What this IS about
▪ IBM® Notes/Domino® as the ultimate CMS
▪ Building Responsive Hybrid Websites & Mobile Apps
▪ Real live implementations of a few Frameworks/Libraries
▪ Lessons learned
▪ A free Notes CMS database for you to experiment with 
Let's have a quick look at it

The Domino 'Stack'
▪ IBM Notes & Domino is a cool 'Stack'
– Powerful (no-SQL) database
– Top-notch security
– Domino Access Service (DAS) for RESTful interfaces
– Flexible development platform
– Great Notes Client
– Proven and out of the box solution (but not free vs open source solutions)

HTML5 / CSS3 Development
▪ HTML5 is stable, powerful and broadly supported
▪ CSS3 is very flexible
▪ Mobile apps are easy to create and test
– Android Chrome & iOS Safari remote debugging is a godsend
– Chrome's Device Mode is brilliant
▪ Off line use of your apps is possible using Manifest & localStorage
▪ Turning HTML5 websites into Apps is possible
– e.g. PhoneGap or Appcelerator Titanium

What's a Framework / Library
▪ My Definition: 
Any set of CSS and/or JS code 
that do the dirty work for you
– Deal with cross-browser issues
– Responsive & mobile first design in mind
– Reusable components
– HTML - design - code - navigation - data
UI
Architecture
DOM▪ Layered schema:
– UI - Architecture - DOM
– Design - MVC - Supporting libs

Requirements
▪ Frameworks
– As much tailored to your (current) needs
as possible
– Well documented
– Well maintained
– Broadly used
– If MVC: REST support 
see John Dalsgaard REST services
▪ Your Skills
– HTML(5)
– CSS(3)
– JavaScript
– REST / JSON
– Notes:
– Formula language
– LotusScript
– XPages
– Domino Access Service

Bootstrap
▪ A Front-End framework 
Bootstrap is a free collection of tools for creating websites and web applications. 
It contains HTML and CSS-based design templates for grids, typography, forms, buttons, 
navigation and other interface components, as well as optional JavaScript extensions
▪ Examples & Demo:
– Countries
– EY: Topics
– Engage: website
▪ Screenshots and HTML
▪ The Good & the Bad

Bootstrap: the good and the bad
▪ The Bad
– Broadly used
– Not an MVC model: only UI
▪ The Good
– August 2010: Twitter released Bootstrap
as open source.
– GitHub: over 75,000 stars 
and more than 28,000 forks
– Regular updates: current version 3.3.2
– Many interface components
– Excellent documentation, and many
templates
– Easy to get started and implement
– Broadly used ▪ Tip: Bootstrap for XPages

Ratchet.js
▪ A Front-End framework 
Ratchet.js is used to build mobile apps with simple HTML‚ CSS‚ and JS components
– Countries

▪ Why I changed my mind!
▪ Screenshots and HTML
▪ Ratchet.js goratchet.com

Ratchet.js: Basic HTML (Part 1)
<!DOCTYPE HTML><html>
<head>
<title>ConnectED 2015</title>

<link href="/mydb.nsf/css/ratchet.min.css" rel="stylesheet">

<script src="/mydb.nsf/js/ratchet.min.js"></script>

</a>
<a class="tab-item" href="countries">
<span class="icon icon-list"></span><span class="tab-label">Countries</span>
</a>
</nav>
</body>
</html>

Ratchet.js: the good and the bad
▪ The Good
– Easy to implement
– Separate themes for Android and
iOS
– All basic mobile User Interface
components
– Nice documentation
▪ The Bad
– Relatively young (early 2013)
– Limited number of supported
browsers 
- Android: default and Chrome 
- iOS: Safari
– Only touch support: difficult to test in
desktop browsers
– Intercepts links
– Not an MVC model: only UI

Backbone.js
▪ A JavaScript library 
Backbone.js is a JavaScript library with a RESTful JSON interface 
and is based on the model–view–presenter (MVP) application design paradigm 
(MVP is a derivative of the model–view–controller (MVC))
– Countries
– A major Navy: mSurvey
▪ Why I changed my mind!
▪ Screenshots, Code and HTML
▪ Backbone.js backbonejs.org

