SmartController-SIH — Docker setup

This repository contains a Vite + React frontend and a Node/Express backend using SQLite for demo persistence.

Files added:

• Dockerfile.frontend — builds the frontend and serves it with nginx on port 80.
• server/Dockerfile — builds the backend image and runs node index.cjs on port 3000.
• docker-compose.yml — orchestrates frontend + backend; mounts ./server/data to persist the SQLite DB.

Quick start (requires Docker & docker-compose):

Build and start:

# From repository root
docker compose build --progress=plain
docker compose up -d

Visit:

• Frontend: http://localhost:8080
• Backend API: http://localhost:3000

Seeded demo credentials (created on first run):

• empID: admin
• password: admin123

Notes:

• For production, replace JWT_SECRET in docker-compose.yml with a secure secret and consider using a managed database (Postgres) instead of SQLite.
• To preserve DB between container runs ensure ./server/data exists and is writable by your user.

Troubleshooting:

• If the backend fails to start, check logs: docker compose logs backend
• To rebuild after code changes: docker compose up -d --build
