My Alter Ego
Agenda• Overview• Application Architecture• User Experience• Optimization• Closing
Overview
“A developer in today’s world needs to look both ways before crossing a one-way street.”
- Doug Linder
Overview• A reality most developers are facing is that businesses are
moving to the Cloud• This means:
Applications need to be Cloud ready APIs, APIs, APIs Modular Services Mobile strategy. No exceptions Optimized user experience and application performance
Application Architecture
Application Architecture• Single Page Application
One entry point to your Application• One URL
One XPage. Many custom controls
Application Architecture• Single Page Application cont.
Advantages:• Full page reloading no longer required
• Actions can have as little as one server request
• Request and response data can be measured in bytes
• Core CSS/JS resources are loaded once
Application Architecture• Single Page Application cont.
Disadvantages:• JavaScript dependency
• Optimization is essential
• Knowledge of 3rd party UI libraries a must
• Single entry point to application makes navigating a bit more complex
Demonstration
Application Architecture• OpenNTF Domino API
Extends Domino Object Classes• Additional methods and properties
• Improved code
Quick to install and configure• This also applies to existing XPages applications
No need to recycle Domino Objects in Java Multi-threaded processing
Application Architecture• Model View Controller Strategy
Model• A Java class for each document type
• Define field names as class properties
• Use a constructor to default property values
• Generate getters and setters for each property
Application Architecture
Application Architecture• Model View Controller Strategy cont.
View • XPage or Custom Control
• Should only contain HTML and XML tags where possible
• Styling exists mostly in style sheets
• Logic exists in JavaScript files or Java classes– i.e. Controllers
Application Architecture• Model View Controller Strategy cont.
Controller• A Java class for each document type
• Manages all logic related to its Model and View– Validating content
– Saving data
– Fetching data
– Special functions
Application Architecture• Model View Controller Strategy cont.
A Controller should exist for each of the following:• The application as a whole (e.g. Global Controller)
• For the user’s session (e.g. Session Controller)
• For each document type that can be submitted or viewed
• For each primary feature of your application:– Report Controller
– API Controller
– User Controller
Application Architecture
Demonstration
Application Architecture• XPages Extension Library
A plethora of additional controls Application Layout for rapid UI design Twitter Bootstrap and jQuery enablement
• If enabled, your UI is automatically bootstrapped and responsive
Application Architecture• XAgents
A XPage that does not render a user interface but executes logic and returns data as a result
• Accessed via a URL with optional parameters (aka Web Service)
Expose your XPages application through APIs• For mobile apps
• 3rd party platforms and applications
Run scheduled Java agents that execute XPages logic
Application Architecture• XAgents cont.
Example XPage acting as an XAgent:
Application Architecture• XAgents cont.
Example scheduled Java agent executing XAgent:
User Experience
User Experience• Twitter Bootstrap
HTML, CSS and JavaScript framework for developing responsive applications
Intelligent styling that re-adjusts web page based on device’s form factor
• Laptops/Desktops
• Smartphones
• Tablet devices
Modern UI controls Offered as part of the XPages Extension Library
User Experience• 3rd Party Libraries
Animate.css – Provides animations to your XPages controls Toastr – Provides non-blocking notifications Font Awesome – A collection of vector icons that are easily
customizable:• Grouping
• Sizing
• Animating
Sweet Alert – Provides animated alert notifications
Demonstration
Optimization
“A developer achieves perfection not when there is nothing more to add, but when there’s nothing more to take away”
- Antoine de Saint-Exupery
Optimization• Multi-threaded Operations
Powered by ODA XOTS Execution of logic in its own thread that user does not depend on:
• i.e. Asynchronous operations in Java code
Allows for quicker response times when performing server side operations
Especially important for Web Services accessed by mobile apps
Optimization• Switch and Dynamic Content Controls
Divide web page into HTML blocks that are rendered/removed when relevant
This means:• Only populate the HTML you need
• Hidden HTML is not rendered to the browser until it’s required
• Less HTML for jQuery/Dojo to work through
• Web page is lightweight
Demonstration
