Reacting fast to user input
Providing comprehensive interactions
Using only one page?

// our awesome app

Let’s get into code
Intermediate Function Expression - iife
(function() { 'use strict';
// Isolation
})();
Why iife?
var greet = 'Hi!';
script.js
var greet = 'Bye!';
conflict.js
Last man standing
Why iife?
var greet = 'Hi!';
script.js
(function () { 'use strict';
})();
var greet = 'Bye!';
conflict.js
(function () { 'use strict';
})();SAVE
angular .module('app', [
'module', 'feature']);
Defining a module
// … Extend it with // other modules
// Name your module...
angular .module('app') .controller('Persons', Persons);
function Persons() { }
Defining a controller
angular .module('app') .directive('semanticHtml', semanticHtml);
function semanticHtml () { return { restrict : 'E | A | C', template : '<html-template>' };}
Our first directive
// Nearly the same like our // controller, right?
// Watch out!// Directives return a new // object literal
Even more about directives
function semanticHtml () { return { restrict : 'E | A | C', template : '<html-template>' templateUrl: scope: controller: link: };}
angular .module('app') .filter('manipulate', manipulate);
function manipulate() {
return function(input, /* parameters */ ) {
}}
Starting with filters
// Watch out!// Filters return a function.
There are many filters already implemented
https://github.com/a8m/angular-filter
angular .module('app') .factory('dataAccess', dataAccess);
function dataAccess() {
return {
};}
Defining a factory, service, whatever...
// LEGO bricks the angular// way
// Declaring the api of our// service
$injecting a service into a controller
// angular magic
angular .module('app') .controller('Persons', Persons);
Persons.$inject = ['dataAccess'];
function Persons(dataAccess) { }
angular .module('app') .controller('Persons', Persons);
function Persons(dataAccess) { }
$injecting a service into a controller
// still works without $inject
angular .module('app') .controller('Persons', p);
function p(a) { }
$injecting a service into a controller
// But a minifier will break// your app
a cannot be resolved as dataAccess
events
childcontroller
parent controller
$broadcast
$emit
$scope ('eventName');.$emit.$broadcast
events using $rootScope
controller subscriber
controller publisher
$rootScope .$emit('eventName');
$rootScope .$on('eventName' , callback);
