Overview

This PR adds Docker support to the project so the entire stack (frontend, backend, and MongoDB) can be run easily using Docker Compose. The goal is to simplify local setup and make the environment consistent across systems.

• Configured to connect to MongoDB using environment variables

MongoDB

• Added official MongoDB container
• Persistent storage enabled using Docker volumes

Docker Compose 🐳

• Added docker-compose.yml to run all services together

Networking

All services communicate through Docker’s internal network.