Backbone.js: Code (Part 1)
// MODEL
var Country = Backbone.Model;
// COLLECTION
var CountryCollection = Backbone.Collection.extend({
model: Country,
url: '../api/data/collections/name/countries?count=300' //use a view via DAS
});

//VIEW
var CountryView = Backbone.View.extend ({
el: '#countrydiv',
template: _.template($('#country-template').html()),
initialize: function () {
countryList.fetch({ //fetch the data
success: function() { //if successful, render them in the DOM
countryView.render(); }
})
},
render: function () { //render the countries using the template
this.$el.html(this.template({countries: countryList.models}));
return this; }
});

// RUN IT
var countryList = new CountryCollection(); //create the collection
var countryView = new CountryView(); //create the view

Backbone.js: HTML (Part 4)

<div id="#countrydiv></div>

<script type="text/template" id="country-template">
<div class="table-responsive">
<table class="table table-striped">
<thead><tr><th>Country</th><th>Capital</th></tr></thead>
<tbody>
<% _.each(countries, function(Country) { %>
<tr>
<td><%= Country.get("country") %></td>
<td><%= Country.get("capital") %></td>
</tr>
<% }); %>
</tbody></table></div>
</script>

Backbone.js: the good and the bad
▪ The Good
– Good documentation
– Tiny in size (<7 kb)
– Nice integration with Underscore.js, 
especially for templates
– Routing is easy
– Widely used
– REST support
▪ The Bad
– Totally different concept
– Steeper learning curve
– Decent knowledge of JS required
– No data binding
– MVC model only: no UI

Knockout.js
▪ A JavaScript Framework 
Knockout is a standalone JavaScript implementation of the Model-View-ViewModel pattern 
with templates. The underlying principles are therefore: 
• a clear separation between domain data, view components and data to be displayed 
• the presence of a clearly defined layer of specialized code 
to manage the relationships between the view components

– mSurvey
– Wine Tasting CRUD

Knockout.js: Country Code VMMV (Part 1)
function AppViewModel() { 
var self = this; 
self.countries = ko.observableArray([]); //create empty observable Array 
 
$.getJSON("../GetCountries?openagent", function(data) { //get JSON of all countries 
self.countries(data); 
}); 
self.continents = ... //removed the code to get the unique list of continents from the countries 
self.filteredCountries = function(cont) { //function to get countries for 1 continent only 
return ko.utils.arrayFilter(self.countries(), function(country) { 
return (country.continent === cont); 
}); 
}; 
} 
ko.applyBindings(new AppViewModel());

Knockout.js: Country Code HTML (Part 2)

<div class="tab-content"
data-bind="template: { name: 'continent-template', foreach: continents }">
</div>

Knockout.js: Country Code Templates (Part 3)
<script type="text/html" id="continent-template"> 
<div class="table-responsive"> 
<table class="table table-striped table-condensed"> 
<thead><tr><th>Country</th><th>Capital</th></tr></thead> 
<tbody data-bind="template: { name: 'country-template',
foreach: $root.filteredCountries($data) }">
</tbody> 
</table> 
</div> 
</script>
 
<script type="text/html" id="country-template"> 
<tr>
<td data-bind="text: country"></td><td data-bind="text: capital"></td>
</tr> 
</script>

Knockout.js: Tasting Code
//trigger an AJAX request to get tastings when the main country selection changes 
self.maincountry.subscribe( function(newValue) { 
$.getJSON('../api/data/collections/name/tastings?count=50&keys=' + newValue,
function(data) { 
var mappedTastings = $.map(data, function(item) { return new Tasting(item); }); 
self.tastings(mappedTastings); 
}); 
});
//part of Saving Code: existing record, so update it (use patch, not post!) 
self.saveTasting = function () {
$.ajax(thistasting.updatelink.href, { 
data: ko.toJSON(thistasting),  
type: "patch", contentType: "application/json", 
success: function(result) { void(0); } 
});}
};

Knockout.js: the good and the bad

and almost 1,000 forks
– Good documentation and 
Interactive tutorials
– Data binding (including attributes)
– Automatic UI refresh
