Are you starting a new XPages project, but not sure it’s going to be done right the first time? Do you have an existing application that doesn’t seem to have that “X” Factor? In this webinar, John Jardin demonstrates how XPages developers can apply proven techniques and best practices to take their applications to a game-changing level.

You'll learn how to:
-Rapidly develop responsive applications,
-Improve user experience and response times with background and multi-threaded operations,
-Keep your XPages lightweight with code injection,
-Create scheduled tasks the XPages way,
-And much more.

  16. 16. My Alter Ego
  17. 17. Agenda • Overview • Application Architecture • User Experience • Optimization • Closing
  18. 18. Overview
  19. 19. “A developer in today’s world needs to look both ways before crossing a one- way street.” - Doug Linder
  20. 20. 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
  21. 21. Application Architecture
  22. 22. Application Architecture • Single Page Application  One entry point to your Application • One URL  One XPage. Many custom controls
  23. 23. 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
  24. 24. 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
  25. 25. Demonstration
  26. 26. 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
  27. 27. 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
  28. 28. Application Architecture
  29. 29. 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
  30. 30. 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
  31. 31. 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
  32. 32. Application Architecture
  33. 33. Demonstration
  34. 34. 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
  35. 35. 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
  36. 36. Application Architecture • XAgents cont.  Example XPage acting as an XAgent:
  37. 37. Application Architecture • XAgents cont.  Example scheduled Java agent executing XAgent:
  38. 38. User Experience
  39. 39. 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
  40. 40. 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
  41. 41. Demonstration
  42. 42. Optimization
  43. 43. “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
  44. 44. 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
  45. 45. 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
  46. 46. Demonstration
