REACT-NATIVE APPLICATION NGUYEN THANH NHU Student ID: 17110202 NGO HOANG MINH TAM Student ID: 17110218 Major: INFORMATION TECHNOLOGY Advisor: LE VINH THINH PhD Ho Chi Minh City, July 2021 ACKNOWLEDGEMENTS Our whole group was very fortunate to receive guidance and help from teachers and friends during the implementation process Now, the group would like to send this sincere thanks to Mr Le Vinh Thinh, who directly supported the group during the process of choosing the topic, guiding, commenting, and giving suggestions as well as providing reference materials survey Without the guidance and practical experience of the teacher, we think that this topic will be difficult to complete and complete on time Once again, the whole team would like to thank Mr Le Vinh Thinh We would also like to thank the teachers in the Department of High-Quality Training for their help in supporting the group's knowledge and answering questions Along with that, the group would like to thank their classmates for providing a lot of useful information and knowledge to help the group complete the topic better The time is limited, along with limited knowledge and many other surprises, so the omission is inevitable, so the team is looking forward to receiving your valuable comments from the teachers to improve their knowledge group is to be improved later We sincerely thank you! i TABLE OF

Chapter 5: IMPLEMENTATION AND TESTING 118 Chapter CONCLUSION Results Good teamwork skills, team communication skills, analytical work when working on short-term projects Skills in searching documents, skills in finding solutions on the internet for problems in the process of building projects Know how to apply a non-relational database (No-SQL) to build a database for a system, build a REST API web server that can serve web applications and application transformation, build web interface as Single Page Application using ReactJS Strengths and Drawbacks 6.2.1 Strengths - The website is designed with an easy-to-see and user-friendly interface - Simple ordering and payment - By effectively suggesting products (items) for each user, will help users feel more convenient and interested in the website And this will help increase the profit for the store 6.2.2 Drawbacks - Regarding the interface, there are still many shortcomings in the design, so the website is compatible with the computer interface and there are still many pages that are still not good in the design - In terms of functionality, due to the lack of expertise and experience, the processing is still quite slow, the interface loads for a long time - Regarding the data issue, the data is quite small, mainly used for testing, so there are some cases where the data is larger, leading to slow browsing or unreasonable display data Lesson learned - Learn how to manage basic source control, very good support in doing multiperson projects Chapter 6: CONCLUSION 119 - Learn the techniques of MERN Stack which are very popular nowadays - Learn the flow to verify users when they register, log in - Learn the connections between the Servers, the Python application runs machine learning algorithms to integrate into the MERN Stack project - Learn to deploy servers through Heroku Future works After building and developing features for about months, the team came up with some ideas to develop a strong system and overcome some limitations in the system However, because there was not enough time, the team saved this idea and implemented it when there was time - Integrate more payment gateways such as VNPAY, Ngan Luong, - Build more voice chatbot features - Image-based corresponding product search function - The function of issuing revenue slips of the day - Installment invoice issuance function Chapter

THEORETICAL BASIS React Native React Native is a JavaScript framework for writing real, natively rendering mobile applications for iOS and Android [2] Similar to React for the Web, React Native applications... or Java (for Android) [2] React Native also exposes JavaScript interfaces for platform APIs, so your React Native apps can access platform features like the phone camera, or the user’s location... are always timely and fast Therefore, the project team chose to carry out the topic "Research and build a cross -platform phone selling system (Mobile and Website) using MERN Stack and React Native"
