MVP Chat Web App

This project contains a minimal scaffold for a chat-based web application using a FastAPI backend and a React frontend.

Backend

The backend is located in the backend/ directory and uses FastAPI with SQLite via SQLAlchemy.

Create a virtual environment, install dependencies, and run the server:

cd backend
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
uvicorn app.main:app --reload

Frontend

The frontend is located in the frontend/ directory and was bootstrapped manually. To start the development server:

cd frontend
npm install
npm start

This will launch the React app which can interact with the FastAPI backend.

Features

• User registration with a username
• Submit an initial questionnaire answer
• Simple chat UI storing messages per conversation
• Endpoint to calculate a basic positivity score for a conversation
