⚙️ Setup Instructions

🔧 Backend Setup (/server)

cd server
npm install

Create .env in /server:

DB_HOST=localhost
DB_PORT=5432
DB_NAME=your_database
DB_USER=your_user
DB_PASSWORD=your_password
JWT_SECRET=your_secret
REDIS_URL=your_redis_url
PORT=5000

Run:

npm start

Run Unit Tests:

npm run test

---

🎨 Frontend Setup (/client)

cd client
npm install
npm start

---

🧪 Unit Testing (/server/tests)

• Framework: Jest + Supertest

• Tested:

  • ✅ Products Controller (Success + Failure)
  • ✅ Get Product By ID (Success + Failure)

• Run Tests:

  npm run test

• Sample Output:

  PASS tests/productsController.test.js
  PASS tests/getProductById.test.js

🐳 Dockerized Build (Client + Server)

1️⃣ Build Client (React)

cd client
docker build -t techmart-client .
docker run -p 3000:3000 techmart-client

2️⃣ Build Server (Node.js)

cd server
docker build -t techmart-server .
docker run -p 5000:5000 techmart-server

👉 Combine both using docker-compose for full-stack deployment.
