About the demo app
The Demo app is built with
– AngularJS
– Bootstrap
– IBM Domino data
– Zero XPages
And to make it better
– A Bootstrap theme from Bootswatch.com (‘United’)
– Font Awesome for icons
– Animate.css for animations
– FastClick.js for a snappier UI
– angular-local-storage for local storage
Sessions data from the Totally Unofficial Totally Unsupported session database
INTRODUCTION TO MVC / REST ARCHITECTURE
Introduction to MVC / REST Architecture
• MVC (Model-View-Controller) is an architectural design pattern that encourages improved application organization through a separation of concerns.
– The Model manages the data
– The View is the HTML representation of the data through the use of Templates
• What your users see
– The Controller is the application code which is used to determine the way the Model is populated and displayed.
• Glues the Model and View together
• Angular provides the framework to do client-side MVC
Introduction to MVC / REST Architecture
• Representational state transfer (REST) is an architecture style for designing networked applications
– Uses simple HTTP calls
– JSON
• Performant
• Scalable
• Simple interface
• Portable
ServerClient
Introduction to MVC / REST Architecture
• We’ve been building web apps like this
Request page
- process request
- get data
- create HTML
Response
• HTML
• CSS
• JavaScript(display)
Client

• But this is getting popular
Webserver

Response
(static HTML, JS,
CSS)

APIData (JSON)

INTRODUCTION TO ANGULAR.JS
AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. Angular's data binding and dependency injection eliminate much of the code you currently have to write.
“Angular is what HTML would have been had it been designed for applications”
The AngularJS team
What is AngularJS
• Web application framework
– Designed as a boilerplate model for an application
– Out of the box capabilities and best practices
– Built with test driven development (TDD) in mind
• Runs in the browser, all client side JavaScript
– Unlike e.g. XPages or C# (SharePoint) where most processing is done server side.
• Helps to create dynamic sites / Single Page Applications
– Partials? Dynamic? Been there, done that!
Why AngularJS ?
• Large developer community
– ~75,000 questions tagged on Stackoverflow.com
• Backed by
– Developed by Google and the community
– Open source (MIT license)
• Stable, mature and performant
– Initial release 2009
– Version 1 released Jun 2012
– Current version 1.3.5 (Dec 2014)
– Version 2 scheduled for end of 2015
Why AngularJS?
• Ready for the web of tomorrow
• Many Concepts adopted by Web Components standard
• Data driven
• Custom elements (functional custom attributes)
• HTML Imports
• DOM Templating
AngularJS: Modules
• Ties the code to the HTML DOM model
Angular Route Control
• UI-Router, state based management
• Configures the app
• When a route is encountered
– Use this template
– Use this Page Title
– Use this controller
• http://beyondtheeveryday.com/#/sessionsAll
• http://beyondtheeveryday.com/#/favorites
AngularJS: Controllers
• Contains the application logic.
app.controller("MainCtrl", function($rootScope, $scope, utils,
localStorageService, SessionsFactory) {
$scope.menuDays = [
{id: '0', label:'Sunday'},
{id: '1', label:'Monday'},
{id: '2', label:'Tuesday'},
{id: '3', label:'Wednesday'}
];
//set default active menu option
$scope.pageTitle = "Connect 2015 Sessions";
$scope.activeMenu = "about";
• Lazily instantiated, only when they are needed
– “Angular services are substitutable objects that are wired together using dependency injection (DI). You can use services to organize and share code across your app”
var app = angular.module("sessionsApp.services", []);
app.factory('SessionsFactory', function($http) {
return {
all : function() {
return $http.get(‘db.nsf/collections/name/sessions')
.then(
function(res) {
return res.data;
});
},
...
AngularJS: Factories and Services
AngularJS: Directives
• Tells Angular that it needs to ‘do’ something
• Interact with the browser based on the controller’s instructions
• Re-usable components
• Much of Angular’s core functionality Directive based
<div class="row" ng-repeat="speaker in session.speakers">
<div class="col-xs-12 col-sm-12">
{{speaker}}
</div>
</div>
AngularJS in depth
• Dependency injections
A software design pattern that deals with how components get hold of their dependencies.
The Angular injector subsystem is in charge of creating components, resolving their dependencies, and providing them to other components as requested.
AngularJS in depth
• How does it all hang together?
AngularJS in depth
• AngularJS core examples
– ‘$scope’
sessionsAppCtrl.controller('FeedbackCtrl', function($scope, SessionsFactory) {
$scope.submitted = false;
$scope.submit = function() {
SessionsFactory.saveFeedback( {feedback : $scope.feedback, name: $scope.name} );
$scope.submitted = true;
};
});
AngularJS in depth
• AngularJS core services example
– '$http'
app.factory('SessionsFactory', function($http, $q, dasBaseUrl, utils) {
return {
all : function() {
return $http.get('collections/name/sessionsAll?count=1000', {cache: true})
.then( function(res) {
return res.data;
});
},
...
AngularJS in depth
• AngularJS core directives examples
– ng-show / ng-hide
– ng-click
– ng-list, ng-class, ng-repeat, ng-keydown etc
};
<div class="col-sm-8">
<button class="btn btn-default" ng-click="home()">Back</button>
<button class="btn" ng-click="savePerson($event)" ng-hide="create">Save</button>
<button class="btn" ng-click="createPerson($event)" ng-show="create">Create</button>
</div>
AngularJS in depth
• AngularJS template example
AngularJS in depth
• How does AngularJS integrate with XPages ?
• An application written using AngularJS uses 4 main things
– HTML Pages
– JavaScript files
– CSS
– A Data Service
• One or many of those can be “XPages”
DOMINO AS A REST SERVICE
Domino as REST service
• Three options to use Domino as a data store for an Angular application:
– Domino Access Services
• Built-in, easiest to enable
– REST service component from the Extension Library
• More customization options
– Do-it-yourself REST service
• Fully customizable, requires more work
Domino as REST service - Domino Access Services (DAS)
• Consists of 3 services: core, data and calendar
– For the demo app we’ve only used the data service
• Must be enabled on server level, app level and form/ view level
• Gives you the data from all fields (documents) or columns (views)
Domino as REST service - Domino Access Services (DAS)
http://beyondtheeveryday.com/beyond/connect2015.nsf/api/data/collections/name/sessionsAll
Server Database path DAS View name
Domino as REST service - ExtLib REST
• Drag on an XPage
• Link to data source (view, bean, …)
• Set path
• Done
<xe:restService pathInfo="contactjson">
<xe:this.service>
<xe:viewJsonService viewName="AllContacts" var="entry"
contentType="text/plain" count="10" defaultColumns="true">
</xe:viewJsonService>
</xe:this.service>
</xe:restService>
Domino as REST service - custom REST service
public class MyRESTService {
public static String doGet(HttpServletRequest request, HttpServletResponse response)
{
JsonJavaObject json = new JsonJavaObject();
json.put("userName", ExtLibUtil.getCurrentSession().getEffectiveUserName() );
return JsonGenerator.toJson(JsonJavaFactory.instanceEx, json);
}
}
<!--?xml version="1.0" encoding="UTF-8"?-->
<![CDATA[#{javascript:
var externalContext = facesContext.getExternalContext();
var writer = facesContext.getResponseWriter();
writer.write(
eu.linqed.MyRESTService.doGet(
externalContext.getRequest(),externalContext.getResponse()
));
writer.endDocument();
}
}]]>
