This project demonstrates a 3-tier application architecture using React for the frontend, Flask for the backend, and PostgreSQL as the database.

• Frontend: Built with React, a JavaScript library for building user interfaces.
• Backend: Powered by Flask, a lightweight WSGI web application framework.
• Database: Uses PostgreSQL, a powerful, open-source object-relational database system.

Ensure the following tools are installed on your system before proceeding:

• Docker and Docker Compose
• Basic understanding of containerized applications

Run the following command to build and start the application containers:

docker-compose up --build

This will build the Docker images and start the containers for the frontend, backend, and database.

In a new terminal, initialize the database by running the following commands:

docker-compose exec backend flask db upgrade

This applies the database migrations.

Next, seed the database with initial data:

docker-compose exec backend python seed_data.py

To stop the application and remove the containers, run:

docker-compose down

To restart the application, first stop it (if running) and then start it again:

docker-compose down
docker-compose up --build
