Reingeniería de módulos de ventas, recaudos e inventario de APP a PWA con herramienta DevOps.

Abstract

The progressive web apps (PWA) have certain advantages over hybrid apps, such as not needing to go through the processes of publishing apps in stores, which save developers time and money. The project's main objective is to apply software reengineering in the sales, collections, and inventory modules of the mobile app of the company Manticore Labs to convert it to PWA through Scrum and Gitlab as a DevOps tool. The reengineering focused on visual aspects, business logic changes, architecture changes, frameworks, and documentation updates. The app was developed with the agile Scrum approach with the help of GitLab's DevOps tools. As for the frontend implementation, Angular and Ionic frameworks were used for backend Nestjs with MySQL database. The production deployment was done using Firebase services. For the usability tests, 12 people were polled using the System Usability Scale (SUS), getting an average result of 73.12 out of 100. This enables us to conclude that the app is friendly, except it needs to improve the user experience in new implementations. Therefore, it is concluded that the main objective of this project was fulfilled, which consisted of applying a reengineering to the mobile app in the sales, collections, and inventory submodules to a PWA app.
