App installation
The angular-seed project can be used to create core project components.
Update bower.json to add front-end frameworks to the seed project, e.g. with Twitter Bootstrap.
In the tutorial stub data was added as JSON files in app/phones/.
AngularJS installation
npm and bower
bower can be used to install the Angular framework.
CDN
CDN: //ajax.googleapis.com/ajax/libs/angularjs/1.5.0-beta.2/angular.min.js
Click Download on the AngularJS landing page. On the next page all the distributions are listed.
Project dependencies
Project dependencies can be managed with npm. All project dependencies are stored in package.json in the project root.
E.g. karma is a unit testing package. Install with npm install karma --save-dev.
Then in order to update another distribution of the web app, npm install on the new server.
The AngularJS tutorial uses bower to install the AngularJS framework. So, npm install installs bower, which is then in turn used to install angular, bootstrap, and jquery packages in app/bower_components/
Using Angular
Templates are located in app folders, e.g. if the app is myapp/, the template can be myapp/index.html.
Define "root scope" with the ng-app attribute, e.g.
<html lang="en" ng-app="myappApp" class="ng-scope">
Define a controller's scope with ng-controller, e.g.
<body ng-controller="MyListCtrl" class="ng-scope">
Object properties are inserted into a template with double curly braces, e.g. Template:Myobj.name
Controller logic is located in myapp/js/controllers.js. Fore the examples above the controller logic might look like this:
var myappApp = angular.module('myappApp', []);
myappApp.controller('MyListCtrl', function($scope) {
/* retrieve data here */
});
Testing Angular
Unit tests
Unit tests are performed using karma using Jasmine's behavior-driven development (BDD) syntax.
describe('PhoneListCtrl', function(){
beforeEach(module('phonecatApp'));
it('should create "phones" model with 3 phones', inject(function($controller) {
var scope = {},
ctrl = $controller('PhoneListCtrl', {$scope:scope});
expect(scope.phones.length).toBe(3);
}));
});
Run unit tests with `npm test` from the project root directory.
This will launch a process that continues to run. Tests will be re-run each time any source file is saved.
