E-COMMERCE SYSTEM SUMMARY

In this final project, I chose to work on creating an E-commerce system application using nodejs This project makes use of ReactJS to support the development of a user interface We utilized features from React js such as component division and accompanying libraries to develop this e-commerce

As a result, the application not only functions as a sales platform but also has attractive graphics The server-side model that I applied for this development

is tree layers, which facilitated smooth teamwork due to clear differentiation

of functions

In addition, creating corresponding Router Controllers and Services helped me focus on writing code to handle user events However, we also encountered difficulties in the development process The first challenge was the lack of intellectual and human resources within the group, resulting in the initial inability to implement some functions Secondly, we realized that we still have not developed the ability to design software that can be considered optimal and suitable for the majority of users Despite these challenges, | effectively applied their knowledge of databases to model objects and design interfaces for an attractive and user-friendly application
