VitrineJá: Plataforma Web de Divulgação e Comercialização de Produtos Regionais

Abstract

The absence of structured channels for the digital integration of local commerce, exacerbated by the high costs of traditional platforms and the limited technical maturity of merchants, reduces the competitiveness of small retailers and restricts consumers' access to regional products—a scenario clearly observed in the Center-South region of Piauí. This technical report presents the development of the VitrineJá platform, a full-stack software system designed to centralize the showcase of local commercial catalogs, operating as an informative digital storefront for small businesses and individual micro-entrepreneurs. The applied methodology relies on the iterative and incremental software engineering lifecycle, strictly separating system concerns through a headless, decoupled architecture. The technical ecosystem comprises a responsive interface built with Next.js and React on the frontend, asynchronously communicating with an independent RESTful API developed in Node.js and Express on the backend, whose data is persisted in a PostgreSQL relational infrastructure via Supabase. System validation was conducted through functional testing oriented to application requirements and core operational flows. It is concluded that the solution establishes a viable and scalable channel to mitigate technical and financial barriers to digitization, fostering the modernization and strengthening of regional local commerce.
