The frontend of this e-commerce marketplace is developed using React, Redux, webpack, and CSS. By incorporating Redux, the frontend development process is enhanced through a structured approach to managing application state, promoting data consistency, and facilitating efficient data sharing between components. The utilization of webpack for module bundling results in improved performance and faster loading times. On the backend, Nebula relies on Express, JWT, PostgreSQL, and Sequelize to ensure smooth data management. Express provides a solid foundation for constructing scalable web applications, while JWT ensures secure authentication and authorization processes. PostgreSQL serves as a dependable solution for storing and retrieving data, while Sequelize simplifies database operations with its convenient ORM capabilities. These technologies work together to establish a secure, efficient, and seamless backend infrastructure.
