Flask + React Example

Basic example with a Flask API and a React frontend (Vite).

Backend

cd backend
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
python app.py

Flask will run on http://localhost:5000.

Frontend

cd frontend
npm install
npm run dev

Vite will run on http://localhost:5173 and proxy /api to the Flask server.
