RepoIF: desenvolvimento de uma plataforma web para gerenciamento e compartilhamento centralizado de materiais didáticos no IFPI - campus Picos.

Abstract

The dispersion of teaching materials across different digital channels can make their organization, location, and retrieval difficult in academic environments. In this context, this study aimed to develop and technically validate RepoIF, a web platform designed for the centralized management and sharing of teaching materials at the Federal Institute of Piauí (IFPI) - Picos Campus. The solution was developed to support the management of subjects, materials, classes, and assignments, as well as authentication, authorization, access control, administration, and moderation mechanisms. The research is characterized as applied, with a qualitative approach and exploratory and descriptive objectives. The development was conducted incrementally, involving requirements elicitation and specification, modeling, architecture definition, implementation, and validation. The solution uses React for the frontend, NestJS for the backend, PostgreSQL for structured data persistence, and Cloudflare R2 for file storage. Technical validation was performed through automated tests on the backend and frontend, complemented by integration tests with PostgreSQL, database migrations, and HTTP workflows. A total of 418 distinct backend tests and 159 frontend tests were executed and approved, resulting in 577 automated test cases. The usability of the interfaces was also analyzed through a heuristic inspection based on Nielsen's ten usability heuristics, using visual evidence from the platform's main functionalities. The results demonstrated the proper functioning of the behaviors covered by the test suites and the adherence of the analyzed interfaces to the adopted heuristic principles. It is concluded that RepoIF constitutes a functional solution within the established scope, providing resources for the organization, management, sharing, and retrieval of teaching materials in a structured environment.
