Angular.js egghead tutorial outline

1. create a service, which can be initialised from a node

var app = angular.module("myApp", [dependencies]);

2. app exists, create a controller, controlling a node and its children

app.controller("nameCtrl", function($scope){  //xxxCtrl is naming convention
   //$scope can have function and attributes in json favor
   $scope.content = {message:"I am content"}
   $scope.foo=function(){...}
})

3. app, controler exist, directive is customised node/attribute

app.directive("name",function(){
   return {
     restrict: "E || A || M",
     $scope{ 

        element/attr : "@ || & || = ", // @attr, &attr, =attr


     }, //isolated scope, used in multiple instances of the directive

     template: '
Here is returned inner html, can do {{bindModule or value}}
',

     link：function(scope,element,attrs,[depended controller])
                  {...} //like the constructor
     controller: function() {
        foo1 = function(){}
     } // an API controller that other directive will depend on
   }
})

app.directive("anotherName", function(){
    require : 'name'
    link: function(scope,element,attrs, nameCtrl){...can invoke nameCtrl foo1} //nameCtrl - naming convention
})
