Desarrollo de una aplicación web progresiva para la gestión de reserva y pedidos del restaurante “EL FOGÓN DE COZ” implementando SSR

Abstract

The objective of the current thesis was the development of a progressive web application with the technique of rendering by the server that improved the quality of the management of bookings and orders of the restaurant "El fogón de Coz". We conducted a literature search regarding progressive web applications and the server-side rendering technique. In addition, we identified the processes of the restaurant. Subsequently, we proposed the development of the software with the Scrumban methodology, in planning and estimation 20 user stories and 2 technical stories were defined. We developed the application in 4 sprints of approximately 4 weeks each, with 8 hours a day; It was established to use the JavaScript programming language with the NextJS framework, the REST API architecture and the MySQL database manager. Afterwards, we evaluated the quality of the system using the criteria of efficiency and availability according to the ISO/IEC 25000 standard. For efficiency, the temporary behavior was evaluated using the Google Chrome speed profiling technique together with the statistical tests: Shapiro- Wilk and Wilcoxon to 41 order and booking record times that represent the restaurant's average daily record times. The Azure Application Insights tool was utilized to evaluate the availability in order to obtain the service time of the system. A quality application was obtained with a score of 9.99 out of 10, satisfying the user's needs and the ISO/IEC 25000 standard, as well as being functional because it meets all the requirements. In conclusion, it was determined that the use of PWA with SSR helps to improve this type of process. It is recommended to use the different sub characteristics of the standard and the use of frameworks to obtain a better-quality evaluation and to carry out the deployment in the cloud to reduce costs.
