AngularJS for Web and Mobile
Michael Byrne, MV Product Evangelist

Abstract
 Learn about the fundamentals of AngularJS and how it can help you
quickly build powerful web and mobile applications. This session will
explore why AngularJS is a good choice for a front-end framework and
demonstrate some of the power it gives you. Note: this will focus mostly on
new technology and only briefly on how it integrates with MultiValue.

7
What is AngularJS?
Open-source web application framework maintained by
Google and a community of developers
Front-end JavaScript framework
• JavaScript is the programming language of HTML and the web
• Simplifies development and testing of web applications
• Provides Model-View-Controller (MVC) framework
Custom tag Attributes interpreted at run-time
<input id="txtFirstName" ng-model="firstName" />

8
AngularJS Usage
AngularJS is used on the websites of NBC,
Walgreens, Intel, Sprint, and approximately 7,000
other sites
As of July 2015, current stable version 1.4.2
Several changes coming with version 2

AngularJS Alternatives
• Makes no assumption about
technology stack, just UI
• Virtual DOM
• One-way data flow
• Auto-updating handlebars
templates
• Create custom components
• Simple routing
• Universal JavaScript,
client and server
• Websocket microservices
• Integrates with AngularJS or
ReactJS

Common Terms and Concepts

12
<!DOCTYPE html>
<html ng-app="tasklist">
<head>…</head>
<body ng-controller="MainCtrl">
<h1>{{ appTitle }}</h1>
<button ng-click="getTasks()">Tasks</button>
<table>
<tr ng-repeat="task in tasks">
<td>{{ task.desc }}</td>
<td>{{ task.notes }}</td>
</tr>
</table>
var app = angular.module('tasklist', []);
app.controller('MainCtrl', function($scope) {
$scope.appTitle = 'MVU Task List';
$scope.getTasks = function() {
$scope.tasks = [
{ desc:"Task 1", notes:"More info" },
{ desc:"Task 2", notes:"" }
]
};
};
Directives
A directive is a marker on a HTML tag that tells Angular to
run or reference some JavaScript code
Custom directives can be new HTML elements/attributes
Model/Controller (Javascript) View (HTML/Template)

13
Custom Directives
app.directive('myDirective', function () {
return {
restrict: 'E', // Element, Attribute, Class, Comment
link: function ($scope, element, attrs) {
element.bind('click', function () {
element.html('You clicked me!');
});
element.bind('mouseenter', function () {
element.css('background-color', 'yellow');
});
element.bind('mouseleave', function () {
element.css('background-color', 'white');
});
}
};
});
<my-directive>Click Me!</my-directive>

14
Modules
Where we write pieces of NG application
Defines dependencies between modules
Can use modules as component building blocks
<!DOCTYPE html>
<head>…</head>
<table>
</tr>
</table>
$scope.tasks = [
]
};
};

15
<!DOCTYPE html>
<head>…</head>
<table>
</tr>
</table>
$scope.tasks = [
]
};
};
Controllers
Where we control our app’s behavior by defining
functions and values

16
<!DOCTYPE html>
<head>…</head>
<table>
</tr>
</table>
$scope.tasks = [
]
};
};
Expressions
Allow you to insert dynamic values into your HTML

17
Data Binding
Angular utilizes 2-way data binding

18
Filters – Built-In
{{ '1234.5678' | currency }} $1234.00
{{ '1234.5678' | number:1 }} 1234.6
{{ 1288323623006 | date:'medium' }} Oct 28, 2010 9:40:23 PM
{{ 'Hello MVU' | lowercase }} hello mvu
{{ 'Hello MVU' | uppercase }} HELLO MVU
{{ 'abcdefghi' | limitTo:3 }} abc
<tr ng-repeat="friend in friends | orderBy:'-age'">

21
Dependency Injection
Software design pattern in which components are given
their dependencies rather than hard coding
Makes components reusable, maintainable, testable
NG handles the Dependency Injection Framework
https://en.wikipedia.org/wiki/Dependency_injection
app.controller('MainCtrl', function($scope, $http) {
$http.get('http://abc.com/api/items').
then(function (response) {
// Do something with response
};
};

22
Services
Substitutable objects that are wired together using
Dependency Injection (DI)
Several built-in services such as:
$http, $location, $log, $animate, etc.
Can create custom services

23
Developing an AngularJS App

24
Getting Started - Plunker
http://plnkr.co/
Online real-time editor
Templates for
frameworks like Angular
Collaboration
http://jsfiddle.net is
similar

25
Getting Started – Local Development
Download AngularJS (http://angularjs.org)
• We need angular.min.js
Download jQuery (https://jquery.com/download/)
• AngularJS has jQuery lite, but Bootstrap needs full jQuery
Download Twitter Bootstrap (http://getbootstrap.com)
• We need bootstrap.min.js

26
AngularJS Demo Application

27
Why Bootstrap?
Without Bootstrap With Bootstrap
+ Responsive
+ Animations
+ Customizable
+ Community

28
Let's Build the Demo!

29
Getting External Data
MV REST API
Web Server
MV Database

30
Example with MultiValue Data
Data from UniVerse
REST Server

31
Playing with MVU Plunker Demo
http://plnkr.co/edit/QjRho6
Click on Fork to make a copy for you to work with
Now you can make changes and save your versions
going forward

32
Debugging and Troubleshooting
Browser developer tools
Network activity
Source debugging
Console
Edit HTML and CSS

33
AngularJS for Mobile
Already great for Single Page Applications (SPAs)
Bootstrap gives responsive design
Third party Mobile Angular UI

34
What’s Coming in Version 2

35
AngularJS Version 2
Rewrite of the entire framework
Driven by mobile, modularity, and keeping modern
Uses AtScript, which is a superset of EcmaScript6
• Compiled to generate ES5 code
Annotations, improved Dependency Injection (DI),
routing changes, etc.

38
Summary
AngularJS is great for organizing front-end code
Very powerful, but there is a bit of a learning curve
Can be used for web or mobile applications
