Superheroic JavaScript MVW Framework

"Angularjs is what HTML would have been, had it been designed for building web-apps"

AngularJS?


!= library


= Framework

"Better Browser"



S.P.A.


Single Page Applications


Filosofie

  • Dynamische websites/webapplicaties
  • DOM manipulatie != Application Logic
  • Extend HTML
  • Declaratieve templates met databinding
  • Modulair
  • Testbaar
  • Plain Javascript

    Stabiel


    Minder vaak updates dan bijvoorbeeld JQuery

    Stabiele release en unstable release

    Unstable != Unstable 
    nieuwe features die nog gewijzigd kunnen worden.

    Buzz ?

     "When you develop in Angular, you are  developing in a better browser!" 

     "Angular is what the web browser would have been, had it  been  designed for applications" 


     "Pretty sure that HTML6 is going under the codename  @angularjs!"

     Build with AngularJS 

    Forget everything you know











    About JQuery

     

    Seriously !!!

     

    Forget JQuery

    JQuery zonden

    1. Don't Design Your Page, then Change it with DOM Manipulations
    2. Don't Augment JQuery with AngularJS
    3. Always Think in Terms of Architecture
      • The View is the "Official Record"
      • Databinding
      • Distinct Model Layer
      • Seperation of concerns
      • Dependency Injection
    4. Test Driven development


    Imperative VS Declarative


    Hoe VS Wat

    JQuery VS AngularJS



    <input id="toggleShowHide" type="checkbox">
<div id=”specialParagraph”>
    This content will disappear and reappear if you click the checkbox above
</div>

    <script>$(function() {
     function toggle() {             var isChecked = $('#toggleShowHide').is(':checked');
          var specialParagraph = $('#specialParagraph');
                if (isChecked) { specialParagraph.show(); }             else { specialParagraph.hide();  }        }
            $('#toggleShowHide').change(function() {
                toggle();
            });
            toggle();
        });
    </script>

    AngularJS


    <input ng-model="showSpecial" type="checkbox">
<div ng-show=”showSpecial”>
    This content will disappear and reappear if you click the   checkbox above
</div>

    Don't include JQuery



    DOM manipulatie


    Wil je per se een JQuery plugin oid gebruiker. 
    Doe dit dan binnen een Directive 

    MAAR:
    "Conceptually, Directives are NOT packaged JQuery"

    9/10 x bereik je hetzelfde resultaat met minder code wanneer je het gewoon in AngularJS schrijft.
     



    Applicatiestructuur



    Module

    Vaak eerst één module per app.

     angular.module('ggdodApp', []);


    Module per feature

    • Gebruikers beheer
    • Dossier
    • Planning
    • Zorgpaden
    • Product beheer


    Angular Modules


  • angular.js
  • angular-animate
  • angular-route
  • angular-resource
  • angular-sanitize
  • angular-touch
    • angular.module('ggdodApp', ['ngAnimate', 'ngRoute', 'ngResource']);


    Config

    app.js
    angular.module('ggdodApp', []);
    index.html
    <!DOCTYPE HTML>
<html ng-app="ggdodApp">
<head>  <title>Gino Draait Door op Dinsdag </title></head><body>  <h1> Dit Gino Draait Door op Dinsdag</h1><script src="scripts/vendor/angular/angular.min.js">
    <script src="scripts/app.js"></script>
    </body></html>

    View



    HTML

    Templates

    !! Declaratief !!

    $scope

    $scope.person = {
          firstName: 'Jan'      lastName: 'Progger' }
    controller.js
    <h1> {{ person.firstname }} </h1>
    template.html

    Controller

    scripts/controllers/main.js
    "Expose model objects and methods to the View"

    • View specifieke code
    • GEEN DOM manipulatie
    angular.module('ggdodApp')
  .controller('MainCtrl', function ($scope) {
     $scope.person = {
        firstName: 'Jan'
        lastName: 'Progger' 
     }
  });

    Controller as >= 1.2

    views/main.html
    <div ng-controller="MainCtrl as main">    <p> {{ main.person.firstname }} {{ main.person.firstname }} </p></div>
    scripts/controllers/main.js
     angular.module('ggdodApp')
  .controller('MainCtrl', function () {

         this.person = {
        firstName: 'Jan'
        lastName: 'Progger' 
     }
  });

    Plunker: Controllers

    Routing

    • Deep Linking
    • History (back button)

    angular.module('ggdodApp', ['ngRoute'])
  .config(function ($routeProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'views/main.html',
        controller: 'MainCtrl'
      })      .when('/person/:name', {
        templateUrl: 'views/person.html',
        controller: 'PersonCtrl'
      })
      .otherwise({
        redirectTo: '/'
      });
  });

    Services

    • View independent methods
    • Singleton

    • Constant
    • Decorator
    • Factory
    • Provider
    • Service
    • Value

    Factory

    scripts/services/person.js
    angular.module('ggdodApp').factory('Person', function(){  var personFactory = {};  var person = {                  firstName: 'Jan',                 lastName: 'Progger                }  personFactory.get = function(){     return person;  }  return personFactory;
    });

    Constant


    scripts/services/constants.js
    angular.module('ggdodApp').constant('BEDRIJF', 'Gino B.V.');
    angular.module('ggdodApp').constant('ANSWER', 42);
    scripts/controllers/main.js
    angular.module('ggdodApp').controller('MainCtrl',                               function(BEDRIJF, ANSWER){     console.log('Bedrijf is ' + BEDRIJF);     console.log('The all knowing answer is: ' + ANSWER);}

    Directory structuur

    • /images
    • /scripts
      • /controllers
      • /directives
      • /services
      • app.js
    • /styles
    • /views
      • main.html
