Bank Albilad

Modernization to New Tech Stack

Current Technology Stack

  • Struts2 framework for backend MVC.
  • jQuery for DOM manipulation and AJAX calls.
  • Custom JavaScript for additional functionalities.
  • CSS for styling

What's the problem?

  • No reusability in CSS and JS
  • No state management among components and pages
  • Performance issues
  • hard to debug
  • Inconsistencies among UI elements
  • Repeatative work again and again

Our Goals

  • Enhance user experience
  • Easy code maintainability
  • leverage modern technology stack
  • Enhanced Performance  
  • Independent isolated Apps (Micro frontends) 

What we will achieve

  • More control over the UI 
  • Reusability of UI components (Headless UI)
  • Reusable business logic
  • Continuous evolving technologies 
  • Extensive support & huge community
  • Custom UI library for Bank Albilad theme
  • Use across all Apps (Code once use everywhere)
  • Uniform and consistent UI (Too many different UI elements) 
  • Based on Well tested UI frameworks 

Our own UI Library

(Design System)

Top UI Libraries

  • Material Design
  • Ant Design 
  • Material Design
  • Ant Design
  • Ant Design Mobile (For React Native)

Incremental Migration

Preparation:
Identify key functionalities of the existing app.
Document dependencies, APIs, and business logic.

Migration:

  • Incremental migration (piece by piece replacement) instead of big bang migration (complete rewrite)

  • Prioritize features/pages to migrate based on complexity and usage

  • Create a minimal React app and host it alongside the existing Struts2 app

 

Migration

  • Use iframe or subpath routing to embed new features/pages gradually

  • Identify reusable components and gradually build React versions of these components and replace jQuery

  • Ensure backward compatibility during the transition.

  • Document the new architecture, coding standards, and migration steps


    Subpath routing involves serving new React features/pages from specific paths within the existing app. For example, you can serve a React-based feature at bank.com/react-feature.

 

Add ons

  • Introducing GitHub/gitlab:
    • untouchable Master branch
    • Proper commit history and easy rollbacks
    • super quick & easy tracking of changes 
  • Unit testing:
    • Will save hours of debugging 
    • more maintainable code
