Express API & React App with PostgreSQL (Dockerized)

This repository demonstrates how to containerize a full-stack application using Docker Compose. The project consists of two main services:

• Express API Service: A Node.js Express server that provides API endpoints and connects to a PostgreSQL database.
• React App: A front-end application built with React.

Both services are orchestrated with Docker Compose for easy setup and deployment.
