Transformation of Legacy Logistics Application with Angular


This case study focuses on the transformation project undertaken by SC CODEWORKS to modernize their legacy logistics application. The legacy application managed critical aspects of warehouse operations, including order management, item tracking (including hazardous chemicals), tallying, warehouse locations, shipping, and consignee information. The application was built using RPG programming and relied on a conventional user interface (UI) based on function keys. To enhance usability and align with modern standards, SC CODEWORKS opted to reimagine the application using Angular, a popular web development framework known for its flexibility and modern UI capabilities.


The legacy logistics application faced several challenges, including:

  1. Outdated User Interface: The conventional UI based on function keys limited user interaction and lacked modern design aesthetics.
  2. Limited Flexibility: The existing application had rigid functionality, making it difficult to adapt to evolving business requirements.
  3. Usability Constraints: Users encountered difficulties in navigating the application and performing tasks efficiently due to outdated design patterns and limited user-friendliness.


To address the challenges, SC CODEWORKS decided to transform the legacy application using Angular, a modern web development framework. The key aspects of the solution include:

  1. Migration to Angular: The existing RPG-based application was rebuilt using Angular to leverage its flexibility and modern UI capabilities.
  2. Enhanced User Interface: The transformed application incorporated modern design patterns, intuitive navigation, and improved aesthetics, providing a user-friendly experience.
  3. Adaptability: The new application architecture and codebase allowed for easier modifications and updates, enabling the system to evolve alongside changing business requirements.
  4. Integration with Node.js: The backend of the application was developed using Node.js, ensuring seamless communication between the frontend and backend components.
  5. Database Integration: The application utilized IBM DB2 as the database system, enabling efficient storage and retrieval of logistics-related data.

Technologies Used:

The transformation project utilized the following technologies:

  • Frontend: Angular
  • Backend: Node.js
  • Database: IBM DB2

Benefits & Value Delivered:

The transformation of the legacy logistics application with Angular delivered several benefits and value to SC CODEWORKS and its users:

  1. Modernized User Experience: The new application provided a modern UI with improved aesthetics and user-friendly features, enhancing the overall user experience.
  2. Enhanced Functionality: The use of Angular enabled the addition of new features, customization options, and seamless integration with other systems, enhancing the application’s functionality.
  3. Flexibility and Adaptability: The transformed application allowed for easier modifications and updates, ensuring it could accommodate evolving business requirements and industry changes.
  4. Improved Productivity: The user-friendly interface and streamlined workflows resulted in increased productivity for logistics professionals, enabling them to perform tasks more efficiently.
  5. Optimized Warehouse Operations: The new application optimized warehouse operations through improved order management, item tracking, tallying, and shipping functionalities, leading to enhanced operational efficiency.


Through the transformation project leveraging Angular, SC CODEWORKS successfully modernized their legacy logistics application, delivering a user-friendly, flexible, and feature-rich platform for logistics operations. The utilization of Angular, along with Node.js and IBM DB2, provided a robust and scalable solution. The transformed application empowered logistics professionals with enhanced functionality, improved productivity, and the ability to adapt to changing business requirements. SC CODEWORKS achieved its goal of optimizing warehouse operations and delivering an enhanced user experience aligned with modern industry standards.
