FYP

This is Our FYP. ｡ﾟヽ(ﾟ ´Д`)ﾉﾟ｡

It is a minimalistic cross platform mobile finanical management application. It comes in three screens:

• Home screen: Display and order stored transactions
• Add screen: Add new transactions to record. Recurring transactions supported!
• Trend screen: Predict future transactions based on regression models.

Important Notes

• Clone this project to your desired path
• Run yarn After clone
• ALWAYS USE yarn add to install packages, avoid using npm install
• Use Expo Go to Debug
• Run node index.js in /backend to start express server
• Add your expo go IP in help.js

General Structure

Frontend

• App.js is the main Javascript file that contains all the Pages to be navigate
• All 3 frontend pages should be contained in the directory "/frontend"
• All unique css should be included at the end of the corresponding frontend js, Read Homepage.js for the detailed formatting
• All common css should be included in "style.js", including fontSize, windowSizes etc

Backend

• index.js is the main Javascript file for express server which hosts fetch, add and delete endpoint via retool
• retool.js runs sql queries on retool, retrieving, adding and deleting records

Util

• filterSort.js contains functions for filtering and sorting transactions
• helper.js contains miscellaneous functions and some generic constants
• estimator.js contains regression models with pre-preprocessing functions
