Team-5 (DataWell)

Objective

We were chosen to help work with the nonprofit Wellfare, which aims to solve food insecurity and aims to reshape produce consumption and nutrition in low-income communities around the country. Our challenge was to use technology to develop a tool to create a seamless in-person customer experience, focusing on personalized pricing and membership capabilities. Additionally, this tool would not only enhance the shopping experience for customers but also those on the administrative side, allowing both sides to benefit and encouraging smoother communication among the Wellfare community.

Backend Architecture:

The backend is built with Express, NodeJS and MongoDB. We went with Express because of the ease of learning for those who did not know Express already. MongoDB also is fast to implement and perfect for our use case of a collection of users/products/feedback.

Frontend Architecture:

The frontend is built with TypeScript and React. A lot of people on our team knew React already, and it's also very easy to get up and running with it. We also styled our components using Tailwind CSS, a tool which we were less familiar with but nonetheless learned how to integrate. Its intuitive and utility-first approach to classes offered us the flexibility to collaborate on the front end without conflicting paradigms.

How To Run The Application:

The application is broken into two parts, front_end, and back_end.

cd into each folder separately and run npm install to install all dependencies.
Within the back_end server, create a file called .env and populate it with:
- PORT = 4000
- MONGODB = <your mongo database URL>
In the back_end folder, run nodemon server.js to start the server.
In the front_end folder, run npm run dev to start the server.
You should now be able to access the frontend on the port showing in the terminal where you ran npm run dev

Common Bugs/Fixes

TailwindCSS not building as expected after installation
- npx tailwindcss -i ./src/index.css -o ./dist/output.css --watch
Unwanted node modules in multiple branches
- npx npkill

Plans for future developments:

Continue implementing accessibility features
Improve mobile-version of dashboards
Implement language translations to accommodate non-English speakers
Migrate to an SQL/PostgreSQL database (MongoDB was partly used for convenience)
Add improved data visualization for insight on customer preferences and improved personalization (D3 library was under consideration)
