Desarrollo de sistema web de un ecommerce con facturación electrónica : Desarrollo del Back-End.

Abstract

VIIIABSTRACTCurrently, Ecuador is experiencing an increase in electronic transactions in E-Commerce entities. However, the traditional purchase-sale model is still presented. This traditional model is caused by ignorance, limited Internet access and distrust of the seller/consumer. Another cause of this traditional model is the legality and security of "paperless" transactions in electronic means of payment.

For other way, Ecuador shows capacity in the development of an E-Commerce ecosystem. An example of this is the virtual business, where it makes its product known, creating trust with the client. The seller is favored with control and privacy in the issuance of an electronic invoice; therefore, it is fundamental in E-Commerce transactions, due to the simplification of procedures. The purpose of the project is to contribute to the retail sector of the city of Quito through an API REST for the E-Commerce web system with electronic invoicing. That allows, depending on the user's role, to validate the identification, store a catalog of products or create a list in the shopping cart. When making a purchase, users receive an electronic invoice,which is endorsed with the receipt via email of an electronic purchase-sale document.

During the construction of the API REST, Scrum is adopted as an agile methodology. The MVC pattern is integrated with the NestJS framework, which allows the agile and efficient generation of an API REST, and the integration of MongoDB as a database. This document presentsthe proceduresand results obtained, from the development of the project.
