Um estudo comparativo entre tecnologias de back-end: Node.js, Django REST Framework e ASP.NET Core

Abstract

In the current technological scenario, the development of Web applications, with a focus on back-end, has become an area of great importance and constant evolution. This layer plays a fundamental role in the architecture of a system. The choice of technology to be used for this layer of the project is essential to guarantee the performance, security and efficiency of the application as a whole. MOTIVATION: In this context, there are several technologies available that stand out for these purposes, each with its own peculiarities. It is crucial to understand the differences and characteristics of the most suitable tool for a given development context. However, as far as is known, no recent studies in the literature identify requirements and specific characteristics to guide the selection of a back-end technology in Web applications. OBJECTIVE: Considering this, this work compares the most used back-end technologies according to the most recent survey conducted by Stack Overflow: Node.js, Django REST Framework, and ASNP.NET Core. Therefore, it aims to provide relevant information for the choice of each of these tools in different systems and Web applications. METHODOLOGY: To this end, a bibliographical study and definition of criteria for theoretical comparison were carried out. Next, an API server was implemented in each of the frameworks to carry out tests and collect data and metrics, such as performance and performance in different scenarios. RESULTS: As a result of this study, it was possible to observe that, in the theoretical comparison, although some frameworks have native functionalities and compatibilities, others can be implemented through external libraries. However, in practical results, we observed that .Net’s resource consumption was significantly high, while Node.js and DRF showed low consumption and similar performance. With regard to response times, .Net showed the most efficient performance, followed by Node.js and DRF. BENEFITS: The results of this study benefit developers, companies and researchers. In this way, they will be able to observe the characteristics raised about the main back-end technologies and use them in their projects. In addition, it will serve as a reference point for researchers working in the field, contributing to the advancement in the development of back-end modules for Web applications.
