History of web applications

How about the 'Jquery way'

AngularJS

Here to save your Day

Offical Site

angularjs.org

Killer Features

Two-way binding

 

Declarative coding for UI

 

Separation of model & view,No DOM manipulation, less code

 

Great for CRUD based single page apps

 

Awesome adoption and great community

 

Unit testable

 

 

 

 

MVC

Model

View

Controller

Module

Package the building pieces of the application


Acts as containers


Can be more than one module 

   

 

 angular.module('SLIITModule',[])

Scope & Controller

Learnings

Controller objects can separate data and functionality


There can be many controllers


$scope.data in the controller is referred to as simply data in html

 

Dot notation for object members works (person.age)
 

Dependency Injection

"Dependency injection is a software design pattern that allows the removal of hard-coded dependencies and makes it possible to change them, whether at run-time or compile-time."

 

angular.module('SLIITWorkshop', ['socketioModule'])

Directive

 A function that executes when the Angular compiler finds it in the DOM

<body>
<my-awesome-site></my-awesome-site>
</body>
app.directive(‘myDirective', function() {
return {
restrict: 'AEC',
replace: true,
template: '<p style="color: {{color}}">Hello World</p>',
link: function(scope, elem, attrs) {
…
},
compile: function(tElem,attrs) {
…
}
};
});

ngDirectives

ng-show/ng-hide

 

ng-click

 

ng-repeat

 

ng-if

 

Services

Singleton objects that are instantiated only once per application

 

Share data and behavior among controllers,directives,filters and other services.

 

 

 

Constant

Used for registering a service such as constant,string,

array,object or function.

 

Cannot have dependency.

 


 

 

 

 

angular.module('configuration', [])
    .constant('Digin_Extended_Analytics','http://104.236.192.147:8281')

Configurations

Run Blocks

 

 


 

 

 

 

var myApp = angular.module('myApp', ['ui.router','facebook'])
    .config(function($stateProvider, $urlRouterProvider, FacebookProvider){
        $urlRouterProvider.otherwise("/state1");
        $stateProvider
          .state('state1',{
            url: 'state1',
            templateUrl: "../pages/form.html"
          });
          $locationProvider.html5Mode(false);

        var myAppId = '<FB app id>';
            FacebookProvider.init(myAppId);
    });

Templating and Routing

Single page application

 

Load different views contained in partial html files based on address bar location and apply specific controllers

Templating and Routing

Do's in an Angular App

Organizing your code

 

Scope madness

 

Communication between components

 

Unit testing

Packaging Application
