
// Service is one of two main artifacts in Angoose. Service classes are used to define business operations that 
// are not necessarily tied to database models.
// 
// To create an angoose Service, you just need to extend from this class:
//
//      var angoose = require("angoose");
//      var service = {
//          geoEncode: function(stringAddress){
//                  /** call google API */
//                  return coordinates
//          }    
//      }
//      module.export = angoose.service('GeoService', service);
//
// The Service class file must be located under one of the `modelDir` or `serviceDir` directories.
//
var serviceProto = {
    toJSON: function(){
        return {};
    }
}
var Service = Remotable.extend(serviceProto,{baseClass:'Service'});
