Logistic Control System Enhanced with Migration to Angular

User experience benefits from application improvements, making it more agile, intuitive, and responsive


The client, one of the world’s most important pharmaceutical industries, was grappling with challenges related to its logistics control application. The system in use had been internally developed using AngularJS, a technology that is no longer supported. Due to technological obsolescence, the application suffered from performance, security, and usability issues, impacting user experience and operational efficiency.


act digital was hired to carry out the migration of the system, developing it using the updated Angular technology. In the project, technologies such as Node.js, PostgreSQL, and Sequelize were also employed, enhancing the performance of database requests. User experience and performance were prioritized requirements, given the system’s relevance in the organization’s daily operations.


Technological migration improved the logistics control application, offering a better user experience. Usability and responsiveness were enhanced, favoring system usage on mobile devices (tablets and smartphones). Significant performance gains were achieved, reducing page loading time from 30 seconds to 1 second.

Developing internal systems is a strategic move for companies heavily involved in research and innovation. The customization of functionalities and data security justifies this choice. However, challenges need to be overcome, particularly ensuring that applications keep pace with technological changes and meet market, client, and user requirements.

Exclusive systems are produced according to very specific criteria, but this doesn’t mean they are immune to technological obsolescence. On the contrary, they require continuous improvements to enhance usability, incorporate functionalities, and promote the modernization of resources. However, these evolutions often face technical, financial, or operational limitations, such as the choice of technology used to develop the system.

An example of obsolescence is the AngularJS technology, launched in 2010 as a framework for web application development. The tool became popular for offering features that facilitated developers’ work. However, over time, this technology lost relevance compared to more advanced versions and was discontinued.

Without the possibility of technology support, systems developed in AngularJS became outdated. In this context, issues of performance, security, responsiveness, and usability became more critical, compromising primarily the users’ experience. Addressing these issues required migration to more updated and suitable technologies.

This was the challenge faced by one of the world’s largest pharmaceutical industries, which had an internally developed logistics control application in AngularJS. The system was designed to manage the entire flow of medication and substance samples, from collection and transportation to storage and distribution. Integrated with other internal software due to its connection to various operational processes, it was crucial for the tool to maintain high levels of performance.

To tackle this problem, the pharmaceutical industry enlisted the services of act digital, a specialist in technology solutions development with experience in system migration projects to the Angular platform. In this article, we detail how this project was executed, from planning to the achieved results.

Client: Innovative player in the pharmaceutical sector

The company that engaged act digital is one of the largest and most innovative pharmaceutical industries globally, employing over 3,900 professionals. Operating in the biotechnology market for over a decade, it is considered one of the best companies for professionals in scientific careers.

The group excels in research and development of therapeutic substances, focusing primarily on vaccine production to combat a wide range of diseases. Due to its scientific relevance and the high competitiveness of the market, the manufacturer has an internal technology team responsible for creating and maintaining dozens of operational and management systems used daily by thousands of employees.

Challenge: Technological Migration of the Logistics Control System

In this project, the pharmaceutical company faced daily challenges in using a system designed for operational processes and the control of sending samples of medications and substances.

Originally developed in AngularJS, the application was not responsive, limiting its adoption on mobile devices critical for logistics teams. User experience was also compromised by performance and usability issues, leading to operational inefficiency.

The situation was exacerbated by the fact that AngularJS technology had been discontinued and no longer received support. For the company, this scenario posed security risks and instability, potentially causing widespread failures and problems. This is because the system integrates with other internally used applications, making below-expected performance and damage to the user experience affect various processes.

Solution: Transition from AngularJS to Angular

Given the users’ difficulty in using the system created in AngularJS, the solution proposed by the act digital team was to migrate these applications to more recent versions of this technology. This transition was necessary to improve usability and speed in using the tool, further enhancing the performance of queries in the database.


The project was structured for a gradual migration, avoiding operational impacts, encompassing stages such as:

  • Diagnosis of the situation
  • Planning of actions
  • Refactoring, development, and migration of the application to the latest Angular version
  • Conducting analyses and verifications in a test environment
  • Deployment of the updated system for users

Applied Technologies

For the technological migration of the old AngularJS system, refactoring and development were necessary, utilizing more updated technologies. In this process, the following technologies were employed:

  • Angular
  • Node.js
  • Requelize
  • PostgreSQL
  • TypeScript
  • JavaScript

Results: Renewed User Experience and Performance Gains

The shift from AngularJS to Angular, along with the implementation of Node.js, PostgreSQL, and Sequelize technologies, has had a positive impact on the system, allowing users to experience more practical and agile navigation. Key outcomes include:

  • User Experience: The new application is more user-friendly, simplifying day-to-day use.
  • Responsiveness: A key objective was the ability to use the system on different platforms, particularly mobile devices.
  • Performance Gain: The system became more agile, surpassing the previous performance. Page loading time, which previously took 30 seconds, is now completed in less than one second.
  • Security and Reliability: Technological updates eliminated vulnerabilities associated with unsupported AngularJS, ensuring data security and system stability.
  • Facilitated Integration: Using the latest version of Angular enables easy integration with other emerging technologies and applications already in use within the company. Thus, the system is ready for future innovations or improvements.
