COURSI: criação de uma plataforma de cursos online

Abstract

The growing demand for distance learning platforms, driven by the widespread adoption of web technologies and the need for flexible access to knowledge, has motivated the development of robust solutions for managing and distributing digital educational content. This work presents the development of an online course platform designed for the creation, editing, publishing, and consumption of audiovisual materials, integrating modern technologies widely used in the software industry. The solution includes a backend built with Node.js and Express, a MongoDB database, role-based authentication, and integration with AWS services, particularly Amazon S3, for secure video storage. The frontend was developed using Next.js, employing hybrid rendering and client-side components to ensure interactivity and high performance. A key feature of the platform is its optimized video upload workflow, which uses pre-signed URLs and performs the actual upload only after the course publication is confirmed, preventing orphaned files and ensuring data integrity. The project adopts a modular and scalable architecture, aligned with current industry best practices, demonstrating its technical feasibility and practical applicability within the context of digital education.
