please wait docs and apidoc.

JSDM
====

Domain development , DDD-CRS framework for node.js and browser's component/component framework .

Node.js Install
==================

npm install jsdm

Component Install
====================

component install brighthas/jsdm


domain mean?
============

domain is a black box , outside operate must use domain.exec function.

domain inside include Aggre, EventHandle, Service and CommandHandle.

domain.exec ---> command handle ---> serivce / Aggre object (generate events) ---> event handle


step 1. define Aggre
=====================

``javascript

// User.js

module.exports = wrap;

function wrap(my){

function User(name){
this._name = name;
}

User.prototype = {
getName:function(){
return this._name;
},
changeName:function(name){
this._name = name;
my.publish("user."+this.id+".changeName",name);
my.publish("user.*.changeName",this.id,name);
}
}
User.className = "User";
return User;
}



`

step 2. define user repository
==============================

`javascript

// user_repo.js
moduel.exports = wrap

// define aggre repository
function wrap(my){

var repository = new Repository("User");
var User = Aggres.User;

// repository is Repository instance , must implement _create/_data2aggre/_aggre2data
repository._create = function(data,callback){
var user = new User(data.name);
callback(undefined,user);
}

repository._data2aggre = function(data){
var user = new User(data.name);
user.id = data.id;
return user;
}

repository._aggre2data = function(aggre){
var data = {
name:aggre.getName(),
id:aggre.id
}
return data;
}

return repository;

}

`
step 3. define command handle
==============================

`javascript

// handle.js

function wrap(my){

// define command handle 1
function handle1(args,callback){
var repo = my.repos.user;
repo.get(args.id,function(err,user){
user.changeName(args.name);
callback();
})
}
handle1.commandName = "change user name";

// define command handle 2
function handle2(args,callback){
var repo = my.repos.user;
repo.create({name:args.name},callback)
}
handle2.commandName = "create a user";

return [handle1,handle2];

}

module.exports = wrap;

`

step 4. register and run
==========================

`javascript

var domain = require("jsdm")();
var UserClass = require("./User"),
user_repo = require("./user_repo"),
handles = require("./handle");

domain.register("AggreClass",UserClass)
.register("repository",user_repo)
.register("commandHandle",handles)
.seal();

domain.exec("create a user",{name:"bright.has"},function(){
console.log("lol")
})

`
domain.register
================
`javascript
domain.register("AggreClass",UserClass)
.register("repository",user_repo)
.register("commandHandle",handles)
.seal();
`
or
`javascript
domain.register("AggreClass",UserClass,"repository",user_repo,"commandHandle",handles)
.seal();
